-# 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.

+
+# Introduction
+
+The most important thing in the modern world is information. The ability to communicate freely with others. The internet has provided humanity with the ability to spread information globally, but there are many people who try (and sometimes succeed) to stifle the flow of information.
+
+Internet censorship comes in many forms, state censorship, corporate consolidation of media, threats of violence, network exploitation (e.g. denial of service attacks).
+
+To prevent censorship or loss of information, these measures must be in place:
+
+* Resistance to censorship of underlying infrastructure or of network hosts
+
+* Anonymization of users by default
+   * The Inability to violently coerce human users (personal threats/"doxxing", or totalitarian regime censorship)
+
+* Economic availability. A system should not rely on a single device to be constantly online, and should not be overly expensive to use. The majority of people in the world own cell phones, but comparatively few own personal computers, particularly in developing countries.
+
+There are many great projects that tackle decentralization and privacy issues, but there are none which tackle all of the above issues. Some of the existing networks have also not worked well in practice, or are more complicated than they need to be.
+
+# Onionr Design Goals
+
+When designing Onionr we had these goals in mind:
+
+* Anonymous Blocks
+
+ * Difficult to determine block creator or users regardless of transport used
+* Default Anonymous Transport Layer
+ * Tor and I2P
+* Transport agnosticism
+* Default global sync, but can configure what blocks to seed
+* Spam resistance
+* Encrypted blocks
+
+# Onionr Design
+
+(See the spec for specific details)
+
+## General Overview
+
+At its core, Onionr is merely a description for storing data in self-verifying packages ("blocks"). These blocks can be encrypted to a user (or self), encrypted symmetrically, or not at all. Blocks can be signed by their creator, but regardless, they are self-verifying due to being identified by a sha3-256 hash value; once a block is created, it cannot be modified.
+
+Onionr exchanges a list of blocks between all nodes. By default, all nodes download and share all other blocks, however this is configurable.
+
+## User IDs
+
+User IDs are simply Ed25519 public keys. They are represented in Base32 format, or encoded using the [PGP Word List](https://en.wikipedia.org/wiki/PGP_word_list).
+
+Public keys can be generated deterministicly with a password using a key derivation function (Argon2id). This password can be shared between many users in order to share data anonymously among a group, using only 1 password. This is useful in some cases, but is risky, as if one user causes the key to be compromised and does not notify the group or revoke the key, there is no way to know.
+
+## Nodes
+
+Although Onionr is transport agnostic, the only supported transports in the reference implemetation are Tor .onion services and I2P hidden services. Nodes announce their address on creation.
+
+### Node Profiling
+
+To mitigate maliciously slow or unreliable nodes, Onionr builds a profile on nodes it connects to. Nodes are assigned a score, which raises based on the amount of successful block transfers, speed, and reliabilty of a node, and reduces based on how unreliable a node is. If a node is unreachable for over 24 hours after contact, it is forgotten. Onionr can also prioritize connection to 'friend' nodes.
+
+## Block Format
+
+Onionr blocks are very simple. They are structured in two main parts: a metadata section and a data section, with a line feed delimiting where metadata ends and data begins. 
+
+Metadata defines what kind of data is in a block, signature data, encryption settings, and other arbitrary information.
+
+Optionally, a random token can be inserted into the metadata for use in Proof of Work.
+
+### Block Encryption
+
+For encryption, Onionr uses ephemeral Curve25519 keys for key exchange and XSalsa20-Poly1305 as a symmetric cipher, or optionally using only XSalsa20-Poly1305 with a pre-shared key.
+
+Regardless of encryption, blocks can be signed internally using Ed25519.
+
+## Block Exchange
+
+Blocks can be exchanged using any method, as they are not reliant on any other blocks.
+
+By default, every node shares a list of the blocks it is sharing, and will download any blocks it does not yet have.
+
+## Spam mitigation and block storage time
+
+By default, an Onionr node adjusts the target difficulty for blocks to be accepted based on the percent of disk usage allocated to Onionr.
+
+Blocks are stored indefinitely until the allocated space is filled, at which point Onionr will remove the oldest blocks as needed, save for "pinned" blocks, which are permanently stored.
+
+## Block Timestamping
+
+Onionr can provide evidence of when a block was inserted by requesting other users to sign a hash of the current time with the block data hash: sha3_256(time + sha3_256(block data)).
+
+This can be done either by the creator of the block prior to generation, or by any node after insertion.
+
+In addition, randomness beacons such as the one operated by [NIST](https://beacon.nist.gov/home) or the hash of the latest blocks in a cryptocurrency network could be used to affirm that a block was at least not *created* before a given time.

+# Onionr UI
+
+## About
+
+The default GUI for Onionr
+
+## Setup
+
+To compile the application, simply execute the following:
+
+```
+python3 compile.py
+```
+
+If you are wanting to compile Onionr UI for another language, execute the following, replacing `[lang]` with the target language (supported languages include `eng` for English, `spa` para español, and `zho`为中国人):
+
+```
+python3 compile.py [lang]
+```
+
+## FAQ
+### Why "compile" anyway?
+This web application is compiled for a few reasons:
+1. To make it easier to update; this way, we do not have to update the header in every file if we want to change something about it.
+2. To make the application smaller in size; there is less duplicated code when the code like the header and footer can be stored in an individual file rather than every file.
+3. For multi-language support; with the Python "tags" feature, we can reference strings by variable name, and based on a language file, they can be dynamically inserted into the page on compilation.
+4. For compile-time customizations.
+
+### What exactly happens when you compile?
+Upon compilation, files from the `src/` directory will be copied to `dist/` directory, header and footers will be injected in the proper places, and Python "tags" will be interpreted.
+
+
+### How do Python "tags" work?
+There are two types of Python "tags":
+1. Logic tags (`<$ logic $>`): These tags allow you to perform logic at compile time. Example: `<$ import datetime; lastUpdate = datetime.datetime.now() $>`: This gets the current time while compiling, then stores it in `lastUpdate`.
+2. Data tags (`<$= data $>`): These tags take whatever the return value of the statement in the tags is, and write it directly to the page. Example: `<$= 'This application was compiled at %s.' % lastUpdate $>`: This will write the message in the string in the tags to the page.
+
+**Note:** Logic tags take a higher priority and will always be interpreted first.
+
+### How does the language feature work?
+When you use a data tag to write a string to the page (e.g. `<$= LANG.HELLO_WORLD $>`), the language feature simply takes dictionary of the language that is currently being used from the language map file (`lang.json`), then searches for the key (being the variable name after the characters `LANG.` in the data tag, like `HELLO_WORLD` from the example before). It then writes that string to the page. Language variables are always prefixed with `LANG.` and should always be uppercase (as they are a constant).
+
+### I changed a few things in the application and tried to view the updates in my browser, but nothing changed!
+You most likely forgot to compile. Try running `python3 compile.py` and check again. If you are still having issues, [open up an issue](https://gitlab.com/beardog/Onionr/issues/new?issue[title]=Onionr UI not updating after compiling).
