Key Points
- Starknet aims to utilize Bitcoin and Ethereum on a single layer 2 network for settlement.
- The Starknet Foundation has outlined a roadmap for scaling Bitcoin transactions from 13 per second to thousands.
Starknet has announced plans to employ Bitcoin as a settlement layer in conjunction with Ethereum. The goal is to link the two most significant blockchains on one layer 2 network.
Starknet’s Bitcoin Roadmap
The Starknet Foundation revealed a roadmap on March 11. The roadmap details how the network could scale Bitcoin from its current capacity of 13 transactions per second to thousands. Despite Bitcoin’s deep liquidity and security, its limited programmability has made decentralized finance development challenging. Starknet aims to rectify this.
Starknet is advocating for the adoption of OP_CAT, a proposed Bitcoin update. This update would enable users to establish spending conditions for Bitcoin and facilitate zero-knowledge proofs. Zero-knowledge proofs are cryptographic techniques that verify transactions without disclosing any personal data. This would create a fully trustless bridge between Bitcoin and Starknet.
In the absence of OP_CAT’s adoption, Starknet plans to use alternatives like BitVM. BitVM is a verification method that enables Bitcoin to execute smart contract logic without altering its base layer.
Supporting the Shift
To facilitate this transition, the Starknet Foundation has initiated BTCFi Season. This program is centered on expanding Bitcoin’s financial use cases. The foundation has also entered into a partnership with the Bitcoin wallet, Xverse. Xverse is working towards integrating Bitcoin DeFi into its wallet.
StarkWare, the core technology provider for Starknet, has transferred a portion of its treasury into Bitcoin. This action has resulted in the creation of a Strategic Bitcoin Reserve.
Vitalik Buterin, the co-founder of Ethereum, endorsed the concept of a highly secure Bitcoin layer 2 with robust security in a March 11 X space. Buterin suggested that it might “make crypto payments great again.”
He noted that scaling problems have hindered Bitcoin’s original purpose of serving as a peer-to-peer cash system. Current solutions, like the Lightning Network, have their limitations.
The Lightning Network has encountered issues such as liquidity constraints, routing failures, and the requirement for always-online nodes. These problems limit its effectiveness for large-scale payments.
