These nodes each maintain a copy must be identified/identifiable Networks need to be permissioned High transaction throughput performance Low latency of transaction confirmation Privacy and confidentiality of transactions and data pertaining makes Fabric one of the better performing platforms available today both in terms of transaction processing and transaction confirmation latency, and it enables privacy and confidentiality of transactions
