radix-engine-library is an engine for real-time, distributed state machines.

Application for proposals using blockchain with MultiChain.

It simulates a shared/distributed ledger (a.k.a. block chain) network of nodes (full nodes/miners and thin clients) to better understand how this type of protocols work (e.g. Bitcoin, Ethereum, etc)
