No Fork, No Fire: Segwit2x Nodes Stall Running Abandoned Bitcoin Code

The Segwit2x bitcoin fork may have been formally called off, but as many as 150 nodes still running its code have stopped accepting transaction blocks.

Data from Bitnodes shows that 95 nodes are currently running 2x software and are stuck at block number 494,782. CoinDance, another network data site, says that 154 nodes are running the “btc1” software as of press time.

The situation is a curious one, given that the 2x fork effort – advanced by a group of startups, miners and community supporters as a way to expand the transaction capacity of the bitcoin network – was effectively disbanded on Nov. 8 following an email circulated on the project’s mailing list. Yet despite the abandonment, dozens of nodes continue to be operated that use the most-recent btc1 software release.

Today’s stoppage appears to be driven by an issue in the code that prevented miners from actually producing a larger-than-1 MB block that would push nodes running Segwit2x into its own chain. Amid growing discussion in the project’s Slack channel, developer Jeff Garzik released a patch aimed at easing the creation of a bigger transaction block (though in the absence of strong mining support, it’s unlikely that the network will advance)…
