Security of our NFT ticketing platform

The use of blockchain and specifically NFTs ensures that each issued ticket is unique, traceable, and tamper-proof. When a user purchases a ticket, it is created as an NFT and transferred to the user's wallet.

SellTix uses the carbon-neutral Polygon blockchain to issue its tickets.

To access an online event, users must have a ticket in their wallet, otherwise access will be denied. The ticket can be obtained either through purchase on the original event page OR acquired on the secondary market, such as OpenSea.io

For "web2" users unfamiliar with blockchain, we automatically create a wallet to store their purchased ticket(s). We have no knowledge of these wallets' private keys. These are encrypted with a password (which we don't know) using the PBKDF2 encryption algorithm with SHA256 hashing, a protection mechanism recommended by NIST.

These wallets don't belong to us, and a "web2" user can take full ownership of their wallet (only the owner user can decrypt it) and recover it's private key.
