Bitcoin & Past is an academic collection by the staff at The Rollup targeted on a brand new and rising class of builders within the Bitcoin ecosystem. By areas, panels, and interactive shows, the target is to offer deep technical insights into modern scaling tasks.
In our newest function 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 By Layer 2 Options
From the onset, Dom was clear that BOB’s main motivation has been “to make it rather a lot simpler for folks to construct on Bitcoin.” He highlighted the huge alternative for Bitcoin to develop 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 presently 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 value it to convey all that innovation to Bitcoin.”
The staff at BOB has highlighted three points they imagine are important for brand spanking 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 strategy 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 gorgeous platform for customers and builders from the Ethereum house, permitting them to leverage their current information and instruments seamlessly.
At the moment constructed on the OP Stack, the main focus of the staff to this point has been to make the person and developer expertise as native as potential to Ethereum to cut back friction for brand spanking new members. Dom additionally clarified that no trust-minimized bridges are presently accessible 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:
Section One: Bootstrapping
Launched on Might 1st, this preliminary part focuses on establishing BOB as an optimistic Ethereum roll-up utilizing the OP stack, with out Bitcoin security measures built-in but.
Section Two: Integrating Bitcoin Proof of Work Safety
The subsequent step entails transitioning BOB to incorporate Bitcoin’s proof of labor safety utilizing Optimine, a merge mining protocol designed to harden the system’s safety.
Section 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 latest applied sciences comparable to BitVM and different fraud-proof schemes.
Section 4: Implementation of Zero-Information Proofs
The ultimate part anticipates integrating zero-knowledge proofs, pending Bitcoin’s potential adoption of the expertise. This is able to considerably improve privateness and transaction effectivity.
Growing OptiMine
The staff’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 it will enable 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 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.
- 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 extra 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 wish to primarily be the platform in between Bitcoin and Ethereum. And you probably have property from Ethereum, they need to have Ethereum safety. In the event you herald property from Bitcoin, they need to have Bitcoin safety and it’s best to be capable to use each on Bob.”
