Optimistic Ethereum, now primarily referred to as Optimism or OP Mainnet, is a layer-2 scaling solution for Ethereum focused on improving transaction speed and reducing costs while maintaining security through optimistic rollups.

Here's the latest based on recent activity:

Superchain Expansion: Optimism is pushing its "Superchain" vision, a network of interoperable layer-2 blockchains built on the open-source OP Stack. Recent posts highlight integrations like Unichain, with incentives starting April 15, 2025, and Soneium's growth strengthening the ecosystem.

Retro Funding: Optimism continues its Retroactive Public Goods Funding (RetroPGF), rewarding developers and projects that contribute to Ethereum’s ecosystem. A recent call for applications for the next round closes April 27, 2025, emphasizing fair rewards based on impact, not marketing. Over 2 million OP tokens were allocated this month for dev tooling and onchain builders.

Performance and Governance: The OP token governs the Optimism Collective, a decentralized system driving ecosystem growth. As of early 2025, OP’s price is around $0.65-$0.69 USD, with a market cap of about $1.14 billion. Q4 2024 saw an 11.3% increase in total value locked (TVL) to $756.1 million, though price performance remained flat, causing a dip in market cap rank.

Open-Source Commitment: Optimism is doubling down on open-sourcing its tech, with 131 GitHub repositories and contributions like the OP Stack powering chains like OP Mainnet and Base. This aligns with their mission to scale Ethereum collaboratively.

-How does Bitcoin work & where can I get a bitcoin wallet?
Bitcoin is software that runs on a number of distributed devices ranging from smartphones as mobile wallets, PCs as desktop wallets, to ASIC for mining. Transactions are relayed between nodes in a peer-to-peer fashion. In a few seconds a given block will be propagated to all other nodes on the network. While insuring that all nodes reach consensus on which are the valid blocks. The process of supplying new coins in the system is done via the process of mining. The mining software runs on specialized hardware and it tries to compute the hash of assembled transaction and a number called the nonce.
