minimal blockchain ever.
Assist you to develop blockchain core easily.
2018 OSS Grand Developers Challenge Award
Based on the following code: lhartikk/naivechain
As Blockchain-based service grew, so need of open source which assists developing blockchain core was drived. Although there are some open source projects like Bitcoin and Ethereum, those are difficult to learn to use.
You can gently solve the above problems by using
one-chain, simple implementation of blockchain core.
The one-chain is modularized by function—network, core, transaction, wallet, etc.— to achieve clarity.
Also, detail comments and documents are provided for studying and easy reusing.
Most of the code is written in a pseudo-code style to provide understanding by other language developers.
