Indexed BitcoinBlockchain Data

Bitcoin has produced blocks continuously since its genesis block on 3 January 2009. Blocks are mined under Nakamoto consensus with SHA-256 proof of work, targeting one block every ten minutes, and the difficulty target is recalculated every 2,016 blocks so that the interval holds as hashrate changes. There are no accounts. Value is held in unspent transaction outputs, and an address’s balance exists only as the sum of the outputs its keys are able to spend, which is the single fact that shapes everything about indexing this chain. The native asset is BTC, capped at 21 million and divisible into 100 million satoshis, with the block subsidy halving every 210,000 blocks. Ownership has been expressed through four generations of script over the chain’s life, from the original pay-to-public-key-hash and pay-to-script-hash forms to SegWit addresses in 2017 and Taproot in 2021, and the same owner often holds funds across several of them. Litecoin and the other UTXO chains inherited this design nearly unchanged.

SonarX indexes blocks and headers, transactions, inputs and outputs, the scripts that lock them, the derived UTXO set and address-level positions built from it. The same normalized model is used on every chain SonarX covers, so Bitcoin can be joined to other networks in one query rather than reconciled between two pipelines afterwards.

Full historical coverage is available today as a data-share or a file delivery. Real-time delivery keeps the same dataset current to chain tip. Point-in-time balance tables can be enabled for Bitcoin on request. Kafka streaming carries the same records as a live topic today.

The protocol keeps no balances, so an address-level view has to be constructed rather than read. SonarX replays every output creation and spend to maintain the UTXO set, then derives positions from it, resolving the four script generations that put one owner behind several address forms. Inputs reference outputs by transaction hash, so a transfer view is a join across blocks rather than a lookup of a transfer record. Reorgs are shallow but real, and outputs spent in an orphaned block have to be returned to the set rather than left consumed. Inscriptions have also pushed large payloads into witness data since 2023, which changes the size profile of a backfill without changing its shape.

Bitcoin is the chain institutions ask for first, and the work is rarely about smart contracts. Custody and treasury reconciliation needs holdings restated as at a date, across address formats and change outputs, which is a UTXO join rather than a balance lookup. Supply-side research uses the outputs themselves: UTXO age cohorts, realized cost basis, coin-days-destroyed and similar measures are only computable when the whole output history is present. Miner and flow analysis reads coinbase transactions and the movement out of mining addresses. And Bitcoin’s role as collateral elsewhere means BTC data increasingly gets joined to another chain, most often through Babylon.

Wallet analytics covers the address-level side of this work across chains, including the change-output problem that makes a Bitcoin wallet harder to follow than an account.

Tell us the delivery target, how far back you need and how fresh it has to be, and the share is scoped against that. Bitcoin history is available now, and streaming is provisioned on request. 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.
