You certainly remember those airdrops where you had to complete tasks, then the project takes a while to run its checks, and when it comes to distributing rewards, it’s a list on a Google Sheet where you have to look for your address, or a claiming page where you have to check your eligibility.
How can we be sure these distributions were done in good faith? How can we be sure no insider wallets were added? Only them know…
And that’s not just an airdrop problem. It’s a data problem.
It’s true that blockchain made transactions verifiable.
But a smart contract structurally can’t read certain data, like data from 6 months ago. It only sees the present moment, or very recent data.
A human can of course collect the onchain data and run the calculation themselves. But you can see how costly that is. And even if it’s programmed, that computation would far exceed the gas limit of a single block.
So the data is usually collected and the calculations done on a server off the chain. Then they come back with the results.
Without you being able to verify that they’re correct or that they follow the promised rules.
That’s the “trust me bro”. 
This is exactly what @SpaceandTime fixes. Space and Time is the data blockchain securing onchain finance, backed by M12, Microsoft’s venture capital fund. Its mission: power verifiable data for AI, tokenization, and DeFi.
How it works
They built a chain that acts as a database, collecting blockchain data in real time and in a decentralized way. Validators agree on a cryptographic commitment of that data, so nobody can quietly change it afterwards.
Then a zero-knowledge (ZK) coprocessor called Proof of SQL makes it possible to verify that the exact calculation was performed. The queries are written in SQL, a language already used for databases, so builders don’t need to be cryptographers.
The smart contract doesn’t redo the calculation. It just checks the proof.
Back to our airdrop. If you take part in an airdrop, the data you produce is collected on their layer. As soon as the project wants to announce results, it just sends the query through the infrastructure, and the result comes back with its proof. Which lets you verify the project ran exactly the check it announced. Not another one.
Verifiable data for AI, tokenization and DeFi
DeFi. On Binance, for example, if you’re VIP, you get discounts on trading fees. But it’s not as simple to do on decentralized protocols as it is on a CEX. Fees are usually set by the protocol as a percentage with no real loyalty mechanism, because certain details would need to be verified, like your 30-day volume. With an architecture like this, a decentralized liquidity pool can verify your volume and apply discounts. In a decentralized way. The official Uniswap hooks materials already describe templates that use historical-data queries to inform swap-fee discounts. Same for rewards: eligibility can be proven from your past transactions.
AI. AI agents need data about balances, protocol activity and past transactions before making financial decisions. With Space and Time, an agent can use a proven query result, for example a protocol’s recorded fees over a given period, before deciding to interact with it. No more acting on a number nobody can check.
Tokenization. Tokenized assets depend on records of holdings, cashflows and valuations. Space and Time supports custom offchain datasets alongside blockchain data and can prove calculations over those records, like the ones that feed net asset value (NAV) reports, or a tokenized stock’s trading volume across several pools, combined into one verified figure.
The role of $SXT
The token that enables the decentralized coordination of the chain layer of the infra is $SXT. It’s used to pay for network workloads (queries, data insertion, verifiable compute), and it’s staked to support validator security: a validator who cheats puts its stake at risk.
Maybe this becomes the industry standard for anything that requires manipulating onchain data. Because if data is computed elsewhere and sent afterwards, it’s part trust me bro.
Who here has ever been through a manipulated airdrop?
