The battle of Bitcoin developers' 'OP_RETURN' continues to escalate. Bitcoin Core developers refer to the opposition as 'Knotzis' and mock their software vulnerabilities; however, the number of Knots nodes has increased from less than 400 to nearly 4,000 this year, while Core nodes have stagnated at around 20,000. The debate has evolved from technical disagreements to personal attacks, and Chaincode Labs has also been accused of playing a leading role in this. (Protos)
