A simple and flexible method to sign arbitrary OP_RETURN data with Bitcoin ECDSA signatures. Authors: Attila Aros, Satchmo Special thanks to Monkeylord and Unwriter for feedback and ideas. Note: Use the bitcoinfiles-sdk to build, sign, and verify document signatures. Inspired by techniques described by Monkeylord at https://github.com/monkeylord/bitcoin-ibe Built on top and leveraging Bitcoin Data Protocol by Unwriter at https://b.bitdb.network/ […]
C://_ Content Addressable Files over Bitcoin
C:// is an immutable URI scheme for referencing B:// protocol files, a simple Bitcoin file storage protocol. The file system is constructed from Bitcoin transactions, and is instantly serviced through HTTP/HTTPS endpoint. Why? Having immutable files on the blockchain is not enough, since you still have to trust the server that is providing the file itself. However, […]
Bit://
There are 3 parts to this protocol solution: Generic URI Scheme: A new expressive URI scheme that can custom-reference any Bitcoin app protocol object on the blockchain. Decentralized Router: A decentralized routing engine that maps the generic URI scheme to real world service providers who implement each protocol, using Bitcom. Authentication: A two-way mechanism to connect service endpoints to […]
BitcoinSV – BitSocket
Bitsocket Is a powerful bitcoin push notification service for building real time bitcoin applications. Bitsocket lets you subscribe to any pattern of realtime bitcoin transactions through Bitquery and build apps that are driven by the event. Using bitsocket as a bitcoin message bus, it is possible to construct various bitcoin application architectures through message piping: Bitcoin AppBuild applications […]
BitcoinSV – BitDB
BitDB Is an autonomous database that continuously synchronizes itself with Bitcoin. BitDB stores every bitcoin transaction in a structured document format that can be queried against like a regular database. With a simple MongoDB query, anyone can easily query, filter, and build powerful decentralized applications on Bitcoin. BitDB is an autonomous database that continuously synchronizes […]

Blockchain History
In order to understand Blockchain, it is necessary to know its history To understand a bit the history of blockchain, we will break down its principles or basic technological foundations that compose it in the different areas of functionality. Blockchain is a single integrating technological element, which becomes a layer whose main purpose is to […]
