AT2

Asset Transfer System using lightweight broadcast-based primitives instead of consensus

We replace consensus with a lightweight building block -- a broadcast-based primitive -- to obtain a full-fledged asset transfer system (cryptocurrency). This system is more efficient and more scalable compared with Bitcoin and consensus-based solutions. AT2 is the first system to bypass consensus algorithms for implementing asset transfers.

In this specific case of asset transfer, one doesn't need a "full-blockchain", only some simpler primitives. Here comes AT2, which allows for the same capabilities as Bitcoin while being orders of magnitudes faster, around 10'000 TPS. By avoiding the classical proof-of-work used in other blockchains, it also greatly reduces the total energy consumption.

In the demonstrator, you will be able to create your own account on the AT2 chain, that we graciously fill up with an initial number of assets. You can then send assets to some other previously registered user. You will also be performing a speedtest to measure how many transactions the system can hold. The main AT2 network is currently run at EPFL by some labs and interested users.
