Blockchain Verification
Social RV uses the blockchain to prove sessions are truly double-blind. Blockchain sessions are precognitive, meaning the target is assigned after the session is submitted. This means no human could have known which target would be assigned beforehand, making it cryptographically impossible for anyone to have influenced or predicted the outcome.
📋How Our Blockchain Verification Works
Understanding the lifecycle that makes sessions provably blind
We store a list of target image fingerprints (SHA-256 hashes) on the Solana blockchain for our target pool, and we lock the set so it can't be modified further. This creates a permanent, immutable list of possible targets that will later be assigned to sessions via our Solana program.
You complete your remote viewing session and upload it. We submit a transaction to the Solana blockchain which includes a fingerprint of the session files, and a list of up to the last 50 targets you've done (so you don't get duplicate targets too frequently). At this point no one, not even Social RV, knows which target will be assigned yet.
The Solana blockchain finalizes our submitted transaction by including it in a new block. We retrieve the blockhash generated by the Solana validators for this new block, and use it as the random seed to select a target from our target pool. This blockhash is cryptographically unpredictable and cannot be influenced by us or anyone else.
We submit a second transaction which includes the blockhash from the first transaction, so our blockchain program can use it to select a target from the target pool and assign it to the session.
The target is selected using randomness that didn't exist when the session was submitted. The pool is sealed so targets can't be changed. All data is on-chain and independently verifiable.
