We are happy to announce testing of Bitcoin Knots v25.1 has completed successfully, and is now deployed to production. Among other improvements, this upgrade fixes this long-standing vulnerability exploited by modern spammers. As a result, our blocks will now include many more real transactions and help to bring an end to the DoS attack being performed on the #Bitcoin network. So, in addition to our already-established benefits (transparency, non-custodial, and permissionless), we now also offer honest miners the first easy option to contribute toward blocks full of real transactions, effectively a several times larger block size in terms of transaction confirmations, without actually making the blocks any larger.
