Arweave Server

This is the repository for the official Erlang implementation of the Arweave protocol and a gateway implementation.

Arweave is a distributed, cryptographically verified permanent archive built on a cryptocurrency that aims to, for the first time, provide feasible data permanence. By leveraging our novel Blockweave datastructure, data is stored in a decentralised, peer-to-peer manner where miners are incentivised to store rare data.

Getting Started

Download and extract the latest archive for your platform on the release page, then run the included bin/start script to get started.

For more information, refer to the mining guide.

Building from source

Requirements

• Erlang OTP v23+, with OpenSSL support
• GCC or Clang
• GNU Make
• CMake (CMake version > 3.10.0)
• SQLite3 headers (libsqlite3-dev on Ubuntu)
• GNU MP (libgmp-dev on Ubuntu)

$ git clone --recursive https://github.com/ArweaveTeam/arweave.git
$ cd arweave
$ ./rebar3 as prod tar

You will then find the gzipped tarball at _build/prod/rel/arweave/arweave-x.y.z.tar.gz.

Contributing

Make sure to have the build requirements installed.

Clone the repo and initialize the Git submodules:

$ git clone --recursive https://github.com/ArweaveTeam/arweave.git

Running a node locally

$ bin/start-dev

Running the tests

$ bin/test

Running a shell

$ bin/shell

bin/test and bin/shell launch two connected Erlang VMs in distributed mode. The master VM runs an HTTP server on the port 1984. The slave VM uses the port 1983. The data folders are data_test_master and data_test_slave respectively. The tests that do not depend on two VMs are run against the master VM.

See CONTRIBUTING.md for more information.

Arweave Bug Bounty Program

Arweave core team has initiated an Arweave bug bounty program, with a maximum bounty of up to USD 1,000,000. The program is focused on discovering potential technical vulnerabilities and strengthening Arweave core protocol security.

The Arweave core team puts security as its top priority and has dedicated resources to ensure high incentives to attract the community at large to evaluate and safeguard the ecosystem. Whilst building Arweave, the team has engaged with industry-leading cybersecurity audit firms specializing in Blockchain Security to help secure the codebase of Arweave protocol.

We encourage developers, whitehat hackers to participate, evaluate the code base and hunt for bugs, especially on issues that could potentially put users’ funds or data at risk. In exchange for a responsibly disclosed bug, the bug bounty program will reward up to USD 1,000,000 (paid in $AR tokens) based on the vulnerability severity level, at the discretion of the Arweave team. Please email us at team@arweave.org to get in touch.
