+https://github.com/Ayms/node-Tor#phases-and-funding + +Quick reminder: this is a javascript implementation of the Tor protocol +inside nodes and browsers + +Phase 4 (evented pipes) has been developped (self funded) but is not +fully tested/released, however the doc is here: +https://github.com/Ayms/node-Tor/blob/master/docs/README.md, it allows +to simply anonymize any protocol piping it to the Tor protocol + +We were about to implement phase 5 (elliptic crypto, Tor v3 features and +WebRTC) but are running out of funding, while we have self funded the +vast majority of this project since 2012 we can't continue (thanks to +NLnet for supporting phases 1 to 3) and are looking for funding to +complete this work (cf above link) + +The timing is supposed to be now because restarting such a project in +months or years is not trivial and despite of the huge efforts for the +refactoring/update/cleaning of the initial code and split into modules +it's probably still difficult to use/integrate/modify (see +https://github.com/Ayms/node-Tor/issues/14), it will become quite easy +if the project goes to its targeted phase + +The code is subtle and minimal, it represents only 1MB browserified not +minified, so 500kB minified, which is quite small for what it does with +zero external dependencies, redevelopping everything from scratch would +be long and difficult + +Some examples of what node-Tor does (as nodes or inside browsers using +WebSockets/WebRTC/XHR): + +http.pipe(parser).pipe(gzip).pipe(tls).pipe(node-Tor) + +ipfs.pipe(node-Tor) + +webtorrent.pipe(node-Tor) + +bitcoin | node-Tor | bitcoin (via stdin/stdout or using IPC) + +Of course the Tor protocol itself might not be enough and each project +might have to design the full anonymization system (peer discovery, +introduction, etc) but they can rely on node-Tor to implement the Tor +protocol (not to be misunderstood again with the Tor network) + +It does implement direct p2p via the Tor protocol or via RendezVous +(RDV) points using also Tor protocol hops to connect to them, the peers +advertise what they have or do using a hash to the RDV points they are +connected to, please see +https://github.com/Ayms/node-Tor#phase-4-and-phase-5 + +Example: by convention a bitcoin node could advertise a hash of "Satoshi +Nakamoto" to tell it is a bitcoin node, then bitcoin nodes will connect +to each others via RDV points or several Tor protocol hops requesting +this hash, they can also connect directly via several hops for well +known bitcoin nodes that don't need to hide themselves but want to hide +to whom they are connected to, which can be wallets too, for example to +hide who originated a transaction + +Since peers are implementing both direct p2p and RDV functions (both via +Tor protocol hops), and can extend to other peers as peers or RDV points +again, it becomes difficult to understand who is doing what and how many +hops finally are used between the peers (suggested setting for p2p is 2 +hops instead of 3 for a Tor protocol circuit, knowing that the number of +hops can extend via RDV points) + +This is the current design and can of course be adapted + +It would look logical that this techno is integrated natively one day +inside browsers, again it must not be misunderstood with what the Tor +Browser is doing (with many specific features inside the browser itself) +and is not a replacement for it, this is different but could be used +also by the Tor network with browsers acting as real Tor nodes (a bit à +la Snowflake but not only relaying messages via WebRTC, implementing the +Tor protocol inside browsers), or uproxy-like for those that remember it + +-- +Move your coins by yourself (browser version): https://peersm.com/wallet
