Chain vitals
Sampled from the public JSON-RPC endpoint.

Block cadence
Seconds between consecutive blocks across the sampled window. The gap since the newest block is shown separately below — it is orders of magnitude larger, and plotting it on this axis would flatten everything else into a single line.
Protocol reference
Read from the reference client's source, not measured. These are the constants a node must agree on to be part of chain 8.
JSON-RPC endpoints
Every RPC URL referenced by project repositories, docs, or chain registries, probed with a live eth_blockNumber call.
Services and hosts
HTTP reachability of project sites, explorers, and service subdomains. The failure kind matters: NXDOMAIN means the name is gone; 526 means DNS and the CDN still answer but the origin behind them does not.
Domain registration
Straight from registry RDAP. Registration and expiry dates are the registry's own, not inferred.
Peer-to-peer bootnodes
TCP reachability of the bootnodes compiled into the reference client. A successful handshake proves only that something listens on the port — not that it speaks devp2p or is in sync.
Sourced timeline
Dated items from official project channels. Each entry links to the source it was read from. Entries whose date could not be established are listed as unknown rather than placed on the line.

Communication channels
Current reachability and, where a platform exposes it publicly, membership and most recent activity.
Method
How each figure on this page is produced, so you can reproduce or refute it.
- Chain vitals
- The probe issues
eth_blockNumber, then walks back 200 blocks witheth_getBlockByNumber, recording each block's timestamp, transaction count and author. The silence, cadence, empty-block rate and producer count are computed from those blocks. - Endpoint status
- One HTTP
GETor one JSON-RPCPOSTper target. The failure kind is recorded verbatim:NXDOMAINis a hostname that no longer exists;526is a live CDN in front of a dead origin. - Domains
- RDAP queries against the registry for each TLD. An RDAP
404means the registry holds no record for that name — the domain is unregistered. - Timeline and channels
- Public feeds and APIs only — RSS, Atom, the GitHub REST API, and public invite/about endpoints. Every dated item links to the source it was read from.
Every figure is reproducible from the raw data:
/data/status.json ·
/data/sources.json.
The probe that produced them is tools/probe.py in the repository.
