Archethic

Welcome to the Archethic Node source repository ! This software enables you to build the first transaction chain and next generation of blockchain focused on scalability and human oriented.

Archethic features:

• Fast transaction processing (> 1M tps)
• Lower energy consumption than other blockchain
• Designed with a high level of security (ARCH consensus supporting 90% of maliciousness)
• Adaptive cryptographic algorithms (quantum resistant)
• Decentralized Identity and Self Sovereign Identity
• Smart contract platform powered by a built-in interpreter
• Strong scalability with geo secured sharding
• Soft-Real-Time P2P view with supervised networking

Development

Our codebase aims to reach the guidelines of Elixir projects. We are focusing on the best quality.

The source code can change to respect the best quality of reading and regarding best practices.

Current implemented features:

• Adaptive cryptography: different elliptic curves and software implementation
• Hybrid root of trust: mix of hardware and software cryptographic key to maintain trust and security
• TransactionChain: Transaction structure and transaction generation
• Smart Contract: interpreter coded with Elixir DSL through Meta-programming and AST
• Node election: heuristic validation and storage node selection
• P2P: Inter-node communication, supervised connection to detect the P2P view of nodes in almost real-time
• Transaction mining: ARCH consensus
• Beacon chain: Maintains a global view of the network (transactions, P2P view)
• Self-Repair: Self-healing mechanism allowing to resynchronize missing transactions
• Embedded explorer leveraging sharding to retrieve information
• Custom Binary protocol for data transmission
• Token minting
• Internal oracles (UCO Price Feed)
• Tailored embedded database

Running a node for development purpose

Using Elixir

Requirements:

• Libsodium: for the ed25519 to Curve25519 conversion
• OpenSSL 1.11
• Erlang OTP 25
• Elixir 1.14
• GMP (https://gmplib.org/)
• MiniUPnP used for port forwarding & IP lookup (https://miniupnp.tuxfamily.org/)
• Npm for static assets (https://nodejs.org/en/download)

Platforms supported:

• Linux (Ubuntu 18.04)
• Mac OS X

At first, clone the repository:

git clone https://github.com/archethic-foundation/archethic-node.git
cd archethic-node

Get dependencies:

mix deps.get

Install the static assets

cd assets ; npm install; cd -

To start a single node:

iex -S mix

To clean the data

make clean

To start mutiple node, you need to update some environment variables:

# Start the first node
iex -S mix

# Start second node
ARCHETHIC_CRYPTO_SEED=node2 ARCHETHIC_P2P_PORT=3003 ARCHETHIC_HTTP_PORT=4001 ARCHETHIC_HTTPS_PORT=5001 iex -S mix

# To start other node, increment the environment variables

Using docker

Requires docker compose plugin

At first, clone the repository:

git clone https://github.com/archethic-foundation/archethic-node.git
cd archethic-node

Build the image:

docker build -t archethic-node .

To start a single node:

# You can run node up to node3
docker compose up node1
docker compose up node2
docker compose up node3

To start all nodes at the same time:

docker compose up

To run benchmarks:

docker compose up bench

To run the playbooks to validate non regression:

docker compose up validate

Using snap

Work in progress ..

Running a node for testnet / mainnet

Will be opened regarding roadmap advancement
