Our data, sealed on-chain every 5 minutes
Funding, open interest, liquidations, depth, whale prints, flow toxicity, premiums, tokenized stocks, insurance funds and venue withdrawal switches that we compute are sealed into one Merkle root per five-minute window, signed, and written to public blockchains. Nobody, including us, can change a published number afterwards without it showing. You do not have to trust this page: every check below can be repeated from the chains alone.
Punctuality
One bar per five-minute window: the seconds between the end of the window and the block that carries its seal on Solana. The protocol asks for a signature within 60 seconds and calls an anchor late after 120.

Verify a record in your browser
Pick a record and, if you like, an epoch. For the stream id built into this page's code, your browser reads the genesis and the authorization log from Base and checks the governance signature, recomputes the record's proof with open cryptography (Keccak-256, secp256k1), and reads the anchor from Solana. For epochs older than about two days only the daily epoch sealed on Base can be checked here; the one-file verifier under Verify without us checks every epoch on both chains and proves that nothing was left out. Our API only supplies the record and where its anchor is; every byte is checked in your browser.
- 01The genesis on Base hashes to this stream's idwaiting
- 02The authorization log on Base carries the governance signaturewaiting
- 03The record is a valid 104-byte leafwaiting
- 04The leaf hashes up the Merkle path to the rootwaiting
- 05That root is the one inside the signed manifestwaiting
- 06The manifest hashes to the published commitmentwaiting
- 07The signature recovers to a signer the on-chain log authorizes for this epochwaiting
- 08The manifest is on chain under its witness key, after its window closedwaiting
Newest epochs
Each row is one five-minute window. The links open the transaction that carries the seal.

At the end of every five-minute window the engine reads our recorded tables. Only inputs stamped before the window end count, and a window is never built late: an outage becomes one visible gap, never invented values.
Seal
Each record becomes a fixed 104-byte leaf with its value, source count, coverage and age. The leaves form a Merkle tree; the root goes into a 200-byte manifest that also names the previous manifest, so the epochs form a chain.
Sign
An isolated signing service signs the manifest. It has no network access and refuses to sign a second, different manifest for the same epoch, whoever asks.
Anchor
The signed manifest is written to Solana every epoch and to Base once a day under an address derived from the stream and the epoch number, so anyone can find it without asking us.
What this proves, and what it does not
Plain limits, stated up front.
- It proves that a number was published at that time and has not been changed since. It does not prove that the number is right: methodology and sources remain ours, and the methodology text is sealed by hash with every epoch.
- Beta: the stream's governance is a single key, generated on the founder's own machine and never on our servers. The production stream will use two of three hardware keys.
- Beta: Base receives one seal a day instead of one per epoch. Epochs are hash-chained, so that daily seal covers everything before it.
- Most feeds are Class B: computed from our recorded tables, which are not republished. Since catalog beta-0.5 one feed is Class A: BYK.FUNDING.COMPOSITE.A, which anyone can recompute exactly from the raw inputs served for every epoch at /api/v1/proof/snapshots.
Verify without us
Everything on this page comes from a public API and from the two chains. The stream id below is the one value to pin; the rest follows from it.

Questions
Why put market data on a blockchain at all?
So that history cannot be rewritten. A data vendor can quietly fix, backfill or restate numbers. Once a five-minute epoch is sealed and anchored, any later change to a record breaks the Merkle proof and everyone can see it.
Is the data itself on-chain?
No. Only a 200-byte manifest with the Merkle root and a signature goes on-chain. The records stay with us and are served with their proofs. That keeps the cost at a few dollars a month and lets paid data be sealed without being given away.
What does a missing epoch mean?
If the engine is down or late, it does not invent the window. The next epoch carries one gap manifest that states which windows were missed. Gaps are part of the public record.
Can I check this with my own code?
Yes. The format is documented byte by byte, the hash is Keccak-256, the signature is secp256k1 over the manifest hash, and the Merkle tree follows RFC 6962. The Proof API returns every byte you need, and the anchors can be read straight from Solana and Base.
Does it cost members anything?
No. Proofs are free and need no account. A proof that required an account to be checked would prove little.
