What is Casper Network?
Casper Network is a public proof-of-stake blockchain that launched in 2021 and now pitches itself as infrastructure for tokenized real-world assets, institutional workflows and AI agents. CSPR is its native token: it pays transaction fees, which have been burned since late 2025, and is staked to choose and reward the validators that run the network.
Utility Lens
What Casper Network actually does
Runs smart contracts and records ownership of tokenized assets on a public chain with fast, final settlement and built-in permission controls.
- Real-world usage
- earlyThe network, DEX and staking are live, but Casper publishes few verifiable figures on real-world asset or enterprise use.
- Token necessity
- integralCSPR pays every transaction fee and is staked to select and reward validators, though apps can be built on other chains.
- Decentralization
- moderateValidators and delegators stake CSPR and vote on upgrades, but the Swiss nonprofit Casper Association drives development and now receives a share of new issuance.
- Track record
- provenMainnet launched in 2021; in July 2024 a security breach affecting a limited number of accounts led validators to halt the chain for several days.
What it’s used for
Developers build apps and token projects on Casper, and holders stake or delegate CSPR to validators to earn rewards. The ecosystem includes a decentralized exchange (CSPR.trade) and liquid staking, and the Casper Association is now promoting tools for AI agents. Casper's own pages focus on features and partnerships rather than detailed usage data, so the scale of real-world asset activity on the chain is hard to measure.
Role of the CSPR token:
Evidence of real use
- Casper 2.0 went live on mainnet on May 6, 2025, adding Zug consensus with instant finality, upgradable contracts and native access controls, after a Halborn security audit. Source (opens in a new tab)
- Casper 2.1, activated in December 2025, cut the maximum block time from 16 to 8 seconds and began burning all transaction fees. Source (opens in a new tab)
- Validators approved Governance Vote #008, which added a one-time 33% issuance and split the 8% annual emissions into 6% for validator rewards and 2% for ecosystem development. Source (opens in a new tab)
- Kraken opened CSPR trading on July 21, 2026, and the Casper Association says eligible US users can now trade CSPR there. Source (opens in a new tab)
ISO 20022: claim vs. reality
- What’s documented
- No documented ISO 20022 product. In December 2025 Casper's official X account posted that CSPR is “among ISO 20022–aligned digital assets”, linking to CoinMarketCap's ISO 20022 category, which lists CSPR. We found no ISO 20022 message tooling, bank pilot or standards-body membership in Casper's own materials.
- What you’ll hear online
- CSPR is an approved ISO 20022-compliant blockchain chosen for the new global banking system.
- Reality check
- ISO 20022 is a bank messaging standard; it does not certify or endorse any cryptocurrency, and the official ISO 20022 site says cryptocurrencies are not inherently compliant with it. A data site placing CSPR in a category is not approval by any standards body, and Casper's documented features have nothing to do with ISO 20022 messages.
How Casper Network works
Casper is a layer-1 proof-of-stake network. Validators lock up CSPR, both their own and tokens delegated by other holders, and earn rewards from new issuance for producing blocks. Since the Casper 2.0 upgrade in May 2025, they reach agreement with a protocol called Zug, which gives deterministic finality: once a block is final it cannot be reversed. The Casper 2.1 upgrade in December 2025 cut the maximum block time to 8 seconds.
The network's pitch to institutions rests on a few features. Smart contracts can be upgraded in place, accounts can require several signatures, and fine-grained permissions let each party to an asset deal, such as a broker or auditor, use only the functions it is allowed to. Casper 2.0 also added liquid staking and support for more than one virtual machine. More recently the Casper Association has promoted an AI toolkit with x402 payment support for software agents.
CSPR has three jobs. It pays transaction fees, and since Casper 2.1 those fees are burned rather than handed to validators. It is staked or delegated to secure the network and earn rewards from new issuance. And validators use their stake to vote on protocol changes, as they did in February 2026 when Governance Vote #008 approved a one-time issuance to fund exchange listings, bridges and liquidity.
Key moments
- 2021Casper mainnet goes live.
- 2024In July a security breach affecting a limited number of accounts leads validators to halt the network until a fix is deployed.
- 2025Casper 2.0 goes live in May with Zug consensus and native access controls, and Casper 2.1 adds fee burning and faster blocks in December.
- 2026Validators approve Governance Vote #008 in February, Casper 2.2.0 puts it into effect in March, and Kraken lists CSPR in July.
Supply
CSPR has no fixed cap. Base inflation is 8% a year, and since Vote #008 6 percentage points go to validator and delegator rewards and 2 points to the Casper Association for ecosystem work. The same vote approved a one-off issuance equal to 33% of CSPR supply, about 4.76 billion new CSPR, most of it locked and staked on a two-year unlock schedule. Since Casper 2.1, all transaction fees are burned, which offsets some issuance.
Risks to understand
- Dilution: 8% yearly inflation plus the 2026 one-time 33% issuance add a lot of new CSPR, and fee burning only offsets part of that if usage stays low.
- Unproven demand: Casper's real-world asset and AI-agent plans face strong competition, and usage figures are hard to verify.
- Past security incident: a July 2024 breach led validators to halt the chain for several days.
- Association influence: the Casper Association drives development and now receives a share of new issuance to fund its work.
- ISO 20022 hype: Casper's ISO 20022 link rests on a CoinMarketCap category, not on a documented ISO 20022 product.
Casper Network FAQ
What is CSPR used for?
CSPR pays transaction fees, which are burned, and is staked or delegated to validators to secure the network and earn rewards.
What changed with Casper 2.0 and 2.1?
Casper 2.0 in May 2025 brought Zug consensus with instant finality, upgradable contracts and permission controls. Casper 2.1 in December 2025 halved the maximum block time and started burning all fees.
Is Casper an ISO 20022 coin?
Casper's X account has called CSPR 'ISO 20022-aligned' because CoinMarketCap lists it in that category, but we found no ISO 20022 product, and the standard does not certify cryptocurrencies.
Can I buy CSPR in the US?
As of October 2026 Kraken lists CSPR for eligible US customers, while Coinbase does not offer it.
