Bitcoin & Past is an academic collection by the workforce at The Rollup targeted on a brand new and rising class of builders within the Bitcoin ecosystem. By areas, panels, and interactive displays, the target is to offer deep technical insights into progressive scaling tasks.
In our newest characteristic for Bitcoin & Past, we’re exploring BOB, a novel, hybrid, layer resolution that goals to marry Bitcoin’s strong safety with the agility of Ethereum. We caught up with Dom, co-founder of BOB, to grasp BOB’s staged method to growth and their new merged-mining protocol, Optimine.
Reigniting Innovation in Bitcoin By Layer 2 Options
From the onset, Dom was clear that BOB’s major motivation has been “to make it rather a lot simpler for individuals to construct on Bitcoin.” He highlighted the large alternative for Bitcoin to grow to be as simply programmable as Ethereum whereas sustaining the strong safety it’s recognized for.
Like many others, he echoed his appreciation for this wave of innovation at present energizing the Bitcoin ecosystem. “There are such a lot of new tasks now sharing that very same imaginative and prescient. And we predict it is actually price it to deliver all that innovation to Bitcoin.”
The workforce at BOB has highlighted three facets they consider are important for brand new layer 2 options to thrive:
1. A safety and financial alignment with Bitcoin
2. Infrastructure for the developer ecosystem to thrive
3. Liquidity to get new tasks off the bottom
“It’s about making a community the place liquidity and customers can seamlessly transition between tasks, enhancing the general vibrancy of the platform.”
Dom additionally elaborated on BOB’s market positioning: “Our method is kind of distinctive—we’re the one ones aiming to create what we name a hybrid L2.”
BOB’s rollup resolution is designed to be secured by Bitcoin whereas being built-in into the Bitcoin stack by means of light-weight purchasers. Concurrently, it additionally features as a rollup on Ethereum to facilitate ease of use for these throughout the Ethereum group. “Lots of people are used to bridging over from Ethereum to platforms like Arbitrum, Bays, or Optimism,” Dom acknowledged. This familiarity makes BOB a pretty platform for customers and builders from the Ethereum area, permitting them to leverage their current information and instruments seamlessly.
At the moment constructed on the OP Stack, the main target of the workforce thus far has been to make the person and developer expertise as native as attainable to Ethereum to cut back friction for brand new contributors. Dom additionally clarified that no trust-minimized bridges are at present obtainable to maneuver Bitcoin to the platform.
The BOB Roadmap
BOB intends to roll out its protocol in a collection of strategic phases designed to incrementally improve the platform’s capabilities:
Part One: Bootstrapping
Launched on Could 1st, this preliminary section focuses on establishing BOB as an optimistic Ethereum roll-up utilizing the OP stack, with out Bitcoin security measures built-in but.
Part Two: Integrating Bitcoin Proof of Work Safety
The subsequent step includes transitioning BOB to incorporate Bitcoin’s proof of labor safety utilizing Optimine, a merge mining protocol designed to harden the system’s safety.
Part Three: Transition to Bitcoin Rollup
This section goals to shift the platform from an Ethereum-based to a Bitcoin-based roll-up, contingent on the progress of latest applied sciences resembling BitVM and different fraud-proof schemes.
Part 4: Implementation of Zero-Data Proofs
The ultimate section anticipates integrating zero-knowledge proofs, pending Bitcoin’s potential adoption of the know-how. This may considerably improve privateness and transaction effectivity.
Growing OptiMine
The workforce’s present focus is to introduce “Optimistically Sequenced Merged Mining“, a brand new approach that begins the method of integrating Bitcoin’s safety into BOB. Dom explains, “OptiMine extends conventional merged mining by separating block manufacturing from proof-of-work finalization.” He argues it will permit the protocol to realize fast transaction processing whereas guaranteeing the integrity related sometimes with Bitcoin.
How OptiMine Enhances Safety and Effectivity
- Optimistic block manufacturing: Blocks are produced optimistically each two seconds by sequencers, guaranteeing the excessive throughput that builders from the Ethereum area are accustomed to. OptiMine improves transaction finality speeds, which is essential for person expertise. “In comparison with conventional merged mining strategies, OptiMine permits for faster finality, enhancing total system effectivity,” Dom provides.
- Bitcoin-secured finalization: In OptiMine, Bitcoin miners validate the blocks produced by sequencers by embedding a reference hash of the BOB blocks inside Bitcoin blocks, that are then added to the Bitcoin blockchain. This validation considerably reduces the hurt that comes from counting on centralized sequencers.
- Re-org resistance: By separating block manufacturing from proof-of-work, Optimine avoids the danger of a miner attacking the chain to rewrite its historical past.
- Merged Mining Effectivity: OptiMine makes use of Bitcoin’s current mining infrastructure to safe BOB’s rollups with out further vitality prices.
With the introduction of OptiMine and the strategic rollout of its growth phases, BOB’s mission is to unite two ecosystems to create a flexible platform that leverages the strengths of each other.
“We wish to primarily be the platform in between Bitcoin and Ethereum. And when you’ve got property from Ethereum, they need to have Ethereum safety. When you usher in property from Bitcoin, they need to have Bitcoin safety and you must be capable of use each on Bob.”
