Bitcoin Blockchain to Database Sync Process (blocks_updater) [cypto.bi Toolbox]
After performing the initial database insert using toolbox/db/blocks_inserter, new blocks will be received from the network. To keep the database in sync after the initial bulk insertion, toolbox/db/blocks_updater should be kept running on its own terminal. Difference From blocks_inserter Although similar in structure, blocks_updater works differently from blocks_inserter (go here for details on blocks_inserter). For […]
Will Bitcoin lose its #1 market cap crown?
Ethereum has just overtaken Bitcoin! But, wait! We’re not talking about market cap… As you’ve probably seen reported elsewhere, ETH now (Jun/2018) has more unique active addresses than Bitcoin. Is this a sign of something different looming in the horizon? Will Bitcoin end its 9 year reign as king of cryptocurrencies? Are there other cryptocurrencies […]
rpc/server.cpp – Commented Bitcoin Source Code
We now dive into one of the most exciting components of the Bitcoin Core source code. The RPC subsystem interconnects the connection manager, wallets, the storage subsystem and, most importantly, the front-end with which users interact. It’s basically the Bitcoin command interpreter embedded in the system and, from a developer’s perspective, the application programming interface. […]
Opinion: Decentralized blockchains can only survive having a valuable token, like Bitcoin, attached to them [Feb 2018]
We’ve heard this time and again, especially from folks in the financial sector: “blockchain is here to stay, Bitcoin not so much”. Is this really so? We disagree, and in this article we discuss the origins of Bitcoin and how the problem it solved only makes sense when there’s a reward for participants to join […]

SHA256 is an encryption routine which produces a unique and irreversible digest for a given message.
Bitcoin is the world's first viable decentralized cryptocurrency. It was released on January 2009 by Satoshi Nakamoto.
Hal Finney was a cryptographer who pioneered the development of Bitcoin. Finney received the first ever Bitcoin transfer.
Scrypt is a cryptographic key derivation function (KDF). In the context of cryptocurrencies, scrypt sometimes substitutes SHA256 as the hashing algorithm, most notably on Dogecoin and Litecoin
A sponge function is a computational method which is able to digest as much input as needed, while producing a fixed size output. Input can be of any arbitrary size, from one byte to terabytes of data. For example, a SHA256 hashing function is a sponge function that takes in an arbitrary amount of input data and always produces a single 256 bit output.
