Building a Blockchain in Erlang
summary
Aeternity implements a blockchain in Erlang with an Ethereum-compatible bytecode VM, an ML-like contract language called Sophia contract language, and a transaction-oriented API of named types (oracle, name, channel ops) handled by a pluggable behavior with check and process callbacks. Consensus uses Bitcoin NG style key blocks plus microblocks every 2 seconds to reach ~20–40 sustained tx/s in tests and a theoretical 100, and a memory-hard Cuckoo Cycle proof-of-work; uses Noise for encrypted node links and avoids floating point in contracts.
