The Open Network (TON)

The Open Network (TON) is a decentralized, originally developed by Telegram that supports scalable applications through a multi-chain architecture. It includes components like TON , DNS, Storage, Sites, and Proxy, and is designed for high throughput, cross-chain interoperability, and decentralized internet infrastructure. [1][2]

Overview

The Open Network (TON) is a decentralized originally developed by Telegram in 2018 and now maintained by the community. It uses a multi- architecture with a masterchain, multiple workchains, and sharding to support , , and related services such as TON DNS, TON Storage, TON Sites, and TON Proxy. Designed for scalability and high performance, TON has demonstrated the ability to process tens of thousands of transactions per second, with potential for much higher throughput. Its infrastructure emphasizes cross-chain interoperability and aims to provide the foundation for a decentralized internet ecosystem. [2]

History

Since 2017, the team at Telegram had been developing a new blockchain platform called the TON (Telegram Open Network) and a native called Gram. TON was a blockchain project created by brothers and to build a platform intended to disrupt the decentralized application space by leveraging Telegram’s wide user base. The platform aimed to offer speed and scalability, which were considered important for the mass adoption of . Through TON, Telegram users were expected to be able to buy, transfer, and store value in ID-verifiable wallets facilitated by the GRAM coin.

Telegram and its affiliates had not made any promises or commitments to develop applications or features for the TON or to otherwise contribute to the TON platform after its launch. Rather, the Telegram team hoped that the decentralized community of third-party developers would contribute to the TON ecosystem by developing applications and . In January 2018, the team released a and a detailed technical paper, which provided insight into the features and design of the project. TON was described as a platform for and services that could scale and support millions of transactions per second. [3] [4]

Gram

Gram was the native Telegram planned to launch to establish a platform for . To fund the development of Telegram and the TON project, Telegram attracted investments through a private Gram . A two-step legal scheme was employed: the Gram purchase agreement was structured as a future contract that allowed investors to receive tokens once TON launched. As futures were only sold to accredited investors, the was exempt from registration as securities under Regulation D of the Securities Act of 1933, on the basis that once TON was operational, the Grams would have utility and would not be considered securities. [27]

The ran in 2 rounds, each taking in $850 million. The first round offering was 2.25 billion tokens at $0.38 each, with a minimum purchase of $20 million, and the second offering was 640 million tokens at $1.33 each, with a minimum purchase of $1 million. As of April 2018, the firm had reported raising $1.7 billion through the ongoing . [29][28]

Development of TON

The development of TON took place in an isolated and opaque manner. The launch was initially scheduled for Q2 2018 with the launch in Q4, but the milestones were postponed several times. The was launched in January 2019 with a half-year deviation from the plan. [30]

In May 2019, the company released the lite version of the TON network client. In September 2019, the company released the complete source code for TON on GitHub, making it possible to launch a full and explore the . The launch of the TON main network was scheduled for October 31, 2019. [31][32]

Telegram vs SEC

The SEC (Securities and Exchange Commission) had concerns about Gram's private sale and contacted Telegram, but after months of communication, both sides could not agree. On October 11, 2019, a few weeks before the planned TON launch, the SEC obtained a temporary restriction order to prevent the distribution of Grams. SEC argued that the initial purchasers of Gram would be acting as underwriters, and the resale of Gram, once distributed, would be an unregistered distribution of securities. [5]

After a lengthy legal battle between Telegram and the SEC, Judge P. Kevin Castel of the U.S. District Court for the Southern District of New York agreed with SEC that the sale of Grams, the distribution to initial purchasers, and the highly likely future resale should be viewed as a single "scheme" to distribute Grams to the secondary market in an unregistered security offering. The "security" consisted of the whole set of contracts, expectations, and understandings around the sale and the distribution of tokens to the interested public, not only the Grams. In this case, the initial purchasers acted as underwriters that planned to resell tokens, not consume them. The restrictions on Gram distribution remained in force for purchasers based in and outside the U.S., as Telegram had no tools to prevent U.S. citizens from purchasing Grams on the secondary market. [5][33]

Following this development, the Telegram Open Network team announced that they could not launch the project by the expected 30 April 2020 deadline. [3]

On May 12, 2020, announced the end of Telegram's active participation with the TON blockchain. [6][8]

On June 11, 2020, Telegram settled with the SEC U.S. Securities & Exchange Commission and agreed to return $1.22 billion as "termination amounts" in Gram purchase agreements, and pay an $18.5 million penalty to the SEC. Telegram also agreed to notify the SEC of any plans to issue digital assets over the next three years. The judge approved the settlement on June 26, 2020:

"New and innovative businesses are welcome to participate in our capital markets, but they cannot do so in violation of the registration requirements of the federal securities laws," Kristina Littman, chief of the SEC Enforcement Division’s Cyber Unit, in a statement.

In 2020, Telegram repaid TON investors $770 million and converted $443 million into a one-year debt at 10% interest, raising its total liabilities to $625.7 million. On 10 March 2021, Telegram placed 5-year bonds worth $1 billion to cover the debts it returned by 30 April 2021. [10]

Post-SEC

Since TON (Telegram Open Network) was developed as an open-source software project and its code was publicly available on GitHub,  other projects started to develop the technology.

On May 7, 2020, the Free TON project was launched using the TON technology that had been developed. By January 2021, the community of the project reached 30,000 people. Free TON's token titled "TON Crystal" or just "TON" was distributed as a reward for contributions to the network. Of 5 billion tokens issued at the moment of launch, 85% were reserved for users, 5% for , and 10% for the developers (including 5% dedicated to TON Labs, the developer of TON OS middleware for TON blockchain, which is the essential part of Free TON). [5][34][35]

On June 29, 2021, the Telegram team said they would consider granting the use of the ton.org domain and GitHub repository to the TON Foundation, in response to an open letter. By August 4, 2021, the domain was transferred to the TON Foundation.

TON Foundation

After Telegram quit the project in May 2020, an open-source developer community led by Kirill Emelyanenko and Anatoliy Makosov initiated the NewTON open-source community to develop further and support TON on open-source principles. Developers who never worked for Telegram, members of the open developer community, , winners of public TON Blockchain Contests, and crypto enthusiasts from around the world joined them. [12] [23] [24]

Upon researching TON source code, architecture, and documentation, NewTON resumed developing in compliance with the original and ideas. [12]

In May 2021, the NewTON team was renamed as TON Foundation (The Open Network)— a not-for-profit community focused on the support and development of the network. [12]

Telegram CEO published a post on his official Telegram channel on December 23, 2021, backing the TON Foundation project. [25]

“When Telegram said goodbye to TON last year, I expressed the hope that future generations of developers would one day carry on with our vision of a mass-market blockchain platform, So I was inspired to see the champions of Telegram’s coding contests continue developing the open TON project, which they rebranded to Toncoin.” - he wrote.

TONCOIN

The Telegram native Gram, was rebranded into TON coin (The Open Network) after the TON Foundation took over the abandoned project in 2020. [36]

TON coin is the principal  of The Open Network (TON) , particularly its masterchain and basic workchain. It is used for , securing the through , deciding how the network develops, payments (i.e.,  message processing fees), and settling payments. [11][4]

Background

In November 2019, Telegram Open Network testnet2 launched, and 5 billion coins were minted, with a small fraction (1.45%) distributed to developers and testers. In May 2020, after the SEC prohibited Telegram from issuing Grams to investors, Telegram ceased its work on the TON ecosystem, and testnet2 tokens were placed into 20 Giver . Finally, in May 2021, by a majority vote of network participants, testnet2 was promoted to . Coins continued to be distributed by Giver contracts. [11]

Tokenomics

The total supply of TON coins was originally limited to 5 Gigatons (i.e., 5 billion TON coins). This supply will gradually increase, as rewards to for new masterchain and shardchain blocks accumulate. The expected inflation rate of 2% per year will double the total supply of TON coins (to 10 Gigatons) in 35 years. This inflation represents a payment made by all community members to the for keeping the system up and running. [4]

Utility

The TON coin can be used as a processing fee for transactions, cross-chain transaction fees, lending capital to to earn interest, and payment for -based domain names (DNS). It can also act as stakes required to maintain the , and payments services provided by apps built on the platform, and it is integral to TON's on-chain governance program. [11]

TON Blockchain

The TON Blockchain is the foundational infrastructure of The Open Network, structured to maximize scalability, flexibility, and speed. It operates using a and is organized into three hierarchical layers: masterchain, workchains, and shardchains.

At the top, the masterchain is the main that secures the network and contains metadata essential for coordinating the entire system, including information, protocol parameters, and references to all other chains. All transactions and state updates across the network are finalized on the masterchain.

The second layer consists of workchains, which are individual with potentially unique rules, such as different transaction formats, address types, virtual machines for , and even native tokens. Despite their differences, all workchains remain compatible with the masterchain, ensuring cross-chain communication and coherence across the system.

Each workchain is subdivided into shardchains—parallelized sub-chains that divide the workload across multiple . This bottom-up sharding design, known as the Infinite Sharding Paradigm, allows TON to generate new shards as needed, enabling elastic scalability. This architecture supports the network’s goal of processing millions of transactions per second without bottlenecks. [5]

TON Key Components

TON Payments

TON Payments is a platform for micropayments and a micropayment channel network. It can be used for instant off-chain value transfers between users, bots, and other services. Safeguards built into the system ensure these transfers are as secure as on-chain transactions. [12]

TON Proxy

This is a network proxy/anonymizer layer for TON . Similar to I2P, it allows the building of decentralized VPN services and -based alternatives to achieve anonymity and protect online privacy. Combined with the TON Network and TON DNS, TON Proxy gives decentralized apps immunity to censorship. [12]

TON Proxy Launch

The TON Proxy, compatible with HTTP Proxy, launched on September 30, 2022. A host of TON wallets said they would implement TON Proxy directly in their wallet applications and extensions, meaning that all TON wallet owners would access the TON network without downloading additional applications. [22]

TON DNS

TON DNS makes mainstream by assigning human-readable names to accounts, , services, and network . With TON DNS, browsing becomes similar to surfing the World Wide Web. [12]

TON DNS Launch

The TON Foundation, on June 30, 2022, announced the launch of TON DNS. Similar to other popular -related domain names like “.eth” or “.crypto,” the domain zone for TON DNS is “.ton,” and it enables users to access simply. With TON DNS, users can use simple and short domain names instead of typing in a long string of letters and numbers. A domain name will also be able to unlock a wallet address. [19]

TON Storage

TON Storage is a distributed file-storage technology accessible through the TON Network. This torrent-like technology relies on for availability and has strong potential concerning storing and exchanging large amounts of data. [12]

TON Storage Launch

The TON Storage was launched on January 5, 2023, taking on similar projects like and Storj. TON Storage works similarly to internet-based peer-to-peer file sharing that uses torrents. But instead, it relies on the TON network to transfer data files of any size, which are backed up and encrypted without needing centralized web servers. With the launch of TON Storage, TON-secured sites can be hosted on the network, a move that TON Foundation founding member Anatoliy Makosov said marks [12]

“the next step in realizing our vision of a decentralized, open internet.”

TON Services

TON Services provides a versatile platform for third-party services. It enables smartphone-like friendly interfaces for and , and a World Wide Web-like decentralized browsing experience. [12]

TON Wallets

TON Wallet is a wallet that provides fast, secure, -based payments without intermediaries. TON Wallets give users direct control without middlemen or bankers. [37][38]

TON's non-custodial wallets include: Tonkeeper, Tonhub, TON Wallet, and Coin98 wallet, while its custodial wallets include @wallet and @crypto bot. [38]

Telegram Wallet Bot

On April 26, 2022, TON announced on Twitter the development of payment options on Telegram using a Wallet Bot. [40]

"It’s a new way to send Toncoin without transaction fees to any Telegram user. With this service, you’ll no longer need to enter long wallet addresses and wait for confirmations"

Ton Nominator Pools

TON nominator pools are a mechanism that allows holders to lend their profits to nominators to earn profit. It also allows to be rewarded based on how much stake they hold. Nominator Pools are assets of a and nominators managed by a . guarantee the correct use of borrowed coins. [42]

Governance

By design, network modifications within TON are only possible if approved by the majority of  via the  consensus. Changing network software, configuration, or state is impossible by bypassing the vote. [12]

Telegram Marketplace

Telegram launched a -based marketplace called Fragment on October 26, 2022, enabling the auction of rare and short Telegram username handles using The Open Network (TON) . Initially focused on four

  • and five-character usernames, the platform set minimum bids—such as 10,000 Toncoin for four-letter handles—and allowed individual users to buy, sell, and transfer ownership of usernames across different marketplaces, with all ownership transparently recorded on-chain.

The idea for the marketplace emerged after successful TON DNS auctions earlier that year, and Telegram positioned the initiative as part of a broader integration strategy. Within its first month, sales on Fragment surpassed $50 million, with high-profile handles like @news fetching nearly $1.7 million. The platform marks a shift in digital identity control, offering verifiable ownership of social media identifiers and expanding the use case for in mainstream communication apps. [15] [16] [17]

TON x Donate

On December 23, 2021, TON announced a partnership with Donate, saying that users would soon be able to make donations and pay for their subscriptions in Toncoin. At the same time, channel administrators can collect their income in . [20] [21] [41]

Developments

Ton Foundation x Libre

In April 2025, The Open Network (TON) Foundation partnered with Libre, a decentralized infrastructure firm specializing in , to introduce a $500 million tokenized bond fund tied to Telegram.

In the statement, the Telegram Bond Fund (TBF) offers -based access to institutional-grade yield opportunities. The TBF signals TON’s official entry into the growing sector and aligns it with other prominent networks that support tokenization. [43]

The TBF brings a portion of Telegram’s $2.35 billion outstanding bonds onto the TON , allowing institutional and accredited investors to engage with traditional financial products through a decentralized format. The fund aims to support Telegram’s current and future bond offerings, offering compliant on-chain exposure through a trusted platform. Max Crown, CEO of TON Foundation, said: [43]

“Libre’s infrastructure bridges the gap between compliance and decentralization, unlocking powerful new opportunities for TON’s community to engage with RWAs in a secure and accessible way.”

TON x Ethena

On May 1st, 2025, at the event held in Dubai, TON and announced a partnership which will see the deployment of and (sUSDe) natively within the TON . [44]

The deployment involves two major integrations, including one in the custodial Wallet in Telegram and the second in the TON Space wallet, a self-custodial wallet integrated in the messenger.
