Room to grow ×500 at today's load — before a single upgrade.
Celenium /v1/block/stats
Every block now carries 128 MB — 16× bigger after the Matcha upgrade.
Celestia's validators already tested 1 Tb/s of blockspace.
Held 99.97% reliability under a 100 GiB/day, 4-day load test.
A phone verifies a full 128 MB block is really available by pulling just ~16 tiny random samples — no full download, no trusted party. If every sample comes back, the whole block is provably available with ~99% confidence.

Today on Celestia
Read and written by Orion AI · ---
Every number is computed from Celestia's own chain — block headers, namespace blobs, validator set, gas metrics. Nothing is estimated, nothing is scraped from third-party aggregators.

A permissionless, globally distributed validator set secures every byte of data posted to Celestia — ranked here by bonded stake, not by who runs the biggest marketing team.

Every endpoint, by section
Everything below is a real, public, read-only endpoint — no key required. Each group reads from the chain's own infrastructure directly, not from a cached third-party dashboard.
Mainnet
celestiaChain-wide state from Celestia mainnet — block height, data-availability volume, validator set, governance and treasury. /api/mainnet alone returns every field below in one call; each narrower path returns just that slice.
The full mainnet object — everything the five endpoints below return, combined.
Current finalized block height, straight from Celenium's indexer.
Data-availability throughput: how much has actually been posted, and by how many accounts.
The real bonded validator count (not the raw registered-set size, which includes jailed/unbonded entries) plus total voting power.
Total TIA supply, bonded vs. not-bonded split, and the bonded ratio computed from both.
Lifetime proposal count, how many are currently in an open voting period, and the community pool balance.
The chain's own slashing module parameters — the actual rules a validator is held to, not a description of them.
The original lightweight snapshot this page's hero numbers are built from: height, blob volume, TIA price, block capacity headroom.
Testnet · mocha-5
mocha-5The same shape of data as mainnet, read independently from Celestia's public mocha-5 testnet — its own indexer, its own LCD, never derived from mainnet numbers.
The full mocha-5 object — everything the three endpoints below return, combined.
Current mocha-5 block height.
Testnet data-availability throughput — tx count, accounts, namespaces, blob volume.
Registered validator count and total voting power on mocha-5.
Total supply and bonded ratio for mocha-5.
Bridge
IBC · BlobstreamHow connected Celestia is to the rest of Cosmos (IBC) and to Ethereum (Blobstream) — both numbers read directly from chain state, not a bridge operator's own status page.
The full bridge object — both endpoints below, combined.
Total open IBC light clients from Celestia to every counterparty chain it has an active connection with.
latestBlock() called live on the real SP1Blobstream contract on Ethereum mainnet via eth_call, compared against Celestia's own current height, to get an honest relay lag — in blocks and hours.
Fibre
mocha-5 · via CumuloCelestia's Fibre data-availability relay network, read from Cumulo's public Fibre Network Monitor — a third party that probes Fibre hosts from four live regions every minute. We don't run these probes ourselves; we read their published results.
The full Fibre object — everything the four endpoints below return, combined.
Network readiness against the 2/3 stake threshold — how many validators are actually ready, not just registered.
Quorum round-trip latency measured live from four probe regions — US, EU, CA, AS.
Host concentration — how many distinct countries and hosting providers the Fibre network is spread across.
Balance currently held in escrow by the Fibre module.
