Summary

Telos is a delegated proof-of-stake chain. TLOS holders vote for block producers, and the 21 in the active schedule take turns: each gets a six-second round in which it produces up to 12 blocks, a target of one block every half second. Since the switch to Savanna consensus on 27 July 2026, each active producer also runs a finalizer that votes on valid blocks with a separate BLS key. Votes are aggregated into quorum certificates; with 21 equally weighted finalizers the Telos system contract sets the threshold at 15, and a certified chain moves the last irreversible block forward. Telos's node guides target TelosZero Core, its 2026 continuation of Antelope Spring; producers reported several software versions. Telos EVM is a smart contract on the same ledger, so EVM transactions are ordered and finalized by the same producers and finalizers. 24589192126

Design

System
Layer 1 blockchainIndependent delegated proof-of-stake chain, running since December 2018, with its own elected block producers; it does not settle to another chain. Its native layer, which Telos calls Telos Zero, was launched from the Antelope (EOSIO) codebase and now runs TelosZero Core, the Telos-maintained node software. Telos EVM runs on Telos as one smart contract (eosio.evm) on that same ledger, so it is part of this chain, not a separate layer.

Who makes blocks
Producers are chosen by continuous TLOS approval voting, weighted inversely so that voting for only one or two producers carries less weight. The top 21 form the active schedule; standby producers are rotated in periodically at half pay. The validator dashboard's data read on 2026-09-29 listed 38 registered producers, 21 active and 17 standby, all 21 active ones with an active finalizer key, which a producer needs before it can join the schedule. Producer pay is new TLOS issuance under a formula tied to an on-chain price oracle.
Fork choice
No open weight-based chain selection. The producer schedule fixes who may publish in each slot, and finality comes from finalizer quorum certificates: 15 of 21 equal weights must support a block, and nodes do not reorganise past the last irreversible block. Each finalizer keeps a local voting history so its key cannot vote for a conflicting branch after a restart. The Telos docs do not describe how nodes choose among uncertified competing branches. Before Savanna the last irreversible block trailed the head by about 330 blocks; Telos reported 2 after the switch.

Qualifications

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
Gives up
Open block production and open participation in finality. Only the 21 producers elected into the active schedule publish blocks and cast finality votes. With equal finalizer weights, any 7 of them withholding votes can stop blocks from becoming final, and 15 acting together can finalize. No stake slashing for producers or finalizers was found in the reviewed sources; the documented controls are voting, governance-set producer standards and schedule changes.Security is not listed as an emphasis because irreversibility rests on 15 of 21 elected finalizers behaving honestly, with no stake slashing found in the reviewed sources; readers who count fast committee finality as a security property may disagree. Telos presents half-second blocks, a fixed EVM gas price, first-in-first-out ordering and on-chain governance as its design aims. Its largest throughput figures come from a test network with raised block limits, and ordering without front-running is a rule producers are expected to follow, not something the protocol proves.
Full node at home
Demanding 56727Telos's guide sizes a read-only API node's chain-state memory at 32 GiB as a starting point for a host with 64 GB of RAM. A Telos EVM node adds telos-reth and a consensus client on top of the native node and needs at least 8 cores, 32 GB of RAM and a 1 TB NVMe drive, with 64 GB and 2 TB recommended. New nodes normally load a snapshot from a trusted provider rather than replaying history. For block producers Telos recommends 64 GB of ECC RAM, at least 8 dedicated cores, enterprise NVMe storage and at least two independent relay paths. Disk space for a native full node is not stated.
Throughput claims
  • Lab benchmark: 15,200 tx/s 22Controlled benchmark; not observed network behavior.Best one-second window (two consecutive blocks) in test runs reported by Telos in January 2024 on a Telos stage network (benchnet)Telos says standard validator hardware and several validator nodes were used; WASM overclocking was enabled on all nodes, a setting Telos says is discouraged on validators.Measured for simple EVM token transfers fired by six load generators at three API nodes on a test network, not observed on mainnet. The benchnet raised the block limits to 9,048,576 bytes of NET and 500,000 microseconds of CPU per block; mainnet uses 1,048,576 and 200,000. The test predates TelosZero Core, the Savanna finality switch and the telos-reth EVM stack, so current behaviour may differ. Co-verification was by a university student blockchain group working with the Telos core team, not an independent audit.
  • Lab benchmark: 1,826 tx/s 22Controlled benchmark; not observed network behavior.Same January 2024 benchnet test seriesMeasured for EVM swap transactions against a reference automated market maker on the same test network with raised block limits; the report names the pair both as TLOS and wrapped TLOS and as TLOS and a test token. Not an observed mainnet rate; mainnet block limits are lower than the benchnet's. The test predates TelosZero Core, Savanna and the telos-reth EVM stack.
  • Theoretical peak: 10,000 tx/s 19Theoretical peak; not comparable across chains or with observed load.Stated on a Telos EVM architecture page without a method, window or hardware description, so it is treated as a design claim. Telos's introduction page repeats a figure above 15,200 in an image description, which traces to the benchnet test. No observed mainnet rate was measured in this review.
Headline figures are not comparable across chains. A theoretical peak is never a like-for-like number.

Capabilities

Capabilities of Telos: 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 swapsBuilt into the protocolLimited scopeLimited to exchanges on Telos itself. A Telos transaction can carry actions authorized by several accounts, each signing with its own permission, and the actions all succeed or the whole transaction fails with state restored, so two parties can exchange TLOS and tokens in one transaction without an intermediary. No hash-locked or time-locked swap with other networks was reviewed. 1213
Authenticated data publicationUnknownNot yet assessed under this row's current definition. Contracts can keep data in on-chain tables paid for with RAM, but no documented flow was reviewed in which a publisher commits to data that readers retrieve and check against a commitment the chain records.
Light clientsUnknownNot yet assessed under the current definitions. Savanna finality produces quorum certificates with aggregated BLS signatures, and State History nodes can stream finality data, but no Telos light client or documented proof-based verification path was found; new nodes start from a trusted snapshot. 26
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 channelsUnknownNo payment or state channel on Telos was found in the reviewed sources; absence was not verified.
Programmable spendingNative (protocol or core-team software) Earlier definitionTelos Zero runs WebAssembly smart contracts, and every account has named permissions whose authority tables combine weighted keys, other accounts and thresholds, and can be linked to specific contract actions. Telos EVM runs Solidity contracts inside the eosio.evm contract, with TLOS as gas at a fixed price. 39101112
Protocol-verified messagingStructured assessment pendingNot yet assessed for any chain.
Reversible transfers or recoveryUnknownRecovery rests on building blocks only: an owner permission can be satisfied by other keys or accounts with weights and a threshold, a multisig threshold rather than a defined recovery path. Delayed sends are not offered: Savanna, active on mainnet since 27 July 2026, depends on the TelosZero Core features that disable deferred transactions, which turn the native action for cancelling a delayed transaction into a no-op and stop deferred transactions from executing. 12132021
RollupsUnknownNo rollup anchored to Telos was found, and absence was not exhaustively verified. The nearest features do not qualify: Telos EVM is a smart contract on the Telos ledger itself and posts no proofs or batches anywhere, and the Telos team's zkEVM test deployment of January 2025 settled to an Ethereum test network, not to Telos. 923
Shielded transfersStructured assessment pendingNot yet assessed for any chain.
Signed partial offersUnknownNot yet assessed under this row's current definition; no format in which a maker signs one side of a trade that any taker can later complete was found in the reviewed sources.
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.

Product typeStatusNotes and sources
Automated market makersThinUniswap v3 deployment on Telos EVM, Teloswap (swap.telos.net front end), Meridian SwapUniswap governance's official v3 deployments list names Telos (chain ID 40), recognized in February 2025 with GFX Labs as deployer, and in May 2026 Telos launched Teloswap as a front end for those contracts. DeFiLlama lists Uniswap V3, Meridian Swap, Telos Swap and several other exchanges on Telos, most with small listed liquidity and several marked as dead sites. Operators, audits and depth were not reviewed. 242831 As of Sep 29, 2026.
Issuer-native stablecoinsNone foundNeither Circle's USDC contract list nor Tether's supported-protocol list includes Telos. The USDC.e used by Telos Privacy on Telos EVM is a bridged token, not issuer-native. 142930 As of Sep 29, 2026.
Algorithmic stablecoinsUnknownNo algorithmic stablecoin with material use was verified. DeFiLlama lists Meridian Finance on Telos as a collateralized debt position protocol; its stablecoin design was not reviewed. 28 As of Sep 29, 2026.
BridgesFirst-partyTelos Bridge (LayerZero and Stargate)Telos documents its own bridge, built on LayerZero's V1 and V2 endpoints with the Omnichain Fungible Token standard, for moving assets between Telos EVM and networks including Ethereum, Base, BNB Smart Chain, Arbitrum, Avalanche and Polygon; TLOS itself is bridged out as such a token. Third-party routes such as RocketX are also listed. Moving TLOS between Telos Zero and Telos EVM happens inside the chain through the eosio.evm contract. Risk: Bridged transfers depend on LayerZero's message verification and on how the token contracts are configured, not on Telos consensus. A bridged token is only as sound as the bridge that minted it. 151732 As of Sep 29, 2026.
Block explorersFirst-partyTeloscan (Telos EVM), Telos Explorer (Telos Zero), EOS Authority (Telos view), BlocksscanTelos's docs describe Teloscan and the Telos Explorer as built by the Telos core developers; Teloscan's site now identifies itself as a Blockscout instance. EOS Authority and Ajor offer Telos Zero views, and Blocksscan did not respond on 2026-09-29. Explorer data is provider-indexed and listing is not a quality check. 1633 As of Sep 29, 2026.
Hardware walletsThinLedger (MetaMask with the Ethereum app; Anchor with the EOS app), Trezor (MetaMask or Rabby)See the custody rows: Ledger's own wallet code carries Telos EVM behind a switch that is off by default, and the documented working paths run through MetaMask or Anchor; Trezor Suite has no Telos network, so Trezor users sign through MetaMask or Rabby. 18343739 As of Sep 29, 2026.

Hardware-wallet custody

Hardware-wallet custody for Telos
Device makerStatusWhat users can and cannot do
LedgerPartialSame as native: UnknownCan: Sign Telos EVM transactions with a Ledger through MetaMask and Ledger's Ethereum app, as Telos's hardware-wallet guide describes
Can: Keep a native Telos Zero account key on a Ledger and sign through Anchor for desktop with the EOS device app, per Anchor's Telos page
Can: Add a Telos account in Ledger Wallet if Ledger's remote switch for Telos is on; Telos announced Ledger Live support for Telos EVM in 2023
Cannot: Rely on Telos appearing in Ledger Wallet: its code hides the Telos EVM network behind a feature switch that is off by default, and no readable Ledger page confirms it is on
Cannot: Manage native Telos Zero accounts in Ledger Wallet itself; Telos's 2023 announcement said native support was still being negotiatedCounted as limited support from the vendor itself under the shared custody rule. Ledger's published currency list (13.56.0) defines Telos with ticker TLOS and chain ID 40, signed with the Ethereum device app, but Ledger Wallet deactivates it unless its Telos feature switch is on, the switch is declared off by default, and the remote setting could not be read. Ledger's Telos coin page addresses returned 404. 18253435363738 As of Sep 29, 2026.
TrezorThrough an intermediaryMetaMask or Rabby (third-party wallet apps listed on Trezor's Telos page)Same as native: UnknownCan: Keep a Telos EVM address key on a Trezor Safe 3, Safe 5 or Safe 7 and sign through MetaMask or Rabby, which Trezor's Telos page lists
Can: Hold TLOS bridged to networks Trezor Suite supports, such as Ethereum or Base; those are bridged tokens on other chains, not the Telos network
Cannot: Manage Telos EVM accounts in Trezor Suite: Suite's current Ethereum network configuration has no Telos network (chain ID 40)
Cannot: Use native Telos Zero accounts: no Trezor path was documented by Trezor, Telos or Anchor in the reviewed pagesTrezor's Telos page is a template that says the Trezor Suite app works with Telos and lists Telos among TLOS networks next to networks that carry bridged TLOS. Under the custody rule the vendor's current wallet code decides, and it has no Telos network, so the documented path is a third-party wallet app. 17183940 As of Sep 29, 2026.
