US 2019/0378127 A1 · System and Method for Securing Transaction in a Blockchain Network

Abstract

A method for securing transaction in a blockchain network and a related system with a blockchain network. The blockchain network has information handling devices operably connected with each other. The information handling devices collectively maintain a blockchain ledger containing one or more transaction blocks with transaction information. The method includes validating a new transaction request to be added to the blockchain ledger. The validation includes digitally signing, at two or more of the information handling devices in the blockchain network, respectively, an interim block associated with the new transaction request, using a HASH value of the interim block and respective private keys of the two or more of the information handling devices. The method also includes verifying the one or more signed interim blocks for determining whether to add to the blockchain ledger a new transaction block containing the validated new transaction request and the at least two digital signatures.

Dependent claims

A method for securing a transaction in a blockchain network, the blockchain network including a plurality of information handling devices operably connected with each other, the plurality of information handling devices collectively maintaining a blockchain ledger containing one or more transaction blocks with transaction information, the method comprising:

validating a new transaction request to be added to the blockchain ledger, validation including digitally signing, with digital signatures, at two or more of the information handling devices in the blockchain network, respectively, an interim block associated with the new transaction request, using a HASH value of the interim block and respective private keys of the two or more of the information handling devices;
and
verifying the one or more interim blocks that have been digitally signed for determining, whether to add to the blockchain ledger a new transaction block containing the new transaction request that has been validated and the digital signatures.

A system for securing a transaction in a blockchain network, the system comprising:

a blockchain network having a plurality of information handling devices operably connected with each other and collectively maintaining a blockchain ledger containing one or more transaction blocks with transaction information wherein
each of the information handling devices of the plurality of information handling devices includes a processor,
two or more of the information handling devices are operated as signing devices arrange to digitally sign, with digital signatures, respectively, an interim block associated with the new transaction request, using a HASH value of the interim block and the respective private key of the information handling device so as to validate a new transaction request to be added to the blockchain ledger, and
one or more of the information handling devices are operated as verification devices arranged to verify the one or more interim blocks that have been signed for determining whether to add to the blockchain ledger, a new transaction block containing the new transaction request that has been verified and the digital signatures.
