Introducing Ziren (formerly zkMIPS) The most performant general-purpose zkVM on CPU, now scaled with GPU, distributed proving, and more. Build with confidence. Deploy without compromise 🟠 Full context: Technical updates:

For years, ZK promised to transform every layer of blockchain, but most developers couldn’t use it. It required writing circuits manually, using domain-specific languages, and dealing with overhead that made real deployment impractical.

zkVMs were introduced to change that. But most were built on sub-optimal foundations, using ISAs like RISC-V which is well-suited for embedded hardware, but not zero-knowledge efficiency. The result: systems that function, but inherently compromise on performance.

Enter Ziren (formerly zkMIPS) - the fully-scalable evolution of ZKM’s zkVM stack. Ziren is built for real-world use cases, with GPU acceleration, constraint system optimizations, and a distributed network prover.

It compiles standard languages like Rust, C, and Go into a MIPS-based instruction format specifically suited to zero-knowledge systems, with every component of the stack optimized for circuit efficiency and scalability. The outcome: developers can build normal applications with zero-knowledge guarantees, on top of a stable foundation, without needing to touch custom circuits or cryptographic logic.

Already proven as the fastest general-purpose zkVM on CPU, Ziren’s proving engine is now GPU-accelerated, yielding major improvements in latency and throughput. Core proofs now generate up to 30× faster, with wrap and aggregation stages similarly optimized.

This performance is extended further by a distributed Network Prover, which parallelizes computation across nodes and ensures fault-tolerant proving pipelines. Together, this forms a highly scalable proving backend deployable in modular rollup or serverless environments.

Ziren's constraint system has been restructured around modular chips. CPU logic, memory access, branching, and jumps are separated and streamlined, minimizing redundant columns and improving execution trace clarity. The payoff is both quantitative and architectural: faster proofs, reduced overhead, and clearer debugging and auditability for application developers.

Where most zkVMs adopt RISC-V by default, Ziren uses MIPS - an ISA whose characteristics better align with the needs of circuit construction. Fixed 32-bit instruction width, low-entropy encoding, dense opcodes, and ISA stability simplify decode logic and reduce the circuit complexity of proof generation. It’s the more difficult path to implement from the standpoint of building a zkVM, but the better long-term foundation for ZK, offering developers an application base they can rely on. Deep dive:

Ziren supports common workflows out-of-the-box. Developers write Rust, C/C++, or Go, compile through Ziren’s patched LLVM toolchain, and get end-to-end verifiable output. This removes the need for DSLs, circuit fiddling, or external plugins - and makes it possible to build Bitcoin rollup applications with ZK backends, multi-chain apps that rely on recursive proof generation for trust-minimized coordination, and much more.

Ziren already powers new infrastructure models like @GOATRollup’s Bitcoin-native rollup. By verifying proofs natively on different chains, Ziren replaces message-passing bridges with shared cryptographic state. Proofs are generated recursively and verified without centralized verification dependencies. The result is an architecture capable of real finality and verifiable interoperability between chains like Bitcoin and @ethereum.

Recent updates to @eth_proofs demonstrate the practical advances enabled by Ziren. By swapping the guest VM from Revm to Reth and optimizing the block/state preparation layer using debug_traceBlock and parallel account fetching, we reduced state preparation time from over 5 minutes to under 30 seconds - more than doubling total throughput and moving closer to real-time proving.

Ziren is more than a zkVM. It’s a complete zero-knowledge execution environment - optimized at every layer for performance, composability, and developer usability.
