Layer 2

Ethereum serves as the foundational settlement layer for decentralized finance (DeFi), Real-World Asset (RWA) tokenization, and Web3 capital markets. By enabling automated, borderless financial transactions through smart contracts without traditional intermediaries, Ethereum provides global access to liquidity. However, executing transactions directly on Ethereum's mainnet (Layer 1) faces physical throughput limits, causing network congestion and high gas fees during peak activity.

Solana is a decentralized Layer 1 public blockchain built for high throughput and low latency, providing high-performance infrastructure for smart contracts and decentralized applications through architectural optimizations such as Proof of History and parallel transaction processing. As blockchain technology expands into decentralized finance, digital asset issuance, trading, gaming, and other on-chain interactive applications, network performance and scalability have become critical constraints, and Solana is often examined as a direct attempt to solve them.

The standard path to bridge assets to Linea: enable Linea Mainnet (Chain ID 59144) in an EVM wallet, connect at bridge.linea.build, choose the All Bridges aggregator or Native Bridge, confirm on the source chain, then verify the destination address and token contract on lineascan.build. Typical time: 5–15 minutes; difficulty: beginner to intermediate.

LINEA has a total supply of 72,009,990,000 tokens (~85% ecosystem, ~15% Consensys with a five-year lock). ETH is the sole gas on Linea; LINEA coordinates incentives. After costs, net surplus follows dual-burn: ~20% ETH burned, ~80% used to buy and burn LINEA. The Association executes; the Consortium stewards strategy and funds.

Linea is a Consensys-incubated zkEVM Layer 2 that processes Ethereum-compatible transactions off-chain and settles proofs to Ethereum. ETH pays gas; LINEA funds ecosystem growth and participates in a dual-burn design that burns ETH and LINEA from net fee surplus.

Linea uses zkEVM validity proofs with ETH-only gas and LINEA dual-burn incentives; Arbitrum and Optimism are Optimistic Rollups with fraud proofs and ~7-day official-bridge windows, leading in DeFi depth and OP Stack Superchain tooling respectively.

COTI V2 is a Layer 2 network dedicated to privacy computing. Utilizing Garbled Circuits and Confidential Computing technologies, it delivers a Smart Contract execution environment for Web3 applications capable of handling sensitive data. This allows transactions, identity verification, financial logic, and AI data to be computed on-chain with robust privacy safeguards.

$ADI serves three roles in the ADI Chain ecosystem: native Gas, ecosystem settlement medium, and treasury-backed staking—with a fixed genesis supply of 999,999,999 and no inflationary minting. Gas and L3 domain settlement both consume $ADI; staking rewards come from treasury reserves rather than new issuance. Community receives 35%, treasury 25%, and five other categories follow distinct unlock schedules; private sale, team, and partners each carry a 12-month cliff.

ADI Chain L3 compliant chains are Layer 3 ZK Rollups that settle on ADI L2, which in turn settles on Ethereum L1, forming an L3→L2→L1 validity-proof chain. Each L3 has its own Sequencer, Prover, and Diamond Proxy contract while sharing Bridgehub and StateTransitionManager; batches settle on L2 through Commit, Prove, and Execute, with finality propagating upward through the stack.

The core difference between ADI Chain and Arbitrum or Base is that ADI Chain prioritizes government and institutional compliance, offering native L3 compliant chains, sovereign stablecoins, and an RWA deployment framework with ZK validity proofs; Arbitrum and Base focus more on general-purpose DeFi and consumer applications, with compliance typically assembled at the application layer or through extensions such as Orbit or Superchain, and ecosystems weighted toward institutional DeFi depth and Coinbase retail distribution respectively.

ADI Chain is an institutional-grade zkRollup Layer 2 on Ethereum, powered by zkSync OS and the Airbender zero-knowledge proof system, delivering customizable L3 compliant chains, stablecoin settlement, and RWA tokenization infrastructure for governments, banks, and enterprises. $ADI serves as the network's native Gas token; ecosystem partners include Mastercard, BlackRock, Franklin Templeton, and M-Pesa.

The Base team has not yet issued a native governance token; network gas fees are paid directly in ETH. However, as the ecosystem gradually develops, the community is exploring the creation of a native asset system for Base, with B20 emerging as a new token standard of interest. B20 leverages on-chain inscriptions and a fair launch mechanism to emulate asset issuance models like Bitcoin Ordinals and BRC-20.

Base and Optimism are both Ethereum Layer 2 networks built on the OP Stack and are part of the OP Superchain ecosystem. They share a similar underlying technical architecture, including Optimistic Rollups, modular design, and Ethereum settlement mechanisms, but differ significantly in governance, tokenomics, ecosystem positioning, and development objectives. Optimism is the developer of the OP Stack and the originator of the OP Superchain, with a focus on advancing Layer 2 infrastructure and ecosystem cooperation. Base, launched by Coinbase, is more oriented toward consumer applications, payment use cases, and user growth.

Base’s application ecosystem spans multiple domains including DeFi, payments, social networks, NFTs, on-chain identity, and AI Agents, making it one of the most active Ethereum Layer 2 ecosystems today. Backed by Coinbase’s user base and low-cost trading environment, Base has attracted a substantial number of developers and application deployments, encompassing decentralized exchanges, lending protocols, stablecoin payment platforms, and emerging on-chain social products.

Base and Arbitrum are both Layer 2 networks built on Ethereum, employing Rollup technology to reduce transaction costs and enhance network performance. However, they differ in technical architecture and strategic ecosystem direction. Base is built on the OP Stack, making it a key member of the OP Superchain ecosystem, with a stronger emphasis on consumer applications, payments, and social use cases. Arbitrum, on the other hand, adopts the Nitro architecture, giving it a competitive edge in DeFi, on-chain infrastructure, and the developer ecosystem.
