Immutable Ledger Backups
Immutable ledger backups involve maintaining a permanent, unchangeable record of all transactions and system states that can be used to reconstruct a protocol's history in the event of a failure. Because blockchains themselves are immutable, this often involves storing off-chain data, such as order books or user balances, in a decentralized or redundant format that cannot be tampered with.
These backups are crucial for derivative exchanges, as they allow for the reconciliation of positions and collateral in the event of a platform outage or database corruption. By ensuring that the data is both immutable and distributed, protocols can provide a high level of transparency and trust, as any participant can verify the integrity of the system.
This practice is essential for maintaining market stability and preventing the loss of financial records.
