What is BRC2.0?

BRC2.0 is EVM execution anchored to Bitcoin, using Ordinals inscriptions as the data and ordering layer, and designed to be fully compatible with BRC-20 assets.

• Developers write and deploy standard Solidity smart contracts.

• Users interact with those contracts by submitting Bitcoin transactions.

• Contract state is computed deterministically by replaying inscriptions through an EVM execution engine.

• Bitcoin provides transaction ordering and the fee market.

• The EVM provides programmability.

Everything else is intentionally minimized.

There are:

• No bridges

• No multisignature custodians

• No sequencers

• No validator networks

• No gas token

• No Layer 2 trust assumptions

For Ethereum developers, the mental model is straightforward:

• Execution semantics follow the EVM

• EVM bytecode and calldata are delivered via Bitcoin blocks and inscriptions

• Gas is prepaid through inscription size, not a native token

For builders accustomed to Layer 2 systems:

• Users do not need new wallets

• Assets are not wrapped or bridged

• Withdrawals do not depend on committees or challenge periods

• Failure modes are explicit and verifiable on Bitcoin

Why this matters:

• You get expressive smart contracts without departing from Bitcoin’s security model

• You reuse the existing Solidity and EVM tooling ecosystem (such as Foundry, Hardhat)

• You can build Bitcoin-native applications that interact directly with BRC-20 tokens and introspecting Bitcoin transactions.

• Users only pay Bitcoin transaction fees—there are no additional protocol-level costs

Don’t think it’s “Ethereum on Bitcoin”. It is Bitcoin as the base layer, with the EVM as a programmable execution module, designed to integrate cleanly with existing developer workflows while avoiding new trust assumptions.
