The sequencer fee consists of the L2 execution fee and the L1 data fee. It generates revenue by selling block space. The sequencer's role is adding and ordering transactions to Optimism.

The network also generates revenue through its centralized sequencer. OP token holders share governance rights with OP Citizens but maintain enough control over the Optimism network to accrue value. Tokens reserved for community are vested for 1 year or less. The majority of investors and core contributors are subject to 2-year lock-up periods. The token supply allocation includes 20% to be used retroactively for public goods funding, 25% reserved for ecosystem funds, 19% airdropped to eligible users, 17% to investors, and 19% to core contributors. OP launched with a total supply of ~4.3M tokens with a 2% perpetual inflation rate per year. The Optimism network currently generates revenue through a centralized sequencer, and is expected to share this with OP token holders at some point in the future. Within the collective, OP holders and OP citizens equally coexist in order to balance short-term incentives with the foundation's longer term vision. This is based on the working constitution per the Optimism Collective, which is a large-scale experiment in decentralized governance. Instead, OP holders share governance rights with 'appointed citizens'. A person familiar with the matter told Fortune in March that around 70% of overall tokens will go to registrants, with the rest going to insiders such as Tools for Humanity employees and the firm’s investors.OP is a new type of governance token that does not provide token holders sole governance rights over the protocol. Worldcoin is not launching its token directly on exchanges like Coinbase or Uniswap, instead airdropping it to users, who will be able to transact with it through crypto wallets. The immediate impact of the token launch is unclear. “There’s going to be a defined value attached to it-it’s just going to be an entirely different world that I think none of us can actually predict.” “General interest is probably going to be two orders of magnitude higher than it is now,” he said. In an interview with Fortune, Blania said Worldcoin hopes to have 1,500 orbs operational by the end of the year, as well as expand to new markets, with the launch of the token likely driving more interest for signups. Currently, only around 150 orbs are operational, and just 2 million people have signed up to the platform-a far cry from the hundreds of millions, or billions, that Worldcoin needs to create meaningful network effects.

With the launch of the token, Worldcoin enters a new phase. Blania and his team of engineers said Worldcoin’s protocol of iris scans was the only universal way to create a global identity verification system, with the token serving as an incentive mechanism to acquire users. Tools for Humanity developed a software development kit, or SDK, where other apps could use people’s World ID-generated after they are verified by an orb-in lieu of other login credentials, like emails and passwords. Since the November launch of ChatGPT and growing public awareness of generative A.I.-and the potential threats to employment and online identity-Worldcoin began emphasizing its “proof of personhood” system as uniquely capable of countering those concerns.

Tools for Humanity is also releasing a Worldcoin white paper. As part of the token launch, Worldcoin has migrated its protocol to the Optimism mainnet, a layer-2 blockchain built on Ethereum.
