Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

Oasys architecture is built for game developers, offering a high-speed, zero gas fee experience to users by combining the best of public L1 and private L2 blockchain technology solutions. Oasys is a public blockchain specializing in games. It is launching with support from renowned game companies to revolutionize "Blockchain for the games." Oasys is an EVM-compatible protocol that adopts the Oasys Architecture. This unique architecture consists of a multi-layered structure, hub-layer, a highly scalable layer 1; and verse-layer, a special layer 2 using Ethereum's layer 2 scaling solution. Normal optimistic rollups establish the network through trust in a mechanism to verify fraudulent transactions by fraud-proof from an unspecified number of parties. In contrast, Oasys' Optimistic rollups establish the network through trust in two factors. Oasys eliminates the 7-day challenge period from optimistic rollups and allows transactions to be approved instantly.
