The peers are diverged into two distinct roles – Endorser & Committer. As an endorser, the peer will simulate the transaction and ensure that the outcome is deterministic or stable. As a committer, the peer will validate the integrity of a transaction and then append to the ledger. Now confidential transactions can be sent to specific endorsers and their correlating committers, without the network being made cognizant of the transaction. Additionally, policies can be set to determine what levels of “endorsement” and “validation” are acceptable for a specific class of transactions. A failure to meet these thresholds would simply result in a transaction being thrown out, rather than imploding or stagnating the entire network.

Additionally, policies can be set to determine what levels of “endorsement” and “validation” are acceptable for a specific class of transactions. A failure to meet these thresholds would simply result in a transaction being withdrawn, rather than imploding or stagnating the entire network. This new model also introduces the possibility for more elaborate networks, such as a foreign exchange market. Entities may need to only participate as endorsers for their transactions, while leaving consensus and commitment (i.e. settlement in this scenario) to a trusted third party such as a clearing house. The consensus process (i.e. algorithmic computation) is entirely abstracted from the peer. This modularity not only provides a powerful security layer – the consenting nodes are agnostic to the transaction logic – but it also generates a framework where consensus can become pluggable and scalability can truly occur. There is no longer a parallel relationship between the number of peers in a network and the number of consenters. Now networks can grow dynamically (i.e. add endorsers and committers) without having to add corresponding consenters, and exist in a modular infrastructure designed to support high transaction throughput. Moreover, networks now have the capability to completely liberate themselves from the computational and legal burden of consensus by tapping into a pre-existing consensus cloud. -As V1 manifests, we will see the foundation for interoperable blockchain networks that have the ability to scale and transact in a manner adherent with regulatory and industry standards.
