CoinEx Will List OP on June 1

Optimism is built according to a strong design philosophy that stands on four main pillars: simplicity, pragmatism, sustainability, and optimism. Optimism is an "Optimistic Rollup," which is basically just a way of describing a blockchain that piggy-backs off of the security of another "parent" blockchain. Specifically, Optimistic Rollups take advantage of the consensus mechanism (like PoW or PoS) of their parent chain instead of providing their own. In Optimism's case this parent blockchain is Ethereum. All Optimism blocks are stored within a special smart contract on Ethereum called the CanonicalTransactionChain(or CTC for short). Optimism blocks are held within an append-only list inside of the CTC. This append-only list forms the Optimism blockchain. Optimism block production is primarily managed by a single party, called the "sequencer," which helps the network by providing the following services: 1. Providing instant transaction confirmations and state updates. 2. Constructing and executing L2 blocks. 3. Submitting user transactions to L1. In an Optimistic Rollup, state commitments are published to Ethereum without any direct proof of the validity of these commitments. Instead, these commitments are considered pending for a period of time (called the "challenge window"). If a proposed state commitment goes unchallenged for the duration of the challenge window (currently set to 7 days), then it is considered final. Once a commitment is considered final, smart contracts on Ethereum can safely accept proofs about the state of Optimism based on that commitment. OP is an Optimism native token. The economics of Optimism ecosystem are designed to generate value for three constituencies: 1. Value accrues to tokenholders through the productive re-deployment of sequencer revenue. 2. Value accrues to contributors and builders directly from retroactive public goods funding and the markets it enables. 3. Value accrues to users and community members from ongoing airdrops of OP, from project incentives made possible by OP ecosystem funding, and from the benefit public goods provide.
