Smaller Testnet Blocks
Currently bitcoin’s testnet mining is done by mining the entire mempool in every block, this can be relatively annoying to anyone doing development that depends on a fee market like fee adjusting or transaction merging. Recently a developer called on the bitcoin-dev mailing list for the maxBlockWeight of Bitcoin’s testnet to be changed to something less than the entire mempool to help wallet developers in testing. This is a reasonable suggestion as some mainnet wallets have to deal with fee-related problems like stuck transactions and fee bumping. The suggestion is very early but looks promising, we’ll be watching the mailing list for any new updates.
