TON Mainnet Sub-Second Upgrade Is Now Live: On-Chain Payments and Gaming Scenarios Will See Structural Changes

In April 2026, The Open Network saw the most meaningful performance upgrade since the mainnet went live. The TON core team announced a consensus mechanism upgrade, Catchain 2.0—i.e., the Sub-Second upgrade—has entered the final stage of mainnet deployment, and completed full activation on April 7. This upgrade compresses the block finalization time from the current roughly 10 seconds to about 1 second, and shortens the block interval from about 2.5 seconds to 200-400 milliseconds.

As public-chain competition increasingly focuses on “who can carry real-world applications,” TON has secured a unique advantage of user scale thanks to its deep integration with Telegram. Whether this sub-second upgrade can truly unlock the potential of that user pool depends on dual momentum: technical deployment and ecosystem adaptation. This article will provide a systematic analysis of the upgrade’s technical substance, ecosystem coordination progress, market feedback, and evolution paths across multiple scenarios.

Event Overview

As of March 31, 2026, The Open Network (TON) has begun deploying the Sub-Second upgrade on its mainnet. This upgrade is an update aimed at the consensus layer, designed to achieve sub-second confirmation times and improve on-chain responsiveness. At the same time, infrastructure provider Dynamic has added embedded wallet capabilities, enabling developers to automatically deploy TON wallets into Telegram mini apps without building their own custom wallet systems.

This upgrade follows a strict phased deployment schedule:

• March 31: Validator node updates completed, upgraded to the latest version supporting Catchain 2.0
• April 2: Validator votes activated the new consensus mechanism on the base chain and increased block production frequency
• April 7: Full activation of the fast consensus mechanism on both the base chain and main chain

At the time of writing this article, the upgrade has completed full activation as planned. Toncoin, the token, shows on Gate market data that as of April 8, 2026, the trading price is approximately $1.23.

Consensus-Layer Restructuring Details and Performance Metrics Jump

Catchain 2.0’s Performance Leap

The core of the Sub-Second upgrade is the deployment of the consensus-layer protocol Catchain 2.0. Unlike simple parameter tuning, this upgrade involves a restructuring of TON’s underlying consensus mechanism.

From a performance metrics perspective, the changes before and after the upgrade are significant. Currently, the mainnet block interval is about 2.5 seconds, processing about 0.4 blocks per second, with finality lag of about 10 seconds; on the testnet in the Catchain 2.0 environment, block intervals of about 450 milliseconds and finality of 1-2 seconds have been achieved. The post-upgrade mainnet target is to further compress the block interval to 200-400 milliseconds, process 2.5-5 blocks per second, and control finality to about 1 second.

TON Center has also released Streaming API v2, providing push-based transaction status updates, with latency from on-chain events to clients that can be controlled to 30-100 milliseconds. MyTonWallet and tonscan.org have been the first to adopt this API; even before sub-second confirmations were enabled on the mainnet, these products’ transaction response times have already been reduced by nearly half.

The Essence of Throughput vs. Finality

TON’s original infinite sharding architecture provides theoretical high throughput—during a public test in October 2023, TON reached a peak of 104,715 transactions per second and earned a Guinness World Records certification under Certik supervision. However, there is a key difference between throughput capacity and actual confirmation speed: high throughput guarantees the network’s ability to carry large-scale transactions, while sub-second finality solves the time cost of each individual transaction from being sent to becoming irreversible. The latter has a more direct impact on user experience, and is the core value of this upgrade.

Worth noting is that in a technical announcement, TON’s official team specifically highlights a critical blind spot: even if the underlying blockchain generates blocks at nearly 10x speed, if projects continue using HTTP polling instead of the Streaming API, the transaction-status update latency in the user interface may still exceed 10 seconds. For example, with HTTP polling, after users click “send,” the transaction is included in a sharded block in about 0.4 seconds and submitted to the main chain in 0.8 seconds, but the UI update must wait for the next polling request, potentially delaying it by more than 10 seconds. After switching to Streaming API v2, the entire process can be completed within 1 second. This technical detail reveals the real constraint of the performance upgrade: consensus-layer optimization must advance in parallel with front-end adaptation; otherwise, users will not perceive any change in experience.

Ecosystem Infrastructure Co-Evolution and On-Chain Scale Observations

Wallet Infrastructure and Payment Tooling Improvement

The Sub-Second upgrade is not an isolated event. In Q1 2026, TON’s ecosystem infrastructure layer underwent a round of systematic strengthening.

On the wallet layer, infrastructure provider Dynamic (acquired by Fireblocks in October 2025) has added embedded wallet capabilities for TON, allowing developers to programmatically generate and manage user wallets inside Telegram mini apps. This integration, via Fireblocks’ hosted and compliance systems, unifies wallet deployment, transaction management, and asset security into a single technical stack. Nikola Plecas, Vice President for Payments at the TON Foundation, said that Telegram is becoming an important distribution layer for financial experiences, while TON provides the infrastructure layer. The launch targets over 1 billion Telegram users.

On the payment tooling layer, in February 2026 TON introduced TON Pay, a payment software development kit that enables merchants and mini-app developers to accept cryptocurrencies without having to manage wallet infrastructure or settlement systems. In the same month, TON Wallet added vault functionality, allowing users to hold, send, and earn returns on multiple assets directly within the chat interface.

On-Chain Ecosystem Scale Indicators

As of early April 2026, TON had activated more than 52.1 million wallets on-chain, and on-chain stablecoins exceeding $500 million. From a macro perspective, in the first half of 2025 Telegram generated $870 million in revenue, of which about $300 million is related to Toncoin’s exclusive protocol. These figures show that the synergy between TON and Telegram has moved from the technical planning phase into a substantive stage of commercial conversion.

Secondary Market Reaction and Split Opinions Analysis

The Typical Pattern of “Good News Sold Out”

Although the network upgrade is proceeding smoothly on the technical front, Toncoin’s price performance shows a clear “good news sold out” characteristic. As of April 8, 2026, based on Gate market data, Toncoin trades at around $1.23. On April 7, when the upgrade was fully activated, the token price fell by about 2.5%, indicating short-term selling pressure after market expectations were realized.

Consensus Amid Disagreement

Current market sentiment around TON is polarized. The optimistic side emphasizes the support this upgrade provides for the ecosystem’s long-term value—sub-second finality gives TON the ability to directly compete with high-performance public chains like Solana in high-frequency scenarios such as instant payments and on-chain gaming. The pessimistic side focuses on the weak token-price performance in the face of technical positives, arguing that the market has already priced in the upgrade expectations and that the short-term price lacks catalysts.

On-chain analysts point out that the price drop suggests traders may be participating in a “good news sold out” event—a common pattern where an asset’s price falls after widely expected positive events occur. From a technical perspective, Toncoin’s current trading price is below a key short-term resistance level of $1.34; this price point has struggled to break through effectively over the past few weeks.

The Decoupling Logic Between Price and Fundamentals

It’s important to clearly distinguish that price performance does not have a linear relationship with technical progress. A successful upgrade may increase TON’s scalability, potentially attracting more decentralized applications and users from among Telegram’s large user base, thereby supporting its long-term value. However, the current price trend mainly reflects short-term speculative pressure, and the market has already digested the expected gains from the upgrade. Historical experience suggests that the value release of public-chain infrastructure upgrades often lags behind the time when the upgrade is completed; the real effects need to be observed in changes in subsequent network activity and developer adoption rates.

Breakthroughs in Real-Time Scenarios and Shifts in Competitive Landscape

Structural Breakthrough in Instant Payment Scenarios

Sub-second finality’s value to blockchain applications is not simply “faster.” It enables usage scenarios that were previously impossible due to latency issues. In offline consumption scenarios such as coffee shops and convenience stores, a 10-second confirmation wait has already become a clear friction cost. Sub-second confirmation brings on-chain payments closer to the experience of card swiping or QR scanning, making TON viable as an alternative to traditional payment methods for small-ticket payment scenarios within the Telegram ecosystem.

On-Chain Gaming and Mini-App Interaction Efficiency

High-frequency interactions in GameFi and Telegram mini apps are extremely sensitive to latency. Previously, each on-chain operation required waiting for several seconds to receive a response, and users would clearly perceive “lag.” After the upgrade, in-game operations such as asset transfers, reward claims, and match settlement can provide feedback that is nearly real-time. This change may boost engagement in lightweight on-chain games within the TON ecosystem, but only if developers complete the Streaming API v2 adaptation work.

Positioning Shifts in Public-Chain Competition

This upgrade pushes TON into the same tier as high-performance public chains such as Solana in terms of performance. However, TON’s differentiating advantage lies in its binding to Telegram’s user scale—Telegram’s potential conversion space of over 1 billion monthly active users is a structural advantage that other chains can’t easily replicate. The sub-second upgrade addresses the question of whether “the on-chain experience can retain users,” while Telegram addresses “where users come from.” How fully the two align will gradually become evident over the next 6 to 12 months.

Risk Exposure Review and Multi-Scenario Evolution Projections

Known Risk Exposures

First, the long-term stability of the Catchain 2.0 consensus mechanism has not yet been sufficiently validated through a large-scale mainnet environment. The TON core team specifically warns that within the two-week period from March 31 to April 12, validators must maintain high operational vigilance to handle potential abnormal situations. This arrangement reflects the complexity of the consensus-layer upgrade—uncertainty still exists in real operation on mainnet even after testnet verification.

Second, delayed adaptation at the application layer may become a bottleneck constraining the upgrade’s effectiveness. TON’s official team clearly warns that if applications cannot be adapted, even if the underlying system is operating normally, the upgrade will appear ineffective.

Third, the problem of highly concentrated token holdings still exists. Wallet cluster analysis finds that about 85.8% of the supply is controlled by affiliated entities, directly resulting in highly concentrated governance power. This structural issue creates tension with the network’s long-term goal of decentralization.

Multi-Scenario Evolution Paths

Scenario 1: Smooth rollout and ecosystem coordination

The upgrade completes smoothly on April 7 with no major technical failures. Major ecosystem projects complete Streaming API v2 adaptation within 4 to 8 weeks, and users genuinely perceive the sub-second transaction confirmation experience in Telegram mini apps. On-chain activity gradually recovers over the 2 to 3 months after the upgrade, and there will be noticeable growth in stablecoin transfer volume and daily active users for game-type applications.

Scenario 2: Technical stability but delayed ecosystem adaptation

The consensus-layer upgrade succeeds technically, but application-layer adaptation lags behind expectations. Users still experience noticeable transaction delays in mini apps, preventing the technical benefits from effectively translating into end-user experience. Market expectations for TON shift from “a performance chain” to “still to be observed,” and the token price lacks a clear upward driver.

Scenario 3: Anomalies during deployment

During the observation period from April 7 to April 12, consensus anomalies or network instability occur. Referring to historical experience from 2025, when validator consensus was lost due to abnormal load, such events may trigger short-term market concerns. However, considering this upgrade has already run for a long time on the testnet, and it uses a phased deployment strategy, the probability of a comprehensive failure is relatively low.

Scenario 4: Persistent decoupling between price and fundamentals

Even if the upgrade goes smoothly and ecosystem adaptation is in place, the token price may remain weak and range-bound under the influence of macroeconomic conditions and overall market sentiment. Historical data shows that price effects of public-chain infrastructure upgrades often release gradually over several months to a year after the upgrade is completed, rather than being concentrated at the exact moment the upgrade finishes.

Conclusion

The full activation of TON mainnet’s Sub-Second upgrade marks a key leap in its underlying technical architecture—from “high-throughput capability” to “real-time interaction experience.” Compressing finality time from about 10 seconds to about 1 second is not only an optimization of performance parameters, but also a substantive response to the question of whether a public chain can carry high-frequency real applications.

However, the gap between technical capability and user experience needs systematic ecosystem adaptation to be bridged. The rollout speed of Streaming API v2, developers’ responsiveness, and further prosperity of the Telegram mini-app ecosystem will jointly determine how fully the value of this upgrade is released. At the same time, the market’s early digestion of positive news and short-term speculative pressure cause a temporary decoupling between the token price and technical progress—this is a common “expectation pricing” phenomenon in crypto asset markets, and should not be interpreted simply as a rejection of technical value.

Over the next 6 to 12 months, the key focus for the TON ecosystem will shift from “whether infrastructure has been built” to “whether real users are using it.” On-chain activity, stablecoin transfer scale, and retention rates of high-quality applications will be core indicators for assessing the effectiveness of this upgrade. Telegram’s 1 billion-user pool provides room for imagination, and sub-second experiences provide technical confidence; the combined chemical effect of the two is worth ongoing tracking.
