We’re working on major improvements to The Mempool Open Source Project as part of our upcoming v3.0 release. Here are some of them, which are already live on mempool.space --- 1/ We’ve re-implemented our block template algorithm in Rust for improved accuracy and performance. Before: After: --- 2/ We’ve begun visualizing both `mempoolfullrbf=0` and `mempoolfullrbf=1` transactions together on our RBF timeline. --- 3/ We’ve forked blockstream/electrs to mempool/electrs and made many fixes and improvements. (it's a breaking change -- mempool/mempool 3.x will require mempool/electrs 3.x)
