Convert Optimism OP to EvidenZ BCDT

Optimism is a network of chains called the Superchain, built on the open-source OP Stack. OP Mainnet was the first chain, with several others now operating on the OP Stack architecture, including Base (by Coinbase), Unichain (by Uniswap), Ink (by Kraken), and World Chain (by Worldcoin). The OP Stack serves as a framework for Ethereum Layer 2 chains and supports significant L2 activity. Every OP Chain in the Superchain contributes back to the Optimism Collective and all chains follow a standardized revenue-sharing model: the greater of 2.5% of total chain revenue or 15% of onchain profit (defined as fees minus L1 gas costs) is paid back to the Optimism. By aligning economic incentives across many chains, Optimism aims to transform Ethereum scaling into a sustainable flywheel by delivering fast, low-cost transactions while reinvesting in the future of the ecosystem. OP holders participate in governance to shape protocol upgrades, funding decisions, and more

Blockchain Certified Data Token (BCDT) is the token linked to the EvidenZ framework, used by the company BCdiploma to allow hundreds of institutions to issue diplomas in a digital, decentralized and secure way. The BCDT is required to issue each certificate on any blockchain. It is a utility token: for each certification, part of the BCDT used is burned by the smart contract of the EvidenZ ecosystem, reducing its total quantity. 40M BCDTs were issued during an ICO in January 2018: no more BCDTs will be issued after this date.
