Understanding the technology that makes VerifiedDraws tamper-proof and publicly verifiable
We use Chainlink VRF (Verifiable Random Function) to generate provably fair random numbers. This is the same technology used by major blockchain protocols and cannot be manipulated by anyone — not even us.
Why it matters: Traditional random number generators can be manipulated. Chainlink VRF uses cryptographic proofs that make manipulation mathematically impossible.
All draw data (entries, winner, timestamp, random seed) is stored on IPFS (InterPlanetary File System), creating a permanent, immutable record that cannot be deleted or modified.
Why it matters: Unlike traditional databases that can be edited or deleted, IPFS creates a permanent record distributed across thousands of nodes worldwide.
The draw is recorded on Polygon blockchain, creating a public, auditable trail that anyone can verify independently. Every draw gets a unique blockchain transaction hash.
Why it matters: Anyone can verify the draw was fair by checking the blockchain record. No trust required — the proof is mathematical and public.
Once the draw begins, the entry list is cryptographically sealed. No one can add, remove, or modify entries — not even the platform administrator.
The winner is determined by blockchain randomness and recorded permanently. Changing the result would require rewriting the entire blockchain — mathematically impossible.
Anyone can verify the draw independently using the blockchain hash. No special access or permissions required — the proof is public.
Unlike traditional systems where records expire or can be deleted, blockchain records are permanent. Verify a draw years later with the same proof.

The draw is proven fair — no trust required
Chainlink VRF (Verifiable Random Function) generates cryptographically secure random numbers with on-chain verification. The randomness is generated off-chain and proven on-chain using cryptographic proofs.
Draw data is stored on IPFS (InterPlanetary File System), a distributed file storage protocol. Files are addressed by their content hash (CID), making them immutable and permanent.
The draw is recorded as a transaction on Polygon, an Ethereum Layer 2 network. This creates a public, auditable record that can be verified on PolygonScan.
Entry lists are hashed using SHA-256 before the draw. This creates a cryptographic fingerprint that proves the entries were not modified after the draw began.
