Technical Architecture

The technical architecture and workings of an Ethereum Cross-Rollup product are described as follows. This includes the communication mechanism between the Rollup chain and the Ethereum main chain, as well as the asset locking and unlocking mechanisms. The technical measures taken to ensure asset security and prevent double-spending attacks are highlighted.

The Cross-Rollup product on Ethereum is built on a layer-2 scaling solution that improves the speed and scalability of transactions while still maintaining the security of the underlying blockchain. The product relies on Rollups, which are Layer-2 scaling solutions that allow for the processing of a large number of transactions in a single batch before submitting the batch to the Ethereum main chain for verification. This process reduces the amount of data that must be processed on the Ethereum mainnet, resulting in faster transaction speeds and lower fees.

In terms of communication, the Rollup and the Ethereum mainnet use a two-way pegging mechanism to maintain consistency between the two networks. This means that assets can be locked on the Ethereum mainnet and then unlocked on the Rollup network, or vice versa. This is achieved through the use of smart contracts that hold the locked assets until they are unlocked on the other chain.

To prevent double-spending attacks, the Cross-Rollup product employs various technical measures, including fraud-proof mechanisms and signature verification. Fraud-proof mechanisms detect and prevent invalid transactions by allowing users to submit proof of fraud to the system. Signature verification ensures that only the owner of an asset can initiate a transaction, preventing unauthorized use.

Overall, the technical architecture of the Cross-Rollup product on Ethereum is designed to provide faster and more scalable transactions while still maintaining the security of the underlying blockchain. The product's communication and asset locking mechanisms, as well as its various fraud prevention measures, all work together to ensure the safety of users' assets and prevent any malicious attacks.
