Velana Testnet validators

The public testnet runs on 8 validators (Besu QBFT) on 4 servers. This page shows, block by block, which validators are taking their turn to propose, so a stopped validator shows up before the chain is at risk.

Loading network health…

Updated every 2 minutes from the public RPC. Status is inferred from blocks (proposers, QBFT rounds and commit seals), not from inside the servers. Test VELA has no monetary value.

QBFT needs a quorum of validators to agree on each block. With 8 validators the quorum is 6, so the chain keeps going with up to 2 validators down. node1 and node2 each run 3 validators, so losing either whole server stops new blocks until it is back. Spreading validators so no server holds more than 2 is on the roadmap.

How to read this

OK
Every validator proposed a block in the last 24 blocks and the newest block is recent.
Degraded
One or more validators have missed their turns. Blocks still arrive while at least 6 of 8 are up.
Halted
No new block for over 2 minutes. When idle the chain makes an empty block every 30 seconds, so this means blocks have stopped.
Round
0 means the expected proposer made the block. A higher round means the expected proposer did not answer in time and another validator took over.
Commit seals
Signatures from validators that agreed to the block. At least 6 are needed.
