Intelligent Contracts

Intelligent Contracts Compared with Traditional Smart Contracts

Traditional smart contracts normally require deterministic inputs and execution. Intelligent Contracts can use variable AI and web results. GenLayer adds validation rules and consensus for this variable work.

Scope and decision boundary

An Intelligent Contract keeps blockchain state deterministic. It contains variable AI and web work inside controlled non-deterministic blocks.

The contract must define how validators assess a proposed result. This rule is part of the application design, not an optional implementation detail.

This guide defines the technical controls for this subject. It does not treat a model response as proof.

Start with the decision boundary. Identify the permitted inputs, the required output, and the state change that can follow validation.

This subject also connects to The Change from Smart Contracts to Intelligent Contracts and Intelligent Contracts and Autonomous Commerce. Read those guides together when the decision crosses trust, retrieval, or execution boundaries.

What changes in practice

Both contract types keep deterministic state on a blockchain.

Treat this point as a design requirement. Record the input and the expected result before implementation.

Intelligent Contracts contain variable operations in special blocks.

Connect this point to a visible contract state. A reviewer must be able to inspect the resulting behavior.

Validators can compare meaning or apply custom validation criteria.

Test this point with normal, invalid, unavailable, and disputed inputs. Do not test only the successful path.

Implementation in practice

Use deterministic code for calculations that do not need AI or web access.

Document the owner, input, output, failure response, and test evidence for this control.

Use an Intelligent Contract when the decision requires language or changing external data.

Document the owner, input, output, failure response, and test evidence for this control.

Document the additional cost and latency of each variable operation.

Document the owner, input, output, failure response, and test evidence for this control.

Verification procedure

Use this procedure before deployment. Keep the test evidence with the contract version and network configuration.

01State the decision in one sentence. Identify the person or system that uses the result.
02List each deterministic input, non-deterministic input, external source, and model dependency.
03Define the accepted output type, required fields, value limits, and failure states.
04Test correct input, malformed input, unavailable evidence, stale evidence, and conflicting evidence.
05Test validator agreement, validator disagreement, leader rotation, appeal, and finality where applicable.
06Confirm that no state change occurs before the contract obtains an acceptable result.
07Record the source, network, transaction state, and validation outcome for operational review.

Design review questions

A reviewer must answer these questions before the contract handles a high-impact decision.

Can fixed code complete this task without AI or web access?
What evidence is necessary, and which source is authoritative for that evidence?
What result must a validator reject?
What does the application do when the result is partial or unavailable?
Can a user distinguish an accepted result from a finalized result?
What data must remain private?
Which dependency can cause several validators to fail at the same time?

Evidence record

Keep enough evidence to reproduce the application decision. Do not store private input in a public contract record.

Field 1: Contract version and network identifier
Field 2: Transaction identifier and current transaction state
Field 3: Source identifier, retrieval time, and content version when available
Field 4: Model task, required output structure, and validation criteria
Field 5: Validator outcome, disagreement state, and appeal state
Field 6: Final application action and the authority that approved it

Operational monitoring

Deployment is not the end of verification. Monitor the complete decision path and investigate changes in behavior.

Measure source, model, and network availability as separate signals.
Measure response time for retrieval, model execution, validation, acceptance, and finality.
Record rejected proposals, validator disagreement, leader rotation, and failed retries.
Track source format changes and model configuration changes that can alter output.
Review appeals and overturned results for weak criteria or missing evidence.
Repeat the validation suite after a contract, prompt, source, model, or network change.

Release criteria

Release the contract only when the team can explain each input, validation rule, state change, failure response, and authority boundary.

The test suite must include evidence failure and validator disagreement. A successful example does not prove safe behavior.

The interface must show the correct transaction state. It must not describe an accepted result as final before the finality process ends.

The operating team must have a response procedure for provider failure, source change, disputed results, and contract defects.

Limits

Intelligent Contracts are not a replacement for all deterministic contracts.
A wider input surface requires more testing and stronger failure handling.

Check the source pages again before production deployment. Protocol, network, and software requirements can change.
