Proof System Migration & Upgrading

Seamlessly migrate from legacy proof systems (e.g., PoW, PoA) to modern, scalable alternatives like zk-SNARKs, zk-STARKs, or PoS. We handle the cryptographic transition, validator set orchestration, and state synchronization.

Upgrade your network's consensus mechanism (e.g., from Tendermint to CometBFT, or custom BFT variants) with rigorous testing and validator coordination to maintain liveness and security.

Port dApps and core logic between virtual machines (EVM → SVM, EVM L1 → L2) or upgrade contract architectures with comprehensive testing and state migration tooling.

Implement secure, trust-minimized bridges (canonical, optimistic, zk) during migrations to ensure asset portability and maintain composability with the broader ecosystem.

Manage the entire upgrade lifecycle: from governance proposal drafting and community signaling to on-chain execution and post-upgrade monitoring, ensuring smooth stakeholder transitions.

Every migration includes a final security review by our in-house auditors, checking for new attack vectors, economic assumptions, and integration flaws to guarantee system robustness.

We implement proven blue-green deployment and state synchronization patterns to ensure your application remains live and responsive throughout the entire migration process, eliminating revenue loss and user disruption.

Our engineers have performed production migrations for ZK-SNARKs (Groth16, Plonk), ZK-STARKs, and Optimistic Rollups. We handle the intricacies of circuit upgrades, verifier contracts, and proving key management.

Every migration plan includes a formal security review, differential testing against the legacy system, and a final audit of the new verifier logic and upgrade mechanisms before go-live.

We provide a detailed project plan with phased deliverables, from audit and staging to final cutover. Our fixed-scope engagements eliminate budget overruns and ensure on-time delivery.

We conduct a comprehensive audit of your current system, identifying dependencies, state management, and potential migration risks. This includes a detailed security review and a rollback strategy.

We deploy and configure the new proof system (e.g., zkEVM, STARK) in a staging environment that mirrors production. This allows for exhaustive testing and validation before any live cutover.

We implement a real-time state synchronization bridge between the old and new systems. Every transaction and proof is validated for consistency, ensuring no data loss or double-spend scenarios.

Using canary deployments and feature flags, we redirect user traffic from the legacy system to the upgraded one in controlled batches. Performance and correctness are monitored at each increment.

After full cutover, we monitor system performance, optimize proof generation times, and fine-tune parameters. We provide a full audit report and handover documentation.

Our process is built on formal verification principles and security-first design. All migrations include a final audit by our internal security team, adhering to industry standards.
