Bitcoin & Beyond is an educational series by the team at The Rollup The focus of the event was on an emerging and new class of Bitcoin builders. The goal is to gain deep technical insight into scaling innovations through spaces, interactive presentations and panels.
In our latest feature for Bitcoin & Beyond, we’re exploring BOBWe caught up with Dom, co-founder of BOB, to understand their staged approach to development and new merged mining protocol. Dom, BOB co-founder, was interviewed to learn more about BOB’s development process and new protocol. Optimine.
Layer 2 Solutions Reignite Innovation in Bitcoin
Dom made it clear from the beginning that BOB’s main motivation was to get BOB into trouble. “to make it a lot easier for people to build on Bitcoin.” He pointed out the huge opportunity that Bitcoin has to be as easy-to-programme as Ethereum and still maintain the security standards it is known for.
As many others have done, he expressed his gratitude for this current wave of innovative energy that has energized the Bitcoin eco-system. “There are so many new projects now sharing that same vision. And we think it’s really worth it to bring all that innovation to Bitcoin.”
BOB believes that three factors are crucial for the growth of layer 2 applications.
1. Bitcoin: The best choice for security and economy
2. The developer ecosystem needs infrastructure to flourish
3. New projects can be launched with liquidity
“It’s about creating a network where liquidity and users can seamlessly transition between projects, enhancing the overall vibrancy of the platform.”
Dom also spoke about BOB’s position in the marketplace: “Our approach is quite unique—we’re the only ones aiming to create what we call a hybrid L2.”
BOB’s rollup solutions are designed to be integrated with the Bitcoin stack using lightweight clients. It also works as a Ethereum rollup to make it easier for the Ethereum community. “A lot of people are used to bridging over from Ethereum to platforms like Arbitrum, Bays, or Optimism,” Dom said. BOB’s familiarity with Ethereum makes it an appealing platform for developers and users.
The current building is located on OP StackThe team has focused on making the Ethereum experience for users and developers as natural as possible in order to minimize friction. Dom has also confirmed that at this time, there is no way to bring Bitcoin onto the Ethereum platform using bridges with minimal trust.
BOB Road Map
BOB will roll out the protocol over a number of phases that are designed to enhance platform capabilities incrementally:
Phase One: Bootstrapping
This initial phase, launched on 1st May, focuses on establishing BOB, as an optimistic Ethereum Roll-up, using the OP Stack, but without Bitcoin security.
The second phase is the integration of Bitcoin proof-of-work security
The next step is to transition BOB’s cryptographic security to Bitcoin using Optimine. Optimine is a mining protocol for merging that hardens the system security.
The transition to Bitcoin roll-up
This stage aims to switch the platform to Bitcoin-based, dependent on the development of new technologies like BitVM and fraud-proof schemes.
Phase Four: Implementation Zero-Knowledge proofs
Bitcoin may adopt the technology, but until then, it is planned to integrate zero-knowledgeproofs in this final phase. It would improve privacy and efficiency of transaction.
OptiMine – Developing OptiMine
The focus of the current team is “Optimistically Sequenced Merged Mining“, is a technique which begins to integrate Bitcoin’s safety into BOB. Dom explains, “OptiMine extends traditional merged mining by separating block production from proof-of-work finalization.” This, he says, will enable the protocol to process transactions quickly while maintaining the integrity that is typically associated with Bitcoin.
Security and Efficiency OptiMine
- Optimistic block productionA sequencer produces blocks every 2 seconds, which is the standard for developers working in the Ethereum ecosystem. OptiMine speeds up transaction closure, which is important for the user experience. “Compared to traditional merged mining methods, OptiMine allows for quicker finality, enhancing overall system efficiency,” Dom Adds.
- Bitcoin finalization securedBitcoin miners in OptiMine validate blocks generated by sequencers. They do this by embedding a BOB reference hash within Bitcoin block, and then adding them to the Bitcoin chain. The use of centralized sequencers is significantly reduced by this validation.
- Re-orging resistanceThe Optimine system separates block-production from proof-ofwork to reduce the chance of a hacker attacking the chain and rewriting its history.
- Merged Mining EfficiencyOptiMine uses the existing Bitcoin mining infrastructure for BOB rollups, without adding any additional costs.
BOB’s vision is to bring together two diverse ecosystems and create a flexible platform by leveraging their strengths.
“We want to essentially be the platform in between Bitcoin and Ethereum. And if you have assets from Ethereum, they should have Ethereum security. If you bring in assets from Bitcoin, they should have Bitcoin security and you should be able to use both on Bob.”
