What is Bismuth?

No ICO, no premine — mainnet since 1 May 2017.
Python, from scratch
Widely cited as the first blockchain written in Python — not a fork.
Account model
Signature-derived transaction IDs; arbitrary operation + openfield data.
Heavy3 PoW
CPU/GPU-friendly proof-of-work with a peer-reviewed difficulty controller.
Plugin ecosystem
Tokens, aliases, NFTs, DEX, naming, state channels — as building blocks.
Peer-reviewed
Consensus analysed in Modeling, Identification and Control (2017–2018).

📜 The story
10 Years of Bismuth
A cited retrospective on the project's architectural firsts (2017–2026): semantic data/meaning layering, an early plugin ecosystem and NFTs, on-chain sensor data before “DePIN” had a name, and a peer-reviewed proof-of-work difficulty controller.
🎙️ Press & coverage
A working bibliography of interviews, profiles, reviews and academic papers covering Bismuth (2017–2024) — with cleaned, link-rot-proof local copies of each piece.

Ledger bootstrap
A recent mainnet snapshot so a new node starts near the chain tip instead of syncing from genesis. A fresh node auto-bootstraps from this URL on first start; to apply it manually:
cd Bismuth
curl -L -o static/ledger.db.tar.gz https://bismuth.cz/ledger.tar.gz
tar xzf static/ledger.db.tar.gz -C static/
python3 node.py
⬇ Download ledger.tar.gz
⚠️ Full node needs the non-RSA signer libs
mainnet carries ed25519 / ecdsa transactions; without these the node rejects those blocks and cannot sync:
pip install coincurve ed25519
