About Bitcoin Anchoring
The Swiss Ledger Bitcoin anchoring system uses OpenTimestamps to provide cryptographic proof of data existence at specific timestamps on the Bitcoin blockchain.
Each anchor represents a range of blocks whose data has been verified and timestamped, ensuring data integrity through Bitcoin's immutable blockchain technology.
Learn more about Swiss LedgerEvery week, a scheduler performs a concatenation of Swiss Ledger block hashes into a single string. This concatenated data is then hashed using SHA256 to create a unique fingerprint representing that week's blockchain activity.
The resulting SHA256 hash is sent in a transaction to the Ethereum blockchain, where the smart contract emits an Anchoring event containing the start block, end block, and hash value, providing immutable proof of Swiss Ledger's state.
