Ethereum blobs (EIP-4844) as a storage layer Storage

Free tier	No free tier. Live cost at time of check: $0.012 per MB as blobs (vs $11.01/MB as calldata). 128 KB per blob package, separate blob fee market. unit MB; metered on unstated
Price	none stated
Per-object cap	128 KB per blob (128000 bytes)
Retention	~18-day retention; per-block blob count cap; cost floats with the blob fee market. (18 days)
Egress	Free to read while data exists, but data is pruned by consensus nodes after ~18 days. Retrieval after that depends on third-party archival indexers (Blobscan etc.), not on Ethereum.
Identity	card derived from the record's prose, not from an identity field, and no signup was executed: No free tier. Live cost at time of check: $0.012 per MB as blobs (vs $11.01/MB as calldata). 128 KB per blob package, separate blob fee market. Data is intention
Limits	per-object-cap 128 KB per blob source ~18-day retention; per-block blob count cap; cost floats with the blob fee market.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest rest
Tooling	blobkit.org (TypeScript SDK for blob transactions), Blobscan API, standard Ethereum JSON-RPC.
Composes with	Multiply cost, not capacity: 10 TiB/month = 10,485,760 MB x $0.012 = ~$125,800/month, and the data expires in 18 days regardless of payment.
Reliability	Data is intentionally ephemeral by protocol design — the network is built to forget it after the DA window.
Notes	No free tier. Live cost at time of check: $0.012 per MB as blobs (vs $11.01/MB as calldata). 128 KB per blob package, separate blob fee market.
Evidence rung	reported One page read moves it to documented.
Checked	2026-10-21 (inherited); stale on 2026-11-04
Parsed numbers	`$.limits[0].value` limit:per-object-cap 128.0 KB
