 One of the main results we have obtained concerns decentralized payments, or the **asset transfers** problem.
-All current solutions for solving this problem rely on a consensus algorithm, which is a very expensive building block.
+Bitcoin is one of the most popular solution to this problem.
+Like all current solutions, Bitcoin relies on a consensus algorithm, which is a very expensive building block.
+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 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
+This result highlights the importance of studying distributed systems from first principles. We are currently working on several AT2 implementations.
