Release master 2 Contents CHAPTER 1 Introduction In general terms, a blockchain is an immutable transaction ledger, maintained within a distributed network of peer nodes. These nodes each maintain a copy identified/identifiable • Networks need to be permissioned • High transaction throughput performance • Low latency of transaction confirmation • Privacy and confidentiality of transactions and data Fabric one of the better performing platforms avail- able today both in terms of transaction processing and transaction confirmation latency, and it enables privacy and confidentiality of transactions
