API Documentation

Comprehensive API specification is available.

The manual describes API endpoints to manage accounts, transactions, chats, and a key-value storage (KVS). Additionally, the manual suggests valuable information on creating new accounts and encrypting and decrypting messages.

Set up

How to run ADAMANT node (instructions for users). You can skip them if you are experienced Linux user.

Requirements

  • Ubuntu 18/20 (others are not tested)
  • 2 GB RAM
  • 50 GB disk space as on August 2021

Installation script

For new droplets, use the Installation script, included in this repository, or run it from the ADAMANT website:

sudo bash -c "$(wget -O - https://adamant.im/install_node.sh)"

The script updates Ubuntu packages, creates user named adamant, installs PostgreSQL, Node.js and other necessary packages, sets up ADAMANT node, and optionally downloads up-to-date ADAMANT blockchain image.

Script parameters:

  • -b
    : choose GitHub branch for node installation. Example:
    -b dev
    . Default is
    master
    .
  • -n
    : choose
    mainnet
    or
    testnet
    network. Example:
    -n testnet
    . Default is
    mainnet
    .

F. e.,

sudo bash -c "$(wget -O - https://adamant.im/install_node.sh)" -O -b dev -n testnet

Prerequisites

  • Tool chain components — Used for compiling dependencies

sudo apt-get install -y python build-essential curl automake autoconf libtool
  • Git — Used for cloning and updating ADAMANT

sudo apt-get install -y git
  • Node.js — Node.js serves as the underlying engine for code execution

System wide via package manager:

  curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
  sudo apt-get install -y nodejs

Locally using nvm:

  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
  nvm i --lts=fermium
  • Install PostgreSQL:
  sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
  wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -
  sudo apt-get update
  sudo apt-get install -y postgresql postgresql-contrib libpq-dev

Create user if you are working from superuser

adduser adamant sudo usermod -aG sudo adamant su - adamant

Create db

sudo -u postgres createuser --createdb $USER createdb adamant_test createdb adamant_main sudo -u postgres psql -d adamant_test -c "alter user "$USER" with password 'password';" sudo -u postgres psql -d adamant_main -c "alter user "$USER" with password 'password';"

  • pm2 — Manages the node process for ADAMANT

sudo npm install -g pm2

Installation Steps

Clone the ADAMANT repository using Git and initialize the modules.

git clone https://github.com/Adamant-im/adamant
cd adamant
npm install

Then set db.password in config:

nano config.json

Bootstrap with a blockchain image

Blockchain image saves time on node sync but you must completely trust the image. If you skip this step, your node will check every single transaction, which takes time (up for several days).

wget https://explorer.adamant.im/db_backup.sql.gz
gunzip db_backup.sql.gz
psql adamant_main < db_backup.sql
rm db_backup.sql

Managing ADAMANT

To test that ADAMANT is built and configured correctly, run the following command:

node app.js

Once the process is verified as running correctly,

CTRL+C
and start the process with
pm2
. This will fork the process into the background and automatically recover the process if it fails.

pm2 start --name adamant app.js

After the process is started, its runtime status and log location can be retrieved by issuing the following command:

pm2 show adamant

To stop ADAMANT after it has been started with

pm2
, issue the following command:

pm2 stop adamant

To add ADAMANT node to crontab for autostart after system reboot (fix installation path):

crontab -l | { cat; echo "@reboot cd /home/adamant/adamant && pm2 start --name adamant app.js"; } | crontab -

Tests

Before running any tests, run ADAMANT node with a testnet configuration:

npm run start:testnet

Then run the test suite:

npm run test:full

Run individual tests:

npm run test:single test/api/accounts.js
