The blockchain network has a plurality of information handling devicesoperably 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 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
