What is Internet Computer
The Internet Computer (ICP) is a network of independent blockchains called subnets that host smart contracts, called canisters, able to serve full web applications. ICP is its native token: it is converted into cycles to pay for computation and storage, and staked in the Network Nervous System to govern the network.
Network and consensus
| Parameter | Details |
|---|---|
| Type | Network of independent subnet blockchains, usually 13 to 40 nodes each, that run in parallel |
| Consensus | ICP consensus with cryptographic (not probabilistic) finality; safe while fewer than one third of a subnet's nodes are faulty |
| Block time | Finality in 1 to 2 seconds |
| Smart contracts | Yes; canisters are WebAssembly programs (for example Motoko or Rust) with their own persistent memory |
| Runs on | Nodes owned by independent node providers, admitted by governance vote |
Supply and issuance
| Parameter | Details |
|---|---|
| Issuance | New ICP is minted for governance voting rewards and node provider rewards |
| Fee burn | ICP converted into cycles is burned; cycles can never be turned back into ICP |
| Inflation | ICP minting was 9.72% in January 2026; the DFINITY Foundation's Mission 70 aims to cut inflation by at least 70% by end-2026 |
| Maximum supply | No fixed cap; supply depends on the balance between minting and burning |
On 31 October 2026: 558,194,257 ICP in circulation, 558,194,257 ICP in total (source: ICP ledger API (internetcomputer.org dashboard backend); values are in e8s (1 ICP = 100,000,000 e8s); timestamp 1793466000 = 31 October 2026 17:00 UTC).
What ICP is used for
- Converted into cycles, which pay for canister computation, storage and bandwidth
- Locked in neurons to vote on Network Nervous System proposals and earn voting rewards
- Paid out as rewards to node providers
Who develops and governs Internet Computer
- Governance
- The Network Nervous System (NNS), an on-chain DAO, controls the protocol; adopted proposals can upgrade node software without hard forks
- Voting
- Neurons need at least 1 ICP and 2 weeks of dissolve delay to vote; voting power grows with stake, lock-up and age
- Foundation
- The DFINITY Foundation, a not-for-profit, leads research and development
- Developer
- The DFINITY Team publishes the technical whitepaper; code is in the dfinity GitHub organisation
History
| Date | Event |
|---|---|
| May 2021 | Network genesis: the Internet Computer mainnet launches. |
| 18 December 2023 | The DFINITY Team publishes version 1.4 of the technical whitepaper, The Internet Computer for Geeks. |
| 6 February 2026 | The DFINITY Foundation publishes the Mission 70 paper proposing lower voting and node rewards to reduce ICP inflation. |
Security and audits
- Each canister is replicated on every node of its subnet, so a single node cannot change its state.
- The protocol does not protect against bugs in application code; developers are responsible for their canisters.
Risks and caveats
- ICP has no supply cap and has been inflationary; minting was 9.72% a year in January 2026.
- Most application canisters run on 13-node subnets; fewer nodes give weaker guarantees than larger subnets.
- Locked ICP in neurons can take up to two years to dissolve before it can be withdrawn.

Questions and answers
What is the Internet Computer?
It is a network of subnet blockchains that host canister smart contracts able to serve full web apps. ICP is its native token.
Who created the Internet Computer?
It is developed by the DFINITY Foundation, a not-for-profit; mainnet genesis was in May 2021.
What is the supply of ICP?
There is no fixed cap. The ICP ledger reported 558,194,256.7 ICP on 31 October 2026; minting and cycle burns change it.
How does ICP pay for computation?
ICP is converted into cycles, pegged so that 1 trillion cycles equal 1 XDR; cycles are burned as canisters run.
How is the Internet Computer governed?
By the Network Nervous System, an on-chain DAO where ICP holders lock tokens in neurons and vote on proposals.

How voting works
Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
