Decentralized computing runs programs on a network of independent machines instead of servers controlled by one company. Blockchains are a widely known form: many nodes execute or verify the same programs, called smart contracts, so the result does not depend on trusting a single operator. Decentralized cloud networks are a related form, where independent providers offer processing power and a protocol coordinates jobs and payment.

How do decentralized computing networks work?
There are two broad models.
In replicated execution, many nodes run the same computation and agree on the result through consensus. This is how blockchains work. It is highly resilient and verifiable, but every node repeats the work, so each computation is expensive.
In marketplace compute, a job runs on one provider or a small group. The network keeps providers honest with staking, reputation, running the same job on several providers, or cryptographic proofs. This suits heavy workloads that would be impractical to replicate on every node.
Proofs connect the two models. A validity proof, often built with zero-knowledge techniques, lets one machine show that a computation was done correctly, and others can check the proof without running the computation again.
How does blockchain enable decentralized computing?
A blockchain gives a decentralized network the pieces a single company would otherwise provide: a shared state everyone agrees on, rules for executing programs the same way on every node, a native way to pay for computation, and a public record of what ran. Ethereum describes itself as a blockchain with a computer embedded in it, whose state every node agrees on. Anyone can deploy a program to it, and anyone can call that program.
How does decentralized cloud compare to traditional cloud?
| Model | Who runs the machines | How you pay | Why you trust the result |
|---|---|---|---|
| Traditional cloud | One provider | An account with the provider | The provider's reputation and contract |
| Blockchain execution | Many independent validators | Transaction fees | Consensus across nodes |
| Decentralized compute network | Independent providers | Payment through the protocol | Staking, redundancy, or proofs |
The benefits of decentralized infrastructure are open access, no single operator who can stop the onchain logic, and results that others can verify. The trade-offs are higher cost for replicated work, more variable performance, and less mature tooling than established cloud platforms.
Can I run applications on decentralized cloud networks?
Yes, and many decentralized applications mix several layers. Logic that needs shared trust, such as balances and settlement, runs in smart contracts. Heavy computation can run on compute networks or offchain with a proof. Large files are often kept offchain, for example in decentralized storage. Applications that span several blockchains also need a way for their contracts to coordinate, which the cross-chain smart contracts overview explains.
FAQ
Is a blockchain a decentralized computer?
In a sense, yes. A blockchain executes programs on many independent nodes and records the results in a shared state, although each computation is costly because the work is repeated.
Is decentralized computing the same as decentralized storage?
No. Computing runs programs, and storage keeps data available. Many applications use both.
Do decentralized applications still use traditional cloud services?
Often, yes. Interfaces, indexers, and other supporting services frequently run on conventional infrastructure, while the core logic and records live onchain.
