TON (The Open Network) released its Catchain 2.0 consensus upgrade and cut block time to 400 milliseconds. Previously, transactions on the network took around 10 seconds to settle. Payment transfers now clear in about 1 second, trading happens in real time, and decentralized applications run at speeds comparable to standard mobile apps.
What changed in the protocol
Catchain 2.0 builds on the original Catchain consensus algorithm first proposed in 2020. The upgrade moves TON into the group of blockchains with sub-second transaction finality. Payment operations now settle in about 1 second. Trades on decentralized platforms execute in real time without the delays that previously made a simple swap take several seconds.
A 400ms block time puts Toncoin in the same category as the fastest public blockchains. Ethereum confirms transactions in 12 seconds and relies on Layer 2 solutions for speed. Solana targets 400ms at the base layer. TON now competes at that level without requiring developers or users to migrate to sidechains or rollups.
More blocks, more validator rewards
Each block added to the chain carries a validator reward. Higher block frequency means more staking payouts. The TON team expects this to attract new node operators and strengthen network decentralization.
There is a trade-off, though. Annual Toncoin inflation will increase roughly six times, from about 0.6% to 3.6%. New tokens are minted as validator rewards while a portion is burned through the network's burn mechanism. For long-term holders, the key question is whether transaction volume grows fast enough to offset the expanded supply.
The market reacted modestly on the day of the upgrade. TON gained 2.3% to $1.28 with $130 million in trading volume, up 35% from average. Network market cap stands at $3.17 billion.
Why speed matters for Telegram's billion users
Telegram users can already send crypto inside the app through Wallet. But when a transaction takes 10 seconds, the experience feels slower than a regular bank transfer. At 1-second settlement, the gap between a crypto payment and a standard transfer becomes barely noticeable to an average user.
Pavel Durov noted that government attempts to block Telegram in Iran and Russia have failed, with users turning to VPNs. For Wallet's crypto features, that means the real user base extends well beyond official numbers. Even a small share of Telegram's billion users adopting crypto payments would represent tens of millions of transactions.
Catchain 2.0 in the context of Telegram Wallet growth
In February 2026, Telegram Wallet launched self-custodial vaults offering yield on Bitcoin, USDT and Ethereum. Earlier this month, perpetual futures trading went live through the Lighter platform, covering crypto, equities and commodities. Catchain 2.0 provides the technical foundation for these products: real-time futures trading is far more practical at 400ms block times than at 10 seconds.
TON is building toward becoming the financial layer for Telegram. What started as a collection of separate crypto features is taking shape as a complete financial infrastructure inside the world's largest independent messaging app. Catchain 2.0 makes that infrastructure technically competitive.
Takeaway
10 seconds was too slow for messenger payments. 400ms is workable. Catchain 2.0 removes the main technical weakness of TON and opens the door for real use in DeFi and Telegram Wallet. The price moved modestly - markets often price in technical upgrades with a delay, once new features start pulling in developers and activity. The upgrade is done. The next measure is whether network usage grows fast enough to justify the higher inflation.
