Shows the number of reachable A node is considered reachable when a connection to it could be established. Bitcoin nodes that provide a particular network service.
Description of network services:
- Network nodes are capable of serving the entire block chain
- Limited Network nodes can serve data from the last 288 blocks, i.e., roughly two days worth of block chain data (cf. signaling part of BIP159). Since (non-limited) network nodes can by definition serve data from the last 288 blocks, this category includes network nodes.
- Bloom Filter nodes can handle bloom-filtered connections (cf. BIP37)
- Witness nodes can be queried for blocks and transactions including witness data (cf. BIP141)
- Compact Filter nodes are capable of handling block filter requests (cf. BIP157 and BIP158)
- V2 Transport nodes support encrypted P2P connections, P2P bandwidth improvements and the ability to negotiate upgrades (cf. BIP324)
