Mempool.space is an open-source mempool visualizer and blockchain explorer for Bitcoin. It provides real-time updates and live transaction tracking. It is unique in that it was developed to focus on the ephemeral data from the mempool, while most explorers turn up on-chain data.
Flip interviewed the project’s two lead administrators, Simon and Wiz, to dig a little deeper into what makes this one of the best data-centric apps in the Bitcoin ecosystem.
In the interview, we talked about the origin story, some of the technology used and why speed is so important, and heard about some of the necessary improvements. The project’s code is open source under the MIT license and can be found at https://github.com/mempool/mempool.
