This reflects both in the poor performance of the Bitcoin platform as well as in its high energy costs. | This reflects both in the poor performance of the Bitcoin platform as well as in its high energy costs. | ||
We showed that this building block is unnecessary, namely that implementing decentralized asset transfers does not require consensus. | We showed that this building block is unnecessary, namely that implementing decentralized asset transfers does not require consensus. | ||

We introduce AT2 (**Asynchronous Trustworthy Transfers**), a class of algorithms for solving asset transfers in various models (shared memory, as well as in the deterministic & probabilistic message-passing models). | We introduce AT2 (**Asynchronous Trustworthy Transfers**), a class of algorithms for solving asset transfers in various models (shared memory, as well as in the deterministic & probabilistic message-passing models). | ||
This result highlights the importance of studying distributed systems from first principles. We are currently working on several AT2 implementations. | This result highlights the importance of studying distributed systems from first principles.
