Abstract: An example method of configuring a plurality of aspects of a system includes providing, by a computing system, a control smart contract and a plurality of subordinate smart contracts on a blockchain, wherein each subordinate smart contract receives a respective input regarding a respective one of the plurality of aspects and outputs a respective decision, and wherein the control smart contract controls a configuration process incorporating the subordinate contracts according to the decisions of the subordinate contracts. The method further includes conducting, by a computing system, the configuration process according to the control smart contract; and configuring the aspects of the system according to the decisions of the subordinate smart contracts.

Abstract: Methods and systems described herein may implement blockchain asset authentication. A verification system may generate an encryption key associated with a digital asset, wherein the digital asset is associated with a first entity. The verification system may sign the digital asset using the encryption key. The verification system may generate a first key and a second key based on the encryption key, wherein the first key and the second key are part of a set of multi-party secret keys. The verification system may send the first key to the first entity and store the second key on the verification system. The verification system may receive a request to authenticate the digital asset. The verification system may in response to the request to authenticate, generate the encryption key based on the first key and the second key. The verification system may authenticate the digital asset based on the recreated first secret.

Abstract: Methods and systems for enabling off-chain transactions via a non-fungible token (NFT) marketplace are provided. A plurality of digital wallets associated with a service provider are provided with access to the NFT marketplace. The NFT marketplace corresponds to a decentralized blockchain associated with an entity that is different from the service provider. A request to perform a transaction involving a purchase, via the NFT marketplace, of an NFT associated with a specified source address is received from a first user of the service provider associated with a first identifier and a first digital wallet. Responsive to determining that the specified source address corresponds to a second user of the service provider associated with a second identifier and a second digital wallet, an identifier associated with the NFT is updated from the second identifier associated with the second user to the first identifier associated with the first user.

Abstract: Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, a system, comprises a non-transitory memory comprising instructions; and one or more hardware processors coupled to the non-transitory memory and configured to read the instructions to cause the system to perform operations comprising: detecting a request from a first user to access one or more digital assets of a first digital wallet of a second user; in response to detecting the request, determining whether to provide access to the one or more digital assets to the first user based on one or more factors, wherein the one or more factors includes a location of the first user, a location of the second user, or one or more characteristics of the first user; and restricting the first user from accessing the one or more digital assets based on the one or more factors.

Abstract: Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, A system, comprising a processor and a non-transitory computer-readable medium having stored thereon computer-executable instructions that are executable by the processor to cause the processor to perform operations comprising: receiving a set of biometric identifiers; in response to receiving the set of biometric identifiers, validating the set of biometric identifiers; in response to validating the set of biometric identifiers, encoding, using a synthesizer, the set of biometric identifiers with a digital-key to generate a multi-factor signature; and causing a block-chain transaction to be executed using the multi-factor signature.
