Overview & Challenges of building a Blockchain
summary
Elixir implementation of the aeternity protocol uses cuckoo cycle PoW for lightweight mining, creates key blocks every three minutes for leader election, and adds on-chain oracles plus a human-friendly naming system. Multiple smart-contract languages include Sophia (ML dialect) and Solidity; state channels are planned to reduce on-chain fees. The production codebase ties Elixir gen_servers, umbrella apps, NIFs and native libs (libsodium, RocksDB, Patricia trees), and a 12‑person Elixir team reaches productivity in about 2–3 months.
