beyond indexers trustless application data snapshots
summary
Describes a trustless snapshot system that appends events into an on‑chain hashed list and publishes periodic root snapshots so large off‑chain topology files (payment‑channel graphs) can be downloaded from FTP/torrent and verified against Ethereum. Claims an orders of magnitude improvement in index speed for HOPR node syncs while costing a single on‑chain hash plus a one storage slot read/write (about 20,000 gas per snapshot); open‑source base contract and working implementation are available.
