Configurable Bridge Deployment, Taproot Dual-Path Custody, and Multi-Proposal Governance

Configurable Bridge Deployment, Taproot Dual-Path Custody, and Multi-Proposal Governance

Via is a Bitcoin Layer 2 sovereign validity-proof zk-rollup. Anchored by commitments with a zkEVM execution layer using Celestia for data availability, and a distributed verifier network for proof validation. Delivering full EVM programmability with high throughput, cost efficiency, Bitcoin-anchored settlement with reorg-bounded finality, and end-user verifiability. The Via Network

Handling Large proofs on Celestia by chunking blobs

Handling Large proofs on Celestia by chunking blobs

We've been building the Via Network to post data to Celestia for Data Availability guarantees. We knew there were limits, and we would hit a hard wall. For us, that wall came when our proof data exceeded what we could safely post in a single operation. Here, we

From One‑Off Genesis to Live Governance: Treating Role Addresses as State in the Bitcoin Indexer

From One‑Off Genesis to Live Governance: Treating Role Addresses as State in the Bitcoin Indexer

We've moved Via's Bitcoin stack from a one-time "genesis import" to a live governance-driven state. System wallets (sequencer, verifiers, bridge, governance) are no longer hardcoded facts learned at startup. They're tracked as state, validated against on-chain inscriptions, and updated atomically at runtime.

Dynamic System Wallet Registry - 224

Dynamic System Wallet Registry - 224

Another major infrastructure upgrade to the Via L2 network. Due to this new upgrade, every part in the network, including sequencer addresses, verifier keys, bridge controllers, and governance wallets, is tied to governance-approved Bitcoin transactions, creating an immutable, queryable history of who had authority at any point in time. The

Zero-Downtime Governed Runtime: Taproot Key-Path + Script-Path

Zero-Downtime Governed Runtime: Taproot Key-Path + Script-Path

Major upgrade to Via L2 zkEVM Rollup bringing governed runtime updates and Taproot-powered resilience into production. * Governed wallet updates, applied live via Bitcoin events. * Database-backed, insert-only audit log with efficient “latest-by-role” reads. * Taproot + MuSig2 Bridge: private key-path spends, script-path fallback for recovery. * Zero downtime for rotations, upgrades, or incident response.

Verifier Network upgrade: State-aware validation & deterministic head selection

Verifier Network upgrade: State-aware validation & deterministic head selection

We've rolled out yet another major upgrade to the Via Verifier Network, which makes chain progression more reliable under load while reducing network overhead by half during batch ingestion. The upgrade also strengthens chain integrity and closes a subtle TOCTOU window, which makes head selection deterministic. TL;DR

Verifier Network Upgrade: Faster Deterministic Finality

Verifier Network Upgrade: Faster Deterministic Finality

We've rolled out an upgrade patch for deterministic finality, lower memory, and faster verification for the Via Verifier Network. As we fixed a subtle consensus edge case in our verifier network: duplicate canonical batches We've introduced partial unique indexes in PostgreSQL to enforce a key rule
