-# Onionr Protocol Spec v2
-
-A P2P platform for Tor & I2P
-
-# Overview
-
-Onionr is an encrypted microblogging & mailing system designed in the spirit of Twitter.
-There are no central servers and all traffic is peer to peer by default (routed via Tor or I2P).
-User IDs are simply Tor onion service/I2P host id + Ed25519 key fingerprint.
-Private blocks are only able to be read by the intended peer.
-All traffic is over Tor/I2P, connecting only to Tor onion and I2P hidden services.
-
-## Goals:
-    • Selective sharing of information
-    • Secure & semi-anonymous direct messaging
-    • Forward secrecy
-    • Defense in depth
-    • Data should be secure for years to come
-    • Decentralization
-    * Avoid browser-based exploits that plague similar software
-    * Avoid timing attacks & unexpected metadata leaks
-
-## Protocol
-
-Onionr nodes use HTTP (over Tor/I2P) to exchange keys, metadata, and blocks. Blocks are identified by their sha3_256 hash. Nodes sync a table of blocks hashes and attempt to download blocks they do not yet have from random peers.
-
-Blocks may be encrypted using Curve25519 or Salsa20.
-
-Blocks have IDs in the following format:
-
--Optional hash of public key of publisher (base64)-optional signature (non-optional if publisher is specified) (Base64)-block type-block hash(sha3-256)
-
-pubkeyHash-signature-type-hash
-
-## Connections
-
-When a node first comes online, it attempts to bootstrap using a default list provided by a client.
-When two peers connect, they exchange Ed25519 keys (if applicable) then Salsa20 keys.
-
-Salsa20 keys are regenerated either every X many communications with a peer or every X minutes. 
-
-Every 100kb or every 2 hours is a recommended default.
-
-All valid requests with HMAC should be recorded until used HMAC's expiry to prevent replay attacks.
-Peer Types
-    * Friends:
-        * Encrypted ‘friends only’ posts to one another
-        * Usually less strict rate & storage limits
-    * Strangers:
-        * Used for storage of encrypted or public information
-        * Can only read public posts
-        * Usually stricter rate & storage limits
-
-## Spam mitigation
-
-To send or receive data, a node can optionally request that the other node generate a hash that when in hexadecimal representation contains a random string at a random location in the string. Clients will configure what difficulty to request, and what difficulty is acceptable for themselves to perform. Difficulty should correlate with recent network & disk usage and data size. Friends can be configured to have less strict (to non existent) limits, separately from strangers. (proof of work).
-Rate limits can be strict, as Onionr is not intended to be an instant messaging application.
