ZK Validium

*DAC (Data Availability Committee) is a trusted set of nodes that stores copies of data offline. The DAC is required to make the data available in the event of a dispute. Members of the DAC also publish on-chain attestations to prove that the said data is indeed available.

ZK Validium is another key component of Wirex Pay’s ZK tech stack. It operates similarly to ZK Rollups but stores data off-chain, which provides even greater scalability. Here’s how ZK Validium enhances Wirex Pay:

• Off-Chain Data Storage: By keeping transaction data off-chain, Validium can process a higher volume of transactions without burdening the main chain.

• Scalability: This method allows for virtually unlimited scalability, making it ideal for applications that require high throughput and low latency.

• Privacy: Like ZK Rollups, Validium uses Zero Knowledge proofs to maintain the security and privacy of transactions.
