Overview and Development History of the TON Network
The Open Network (TON) is a decentralized blockchain project, with Toncoin as its native cryptocurrency. TON was initially developed by the instant messaging application Telegram team. However, due to regulatory pressure from the U.S. Securities and Exchange Commission (SEC), Telegram withdrew in 2020, and the project was taken over and continued by the community. In 2023, Telegram re-announced its support and deep integration with the TON ecosystem, bringing new development opportunities. Nevertheless, as its ecosystem expands and user attention grows, the TON network also faces a series of cybersecurity challenges.
Major Security Challenges Faced by the TON Network
- Network Outage Incident: On August 27, 2024, the TON network experienced a significant outage, resulting in over four hours without new block production. During this period, major cryptocurrency exchanges suspended TON network deposit and withdrawal services, highlighting potential risks to network stability.
- Smart Contract Vulnerabilities: In the "Toncoin Smart Contract Security Best Practices" released in September 2024, the SlowMist security team pointed out that TON smart contracts may have various common vulnerabilities, such as missing 'impure' modifiers, improper use of mutable/immutable methods, and insecure randomness, all of which could be maliciously exploited.
- Scams and Illicit Activities: Since November 2023, cybersecurity firm Kaspersky has reported that scammers have begun using fake Telegram bots and phishing attacks to steal Toncoin through sophisticated referral schemes. Additionally, Analyst1's research in September 2023 indicated that Toncoin has been used in cybercriminal activities, for example, the pro-Russian hacker group KillNet used Toncoin, suggesting that its deep integration with Telegram may increase its popularity in cybercrime.
- Centralization Concerns: In May 2026, Telegram founder Pavel Durov confirmed that Telegram would replace the TON Foundation as the primary operator of the TON blockchain and plans to become the largest validator, holding a staked share of approximately 2.2 million TON coins. While this move aims to strengthen network security and technological advantages, it has also sparked community discussions about potential centralization risks and regulatory scrutiny.
TON Network Security Solutions and Development
To address the aforementioned challenges, the TON ecosystem has adopted various measures to enhance its network security and stability:
- Security Collaboration and Audits: The TON Foundation actively collaborates with several leading blockchain security companies. In October 2023, it partnered with Elliptic to provide data intelligence and ecosystem security, screening TON wallet addresses and flagging bad actors. In March 2024, it collaborated with Fireblocks and DWF Labs to enhance the accessibility and security of the TON ecosystem, with Fireblocks' integration particularly improving enterprise-grade security infrastructure. Furthermore, companies like SmartState and Trail of Bits also provide security audit services for TON protocols and smart contracts and establish security standards for DeFi protocols.
- Technical Upgrades and Performance Optimization: The TON network continuously undergoes technical iterations to improve its robustness. On April 9, 2026, Catchain 2.0 was activated, significantly reducing block production time from approximately 2.5 seconds to 400 milliseconds, transaction finality from about 10 seconds to approximately 1 second, and throughput is estimated to increase by about 10 times. These upgrades not only enhance user experience but also strengthen the network's resistance to attacks. The security and robustness of TON's core node components are also continuously improving.
- Smart Contract Security Best Practices: The "Toncoin Smart Contract Security Best Practices" released by the SlowMist security team provides important guidance for developers, helping them understand and mitigate potential threats, thereby improving the overall security of smart contracts within the TON ecosystem.
- Telegram's Deep Involvement: Pavel Durov announced in May 2026 that Telegram would increase its control over TON and become the largest validator. This aims to further strengthen the TON network's security and technological leadership through Telegram's technology and user base, and to widely promote Web3 applications. Although it has sparked centralization discussions, the resources and technical support it brings are expected to aid TON's secure development.
TON Coin Trading and Market
Toncoin, as the core of the TON ecosystem, saw its transaction fees reduced to approximately 0.00039 TON in May 2026, which is about one-tenth of a cent, and fees are fixed, not fluctuating with network congestion. Validators receive approximately 0.6% of the total supply annually as rewards, incentivizing network participants to maintain its security. Currently, Toncoin can be traded on exchanges that support the token. According to the latest market data, users can find Toncoin trading pairs on platforms such as Upbit, Bithumb, WEEX, DigiFinex, and XT.COM.
