Noob Question about bitcoin!

Hi Guys! I'm Suraj from India.
I am looking for a crypto wallet for an android phone. That can help me to a transaction. I know there are hundreds of software available but I can't go with them.
Would you like to share some information or a tip? because I also want to purchase bitcoins.

Reminder from previous bull markets

Usually, bull markets attract a lot of new investors - although speculators should be the right word here - and as usual, a lot of them are going to be crushed a way or another.
First, before putting a single dollar, euro or whatever in the market, you should read a lot to know exactly what you're looking for.
Are you here for the tech and/or the cypherpunk ethos ? Great, there's lot of resources out there (my links are cleaned but as always, do your due diligence) :
Now, you've read and you want to put some skin in the game. Several exchanges are acceptable, a lot of aren't, be careful and assume that none really are (know that I won't post any ref links) :
This was for centralized exchanges aka CEX. Talking about custodial, you'll need wallets to store your (bit)coins. Always try to use non-custodial wallets, which means wallets that give you your private keys. This way, if the software goes down, you can always retreive your money. Now, I won't link to all the existing wallets but will advise you to buy hardware wallets (trezor or ledger but there are others) or to create (on off-gap computers) paper wallets you're able to store safely (against all risks, not only robbery but housefire). You also could use your memory with brain wallets but, my gosh, I wouldn't trust myself. For Bitcoin (or even Litecoin), Electrum software can do a good job (but save your keys).
AGAIN, DON'T KEEP YOUR SAVINGS ON AN EXCHANGE
Now, about trading : it's been repeated and repeated but don't chase pumps and altcoins. Yep, it's probably the fastest way to make money. It's also the fastest to lose it. I won't lie : I made good money during the 2017-bullrun and I took profits but I also forgot to sell some shitcoins thinking it would keep going up, now I'm still holding these bags (although I don't really care). I know that a lot forgot to take profits. Take profits, always take profits, whatever your strategy is. Don't fall for people trying to sell you their bags, for ICOs trying to sell you a product which isn't released yet and obviously, don't fall for people asking for your private key.
Also, know that there's two endgames : accumulating bitcoin or fiat. I'm rather in the first team but whatever your strategy is, take profits. (Yes, I know, some will say accumulating ethereum or something else). It's true that a lot of ethereum holders made a lot of money during the last bullrun (ethereum helped me make money too) but I'm really biased in favor of bitcoin (and monero). So, pick your coin but again, do your due diligence.
A lot of people here or there will talk about the best tech, the fact that bitcoin is old and slow. I would need another post to go further on this point but know that a lof of air flight systems are old too but reliable. Trustless and reliable is the point here.
This is the post from someone who bought bitcoin seven or six years ago, who lost part of them, who spent part of them (but don't regret this at all), who is still learning and I hope it will help others, although it would need a book to be complete.

Các ví tiền ảo uy tín nhất trong năm 2020

Các ví tiền ảo uy tín nhất trong năm 2020
Kể từ khi Bitcoin xuất hiện vào năm 2009, nó đã trở thành cái mà mọi người nghĩ đến đầu tiên khi nhắc đến tiền điện tử hoặc blockchain. Các loại tiền điện tử như Bitcoin có tính biến động cao nhưng chúng dường như không biến mất trừ khi đánh sập toàn bộ hệ thống Internet trên thế giới. Ngày nay một Bitcoin có giá trị hàng nghìn đô la. Khi các loại tiền điện tử như Bitcoin tiếp tục tồn tại hoặc thậm chí tăng giá trị, các cá nhân rất có nhu cầu quan tâm đến việc sở hữu chúng nhưng điều quan trọng là họ muốn biết được cách lưu trữ Bitcoin một cách an toàn. Để đáp ứng nhu cầu của những người muốn đầu tư vào Bitcoin một cách an toàn, chúng tôi đã tập hợp một danh sách các thiết bị lưu trữ và hay còn gọi là các ví tiền ảo uy tín nhất.
Có nhiều ví có tính năng rất tốt bao gồm khả năng lưu trữ nhiều loại tiền điện tử hơn mà không chỉ có Bitcoin, cũng như các biện pháp bảo mật bổ sung. Danh sách này không theo thứ tự cụ thể nào khác chỉ có đề cập đến ví nóng trước, nhưng điều đó không có nghĩa là ví nóng tốt hơn. Hiện tại, ví nóng được nhận xét là kém an toàn hơn để thực hiện các giao dịch nhanh chóng và ví lạnh là an toàn hơn để lưu trữ trong thời gian dài hơn. Trước hết chúng ta nên tìm hiểu về các khái niệm này trước khi chọn ví vì đó chính là chìa khóa để chọn được một phương tiện lưu trữ an toàn.

Các loại ví tiền ảo

Có 2 loại ví tiền ảo cơ bản đang được sử dụng trong thị trường lưu trữ tiền ảo.

Hot Wallets – Ví nóng

Ví trực tuyến còn được gọi là ví “nóng”. Ví nóng là ví chạy trên các thiết bị có kết nối internet như máy tính, điện thoại hoặc máy tính bảng. Điều này có thể tạo ra lỗ hổng bảo mật vì những ví này tạo ra khóa riêng cho tiền của bạn trên các thiết bị kết nối internet này. Mặc dù ví nóng có thể rất thuận tiện trong cách bạn có thể truy cập và thực hiện các giao dịch với tài sản của mình một cách nhanh chóng, nhưng chúng cũng thiếu bảo mật.
Điều này nghe có vẻ xa vời, nhưng những người không sử dụng đủ bảo mật khi sử dụng các ví nóng này có thể bị đánh cắp tiền. Ví dụ: Khoe khoang trên một diễn đàn công khai như Reddit về số lượng Bitcoin bạn nắm giữ trong khi bạn đang sử dụng ít hoặc không có bảo mật cho ví của mình và lưu trữ nó trong một ví nóng sẽ không phải là điều khôn ngoan.
Những ví này được sử dụng cho một lượng nhỏ tiền điện tử. Bạn có thể ví một ví nóng với một tài khoản séc. Sự khôn ngoan về tài chính thông thường cho rằng chỉ giữ tiền tiêu trong tài khoản séc trong khi phần lớn tiền của bạn nằm trong tài khoản tiết kiệm hoặc tài khoản đầu tư khác. Điều tương tự cũng có thể nói đối với ví nóng. Ví nóng bao gồm thiết bị di động, máy tính để bàn, web và hầu hết các ví lưu ký trao đổi.
Điều quan trọng cần lưu ý ở đây là việc giữ tiền điện tử trong ví trao đổi không giống như giữ nó trong ví cá nhân của bạn. Ví trao đổi là tài khoản lưu ký do sàn giao dịch cung cấp. Người dùng của loại ví này không phải là người nắm giữ khóa cá nhân của tiền điện tử được giữ trong ví này.
Nếu một sự kiện xảy ra khi sàn giao dịch bị tấn công hoặc tài khoản của bạn bị xâm phạm, tiền của bạn sẽ bị mất. Cụm từ “not your keys not your coin” là một khái niệm được lặp lại nhiều trong các diễn đàn tiền điện tử. Việc giữ một lượng lớn tiền điện tử trong bất kỳ ví nóng nào, đặc biệt là tài khoản trao đổi là không khôn ngoan. Mà thay vào đó, bạn nên rút phần lớn tiền về ví “lạnh” cá nhân của mình (giải thích bên dưới). Các “ví” trao đổi bao gồm Coinbase, Gemini, Binance và nhiều loại khác. Mặc dù các ví này được kết nối với Internet, có sự tấn công tiềm ẩn nhưng chúng vẫn rất hữu ích cho khả năng nhanh chóng thực hiện các giao dịch hoặc giao dịch tiền điện tử.

https://preview.redd.it/ixb613gcljx51.png?width=800&format=png&auto=webp&s=38b14e9069a3f727908f38abc7f42b21dabbe7f8
Các loại ví tiền ảo

Cold Wallets – Ví lạnh

Loại ví tiếp theo sẽ được đề cập ở đây là ví lạnh. Mô tả đơn giản nhất về ví lạnh là ví không được kết nối với Internet và do đó nguy cơ bị xâm phạm thấp hơn nhiều. Những ví này cũng có thể được gọi là ví ngoại tuyến hoặc ví cứng. Các ví này lưu trữ địa chỉ và khóa cá nhân của người dùng trên một thứ không được kết nối với Internet và thường đi kèm với phần mềm hoạt động song song để người dùng có thể xem danh mục đầu tư của họ mà không gây rủi ro cho khóa cá nhân của họ.
Có lẽ cách an toàn nhất để lưu trữ tiền điện tử ngoại tuyến là thông qua ví giấy. Ví giấy là một ví mà bạn có thể tạo ra từ một số trang web nhất định. Sau đó, nó tạo ra cả khóa công khai và khóa riêng tư mà bạn in ra trên một tờ giấy. Khả năng truy cập tiền điện tử trong các địa chỉ này chỉ có thể thực hiện được nếu bạn có mảnh giấy đó. Nhiều người cán mỏng những chiếc ví giấy này và cất chúng trong két an toàn tại ngân hàng hoặc thậm chí trong két sắt trong nhà. Ví giấy không có giao diện người dùng tương ứng ngoài một tờ giấy, vì vậy với mục đích của bài viết này, chúng tôi tập trung vào các phương pháp lưu trữ lạnh khác như ví cứng.
Ví cứng thường là một thiết bị USB lưu trữ khóa cá nhân của người dùng một cách an toàn. Điều này có lợi thế hơn so với ví nóng vì nó không bị ảnh hưởng bởi vi-rút có thể có trong máy tính của một người vì khóa riêng không bao giờ tiếp xúc với máy tính được kết nối mạng của bạn hoặc phần mềm có khả năng bị tấn công. Các thiết bị này cũng thường là mã nguồn mở, cho phép cộng đồng xác định độ an toàn của nó thay vì một công ty tuyên bố rằng nó an toàn để sử dụng.
Ví lạnh là cách an toàn nhất để lưu trữ Bitcoin hoặc các loại tiền điện tử khác của bạn. Tuy nhiên chúng yêu cầu thêm một chút kiến ​​thức để thiết lập. Điều cần thiết đối với bất kỳ ai quan tâm đến việc sở hữu tiền điện tử là tìm hiểu về cách lưu trữ an toàn và các khái niệm về cả ví nóng và ví lạnh. Một khi bạn nghĩ rằng bạn đã sẵn sàng để tiếp tục tìm hiểu thì các ví được liệt kê dưới đây là một số ví tiền ảo uy tín nhất trong ngành mà chúng tôi đã sưu tầm được.

Các ví tiền ảo uy tín trong năm 2020


https://preview.redd.it/sjijr0naljx51.png?width=800&format=png&auto=webp&s=58cc92596f7db2f5f5ba9e61728bbf6d2145c6ca
Các ví tiền ảo uy tín nhất năm 2020
Dưới đây là một số ví tiền ảo được người dùng đánh giá là uy tín và nên sử dụng trong năm nay. Cùng phân tích và đánh giá để có cái nhìn khách quan nhất khi lựa chọn sử dụng ví.

Exodus – Một trong các ví tiền ảo tốt nhất cho người mới bắt đầu

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: Trezor
  • Trao đổi hợp nhất: Có
Exodus là một ví điện thoại di động và máy tính để bàn có giao diện người dùng rất đơn giản và tích hợp sẵn một sàn giao dịch. Một trong những tính năng phổ biến nhất của Exodus là khả năng hoán đổi giữa một số lượng ngày càng tăng các loại tiền điện tử. Exodus hiện cho phép hoán đổi giữa hơn 100 loại tiền điện tử khác nhau.
Với sự đơn giản của nó, ví này rất phù hợp cho những người mới bắt đầu tham gia vào ngành tiền điện tử. Nó cũng có sự hỗ trợ tuyệt vời, đây là một tính năng cần thiết cho những người mới bắt đầu tham gia vào cái mà nhiều người sẽ coi là một thị trường khó hiểu.
Mặc dù nó rất tốt cho người mới bắt đầu, nhưng những người dùng cao cấp hơn có thể thấy nó thiếu một số tính năng. Đầu tiên, Exodus là một ví mã nguồn đóng. Điều này đi ngược lại đặc điểm của ý tưởng về Bitcoin và blockchain và có thể tạo ra một số lo ngại về bảo mật vì mã của nó không mở cho mọi người xem. Thay vào đó, người dùng dựa vào nhóm Exodus để đảm bảo không có lỗ hổng nào trong bảo mật ví của họ.Exodus có tùy chọn phí tùy chỉnh ngoài việc tự động đặt phí để đảm bảo giao dịch hoàn tất nhanh chóng.
Ưu điểm
  • Nhiều loại tiền điện tử
  • Trao đổi tích hợp
  • Hỗ trợ khách hàng tốt
Nhược điểm
  • Mã nguồn đóng

Electrum – Ví tiền ảo tốt nhất cho người dùng nâng cao quan tâm đến Bitcoin

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: thiết bị Trezor và Ledger
  • Trao đổi hợp nhất: Không
Electrum là một trong những ví Bitcoin ban đầu. Nó đã xuất hiện từ năm 2011, hai năm sau khi Bitcoin được tạo ra và đã thay đổi rất ít kể từ đó. Mặc dù ví này còn sơ khai về giao diện người dùng và cam kết chỉ dành cho Bitcoin, nhưng nó lại vượt trội ở chức năng chính này. Electrum cũng phù hợp hơn với người dùng cao cấp do các tùy chọn phức tạp của nó.
Electrum sử dụng mã nguồn mở, cho phép người dùng đặt phí giao dịch tùy chỉnh và có tùy chọn để chọn giữa Bitcoin kế thừa và Segwit. Nó cũng cung cấp cho người dùng khả năng xác định mức độ bảo mật mà họ muốn sử dụng. Ví dụ: bạn có thể tạo ví tiêu chuẩn, ví có xác thực hai yếu tố hoặc ví đa chữ ký. Electrum là ví hoàn hảo cho người nắm giữ Bitcoin cao cấp hơn, những người muốn có các tính năng bảo mật tuyệt vời và khả năng tùy chỉnh trong một bố cục đơn giản.
Ưu điểm
  • Khả năng đặt phí giao dịch tùy chỉnh
  • Mức độ bảo mật cao hơn hầu hết các ví nóng
  • Khả năng tùy chỉnh Seed Phrase
Nhược điểm
  • Giao diện người dùng rất cơ bản
  • Chỉ hoạt động với Bitcoin
  • Không hỗ trợ khách hàng

Mycelium – Một trong các ví tiền ảo tốt nhất cho người dùng di động

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: thiết bị Trezor và Ledger
  • Trao đổi hợp nhất: Có
Mycelium là một ví Bitcoin có mã nguồn mở và chỉ dành cho thiết bị di động. Mycelium hiện chỉ hỗ trợ Bitcoin. Về mặt nào đó, Mycelium khá giống với ví Electrum với một số điểm khác biệt là nó chỉ dành cho thiết bị di động còn giao diện người dùng được làm mới hơn ví Electrum và cũng có một sàn tiền ảo tích hợp.
Mycelium giống như Electrum là một trong những ví xuất hiện sớm hơn trong ngành tiền ảo. Cũng giống như Electrum, người dùng có thể đặt phí giao dịch tùy chỉnh để có thể chọn khoảng thời gian bạn sẵn sàng đợi giao dịch được hoàn thành. Mycelium cũng có một số tính năng thú vị hơn như hỗ trợ ví cứng, cho phép người dùng giữ Bitcoin của họ trong thiết bị lưu trữ ngoại tuyến trong khi vẫn sử dụng giao diện người dùng của Mycelium để xem tài sản của họ.
Ưu điểm
  • Khả năng đặt phí giao dịch tùy chỉnh
  • Khả năng sử dụng ví phần cứng
  • Phần mềm mã nguồn mở
Nhược điểm
  • Chỉ sử dụng được trên điện thoại di động
  • Chỉ hoạt động với Bitcoin
  • Có thể gây nhầm lẫn cho người dùng lần đầu

Ledger Nano X – Ví cứng tốt nhất

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 119
  • Trao đổi hợp nhất: Không
Ledger Nano X là ví cứng thế hệ thứ hai của Ledger, một công ty của Pháp đã tham gia vào ngành tiền điện tử trong vài năm. Sản phẩm đầu tiên của Ledger là Ledger Nano S, một trong những ví cứng đầu tiên trên thị trường và đã thống trị ngành tiền ảo trong một số năm.
Nano X giống một chiếc USB và kết nối với thiết bị của bạn qua cổng USB hoặc Bluetooth. Điều này có nghĩa là bạn có thể kết nối ví với thiết bị iOS hoặc Android của mình và không cần máy tính. Nó hỗ trợ tốt hơn 1.500 loại tiền điện tử. Danh sách này tiếp tục tăng lên mỗi năm khi cộng đồng yêu cầu hỗ trợ cho các loại tiền điện tử yêu thích của họ.
Mặc dù bản thân thiết bị là một chiếc ví cứng lưu trữ lạnh nhưng nhóm Ledger đã tạo ra phần mềm Ledger Live cung cấp giao diện người dùng cho tất cả tài sản của bạn. Điều này cung cấp cho người dùng khả năng thêm ví mới cho các loại tiền điện tử khác nhau vào thiết bị của họ và quản lý danh mục đầu tư của họ. Ví cứng Ledger đã và đang là ví phổ biến nhất trong ngành. Ledger cũng đi kèm với cáp USB Type-C để nó có thể được kết nối với máy tính để bàn hoặc điện thoại thông minh nếu không dùng được Bluetooth.
Ưu điểm
  • Ledger Live có giao diện người dùng trực quan và tiện lợi
  • Có thể có tới 100 ứng dụng khác nhau được lưu trữ đồng thời
  • Phần mềm nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
  • Sự thuận tiện khi kết nối Bluetooth
Nhược điểm
  • Một số người trong cộng đồng tiền điện tử tin rằng tích hợp Bluetooth là một phương thức tấn công tiềm ẩn, mặc dù có thể lựa chọn USB
  • Tính năng Bluetooth tăng thêm sự tiện lợi nhưng không mượt mà
  • Thiết bị Ledger chỉ cho phép bạn lưu trữ đồng thời một số lượng ví nhất định

Trezor Model T – Ví tiền ảo tốt nhất để lưu trữ một số lượng lớn tiền điện tử

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 170
  • Trao đổi hợp nhất: Có
Trezor giống như Ledger, là một cái tên đồng nghĩa với lưu trữ ví lạnh tiền điện tử. Model T của nó là thế hệ thứ hai của ví cứng mà họ đã tạo ra. Trezor Model T rất giống với Ledger, nhưng nó cung cấp cho người dùng khả năng truy cập các sàn giao dịch của bên thứ ba như Changelly và Shapeshift, trực tiếp trong giao diện trang web của nó. Mặc dù điều này khá thuận tiện nhưng nó khó có thể biện minh cho mức giá đắt hơn 170 đô la của mình.
Model T sử dụng màn hình cảm ứng, có thể dễ sử dụng cho người mới bắt đầu hơn so với các nút mà Model trước đã sử dụng. Trezor cũng có một khe cắm thẻ MicroSD, cho phép bạn sử dụng thẻ MicroSD để mã hóa mã PIN và bảo vệ thiết bị của bạn khỏi các cuộc tấn công.
Giống như Ledger Nano X, Trezor Model T cũng đi kèm với cáp USB Type-C để bạn có thể kết nối với điện thoại thông minh hoặc máy tính để bàn của mình. Hiện tại, Trezor Model T hỗ trợ gần 1.400 loại tiền điện tử khác nhau. Một số người cho rằng Model T an toàn hơn một chút so với Ledger Nano X do kết nối Bluetooth. Điều đó nói rằng, người dùng Ledger có thể chỉ cần tránh sử dụng Bluetooth nếu họ muốn an toàn hơn.
Ưu điểm
  • Giao diện người dùng dựa trên web với các trao đổi được tích hợp sẵn
  • Một danh sách khổng lồ các loại tiền điện tử được hỗ trợ
  • Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
  • Không giới hạn số lượng ví bạn có thể có đồng thời
Nhược điểm
  • Mặc dù nó là một ví cứng tuyệt vời, nhưng giá của nó có vẻ hơi cao
  • Màn hình cảm ứng nhỏ có thể khiến bạn khó gõ
  • Ví cứng có thể gây nhầm lẫn cho người dùng lần đầu tiên

Ledger Nano S: Lựa chọntốt nhất cho túi tiền của bạn

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 59
  • Trao đổi hợp nhất: Không
Ledger Nano S là thế hệ ví cứng đầu tiên được Ledger giới thiệu. Nó cũng là một trong những ví cứng đầu tiên từng được tạo ra. Nó tiếp nối ngay sau thế hệ đầu tiên của Trezor. Giống như người kế nhiệm, Nano S tương thích với hàng nghìn loại tiền điện tử. Nano S không đi kèm với cáp USB type-C, vì vậy người dùng sử dụng điện thoại thông minh hiện đại hơn có thể gặp khó khăn khi kết nối với thiết bị của họ.
Nano S về cơ bản giống với người kế nhiệm của nó là Nano X ở chỗ nó hỗ trợ cùng một danh sách các loại tiền điện tử và có quyền truy cập vào phần mềm Ledger Live. Các tính năng mà nó thiếu là kết nối Bluetooth và bạn có thể có bao nhiêu ví đồng thời hoạt động trên thiết bị của mình. Với Nano X, người dùng có thể lưu trữ đồng thời 100 ví. Với Nano S, bạn chỉ có thể lưu trữ tối đa 18.
Nano S chỉ có đủ dung lượng lưu trữ để tạo ví cho một số lượng tiền điện tử giới hạn tại một thời điểm. Nếu bạn xóa ví để thêm một loại tiền điện tử khác, bạn sẽ không mất tiền điện tử trong ví mà bạn đã xóa. Điều này là do tiền điện tử đó được lưu trữ trực tiếp trên blockchain.
Ví đã xóa và tiền điện tử trong đó vẫn có thể được nhìn thấy trong Ledger Live, nhưng ví sẽ không được nhìn thấy trên chính thiết bị Ledger. Điều này có nghĩa là nếu bạn muốn gửi hoặc nhận từ ví bạn đã xóa, bạn có thể phải xóa ví khác để có thêm dung lượng.
Điều đó nói rằng, Ledger Nano S vẫn là một chiếc ví tuyệt vời cho những người muốn lưu trữ tiền điện tử của họ một cách an toàn với một mức giá hợp lý. Nó cũng khá dễ sử dụng với Ledger Live, làm cho nó trở thành một sản phẩm lý tưởng cho người mới bắt đầu tìm kiếm cách lưu trữ an toàn và đơn giản cho một số ít tiền điện tử.
Ưu điểm
  • Ledger Live có giao diện người dùng trực quan và tiện lợi
  • Lưu trữ tiền điện tử an toàn với mức giá thấp
  • Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
Nhược điểm
  • Chỉ có thể lưu trữ tối đa 18 ví cùng một lúc
  • Nano S không có tính năng Bluetooth

Lời kết

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Tools, Infrastructure & Documentation

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

API

Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet.

Syscoin Bridge & How it Works (description and process flow)
Superblock Validation Battles
HOWTO: Provision the Bridge for your ERC-20
HOWTO: Setup an Agent
Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Что такое кастодиальные и некастодиальные криптокошельки?

Что такое кастодиальные и некастодиальные криптокошельки?
Можно ли обойтись одним криптокошельком?
Сохранить свои криптоактивы в целости и сохранности важно не меньше, чем выгодно приобрести их или заработать. По мере развития технологий и интереса к криптосфере все больше злоумышленников начинают охоту на монеты пользователей, а криптокошельки становятся одними из их излюбленных целей.
Начинающих криптоинвесторов зачастую вводит в заблуждение название этого инструмента: пользователи могут полагать, что их средства по умолчанию находятся в безопасности в любом криптокошельке, и предпочитают хранить монеты прямо на криптобирже. Но это небезопасно.
Если вам есть что терять, разделите монеты на те, которые понадобятся для быстрого проведения операций — их можно оставить в кастодиальных криптокошельках, и те, которые собираетесь хранить — их лучше сберегать в некастодиальных криптокошельках.
https://preview.redd.it/6sttmho3w6y31.jpg?width=1000&format=pjpg&auto=webp&s=a443da04d480786868b0d9985b8db80b6d00ed3b
Что такое кастодиальный криптокошелек?
Кастодиальные кошельки напоминают банковские инструменты. Их отличительное свойство — отсутствие у пользователя полного контроля над своими средствами, поскольку у оператора (кастодиана) есть доступ к приватному ключу. В этом есть свои плюсы. Например, утратив пароли или ключи, пользователь сможет снова получить доступ к средствам.
Кастодиальные кошельки есть у многих криптобирж (Coinbase, Kraken, Bitfinex, Binance, Poloniex, Bittrex, Coinex, Bitstamp и т. д.), торговых платформ и брокерских сервисов. Подобная интеграция упрощает работу с другими инструментами этих площадок, бывает выгодна при совершении транзакций (например, за счет отсутствия комиссий внутри экосистемы) и эффективна, если помнить, что фактически контроль за средствами принадлежит третьей стороне. К этой категории также относятся такие популярные криптокошельки, как Freewallet, Xapo, Crypto.com и др.

В чем недостатки кастодиальных криптокошельков?
Среди основных недостатков кастодиальных криптокошельков — доступ кастодиана к пользовательским средствам и риски их утраты в результате взлома, форка, по решению властей или суда. Неприятным опытом может оказаться и отсутствие доступа к собственным средствам во время проведения технических работ.
Например, летом 2016 года хакеры вывели почти 120 тысяч биткоинов с криптокошельков пользователей криптобиржи Bitfinex, которая хранила средства на горячем кошельке. Краже средств не помешали ни двухфакторная аутентификация, ни мультиподпись.
Ярким примером недостатков кастодиальных кошельков стало закрытие российской криптобиржи BTC-e. Летом 2017 года ФБР арестовало ее серверы и расположенные в США активы. Позже площадка перезапустилась под новым названием WEX и снова остановила работу, ее клиенты потеряли доступ к средствам.
Что такое некастодиальный криптокошелек?
Некастодиальным можно считать криптовалютный кошелек, сохраняющий за пользователем возможность полностью контролировать ключи и свои средства. К данной категории можно отнести аппаратные, мобильные, бумажные, десктоп- и веб-кошельки.
Самые популярные некастодиальные кошельки — это Abra, MyEtherWallet, Electrum, MyCrypto, BitGo, Wirex, Button Wallet, Exodus, ZenGo, Paytomat, Bitcoin.com, BRD, Blockchain, BTC.com, Electron Cash, Copay, Jaxx, Coinomi, Atomic Wallet, Guarda, Wasabi Wallet, Edge.
Некастодиальные криптокошельки абсолютно безопасны?
Нет. Некастодиальные криптокошельки имеют свои недостатки. Например, если потерять приватный ключ и фразу для его восстановления, средства будут безвозвратно утеряны (поэтому стоит быть особо осторожными с brainwallet, то есть с хранением данных в собственной памяти, или в бумажном криптокошельке — на бумаге). Вспомните историю о британском майнере, который в середине 2013 года по ошибке выкинул на свалку жесткий диск с добытыми за 4 года 7500 биткоинами.
Кроме того, некастодиальные криптокошельки интересуют и злоумышленников. Так, весной 2018 года популярный некастодиальный Ethereum-кошелек MyEtherWallet потерял 216 эфиров клиентов из-за атаки на DNS-сервер: хакеры перенаправили пользователей на фишинговый сайт и получили доступ к их приватным ключам.
Одними из самых эффективных и безопасных считаются аппаратные криптокошельки (Ledger, TREZOR, BitFreezer, Jaxx Liberty, KeepKey, Cool Wallet, Digital Box), хотя и они могут иметь уязвимости в коде, подвергаться физическому взлому или потеряться.
Как нужно работать с криптокошельком?
  • Сохраняйте ключи с помощью менеджеров паролей (LastPass, 1Password), а пароли к некастодиальным кошелькам — разными способами в нескольких надежных местах.
  • Для защиты от фишинга в веб-кошельки заходите по ссылкам, сохраненным вами в закладках. Если вводите адреса вручную, лучше делать это в новой вкладке браузера и с внимательной перепроверкой всех знаков.
  • Определите для решения каких задач вам нужны криптоактивы — и для минимизации рисков разделите их на несколько предварительно самостоятельно изученных криптокошельков.

Day 4: I will repost this guide daily until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. ARE YOU PART OF THE SOLUTION? News: Unconfirmed TX's @ 174K, more exchanges adding SegWit, Core prioritizes SegWit GUI

NOTE Just a daily repost because original OP Bastiat seems to be offline (due to holidays I guess). However, this is quite important as I see much misinformation on which exchanges use segwit or not. Please upvote for awareness.
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange
SELECTED TOP EXCHANGES BY SEGWIT & BATCHING STATUS
There are 2 different Segwit address formats.
  • p2sh - starting with a "3..."
  • bech32 - starting "bc1..."
Not many wallets/exchanges support bech32 yet and will claim the address is invalid if you try to send to it. bech32 ("native Segwit") is a mildly better solution compared to p2sh.

Day 5: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. User demand from this community can help lead to some big changes. Have you joined the /r/Bitcoin SegWit effort?

SUMMARY
Segregrated Witness (SegWit) was activated on the Bitcoin network August 24, 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work. If users demand SegWit now it will temporarily releive the transaction backlog while bigger solutions like Lightning are developed.

If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

Edit: Updated Segwit Exchange Status for Binance and HitBTC
submitted by Bastiat to Bitcoin [link] [comments]

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.

P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees

TL/DR
Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
  • SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
  • Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
  • Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
  • It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to existing wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
    Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
    Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
  • P2SH starts with "3..."
    bech32 starts with "bc1..."
Which addresses can I send from/to?
  • P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backwards compatibility
    bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
    Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
  • The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.
