Bridging Bitcoin & Ethereum: BOB’s Hybrid Layer Two Solution

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. Via areas, panels, and interactive displays, the target is to supply deep technical insights into modern scaling initiatives.

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 know BOB’s staged strategy to growth and their new merged-mining protocol, Optimine. 

Reigniting Innovation in Bitcoin Via Layer 2 Options

From the onset, Dom was clear that BOB’s major motivation has been “to make it lots simpler for individuals to construct on Bitcoin.” He highlighted the large alternative for Bitcoin to turn into as simply programmable as Ethereum whereas sustaining the strong safety it’s identified for.

Like many others, he echoed his appreciation for this wave of innovation at the moment energizing the Bitcoin ecosystem. “There are such a lot of new initiatives now sharing that very same imaginative and prescient. And we predict it is actually value it to deliver all that innovation to Bitcoin.”

The workforce at BOB has highlighted three points they imagine 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 initiatives off the bottom

“It’s about making a community the place liquidity and customers can seamlessly transition between initiatives, enhancing the general vibrancy of the platform.”

Dom additionally elaborated on BOB’s market positioning: “Our strategy is sort 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 via light-weight shoppers. Concurrently, it additionally capabilities as a rollup on Ethereum to facilitate ease of use for these inside 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 sexy platform for customers and builders from the Ethereum house, permitting them to leverage their current data and instruments seamlessly.

At present 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 the moment out there 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 part focuses on establishing BOB as an optimistic Ethereum roll-up utilizing the OP stack, with out Bitcoin safety features built-in but.

Part Two: Integrating Bitcoin Proof of Work Safety

The following 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 part goals to shift the platform from an Ethereum-based to a Bitcoin-based roll-up, contingent on the progress of recent applied sciences resembling BitVM and different fraud-proof schemes.

Part 4: Implementation of Zero-Information Proofs

The ultimate part anticipates integrating zero-knowledge proofs, pending Bitcoin’s potential adoption of the expertise. This could considerably improve privateness and transaction effectivity.

Growing OptiMine

The workforce’s present focus is to introduce “Optimistically Sequenced Merged Mining”, a brand new method 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 this can permit the protocol to realize speedy transaction processing whereas guaranteeing the integrity related usually with Bitcoin.

How OptiMine Enhances Safety and Effectivity

1. Optimistic block manufacturing: Blocks are produced optimistically each two seconds by sequencers, guaranteeing the excessive throughput that builders from the Ethereum house 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 general system effectivity,” Dom provides.
2. 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.
3. Re-org resistance: By separating block manufacturing from proof-of-work, Optimine avoids the chance of a miner attacking the chain to rewrite its historical past.
4. Merged Mining Effectivity: OptiMine makes use of Bitcoin’s current mining infrastructure to safe BOB’s rollups with out further power 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 need to basically be the platform in between Bitcoin and Ethereum. And in case you have property from Ethereum, they need to have Ethereum safety. When you herald property from Bitcoin, they need to have Bitcoin safety and you need to be capable to use each on Bob.”
