A proof-of-reserves and attestation dataset generated as a byproduct of auditing tokenised-asset issuers. Three layers: (1) Merkle-tree liability trees — a full customer-balance extract from an exchange or issuer is hashed into a Merkle tree whose root is published inside the signed attestation report, sealing that dataset against tampering and linking report to tree, with individual customers able to cryptographically verify their own inclusion without revealing anyone else's balance; (2) on-chain reserve attestations that push off-chain reserve facts onto blockchains through the Chainlink oracle network for smart-contract use — bank balances, gold troy ounces held in vaults, treasury-bond CUSIPs and maturity dates, and real-estate appraisals; (3) real-time monitoring that aggregates bank APIs, PDF reports and multiple chains into continuously regenerated attestation reports, plus an auditors' workbench performing multi-chain historical balance queries at a stated snapshot timestamp across hundreds of addresses at once and issuing audit confirmations. Named client logos include ArchBlock.
