When we started with Viacoin in 2014, we knew that we are not going to just stop there. We didn’t want to create just another crypto project using Bitcoin’s consensus - we wanted to build something more meaningful on top of Bitcoin. To do that, we focused on the
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-
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
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
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.
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
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
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
We’ve upgraded Via’s verifier selection logic to eliminate race-condition forks and drastically improve performance. Part of Patch 221 hardens canonical chain selection by replacing correlated SQL subqueries with a CTE that finds the canonical chain tip in O(log n) time (instead of O(n²)) and prevents
Via is a Bitcoin Layer 2 Modular Sovereign ZK-Rollup that combines zero-knowledge proofs, zkEVM, Bitcoin's PoW security, and Celestia data availability layer by adopting a modular approach without compromises. Users can pay gas fees in Bitcoin while using Via. Quick introduction Via processes thousands of transactions
Via L2 is the culmination of everything we learned from 2014 over the past decade, incorporating ideas from multiple designs, Layer 1s, rollups, and early Bitcoin networks, such as Mastercoin, Counterparty, and Clearinghouse. Over the years, we've seen the rise of competing alt Layer 1 chains. Each new
A complete introduction to Via, including its origins, history, technology, vision, design rationale, and revenue model The original Viacoin was a cryptocurrency that supported embedded consensus with an extended OP_RETURN of 120 bytes. Embedded consensus is a design method for building layer-2 logic on top of Bitcoin without
