undefinedTor-enabled Bitcoin (BTC) nodes come back to normal after almost a full-swing crash in early January 2021, as per the latest data from node monitoring resource Bitnodes. As of Jan. 13, the number of reachable Tor-based BTC nodes totaled 2,581, an incredible increasing trend from 122 nodes on Jan. 9.

Bitnodes data shows Tor-enabled Bitcoin nodes become an essential part of the Bitcoin network, normally accounting for roughly 25% of totally reachable running nodes. More than 23% of total BTC nodes on Jan. 13 were made from Tor-based nodes, as per the latest recorded data. 

Bitnodes notes that the number of Bitcoin nodes now reaches 11,190 nodes, surging from roughly 8,300 on Jan. 7.

A Bitcoin node refers to a computer that is connected to other computers to host and synchronize a copy of the entire Bitcoin blockchain and naturally maintain the running of the entire network. Tor-based Bitcoin nodes mean a kind of node implemented in a private manner through the Tor anonymous network. 

It seems that the latest dip in Tor-enabled BTC nodes can be attributed to a recent crash on the Tor network. Jan. 10 saw Tor Project officially claimed that the Tor network was experiencing instability as a result of an implementation bug in its v3 onion service. The outrage was possible due to a hack attack, according to TechNadu, a tech-centered news agency. 

Afterward, the downtimes in the Tor network exerted an impact on various Tor-enabled or so-called "onion" websites, covering private Bitcoin wallets and exchanges such as Wasabi and Bisq. Jan. 11 witnessed it managed to keep its services intact via a fallback system, Wasabi reported, "If the Tor onion service of the backend becomes unavailable for the user, the wallet falls back to communicating with the backend's clearnet endpoint, still over Tor."
