+
+The Onionr software and any nodes you control are within scope.
+
+Avoid social engineering, volume-based denial of service and disrupting or harming the Onionr network. Do not attempt to exploit any machines/servers you do not own or otherwise have permission to do so.
+
+The following exploits are of particular interest:
+
+* Arbitrary code execution
+* API authentication bypass (such as accessing local API from public interface)
+* Deanonymization:
+  * Easily associating public keys with server addresses
+  * Discovering true server IPs when behind Tor/I2P (aside from Tor/i2p-level attacks)
+  * Easily discovering which nodes are the block creator
+* XSS, CSRF, clickjacking, DNS rebinding
+* Timing attacks against the local http server ([see blog post](https://www.chaoswebs.net/blog/timebleed-breaking-privacy-with-a-simple-timing-attack.html))
+* Discovering direct connection servers as a non participant.
+* Cryptography/protocol issues
+* Denying nodes access to the network by segmenting them out with Sybil nodes

+# Onionr Block Spec v1.1.0
+
+# Block Description
+
+Onionr Blocks are the primary means of sharing information in Onionr. Blocks are identified by a single hash value of their entire contents, using SHA3_256.
+
+Blocks contain a JSON metadata section followed by a line break, with the main data section comprising the rest.
+
+In the future, the specification will likely be updated to use flags and MessagePack instead of JSON with english keys.
+
+# Encryption and Signatures
+
+Onionr blocks may be encrypted or signed. In the reference client, this is done with libsodium, for both asymmetric and symmetric encryption.
+
+Unlike many similar projects, blocks may completely be in plaintext, making Onionr suitable for sharing information publicly.
+
+# Metadata Section
+
+The metadata section has the following fields. If a block contains any other field, it must be considered invalid. All metadata fields are technically optional, but many are useful and essentially necessary for most use cases.
+
+## meta
+
+Max byte size: 1000
+
+Meta is a string field which can contain arbitrary sub fields. It is intended for applications and plugins to use it for arbitrary metadata information. In the reference client, if the data section is encrypted or signed, the meta section also is.
+
+Common meta fields, such as 'type' are used by the reference Onionr client to describe the type of a block.
+
+## sig
+
+Max byte size: 200
+
+Sig is a field for storing public key signatures of the block, typically ed25519. In the reference client, this field is a base64 encoded signature of the meta field combined with the block data. (**Therefore, information outside of the meta and data fields cannot be trusted to be placed there by the signer, although it can still be assured that the particular block has not been modified.**)
+
+Note: the max field size is larger than a EdDSA signature (which is what is typically used) in order to allow other primitives for signing in alternative implementations or future versions.
+
+## signer
+
+Max byte size: 200
+
+Signer is a field for specifying the public key which signed the block. In the reference client this is a base64 encoded ed25519 public key.
+
+## time
+
+Max byte size: 10
+
+Time is an integer field for specifying the time of which a block was created. The trustworthiness of this field is based on one's trust of the block creator, however blocks with a time field set in the future (past a reasonable clock skew) are thrown out by the reference client.
+
+## expire
+
+Max byte size: 10
+
+Expire is an integer field for specifying the time of which the block creator has indicated that the block should be deleted. The purpose of this is for voluntarily freeing the burden of unwanted blocks on the Onionr network, rather than security/privacy (since blocks could be trivially kept past expiration). Regardless, the reference client deletes blocks after a preset time if the expire field is either not set or longer than the preset time.
+
+## pow
+
+Max byte size: 1000
+
+Pow is a field for placing the nonce found to make a block meet a target proof of work. In theory, a block could meet a target without a random token in this field.
+
+## encryptType
+
+encryptType is a field to specify the mode of encryption for a block. The values supported by Onionr are 'asym' and 'sym'.

These blocks can be encrypted to a user (or for one's 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.

 Public keys can be generated deterministically 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.

 # Direct Connections
 
-We propose a method of using Onionr's block sync system to enable direct connections between peers by having one peer request to connect to another using the peer's public key. Since the request is within a standard block, proof of work must be used to request connection. If the requested peer is available and wishes to accept the connection, Onionr will generate a temporary .onion address for the other peer to connect to. Alternatively, a reverse connection may be formed, which is faster to establish but requires a message brokering system instead of a standard socket.

+The files in this submodule handle various subtasks and utilities for the onionr communicator.
+
+## Files:
+
+announcenode.py: Uses a communicator instance to announce our transport address to connected nodes
+
+connectnewpeers.py: takes a communicator instance and has it connect to as many peers as needed, and/or to a new specified peer.
+
+cooldownpeer.py: randomly selects a connected peer in a communicator and disconnects them for the purpose of security and network balancing.
+
+daemonqueuehandler.py: checks for new commands in the daemon queue and processes them accordingly.
+
+deniableinserts.py: insert fake blocks with the communicator for plausible deniability
+
+downloadblocks.py: iterates a communicator instance's block download queue and attempts to download the blocks from online peers
+
+housekeeping.py: cleans old blocks and forward secrecy keys
+
+lookupadders.py: ask connected peers to share their list of peer transport addresses
+
+lookupblocks.py: lookup new blocks from connected peers from the communicator
+
+netcheck.py: check if the node is online based on communicator status and onion server ping results
+
+onionrcommunicataortimers.py: create a timer for a function to be launched on an interval. Control how many possible instances of a timer may be running a function at once and control if the timer should be ran in a thread or not.
+
+proxypicker.py: returns a string name for the appropriate proxy to be used with a particular peer transport address.
+
+servicecreator.py: iterate connection blocks and create new direct connection servers for them.
+
+uploadblocks.py: iterate a communicator's upload queue and upload the blocks to connected peers

-A. HISTORY OF THE SOFTWARE
-==========================
-
-Python was created in the early 1990s by Guido van Rossum at Stichting
-Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
-as a successor of a language called ABC.  Guido remains Python's
-principal author, although it includes many contributions from others.
-
-In 1995, Guido continued his work on Python at the Corporation for
-National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
-in Reston, Virginia where he released several versions of the
-software.
-
-In May 2000, Guido and the Python core development team moved to
-BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
-year, the PythonLabs team moved to Digital Creations, which became
-Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
-https://www.python.org/psf/) was formed, a non-profit organization
-created specifically to own Python-related Intellectual Property.
-Zope Corporation was a sponsoring member of the PSF.
-
-All Python releases are Open Source (see http://www.opensource.org for
-the Open Source Definition).  Historically, most, but not all, Python
-releases have also been GPL-compatible; the table below summarizes
-the various releases.
-
-    Release         Derived     Year        Owner       GPL-

-Footnotes:
-
-(1) GPL-compatible doesn't mean that we're distributing Python under
-    the GPL.  All Python licenses, unlike the GPL, let you distribute
-    a modified version without making your changes open source.  The
-    GPL-compatible licenses make it possible to combine Python with
-    other software that is released under the GPL; the others don't.
-
-(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
-    because its license has a choice of law clause.  According to
-    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
-    is "not incompatible" with the GPL.
-
-Thanks to the many outside volunteers who have worked under Guido's
-direction to make these releases possible.
