XTblock

A permissioned, sharded, EVM-compatible blockchain with a desktop operator console and a developer portal.

Run a delegate, operate a chain from the desktop Console, or just deploy and call contracts from a web page. No delegate access needed for developers.

Sharded EVM

Accounts and contracts live on shards chosen by address hash. A coordinator chain anchors shard checkpoints and records cross-shard (2PC) outcomes.

Wallet compatible

Send legacy (EIP-155) transactions with MetaMask, ethers or web3 through the xtgw gateway. Native token XTT, 18 decimals.

Developer portal

Every gateway serves a web page with wallet, contract deploy and call, block explorer and a test faucet. Deploys align to your shard automatically.

Operator Console

Desktop app to create and monitor instances, build genesis manifests and network maps, run 2PC transfers and browse the chain. A Developer mode hides node management.

Forensics

Search the full transaction history of any address, trace internal contract calls, export signed evidence that can be verified offline, and compare account snapshots. Needs delegates running the history archive.

Explorer

Browse your chains inside the Console: blocks, transactions, address history and cross-shard (2PC) lookups, across every shard.

Fault tolerant

DPoS delegates with suspension and slashing, state sync, automatic fork recovery with backups, and crash-safe state files that survive a power loss.

Atomic cross-shard

Two-phase commit across shards: all legs commit or none are applied.

Download

Releases are published on GitHub. Download the newest Console installer from the latest release. Every delegate of a chain must run the same version (xtcn 0.10.40, bundled).

Start in five minutes

I am a developer

  1. Get the gateway address from your network operator.
  2. Open http://<gateway>:<port>/ in a browser.
  3. Create a wallet, request test XTT from the faucet.
  4. Deploy and call your contract in the Deploy and Call tabs.

I run nodes

  1. Install the Console (it bundles the node and gateway).
  2. Create a delegate instance and start it.
  3. Build a genesis manifest and network map for a multi-delegate chain.
  4. Start the gateway and share its portal address with developers.

Testnet notice

This is a test network. Tokens have no value and the network may be reset. Contracts must be deployed with the developer portal or the Console so the contract address lands on your own shard; use wallets for transfers and calls. See the release notes for known limitations.
