We are creating a huge body of articles and videos that explain everything you need to know to be able to build apps on Bitcoin SV, with or without Money Button. In the first documentation group, we outlined basic technical preliminaries including numbers, elliptic curves, and basic encoding tools that are used in Bitcoin and applications based on Bitcoin. In this second…
There is no limit to the amount of data you can store on the Bitcoin SV blockchain. Currently, the miners are charging 1 satoshi per byte which at current market prices is about 7 US cents per 100 KB. Because opreturn data sizes larger than 100 KB are not being mined, it is necessary to break up large files into pieces less…
In order to help people build applications with Money Button and with Bitcoin SV (BSV), we have started a documentation series that includes written documentation on the Money Button Documentation page and a video series on YouTube. We have completed the first set of videos, which are all of the low-level technical preliminaries necessary to be able to understand Bitcoin (or at…
If you swipe Money Button a lot in a short period of time, you may get an error and have to wait about ten minutes before you can swipe again. This “speed limit” error is not related to Money Button itself, but is caused by a scaling limitation in the Bitcoin SV node software. It is not possible to send more than…
Money Button is like the Facebook like button, but it’s money. It’s very easy for developers to build it into apps, and it’s very easy for users to pay with it. Transaction fees are zero, and payments cannot be blocked, reversed, frozen or inflated away. As we add features like support for giant OP_RETURN data making immutable data storage apps possible, we’re happy…
We would like to publicly thank the BBC for writing about the events of last week. We are saddened that criminals have used the blockchain. We believe these events present us with an opportunity to take a stand in favor of basic human decency, moral behavior, and law, and against criminality. The blockchain was invented in 2009 by a pseudonymous individual named…
It is not possible to censor the blockchain, but businesses that write to and read from the blockchain have a moral and legal obligation to moderate morally reprehensible and illegal content. Yesterday, an anonymous user posted illegal content to the blockchain using Money Button. Money Button does not provide any mechanism to interpret or display this content, but BitcoinFiles.org does. BitcoinFiles.org received a notice…
We are happy to announce that as of today, Money Button supports giant OP_RETURN data sizes of up to 100 KB, making it possible to store files such as images, audio, video, documents, and any other type of data in a single transaction on the Bitcoin SV (BSV) blockchain. Money Button provides this service completely for free, and the only fees paid…
Today we’re happy to announce the launch of bsv: a library for cryptography, key management, and transaction building for Bitcoin SV (BSV). bsv is based on bitcore-lib-cash, which itself is a fork of bitcore-lib. Because BitPay does not currently maintain a javascript library for Bitcoin SV, we have decided to maintain the library ourselves for the Bitcoin SV community. bsv is nearly…
Money Button now supports the original address format that starts with a 1. We we no longer display cashaddr anywhere, but we do support cashaddr for backwards-compatibility in the button and for withdrawals. If you are already using Money Button, there is nothing you need to do — your buttons now support the original address format. The cashaddr address format was an…
