Corda

Corda is a "blockchain" technology architecture. Both sides of the transaction jointly select a notary with high degree of feasibility so that the notary can verify the validity and uniqueness of the data. If the notary confirms that the deal is feasible, the deal will be reached. At this point the transaction notary's books will be synchronized. The advantage of doing this is to make the transaction more efficient under the conditions of ensuring security.

Fabric: The newly defined concepts include chain, peer, channel, and consensus services. Peers can participate in multiple books so that the fabric has scalability, peer transaction isolation, account isolation and etc.
