Abstract:
The concept of a blockchain was invented by Satoshi Nakamoto to maintain a distributed ledger for an electronic cash system, Bitcoin. Even though very secure, blockchain systems have serious deficiencies in some important performance measures, including transaction throughput, confirmation latency and confirmation reliability. To this end, distributed ledger technology with underlying directed acyclic graph (DAG) structure has been proposed to overcome the scalability bottleneck of blockchain systems.
In this talk, we present Canonchain, a new DAG based distributed ledger technology. We provide rigorous analysis to the consensus algorithm, which utilizes non-anonymous reputable entities, called witnesses. Our new protocol can achieve 1) more than 2000 transactions per second (TPS); 2) less than 20 seconds transaction confirmation time and 3) eventual total ordering of all transactions.
