🐛 Bitcoin Core developers fix bug that could have crashed the network

Node operators have been asked to upgrade their software immediately following the discovery of a bug that could have crashed the Bitcoin ($BTC) and derivative networks like Bitcoin Cash ($BCH) and Litecoin ($LTC). The issue was related to a change made to the code in late 2016 aimed at reducing the time to check blocks. In theory had the issue not been fixed a miner could have designed a block which would have crashed other mining nodes on the network.
