Decentralized State Data Indexing

exSat will synchronize Bitcoin's UTXO data, which is over 80GB, through two parts to establish an on-chain structured index of the data:

• For the blocks before a designated block height, historical block data will be synchronized through snapshots to build an index of historical data in an open-source and verifiable manner.

• For blocks after the designated block height, real-time block data will be synchronized, validated, and put on-chain through Synchronizers and Validators.

This allows for establishing a trustworthy index of UTXO data, providing a simpler, more convenient, and trusted approach for complex on-chain operations of smart contracts.
