The Accountable

When blockchain participants are held responsible for their actions.

Supported by

The University of Sydney
The Australian Research Council 

Built by experts

The expertise of the Concurrent Systems Research Group is in the theory and practice of distributed computing. With many years of experience, the group members have defined a new problem, called the Blockchain Consensus with French and Spanish researchers.

For performance

The Red Belly Blockchain offers unprecedented throughput of more than 600 thousands transactions per second (an order of magnitude faster than Visa). Its safety aspect is of invaluable importance for critical industries, like banking, and offers performance that scales horizontally.

With security in mind

Our researchers in collaboration with Data61-CSIRO, demonstrated the limitations of forkable blockchains (like Bitcoin and Ethereum) and how one can issue a Balance Attack to double spend, which consists of stealing assets from the blockchain.

How to
hold participants accountable

Red Belly Blockchain holds blockchain participants accountable for their actions to achieve unprecedented security. Existing blockchains lose assets if a third of the participants experience a problem, which is inevitable after a sufficiently long execution. In reality blockchain participants are generally rational and will try to maximize their profit, sometimes hacking their own copy of their software if it is worth it. Red Belly Blockchain ensures that these participants get detected and punished, hence incentivizing sufficiently many of them to guarantee that no double spending occurs in reality.

No leader for a higher bandwidth

In RedBelly blockchain there is no leader machine that aggregates the transactions and send it to or receives it from other computers, avoiding the bottleneck.

Each RedBelly blockchain computer receives the requested transactions of its neighbors that it exchanges with other computers to aggregate the results.

It solves the Set Byzantine Consensus problem using the Democratic BFT algorithm. Because it does not use any leader, it leverages the bandwidth.
