I’m running a pruned full node of bitcoin core version 0.14.0 and checking on https://bitnodes.21.co/nodes/ I can see that my node was labelled “NODE_WITNESS (12)” unlike of the others nodes shown, which was labelled “NODE_WITNESS (13)”.
I’ve looked through several pages on bitnodes to find some more nodes that show
NODE_WITNESS (12). I’ve noticed a pattern: the number corresponds to the services that a node offers. Nodes advertise the services that they offer by sending a bitmap named
nServices. The number in the brackets matches the decimal representation of the service bits that a node has set.
Looking around a bit, I’ve identified the following five bits:
So, I’d say that with (12), you must be offering the services
NODE_BLOOM, NODE_WITNESS (12), lemme guess, you run a pruning node? 🙂 Or would it be “blocksonly”?
Edit: Here are the service bits defined in the source code:
