Chainsnap is a project for maintaining blockchain snapshots. This project enables the storing and retrieval of snapshots for blockchain projects including Filecoin, Polygon, Ethereum, Binance Smart Chain, and Near.
Main Features:
-
Full backup of the completed and minimal snapshots (if it exists) of each chain every once in a while
-
Maintain the original download links of the snapshots and the metadata (CSV and JSON format) after preprocessing.
-
Each piece will be sent to storage providers in the Filecoin network through Swan Client, and the metadata of the deal (including filename, dealCID, MinerID, etc.) will be maintained in the repository;
-
Mint deal metadata to an NFT in the Opensea platform, everyone can see it at any time
How to retrieve it:
- Get all pieces of each snapshot from snapshot metadata
- Get storage providers that store all pieces from the deal metadata
- Fetch all the pieces using the Lotus retrieval function
- Merge all pieces to the complete snapshot
It is worth noting that all deal metadata will be mint to the Opensea platform through multichain storage to ensure that will never be lost
