Kaspa (KAS)

A directed graph instead of a single chain: Kaspa runs the GHOSTDAG protocol, where blocks found in parallel are ordered rather than discarded, which allows a very short block interval without giving up proof of work. The launch had no premine and no founder allocation. Among miners the project is known as an attempt to speed up the Bitcoin-style model while keeping its foundation, and the node software was later rewritten in Rust for performance.
