ADAMANT is a decentralized, blockchain-based messaging platform. Applications use ADAMANT as an anonymous, encrypted relay and storage layer for secure communication. Examples include the Messenger app, Blockchain 2FA, and Exchange bot.
For more information, refer to the ADAMANT website:

Additional information:
Comprehensive node documentation is available.
It covers the Fair dPoS consensus algorithm, decentralization principles, node installation and configuration, and other core concepts. The documentation also describes API endpoints for managing accounts, transactions, chats, and key-value storage (KVS), along with account creation, message encryption and decryption, and API data types.

ADAMANT Node requires Node.js 22.13.0 or newer. The installation scripts support Node.js 22, 24, and 26, with Node.js 24 selected by default.
Refer to the ADAMANT Node installation documentation for hardware requirements and complete setup instructions for Linux, macOS, and Windows.
The bundled installers support:
- Ubuntu 20.04, 22.04, 24.04, and 26.04 LTS:
tools/install_node.sh - RHEL-compatible releases 8-10, including CentOS Stream, Rocky Linux, AlmaLinux, and RHEL:
tools/install_node_centos.sh
Ubuntu 20.04 is supported by the script, but its standard security maintenance has ended. Use Ubuntu Pro or upgrade the operating system for continued security updates.
Run an installer as root from the official download URL and select the network, Git branch, and Node.js major version as needed:
sudo bash -c "$(wget -O - https://adamant.im/install_node.sh)" -O -b dev -n mainnet -j 24
sudo bash -c "$(wget -O - https://adamant.im/install_node_centos.sh)" -O -b dev -n mainnet -j 24Both installers update system packages, preserve existing ADAMANT configuration files and local Git changes, and reuse existing users and databases. A blockchain image is skipped when the selected database already contains tables. Installation logs are written to /var/log/adamant_<network>_install.log.
To replace an Ubuntu node database with a newly downloaded blockchain image, use:
sudo bash tools/fix_node.sh -n mainnetThe repair tool drops the database to free disk space, downloads and validates the replacement image, then recreates the database and restores it from the snapshot. Back up any required data first. Repair logs are written to /var/log/adamant_<network>_fix.log.
Always stop the node gracefully. When running it in the foreground, press Ctrl+C and wait for cleanup to finish. Do not use kill -9, forced terminal termination, or any other uncatchable process kill unless the process is already unrecoverably stuck.
The node stores derived consensus state in memory mirror tables such as mem_accounts and mem_round. A forced kill can interrupt block, transaction, or round writes and leave those tables inconsistent with the persisted blockchain. On the next startup this may force a full memory-state rebuild from the beginning of the chain:
[WRN] loader Detected unapplied rounds in mem_round
[WRN] loader Recreating memory tables
[inf] loader Rebuilding blockchain, current block height: 1
If this happens, do not try to repair mem_* tables with manual SQL edits. The reliable recovery options are restoring a trusted database snapshot or letting the node rebuild/replay derived state from the blockchain.
