Today’s Cryptocurrency Headline

Cardano (ADA) launches the first ZK-Rollup Layer 2 solution, Orbis, which aims to support DeFi applications and blockchain ecosystems by improving scalability and transaction throughput. Transactions occur off-chain on the Orbis layer 2 and are bundled together into a single ZK (zero-knowledge) proof which is submitted on-chain to the Cardano layer 1 and verified. Orbis has two main components: Provider and Verifier, the former is an off-chain system and its purpose is to construct zkSNARK proofs verifying the occurrence of transactions. The latter is an on-chain smart contract that accepts on-chain asset inputs, locking them up in the contract so they can be used on the rollup without the risk that they will be double-spent.
