Abstract
News editors obtained the following quote from the background information supplied by the inventors:“A blockchain is a decentralized ledger of transactions built upon a combination of cryptography techniques(e.g., secret keys, hash functions, etc.), consensus mechanisms (e.g., proof-of-work, proof-of-stake, etc.),and computer networks (e.g., peer-to-peer (P2P) networks, the internet, etc.). The blockchain storesinformation electronically, grouped together into a series of subsets of the information called “blocks.” Theinformation may be maintained by a network of computers using cryptography and consensus mechanisms,which make the records difficult to hack or alter. Specifically, the integrity of the information in eachblock may be maintained through one-way cryptographic functions that make the information immutablefor practical purposes.
