An attestation ledger is often used to "attest" that a financial transaction happened or to certify the legitimacy of transactions or goods. A receipt, an invoice, or a bank statement is always used as proof.
An attestation ledger serves as a standalone corporate ledger for a single account. Individual accounts can be created using an electronic commerce account, such as a digital bitcoin wallet or a PayPal account.
Attestation ledgers serve as proof that financial transactions took place. They can also contain statements or pledges that offer proof to other parties that commitments have been made.
The ledger is a collection of records that operate in a distributed network based on blockchain technology.
Individual transactions are validated using attestation ledgers, which are a sort of public distributed ledger. A transaction ID can be inserted into the attestation ledger to certify the authenticity of a transaction. When connecting a host computer to a Blockchain Operating Ledger System, or BOLOS, attestation ledgers may be used to ensure that the device has not been tampered with.
Attestation ledgers can also be used by applications to demonstrate that they are running on a genuine ledger device.
