[0021] Glossary of terms

[0022] Blockchain - A public ledger of all transactions for a blockchain-based currency. One or more computing devices may include a blockchain network that may be configured to process and record transactions as part of blocks in the blockchain. Once a block is finalized, the block is added to the blockchain and thus updates the transaction record. In many cases, a blockchain may be a chronological ledger of transactions, or may be presented in any other order that may be suitable for use by a blockchain network. In some configurations, transactions recorded in the blockchain may include a destination address and an amount of currency such that the blockchain records how much currency is attributable to a particular address. In some cases, additional information such as source address, timestamp, etc. may be captured. In some embodiments, the blockchain may also consist of additional and in some cases arbitrary data that is validated by the blo...

Abstract

A method of signing a blockchain transaction using a digital signature, comprising: generating a domain key pair including a domain private key and a domain public key, wherein the domain public key is signed after generation; receiving a plurality of member a public key, wherein each member public key is received from an associated member of the blockchain network, and each member public key is a public key in a key pair comprising the member public key and a member private key corresponding to said associated member; signing each member public key using said domain private key; receiving a transaction block from a particular member of said blockchain network, wherein said transaction a block comprising a plurality of blockchain transaction values ​​and a hash signed using the member private key corresponding to the particular member; signing the received transaction block using the domain private key; and sending the signed transaction block .

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of US Patent Application Serial No. 14 / 976,331 filed December 21, 2015, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to the use of digital signatures to sign blockchain transactions, and in particular, to the use of digital signatures for the signing and verification of blockchain transactions by multiple entities for increased security and more efficient verification. Background technique [0004] Blockchain serves as a public ledger for electronic transactions. Each new block of transactions added to the blockchain provides further verification of previous blocks, making the blockchain stronger as it grows over time. Because past blocks in the blockchain never change, and because the blockchain cannot lose or discard past blocks, the blockchain becomes an immutable but publicly accessible record of a...
