Indexed SiaBlockchain Data

Sia has been running since 2015, and it is a storage market with a ledger attached rather than a smart-contract platform. Blocks are mined under proof of work on a ten-minute target, and the ledger is a UTXO design in the same family as Bitcoin: value sits in outputs, and an address is the hash of the conditions required to spend one rather than of a single key. What makes it different is a third kind of object. A file contract commits a renter’s payment and a host’s collateral for a fixed term, and the host has to post a storage proof to be paid. There are two assets: siacoin, whose block subsidy declines toward a fixed floor so issuance never stops, and 10,000 Siafunds, created at launch, which take 3.9% of every storage payout. The v2 hardfork activated at block 526,000 in June 2025 and changed the transaction format.

SonarX indexes the objects the protocol actually keeps: blocks and transactions, siacoin and Siafund outputs, file contracts with their terms and collateral, contract revisions and renewals as they reach the chain, storage proofs and the payouts or forfeits that follow, and derived balances. The same normalized model is used on every chain SonarX covers, so storage activity joins to other networks in one query.

Full historical coverage is available today as a data-share or a file delivery. Real-time delivery is enabled on request.

A contract’s life is mostly invisible. Renters and hosts revise their agreement between themselves and only the settled state is recorded, so the chain gives you formation, the final revision, and then either a valid storage proof or a forfeited collateral. Reconstructing what a host actually earned means matching those records across the proof window rather than summing transfers. The format change is the other consideration: history written before and after the 2025 hardfork uses two transaction encodings, and a dataset that decodes only the newer one silently loses the first decade.

Host economics is the first workload: what a provider committed as collateral, what it collected on proof and what it lost by failing one, restated per contract and per period. Storage-price research is the second, because contract terms carry a price for a quantity over a duration, which makes this one of the few public markets where the cost of rented capacity is directly observable. Arweave is the usual comparison there, since it prices permanence once instead. Siafund revenue accounting is the third and depends on following payouts into claims. Treasury reconciliation is the fourth, and wallet analytics covers the address-level side of that work across chains.

Tell us the delivery target, how far back you need and how fresh it has to be, and the share is scoped against that. Say whether contracts have to be reconstructed across the format change, because that decision shapes the backfill. The published coverage matrix for every network SonarX indexes lives in the data documentation, and the rest of the catalogue is at all indexed chains.
