Run a Tavchain Testnet full node directly on Linux or Windows. Download one bundle with the client, required libraries and testnet configuration included. You do not need a wallet or stake. For wallet or application access, use public RPC.

Download

Choose your platform from the GitHub release. Before running anything, follow Verify the download to check the release signature and your bundle’s checksum. Use an ordinary user account, persistent SSD storage, reliable outbound internet and accurate system time. Keep RPC private and leave ports 29656, 29657, 29645 and 29646 free. Disk usage grows with chain history.

Initialize and start

Extract the bundle into a new folder and open a terminal in that folder. Keep all extracted files together.
Initialize once, then start:
Initialization creates private node identities and stores node data in .tavchain-testnet-771002 under your user directory. It refuses an existing home instead of overwriting it. If initialization fails, retain the partial directory and see Troubleshooting. Keep the terminal open while the node runs. The included configuration selects native chain tavchaintestnet_771002-1 and EVM chain 771002, connects outbound to public peers and keeps RPC on loopback.

Check synchronization

Open http://127.0.0.1:29657/status in a browser. Check that node_info.network is tavchaintestnet_771002-1, block height advances and sync_info.catching_up becomes false. Zero voting power is normal for a full node. Initial sync replays history and can take time. For peer checks, local EVM RPC and reference-block comparisons, see Monitor a node.

Stop and restart

Interrupt the node in its terminal and wait for shutdown before closing the window. Do not use Task Manager as the normal Windows shutdown procedure. Restart with the same start command and home. Do not initialize again, replace genesis, delete data or run two processes against one home. Custom absolute home paths are supported; see ./tavchain-node --help on Linux or .\tavchain-node.ps1 help on Windows and supply the same home on every invocation.

Compatibility

The bundle uses client 1.8.1-tavchain.eval1-native1. Non-validator initialization, sync, fixed-height state comparison and same-identity restart were tested on GitHub-hosted Ubuntu 24.04 x64/ARM64 and Windows Server 2022 x64. Linux graceful termination used SIGTERM; Windows used the console Ctrl+Break event. Windows browser-download file-blocking behavior was not part of that trial. These tests do not establish validator signing or long-duration reliability. Native macOS and Windows ARM64 bundles are unavailable. Test TAV has no monetary value. For background Linux x86-64 operation, use the Docker guide. The systemd guide covers a separate earlier client installation; do not mix its paths with this bundle. Find source and release authentication files on GitHub. The earlier native client release remains available. For configuration and ports, see Network files and ports.
