Pavel Durov posted a chart this week that is worth looking at twice. According to Chainspect’s May 2026 data, TON sits at 0.6 seconds to finality, beating Avalanche (1 sec), BNB Smart Chain (1.1 sec), SUI (1.5 sec), Hedera (2.5 sec), XRP Ledger (4 sec), and Solana (13 sec). Bitcoin and Ethereum do not even appear competitive on this metric, sitting at 1 hour and 13 minutes respectively.
Why Now
The timing of Durov’s post is not random. In April, TON deployed its Catchain 2.0 consensus upgrade, cutting block times from roughly 2.5 seconds down to 400 milliseconds and boosting throughput by an estimated 10x. Settlement times dropped from around 10 seconds to approximately 1 second.
Payment transactions now settle in about 1 second, trades settle in what TON describes as real time, and decentralized applications are now operating at speeds comparable to traditional apps. That last part is the more interesting claim. Consumer fintech lives and dies by perceived latency, and 0.6 seconds is approaching the threshold where users stop noticing the blockchain underneath.
The Upgrade Has a Cost
Faster block times produce more validator rewards as the number of blocks added to the chain increases. TON’s annual inflation is projected to increase sixfold, to 3.6% from about 0.6% following the update. That is a meaningful trade-off, and one that does not get mentioned in a tweet with a bar chart.
Where TON’s Real Advantage Sits
The distribution argument is where TON’s case gets more serious than the speed numbers alone suggest. The chain is housed inside Telegram, a messaging application with over a billion users. Wallet creation, payments, and mini-apps now operate within a chat interface that hundreds of millions of people use daily. No other chain in this finality comparison can make that claim.
Solana has the developer ecosystem. SUI has the architecture pedigree. TON has the install base. In a race for consumer-grade blockchain, that could end up being the deciding factor.
What the Chart Does Not Show
Independent rankings tell a slightly more competitive story at the top. Chainspect confirms that SUI delivers finality that is a meaningful differentiator for financial applications where settlement certainty is operationally critical. Durov’s data puts TON ahead of SUI at 1.5 seconds, but independent analysts do not give such a clear gap at the top of the table.
The Broader Picture: The Gap Is Closing
There is a growing sense across the industry that the days of significant speed disparities between major blockchains are coming to an end. Distribution, developer experience, and ecosystem depth rather than raw throughput will increasingly determine which chains win.
By that logic, the bar chart helps TON’s story more than it tells it. Sitting at the top of a finality ranking matters less than what gets built on a chain once it can credibly claim the top spot. The next few quarters will show whether Catchain 2.0 brought developers along with it, or just gave Durov a good chart to post.
