Bitcoin Unlimited’s network of nodes took a viral hit today.
Nearly 70% of nodes running Bitcoin Unlimited went offline today as word emerged of a bug in the software’s code.
The bug opened a vulnerability through which a certain kind of message sent to nodes could cause them to be taken offline.
Nodes are responsible for validating the transactions on a blockchain, maintaining a copy of the transaction history’s entire record and essentially enforcing the rules of the network through the code.
That discussion – and highlighting of the bug – was followed by an apparent exploit that sent the node count plunging.
To get a sense of the scale, roughly 6,100 nodes make up the bitcoin network’s global ecosystem, according to Bitnodes.
