Resumen de: US2024405990A1
Embodiments provide improved solutions for verifying one or more tokens provided via a token transaction on a blockchain. The token transaction is generated by an issuer and forms a link in a chain of token transactions which can be traced back to a minting transaction that was used by the issuer to generate the token(s). At least one certification element is provided in one or more token transactions within the chain, wherein the certification element certifies the authenticity of the token(s) by or on behalf of the issuer. A validating entity need only traverse the token's history chain back to a transaction which comprises a certification element rather than back to the mint transaction. Additionally, or alternatively, the disclosure provides improved solutions for melting and reminting the token when a pre-determined threshold, limit or specified value has been reached. Melting and reminting may comprise issuance on the blockchain of a new mint transaction subsequent to the original mint transaction in the token's chain of history, or replacement of an issuer-associated component such as an identifier which serves thereafter to identify the token, the issuer and/or the new or original mint transaction.

DEATs are published to a differentiated energy producer's modified private blockchain multi-signature wallet (mMSW) governed by the terms and conditions of a smart contract. DEATs may be transacted in a bilateral transaction between a buyer and seller under a transaction smart contract. Smart contracts are executed by one of more authorized signatories using their respective platform managed digital signatures (PMDS) instead of blockchain based public or private keys.

Techniques are described, as implemented by computing devices, to control access to transactions through use of cosigning based on tokenized reputation scores. This is performed by leveraging a blockchain such that tokenized reputation scores are generated based on amounts of cryptographic reputation tokens associated with blockchain account addresses associated with applicant and co-signer service provider accounts. Transactional functionality is made available to an applicant service provider account having an insufficient tokenized reputation score by using a co-signer service provider account having a sufficient tokenized reputation score to at least partially back an obligation of the applicant service provider for a transaction.
