| + | 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 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). | ||
