Welcome to our time machine. Here thou shalt find crypto lore of the ancient past.
Learn about cryptos which are no longer with us (see also Dead Coins section), the early beginnings of the crypto movement, the political ideas/movements that influenced cipherpunks and crypto hackers to create the first cryptocurrencies, interesting facts from the early days and other stuff that help us better understand where cryptocurrencies came from and where we might be headed next.

Why are there so many cryptocurrencies?
Why so many cryptocurrencies? Are all of them as complex as Bitcoin? Currently, the Crypto.BI cryptocurrency list has over 1993 entries. What's behind this crypto diversity?
Who is Satoshi Nakamoto?
Who is Satoshi Nakamoto? We don't know and neither does anybody else. But we've got some ideas about who he might be, since there aren't too many people out there who possess the ...
Introduction to our commented Bitcoin source code section
Below you’ll find the main commented Bitcoin source code sections (sorted by section name and filename). Core amount.h – Defines the CAmount typedef, implements minimum and maximum valid amount range check. base58.cpp – The encoding function used for Bitcoin addresses. Base58 removes some potentially ambiguous characters from Base64 so Bitcoin addresses can be written down […]
ELI5 PSBT – Partially Signed Bitcoin Transactions
Trustless operation is one of the key concepts behind cryptocurrencies. The idea is that you should not have to personally meet, or trust your peers, in order to perform successful transactions. Experienced crypto users may take this concept for granted, but come to think of it – every real world transaction before cryptocurrencies came about […]
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 […]

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.
SHA256 is an encryption routine which produces a unique and irreversible digest for a given message.
Cipherpunks or cypherpunks are individuals who believe in cryptography as a tool to promote privacy and individual sovereignty. Cipherpunk ideals can be identified at the early roots of cryptocurrency development.
First Generation Cryptocurrencies
The first generation cryptocurrencies was spawned by Bitcoin. Several Bitcoin forks exist on this generation. Most 1st generation coins simply copied the Bitcoin source code while modifying the encryption algorithms and total coin supply.
Second Generation Cryptocurrencies
The second generation of cryptocurrencies added on-chain smart contracts and fully featured contract programming languages. Ethereum, which is the most notable 2nd generation cryptocurrency, brought smart contracts and introduced tokens to the masses, spawning the wave of ICO's from 2014 onwards.
Third Generation Cryptocurrencies
Third Generation Cryptocurrencies are still being developed. These include everything from second gen cryptos, plus on-chain governance, delegated Proof of Stake consensus and native compliance features. Cardano is a notable example of 3rd gen cryptocurrency project.
ERC20 is an Ethereum standard interface for cryptocurrency token implementation. A smart contract which complies with the ERC20 standard automatically gets detected as a token on the Ethereum blockchain. The ERC20 standard sparked an entire industry where creating a new coin (token, to be accurate) was a matter of publishing a smart contract to the blockchain.
