Bitvmx for rootstock: What are the upcoming upgrades?

April 14th Bitvmx for rootstock: What are the upcoming upgrades?

Floorstock Blockchain Layer Platform 2 develops smart contracts and decentralized applications for Bitcoin networks. BITVMX is a major improvement for Bitcoin smart contracts. This allows for multi-purpose calculations of the base class without changing consensus rules. Developed from BITVM, BITVMX has a virtual CPU for running and verifying complex programs (such as zero knowledge proof) by confirming optimism (it is considered true unless there is a complaint), reducing the load on the blockchain. New points include using hash chains to check execution traces, linking messages to a single signature, and improving state efficiency and security through transactions. Rootstock’s upcoming SDK will help developers build second-tier applications (rollups, bridges, oracles) directly on Bitcoin. BITVMX opens more powerful smart contracts and is securely programmed and expanded into Bitcoin.

What is Bitcoin Smart Contract’s “superpower” BITVMX?

Bitvmx on Bitcoin’s Sidechain Rootstock Upgrading Bitvmx is a dramatic one, helping Bitcoin dance more games without touching on the core protocols. With the virtual CPU model, BITVMX uses CPU structures such as RISC-V to support complex calculations such as Snark. Optimistic verification methods require optimizing performance and scaling capabilities without causing risk to the base Bitcoin class only when testing is required.

A special feature of BITVMX is the Challenge Response Protocol using chains, which is much easier than using the old Merkle Tree. This method not only makes the machine softer, but also makes it easier to breathe by building a roll-up and sidechain in Bitcoin. Additionally, “attachment messages” using disposable digital signatures allow multiple “cooperation” and “communication” transactions, keeping everything “stable” through interactions on the blockchain. This “cool” design paved the way for a “flexible” based system like Ethereum, but Bitcoin scripting language doesn’t require a “machine.”

Rootstock’s SDK promises to provide developers with tools to build layer 2 solutions such as distributed bridges, optimistic rollups, and Oracle. Cooperation between rootstocks, fairgates, and input outputs (IOs) is also preparing infrastructure for future upgrades.

Does the “machine” internal BitVMX work?

BITVMX acts as a virtual computing environment, allowing complex programs to be executed and verified in the base class of Bitcoin through an optimistic verification model. Instead of performing all calculations on a chain, we assume that BITVMX is valid as long as it is not difficult to calculate. If there is a dispute, the traces are analyzed and the protocol challenge protocol is validated step by step.

Challenging protocols are key to the efficiency and security of BITVMX. Once the program is out of the chain, it creates a step-by-step diary of the calculated state. This trace is engraved on the chain, allowing for single step verification. If someone challenges validity, the system performs a binary search on the hash chain to determine a specific error. The calculation steps are then performed and verified directly in Bitcoin without disclosing the entire trace or using the Merkle tree as an earlier version.

To ensure secure communication between stakeholders, BitVMX introduces mechanisms to link messages using single-digit signatures, such as Lamport and Winteritz. This allows dependent transactions to be pre-signed in a chain, minimizing the risk of operations during dispute resolution (such as snark verification agents and cross-chain bridges).

What features can BitVMX users expect?

BITVMX expands Bitcoin’s programming capabilities without changing core consensus rules. This allows for more complex smart contracto. This was difficult or not done before Bitcoin.

One of the great features is the ability to directly verify non-knowledge evidence (ZKPS) with Bitcoin. This is a breakthrough in advanced security applications such as rollups and anonymous identity systems. Developers can compile ZK Proof Verifiers into BITVMX compatible code and check them in a chain. This opens up the possibilities of security tools, safety voting mechanisms, distributed identity systems, and extended roll-up layer 2.

BitVMX also supports the construction of distributed bridges and sidechain communication mechanisms. For example, Rootstock has developed the “Union Bridge” to create a low, reliable bridge between Bitcoin and its sidechain. These bridges use encryption and calculated evidence to ensure security, allowing for smooth interactions between Bitcoin and other blockchains like Cardano.

Additionally, BITVMX supports highly distributed applications such as complex financial contracts, decentralized Oracles, and even optical machine learning verification. BitVMX transforms Bitcoin from a secure digital currency into a powerful computing platform, expanding its utility while retaining a unique security model.

in short,: BitVMX is a true revolution for Bitcoin, turning it from a simple monetary system to a powerful computing platform. In addition to maintaining the inherent security of Bitcoin, BitVMX also opens up many new features such as rollups, decentralized bridges, and ZKP applications. This is an interesting time to discover the great potential of Bitcoin in the world of defi and blockchain!
