Project Lightspeed: Instant Finality Upgrade

Telos is upgrading the part of the network that decides when a transaction is truly done.

Instant Finality is the second pillar of Project Lightspeed, the coordinated infrastructure upgrade program for the Telos network.

TelosZero Core gives the network the base. Instant Finality upgrades the confidence layer. TelosEVM 3.0 brings that infrastructure story to Solidity developers and the EVM ecosystem.

Why Finality Matters

A blockchain can produce blocks quickly while still requiring users, apps, bridges, and exchanges to wait for stronger assurance that a transaction will not be reorganized. Finality is the point where that assurance becomes part of the protocol outcome.

For users, faster finality means faster confidence. For builders and infrastructure providers, it means a clearer settlement signal for payments, swaps, bridges, indexers, custodians, games, and privacy applications that need to know when a transaction is complete.

What The Upgrade Changes

The Instant Finality phase moves Telos toward a modern finality model based on the Savanna consensus work introduced in Antelope Spring and carried forward through TelosZero Core.

In practical terms, this upgrade is about more than making the chain feel faster. It strengthens the trust model around final settlement so that applications can reduce waiting periods, improve user flows, and build around a more reliable confirmation layer.

• Faster confidence that transactions are final
• A stronger settlement layer for exchanges, bridges, wallets, and applications
• Better infrastructure foundations for privacy and cross-chain workflows
• A clearer path for Telos-specific protocol upgrades through TelosZero Core

Built For Operators And Builders

Instant Finality depends on coordinated network readiness. Block producers and infrastructure operators need to run the correct node software, prepare finalizer configuration, and follow the upgrade path defined for the Telos network.

For builders, the result is a better base layer to build on. Applications that rely on transaction certainty can design around faster finality instead of adding extra waiting time to protect against uncertainty.

Why It Matters For Privacy

Privacy applications are especially sensitive to finality. Private transfers, shielded balances, bridging flows, and future zero-knowledge workflows need strong settlement guarantees before downstream systems act on a transaction.

By upgrading the confidence layer, Telos gives privacy infrastructure a stronger foundation. That matters for users who want private activity to feel fast without weakening the security assumptions behind it.

Part Of Project Lightspeed

Project Lightspeed brings together three major infrastructure milestones: TelosZero Core, Instant Finality, and TelosEVM 3.0.

Together, these upgrades move Telos toward a more operator-controlled, developer-ready, and settlement-focused network stack. TelosZero Core establishes the maintained core software base, Instant Finality strengthens confidence in transaction settlement, and TelosEVM 3.0 brings the next phase of that work to EVM builders.
