Summary

Casper Network mainnet began on 31 March 2021 and is stewarded by the Casper Association, a Swiss non-profit. Since the Casper 2.0 upgrade on 6 May 2025 it runs Zug consensus, which replaced Highway. In each round a leader proposes a block, validators sign echo messages, and the round is committed when validators holding more than two-thirds of the era's validator weight vote yes; the block and its ancestors are then final, they are executed, and validators publish finality signatures over the result. Up to 100 validators, the top bidders in a stake auction, validate each era of about two hours, weighted by their own plus delegated CSPR. Slashing is disabled: a validator caught equivocating is skipped as leader, risks eviction and loss of rewards, and cannot take part in later eras. The Casper Association's public node reported protocol version 2.2.2 on 2026-09-29. 234517181921

Design

System
Layer 1 blockchainIndependent proof-of-stake chain with its own validator set; it does not settle to another chain. Its node software, WebAssembly execution engine, global state and staking auction are Casper's own. The name Casper Network is used by the Casper Association, and CSPR is the native token.

Who makes blocks
The node picks each round's leader pseudo-randomly in proportion to validator weight, and skips validators excluded for equivocating. Seats come from the auction system contract: at each era's switch block, bids plus delegations are ranked and the top 100 validate in the era after next. The current mainnet chainspec sets a 500 CSPR minimum bid, a 500 CSPR minimum delegation and up to 1,200 delegators per validator; validators set their own delegation rate.
Fork choice
No open weight-based chain selection. A proposal may build on a parent from an earlier round only when every round in between has been made skippable by a quorum of no votes, so two conflicting blocks cannot both be finalized while faulty weight stays at or below one-third. The docs say that if more than one-third of validators double-signed after finality, nodes could disagree and the network would shut down and need a manual restart.

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
Security Contested
Gives up
Open validator membership and liveness under heavy faults. Only the top 100 bidders validate in any era, and blocks stop when faulty or offline validators hold more than one-third of weight; the docs say a finality fault would need a manual restart. Blocks are at least 8 seconds apart on mainnet.Casper's own overview says the network solves the scalability trilemma and is optimized for security, decentralization and high throughput at once; reading that as all three corners is contested. With slashing disabled, misbehaving stake is not destroyed, which weakens the stake-at-risk side of the security argument. Validator count and stake concentration were not measured in this review.
Full node at home
Demanding 2141517Casper's docs recommend 4 CPU cores, 32 GB of RAM and an SSD of 500 GB for a node that keeps recent data (they add that current use is well below that, so operators can start smaller and grow) or 2 TB for an archive node, on Ubuntu or Debian, and a CPU with AVX2 and SHA extensions (AMD Zen or Intel Ice Lake or newer) for the official binaries. New nodes normally fast-sync from an operator-supplied trusted block hash and download only recent global state. Validating needs a winning auction bid for one of 100 seats.
Throughput claims
  • Theoretical peak 172023Theoretical peak; not comparable across chains or with observed load.Per-block caps, not a rate: 325 native transfers, 325 staking transactions, 1 install, and 1, 2 or 40 Wasm transactions by size lane; blocks at least 8 seconds apart.Casper publishes no transactions-per-second figure; these are configuration limits read by this review, not a measured rate. Blocks can take longer than the minimum block time, and each block is also bounded by its gas limit, byte size and approval count. Limits change with each upgrade's chainspec: the 2.1.1 release notes say block capacity was halved when block time was halved. No observed transaction rate or block interval 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 Casper Network: 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 swapsUnknownNo hash-time-locked or other trust-minimized swap mechanism was documented for Casper. A transaction has one initiating account whose own weighted keys authorize it, and WebAssembly contracts could host swap logic, but these are building blocks and no mainnet swap service was reviewed. 911
Authenticated data publicationUnknownNot assessed. Contract-level messages, added in Casper 2.0, store only a checksum of each message in global state, while the payload goes out once on nodes' event streams and is not kept by the protocol, so readers cannot count on retrieving the data later. ProofLayer, which the Casper Association presents as anchoring proofs to Casper, was not shown working on mainnet in the reviewed page. 121340
Light clientsBuilt into the protocolLimited scopeProtocol, limited: validators sign finality signatures over each executed block, block headers commit to the global state root, and state queries return Merkle proofs, so a client holding a trusted block hash and the era's validator weights can check blocks and state values without executing history. Fast sync starts from an operator-supplied trusted hash, and the chainspec requires strict finality signatures on blocks since 1.5.0. Limited: no maintained light client was reviewed, and a verifier must start from a trusted block hash and track validator changes era by era. 310121517
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 system on Casper was found in the reviewed documentation; absence was not verified.
Programmable spendingNative (protocol or core-team software) Earlier definitionAccounts carry weighted associated keys with separate thresholds for sending transactions and for key management, and WebAssembly session code and stored contracts, which can be upgraded, set the conditions for moving the purses they control. 91116
Protocol-verified messagingStructured assessment pendingNot yet assessed for any chain.
Reversible transfers or recoveryUnknownNo protocol feature for a sender to reclaim or cancel a payment was found. Casper's docs present weighted associated keys as account security and recovery: keys with enough weight for key management can remove a lost key and add a new one. That is key management by keys that already hold authority, a plain threshold, which this row does not count as a recovery path. The same page warns that recovery is impossible once too few keys remain for key management, because Casper does not support what it calls inactive recovery. 9
RollupsUnknownNo rollup anchored to Casper mainnet was found in the reviewed documentation; absence was not verified.
Shielded transfersStructured assessment pendingNot yet assessed for any chain.
Signed partial offersUnknownNot found. CEP-3009, used by the csprUSD stablecoin, lets a token holder sign a one-time transfer authorization that a facilitator submits; that authorizes a single payment, not one side of a trade that settles both legs together. 30
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.

Ecosystem & custody

Ecosystem products for Casper Network
Product typeStatusNotes and sources
Automated market makersThinCSPR.tradeThe Casper Association describes CSPR.trade as a Casper-native exchange built by Odra and MAKE on the Uniswap V2 automated market maker model and audited by Halborn; it opened on testnet at the end of 2025, and the Association reported it launched by February 2026. DeFiLlama's protocol list includes no Casper protocols, so liquidity and volume were not verified. 262739 As of Sep 29, 2026.
Issuer-native stablecoinsUnknowncsprUSD (Sarson Funds)Neither Circle's USDC list nor Tether's supported-protocol list includes Casper. csprUSD, a dollar stablecoin from Sarson Funds first launched in 2024, is being upgraded as the ecosystem's standard dollar token according to a July 2026 Association post; its mainnet contract, supply and reserve reporting were not verified. 303132 As of Sep 29, 2026.
Algorithmic stablecoinsUnknownNo algorithmic stablecoin on Casper was found; absence was not verified. As of Sep 29, 2026.
BridgesUnknownAstralBeam (MAKE Group; public testnet)AstralBeam, a bridge from MAKE Group between Casper and Ethereum, Base, Polygon and Robinhood Chain, was on public testnet at review, with mainnet planned for October 2026 per its own site. No other live bridge or wrapped CSPR on another chain was verified. Risk: AstralBeam locks tokens on the source chain and mints tokens on Casper once at least three of five relayers attest, so users would trust that relayer threshold and the bridge contracts, not Casper's validators. A wrapped asset is only as sound as the bridge that minted it. 2829 As of Sep 29, 2026.
Block explorersThinCSPR.live (MAKE)Casper's documentation names CSPR.live, which it calls one of the most popular Casper explorers, and names no other; the Association credits MAKE with its releases and its 2025 redesign. No second mainnet explorer was verified, and others were not reviewed. Listing is not a quality or completeness check, and explorer data is provider-indexed. 2526 As of Sep 29, 2026.
Hardware walletsEstablished in the ecosystemLedgerSee custody rows: Ledger lists Casper in its own wallet app with a Casper device app and routes staking through CSPR.live; Trezor states that it does not support Casper Network. 333738 As of Sep 29, 2026.

Hardware-wallet custody for Casper Network
Device makerStatusWhat users can and cannot do
LedgerNative supportSame as native: UnknownCan: Add a Casper account in Ledger Wallet (Ledger Live 2.73.1 or later) with the Casper device app and send or receive CSPR, per Casper's guide and Ledger's Casper page
Can: Delegate CSPR while signing on the device by connecting it to CSPR.live, per Ledger's staking page
Cannot: Stake from inside Ledger Wallet, as far as Ledger's own staking page shows: it sends users to CSPR.live to delegateLower confidence: Ledger Wallet's current code keeps Casper behind a feature switch that is off by default in code, and the remote switch setting was not read. The readable Ledger statements are its Casper coin page (modified 2024-01-10), which says CSPR can be sent and received in Ledger Live, and its staking page (modified 2026-06-24), which tells users to install the Casper device app from Ledger Wallet. Ledger's published currency list includes Casper with CSPR at nine decimals and a Casper device app. 3334353638 As of Sep 29, 2026.
TrezorNone foundSame as native: NoCannot: Manage CSPR in Trezor Suite; Trezor's Casper Network page says Trezor does not currently support Casper NetworkWhether any third-party Casper wallet signs with a Trezor device was not checked. 37 As of Sep 29, 2026.
