Rosetta Network | Bitcoin Layer 2 (2024)

What is the Rosetta Network?

Rosetta is a Bitcoin Layer 2 Inscription Network, designed to address challenges pertaining to the verifiability, interoperability, and practical utility shortcomings inherent in the Inscription and BRC-20 protocol.

The Rosetta protocol stack is structured into four layers: Bitcoin Layer, Inscription Layer, BRC Layer, and Application Layer, arranged in a bottom-to-top hierarchy. The following graphical representation illustrates this architecture.

• The Bitcoin Layer utilizes the robust network secured by all Bitcoin miners to ensure permanent data storage for the Inscription and BRC-20 protocol.

• The Inscription Layer is a supplementary protocol based on the Ordinal Theory, associating inscriptions with each $Sat.

• The BRC Layer builds upon the Inscription Layer, providing a token protocol that updates token balances through predefined operations on inscriptions.

• The Application Layer encompasses applications centered around BRC-20 tokens.

Before the introduction of Rosetta, both the Inscription Layer and BRC Layer were defined artificially by Ordinal Theory and BRC-20 Protocol, controlled by centralized data indexers. Despite inscription data being recorded on the Bitcoin ledger, off-chain logic for resolving inscriptions and updating BRC-20 token balances presented verification challenges. Additionally, the absence of smart contract support in the Bitcoin network hindered the establishment of an application ecosystem around BRC-20 tokens.

What Benefits does Rosetta Network bring to Bitcoin?

• Cross-chain Interoperability: The Rosetta Bridge, operating on a decentralized cross-chain protocol, facilitates interoperability and enables Turing-complete smart contract functionality for BRC-20 tokens, opening up numerous opportunities for the BRC-20 token application ecosystem!

• Strengthened Consensus Framework: Rosetta introduces decentralized data indexers, supported by Bitcoin miners, forming a consensus network. This guarantees that both the Inscription Layer and BRC Layer benefit from the security of the Bitcoin network.

• EVM Compatibility: Rosetta enables Bitcoin to seamlessly integrate with the Ethereum Virtual Machine (EVM) and its surrounding ecosystem, enhancing compatibility and interoperability between the two networks.
