Proofs of Concept
POCs explore targeted questions about Erigon's architecture. They are experimental by design — the goal is to validate a hypothesis, identify blockers, and produce a concrete recommendation for the production path forward.
| POC | Question | Status |
|---|---|---|
| Sparse Snapshots | Can an Erigon node process blocks using only on-demand BitTorrent piece fetches, without downloading complete domain files? | Validated — 19 blocks processed. Blocked on caching layer. |
| QMTree Commitment | Can an append-only binary Merkle tree indexed by txNum replace the hex patricia trie as a state commitment scheme? | Working PoC on qmtree branch. Live data on Hoodi testnet. |
