Connecting to Mainnet

Join the live QoreChain Vladi mainnet by configuring your node with the official genesis file, peers, and network settings.

note

This page covers the qorechain-vladi mainnet (EVM chain ID 9801, hex 0x2649), live since 7 June 2026 23:59 UTC running chain version v3.1.85 on Cosmos SDK v0.53. For the qorechain-diana testnet (EVM chain ID 9800), see Connecting to Testnet and rehearse your setup there before going live.

Public Endpoints​

If you only need to query the chain or broadcast transactions, you do not need your own node — the public endpoints are:

ServiceURL
Consensus RPChttps://rpc.qore.host (WebSocket: wss://rpc.qore.host/websocket)
Cosmos REST (LCD)https://api.qore.host
EVM JSON-RPChttps://evm.qore.host (chain ID 9801)
SVM JSON-RPC (read-only)https://svm.qore.host
Block explorerexplore.qore.network

For heavy or production workloads (exchanges, indexers), run your own node as described below.

Install​

Install the qorechaind binary either from the official prebuilt bundle or by building from source.

Prebuilt binary bundle (linux/amd64)​

The official release bundle contains qorechaind plus its required shared libraries (libqorepqc.so, libqoresvm.so, libwasmvm.x86_64.so):

curl -fsSL https://download.qore.host/qorechaind-v3.1.83-linux-amd64.tar.gz -o qore.tgz
# Verify the checksum before installing:
sha256sum qore.tgz
# fa035b3699e92d755f47445cbf7dde4e1f6c224343008546aa159b7eb46a805c

tar xzf qore.tgz
sudo install -m0755 qorechaind /usr/local/bin/
sudo mkdir -p /opt/qorechain/lib && sudo cp lib/*.so /opt/qorechain/lib/
export LD_LIBRARY_PATH=/opt/qorechain/lib

Versioned bundles are published at download.qore.host; each release ships with its SHA-256 checksum — always install the latest published bundle.

Keep your node current

Full nodes must track the network's chain version (currently v3.1.85). An outdated node cannot decode newer transaction types (for example, eth_secp256k1-signed transactions introduced in v3.1.83) and will stop syncing once one appears in a block.

Build from source​

git clone https://github.com/qorechain/qorechain-core.git
cd qorechain-core
CGO_ENABLED=1 go build -o qorechaind ./cmd/qorechaind/

See Building from Source for the full prerequisites (Go 1.26+, CGO, Rust toolchain, native libraries).

Initialize the node​

qorechaind init my-node --chain-id qorechain-vladi

This creates the default configuration and data directories under ~/.qorechaind/.

Download Genesis​

Replace your local genesis file with the official mainnet genesis:

curl -fsSL https://download.qore.host/genesis.json -o ~/.qorechaind/config/genesis.json

The same file is also served live by the chain itself — you can cross-verify the download against it:

curl -s https://rpc.qore.host/genesis | jq '.result.genesis' > /tmp/genesis-live.json

This file defines the initial state of the Vladi mainnet, including the genesis validator set, token allocations (TGE at genesis), and module parameters.

Configure Peers​

Edit your node configuration to connect to the public mainnet sentry nodes.

Open ~/.qorechaind/config/config.toml and set the persistent_peers field:

persistent_peers = "0c9b83801ad519671daf19387b6635f72cb9ddd3@44.200.237.4:26656,83cab9ae05d17073c4e45c25d2422b25fff71fe7@35.174.136.254:26656"

Also set the minimum gas price in ~/.qorechaind/config/app.toml (the network fee floor is 0.1uqor):

minimum-gas-prices = "0.1uqor"

You may also want to adjust the following in config.toml:

[mempool]
size = 5000

[consensus]
timeout_propose = "3s"
timeout_commit = "5s"

These values are tuned for the Vladi mainnet's block times and throughput.

Fast Bootstrap (Snapshot)​

Syncing from genesis can take a long time. A fresh chain-data snapshot is published at download.qore.host:

curl -fsSL https://download.qore.host/qore-vladi-snapshot-90833.tar.gz -o snapshot.tar.gz
# Verify before extracting:
sha256sum snapshot.tar.gz
# ebe469796ad96e692877846c7bfd8513d773321c77e415b1358790b7c4e53396

tar xzf snapshot.tar.gz -C ~/.qorechaind/

Snapshots are published under height-stamped filenames — check download.qore.host for the most recent one. Alternatively use state sync — see Running a Node for the full workflow.

Start Node​

Launch your node to begin syncing with the network:

qorechaind start --minimum-gas-prices=0.1uqor

The node connects to peers and begins downloading blocks (from genesis, or from the snapshot height if you restored one).

Check Sync Status​

Verify that your node is catching up to the latest block:

curl localhost:26657/status | jq '.result.sync_info.catching_up'
  • true — The node is still syncing. Wait for it to catch up.
  • false — The node is fully synced and processing new blocks.

You can also check the latest block height:

curl localhost:26657/status | jq '.result.sync_info.latest_block_height'

Confirm you are on the right network — the network field should report qorechain-vladi:

curl localhost:26657/status | jq '.result.node_info.network'

Monitoring​

QoreChain exposes several endpoints for monitoring node health and performance.

Prometheus Metrics​

Raw metrics are available at:

http://localhost:26660/metrics

These metrics can be scraped by any Prometheus-compatible collector.

Grafana Dashboards​

If running via Docker Compose, Grafana is available at:

http://localhost:3001

On first login, set your own credentials when prompted — do not leave the defaults in place. Pre-configured dashboards display block production, transaction throughput, peer connections, and resource usage.

REST Health Check​

The REST API provides a quick status endpoint:

http://localhost:1317
