⚡ Sub-Second Finality Is Coming to TON

TON Core is upgrading the blockchain to significantly increase block production speed, targeting sub-second user-perceived transaction finality, enabling end-to-end interactions in under 1 second.

Improving the blockchain is only part of the upgrade. Ecosystem apps need to adapt to deliver this experience to users.

Developers can start testing now and prepare for the upgrade.

What projects should do
🔹 Wallets & apps: switch to real-time Streaming API
🔹 Nodes & liteservers: update to versions supporting sub-second transaction finality
🔹 Indexers: ensure infrastructure handles higher block production without lag

📘 Full upgrade guide: How to adopt sub-second finality

💎Tolk v1.3 is here, and it’s no longer just a smart contract language

Tolk is evolving into a general-purpose language and a foundation for a broader TON development toolchain. This release introduces capabilities needed for libraries, frameworks, and developer tools beyond contracts.

The TON Core team is moving full speed to rethink the developer experience from the ground up.

Big updates are on the way, and more details will be shared soon.

Building on TON has never been this easy. And we are just getting started.

🚀 The AI Hackathon review period has been extended until April 3.

The results exceeded all expectations: over 160 submissions, 4x the previous contest.

The volume and variety of projects submitted have genuinely impressed us. A strong mix of thoughtful, creative, and technically impressive work from across the ecosystem.

We definitely didn’t expect that. So, we are extending the review period to April 3 to ensure we have enough time to review every submission thoroughly.

While you wait, two new features just dropped on the Identity platform:

🔹Makers. Add your teammates to submission. Everyone gets the participation badge.
🔹Comments. Talk about projects. Feedback, questions, discussion, all on submission pages.

Thank you for the energy, creativity, and effort you brought to this hackathon.

Keep building! ✨😎

Identity is the trust layer for the TON ecosystem.💎

It turns public ecosystem activity into reputation by analyzing signals such as code, wallets, badges, and social presence, helping make contribution and credibility more visible across TON.

Now Identity has released Launches, a new discovery section for products building in the ecosystem.

✨ The first Launches cohort is now live with 16 projects
How it works:
• users clap for the projects they like
• clap budget is tied to Identity reputation
• top projects earn permanent badges on Identity at the end of the week

This makes discovery more transparent and gives more weight to real ecosystem contribution.

✨ Projects in the first cohort include:
• OmniMarket — prediction markets for Telegram communities
• EdChess — play chess and earn TON
• Toncenter SDK — AI-ready Python SDK for TON
• TON Agent Platform — no-code AI agents in Telegram
• TON Bridge — cross-chain liquidity for TON
• ENACT Protocol — on-chain escrow for AI agent payments
• Catallaxy — decentralized agents marketplace
• TeleGifts — AI-powered Telegram Gifts analytics and swaps
• Hash2Cash — Bitcoin mining based on RWA
• ODROB — financial layer for agents
• Rolls — PvP game with Telegram NFT gifts
• mena — P2P atomic asset exchange on TON
• Swift Gifts — Telegram Gifts aggregator
• TonGo — .ton DNS lookup service
• Watchi — AI focus coach with streaks and ambient sounds
• MOLVA — social game on TON

👉 Check out the cohort and vote for your favorites
⚡Rankings close on Sunday.

Catchain 2.0 activation is underway

TON validators are voting to fully activate Catchain 2.0, a consensus upgrade that brings sub-second finality to the network.

The first phase has been live since April 2. Today, at 14:00 UTC, the final vote started to cut block times to 400 ms across the entire network.

To activate the upgrade, validators vote on-chain. The proposal needs support from at least 75% of validators (by stake weight) across two validation rounds, roughly 36 hours.

Blockchain Fee Reduction

The TON Core team has prepared a blockchain update to reduce fees by 6x, in line with Pavel Durov’s MTONGA plan.

This update includes:

1) Performance improvements

The previous Sub-Second update improved not only operation speed but also overall blockchain performance, making a fee reduction possible. Since then, additional optimizations and performance improvements have also been implemented, including a new mempool based on a persistent Cartesian tree.

2) Fixes

In addition to performance improvements, this update will include fixes for issues identified on mainnet after the Sub-Second release. In particular, it addresses loss of synchronization on some liteservers and rare block rate instability.

Planned Schedule:

April 28, 2026 12:00 UTC — Validator software update.
April 30, 2026 13:00 UTC — Vote to lower gas prices in the blockchain configuration.

Lower fees are important for the next stages of the MTONGA plan. Since fees do not constitute a significant portion of validator rewards, validator rewards are expected to decrease by less than 0.4%.

Mainnet validator operators are asked to be prepared to update their software on 28 April and to participate in the vote on 30 April.

Voting by validators on reducing network fees has begun

Validators, please participate in the vote.

Introducing Acton — a new, modern toolchain for developing smart contracts on TON

Acton covers the full development lifecycle: project creation, testing, debugging, dApp integration, deployment, and verification.

CLI-first by design, it works naturally for both developers and AI agents.

1. One toolchain, not a bunch of utilities
Create, build, test, lint, format, deploy, and verify TON contracts in a single coherent environment around Tolk.

2. A tighter build-test-debug loop
Write tests directly in Tolk programming language, run them fast, debug failed transactions, and inspect what actually happened on-chain.

3. Security built in
Coverage, fuzzing, mutation testing, gas profiling, and CI help catch regressions early.

4. A native debugger
Step in, step over, step out, watch variables, and inspect the call stack. A smooth Web2-style developer experience, now inside a blockchain language.

5. Friendly for AI agents
A modern CLI tool that becomes an agent's runtime, with skills and manuals bundled.

6. IDE integtation
Use it with VS Code, JetBrains, Cursor, Zed, and other LSP‑based editors.
