Summary

Proof-of-stake network with a masterchain that holds configuration and the validator set and records the latest block of every shard, plus workchains (the main one holds ordinary accounts) that split into shardchains by address prefix as load rises and merge as it falls. Since April 2026 mainnet runs Catchain 2.0, a leader-based Byzantine-fault-tolerant protocol described in TON's Simplex whitepaper: validators take turns proposing and a block is finalized on votes worth at least two-thirds of stake, assuming less than one-third of stake is faulty. Every account, including each wallet, is a smart contract, and contracts interact only through asynchronous messages. 2345671519

Design

System
Layer 1 blockchainOne permissionless layer-1 network made of a masterchain plus workchains that split into shardchains. Shards are part of the base protocol and are run by TON validators; they are not separate chains or rollups. The native coin was renamed from Toncoin (TON) to Gram (GRAM) on 2026-06-15; the network is still called TON.

Who makes blocks
Validators who lock Gram as stake (documented technical minimum 300,000 Gram, about 1,000,000 in practice). Each slot window has a leader chosen in rotation from the validator set. The August 2026 node release added collators, specialized nodes that can build blocks for validators; their use on mainnet was not verified.
Fork choice
No weight-based fork choice: a block is finalized once votes from at least two-thirds of stake are collected, so conflicting finalized blocks would need more than one-third of stake to misbehave. A shard block is final once a finalized masterchain block references it; statuses shown before that point can still be rolled back.

Tradeoffs

This view follows one way of thinking about design priorities, often called the blockchain trilemma. The design-priorities lesson sets out the counter-view. Read the design-priorities lesson.

Emphasizes
Scalability and Security Contested
Gives up
Operational decentralization: running a full node or liteserver needs data-center-grade hardware and bandwidth, validating needs hundreds of thousands of Gram in stake, the active validator set is a few hundred operators, and Telegram said in May 2026 that it was becoming the largest validator. Blocks also stop finalizing if more than one-third of stake is offline.Security here means Byzantine-fault-tolerant finality while less than one-third of stake is faulty; penalties beyond the fine for low block production were not verified. The project calls TON fast, secure and scalable and, in May 2026, one of the most decentralized networks with about 400 validators and Telegram's stake as a counterbalance. That claims all three goals, which this review treats as disputed: the stake minimum, data-center hardware and unmeasured stake concentration point the other way. The liveness point is inferred from the two-thirds rule.
Full node at home
Data-center class 1314TON's node guide lists 16 cores, 128 GB RAM, at least 1 TB NVMe, at least 1 Gbps and about 16 TB of traffic per month at peaks for a liteserver; validators need 16 dedicated cores, 128 GB RAM and about 64 TB per month; archive liteservers need 20 TB or more of storage. All need a static public IPv4 address. The guide offers no smaller home profile.
Throughput claims
  • Lab benchmark: 100,000 tx/s 114Controlled benchmark; not observed network behavior.ton.org states a verified '100K+' figure from a public test.Date, duration and network size of the test are not stated on the cited page.Not stated for the test. TON's own node guide lists 16 cores, 128 GB RAM and at least 1 Gbps for ordinary liteservers and validators.The cited page gives no date, validator count, transaction mix or independent observer for the test. A public test is not observed mainnet load; the figure says nothing about state growth or propagation to ordinary nodes at that rate. Which consensus version the test ran on is not stated; mainnet changed consensus in April 2026.
  • Theoretical peak 2Theoretical peak; not comparable across chains or with observed load.No number given: the 2021 whitepaper says the design could handle millions of transactions per second if necessary.A design aspiration based on splitting into many shards, not a measurement. Any aggregate rate across many shards would depend on many validator groups running data-center-grade nodes; no single ordinary node would process all of it.
Headline figures are not comparable across chains. A theoretical peak is never a like-for-like number.

Capabilities

Capabilities of TON: how each one is provided, or its research status
CapabilityHow it is providedNotes and sources
Account abstractionStructured assessment pendingNot yet assessed for any chain.
Atomic swapsUnknownNot yet assessed under the current definitions; no documented hash- and time-locked swap standard for TON was found in reviewed documentation. Because contracts interact through asynchronous messages, a swap spanning several contracts is not one all-or-nothing transaction unless contract logic makes it so. 8
Authenticated data publicationCore-team softwareLimited scopeTON Storage shares files as hash-identified bags that readers check chunk by chunk against a Merkle root, and storage-provider contracts keep that root on-chain and demand periodic storage proofs. Its official implementation, storage-daemon, ships in the TON software suite from the ton-blockchain maintainers, who publish the reference node. Limited: the root is on-chain only when a storage-provider contract is used, and no way to publish or discover updated data is documented. 12
Light clientsBuilt into the protocolLimited scopeConsensus produces what a light client checks: masterchain blocks signed by validators. Lite clients query liteservers and check Merkle proofs against a trusted masterchain block. Limited: lite clients depend on liteservers for data, and TON's docs note that trusting that starting block needs key-block syncing or validator-signature checks. Verification code exists in several libraries. 11
Native staking or delegationStructured assessment pendingNot yet assessed for any chain.
On-chain governanceStructured assessment pendingNot yet assessed for any chain.
Parallel executionStructured assessment pendingNot yet assessed for any chain.
Payment or state channelsPartial (layer not stated) Earlier definitionA payment-channel contract from the core organization and a community payment-network implementation exist; the reference repository is inactive since 2022 and mainnet usage was not verified. 2021
Programmable spendingNative (protocol or core-team software) Earlier definitionEvery account, including each wallet, is a smart contract run by the TON Virtual Machine; wallet contracts check an Ed25519 signature, a sequence number and an expiry time, and custom contracts can impose their own spending rules. This is built into the account model, not an add-on. 89
Protocol-verified messagingStructured assessment pendingNot yet assessed for any chain.
Reversible transfers or recoveryUnknownNot yet assessed under the current definitions; no way for a sender to cancel or reclaim a payment, and no recovery path, was found. A standard vesting contract releases coins on a cliff-and-period schedule and lets the recipient return locked coins to the original sender, but the sender cannot take them back on its own. 10
RollupsUnknownAbsence was not verified, so the rule that absence needs a source makes this unknown rather than not present. Earlier finding: no rollup settling to TON was found in reviewed sources; TAC is a separate chain linked by a sequencer network, and TON's shardchains are part of the base protocol. 622
Shielded transfersStructured assessment pendingNot yet assessed for any chain.
Signed partial offersUnknownNot yet assessed under this row's current definition.
Reading these values
How this feature is provided
Built into the protocol, core-team software or independent software says where a feature lives and who can change it. These are implementation layers, not quality: core-team software is not closer to the protocol than independent software.
Structured assessment pending
The shared review has not assessed this feature for any chain yet (Account abstraction, Native staking or delegation, On-chain governance, Parallel execution, Protocol-verified messaging and Shielded transfers). That does not mean it is absent, and a chain’s profile may already describe it.
Unknown
The review has not established this for this chain under the current definition; the note beside it says why. Unknown is not absent and not a low score. A feature reads “Not present” only when a source shows it is absent.
Earlier definition
Payment or state channels, Programmable spending and Rollups keep the earlier definition until the next fact-check. There, “Native” does not separate the protocol from core-team software, “Ecosystem software” does not say who publishes it, and “Partial” does not say which layer.
Reading across rows
The list of capabilities is incomplete. Do not read these rows as a chain leading or lagging overall.

Algorithmic stablecoinsUnknownAlgorithmic, synthetic or hybrid dollar tokens on TON were not reviewed. As of Sep 27, 2026.
BridgesEstablished in the ecosystemTAC TON Adapter, Legacy TON bridges to Ethereum, BNB Chain and PolygonTON's documentation marks its original bridges as legacy and not recommended and points to third-party bridge providers without naming them; TAC links TON to its EVM chain through a sequencer network. Risk: Every route relies on parties outside TON consensus: the legacy bridges' operators (whose trust model current docs do not describe, and which the docs warn can be deprecated at any moment), TAC's sequencer groups and validators (TAC says its sequencer network is distributed but not yet decentralized), or third-party bridge operators. A bridged token is only as sound as those parties and their contracts. 1723 As of Sep 27, 2026.
Block explorersEstablished in the ecosystemTON explorer (explorer.toncoin.org), Tonviewer, TonscanTON's docs link the low-level TON explorer; Tonviewer is operated by Keeper per its footer, and ton.org links Tonscan. Explorer data is provider-indexed; listing is not a quality check. 1183031 As of Sep 27, 2026.

Device makerStatusWhat users can and cannot do
LedgerNative supportSame as native: UnknownCan: Hold, send and receive the coin, still listed by Ledger as Toncoin (TON), in Ledger Wallet with keys on a Ledger device
Can: Buy or swap the coin inside Ledger Wallet through the providers Ledger integratesLower confidence: Ledger Wallet's code has a TON feature switch that is off by default, and the only readable sign that it is on for users is Ledger's templated coin page. That page does not say whether jettons such as USDT on TON, NFTs or staking are supported. The TON device app's README mentions only the version 4 wallet contract and says the app must be sideloaded, so it looks out of date. 323338 As of Sep 27, 2026.
