Automated License Enforcement

The core feature is the encoding of license terms directly into immutable smart contract logic. This automates compliance checks, such as verifying payment, usage limits, or authorized addresses, without manual intervention. Key functions include:

• Automated minting of license tokens upon payment.
• Real-time validation of license status for each function call.
• Automatic revocation upon expiration or breach of terms.

Licenses are represented as non-fungible tokens (NFTs) or soulbound tokens (SBTs), providing a transparent and verifiable record of ownership and terms. This creates an immutable audit trail for:

• Proof of purchase and license validity.
• Transfer history and authorized sublicensing.
• Royalty distribution to original developers on secondary sales.

Smart contracts enforce fine-grained permissions based on license type. This allows for tiered pricing models and feature gating, such as:

• Function-level restrictions: Premium features are locked behind specific license tiers.
• Time-based access: Licenses can expire after a set period (e.g., monthly subscription).
• Usage-based limits: Capping the number of API calls or transactions.

Payment for licenses is handled programmatically, with funds instantly and transparently routed according to pre-defined rules. This enables:

• Instant settlement to developers upon license minting.
• Automated royalty splits to multiple stakeholders (e.g., protocol treasury, original creators).
• Transparent fee structures visible on-chain, eliminating opaque billing.

ALE smart contracts are designed as composable primitives that can be integrated into larger DeFi and application ecosystems. Examples include:

• Bundling licenses as collateral in lending protocols.
• Using license NFTs as gatekeepers for DAO governance or token-gated content.
• Automating license provisioning within CI/CD pipelines or developer platforms.

While automated, systems often include governance-controlled parameters for edge cases and evolution. This may involve:

• Pausable functions to halt enforcement in case of critical bugs.
• Governance voting to update fee structures or license terms.
• Multi-signature timelocks for secure administrative actions, balancing automation with necessary oversight.

ALE enables developers to deploy software with embedded license terms directly into smart contracts. This allows for pay-per-use models, time-based subscriptions, and feature-gated access. For example, a developer can create an API where each call requires a valid, non-expired license NFT, with payments streaming to the developer's wallet automatically.

Companies can distribute proprietary Software Development Kits (SDKs) or libraries with enforceable commercial terms. The ALE contract can:

• Verify a user's license before allowing compilation or deployment.
• Enforce royalty payments on derivative works.
• Automatically revoke access if subscription payments lapse, preventing unauthorized use in production.

ALE smart contracts can codify complex Business-to-Business (B2B) agreements. Use cases include:

• Seat-based licensing: Minting a license NFT for each employee account.
• Usage tiering: Automatically upgrading a plan and billing based on API call volume or data processed.
• Compliance auditing: Providing a transparent, immutable record of license issuance and usage for all parties.

Projects can adopt a dual-licensing model where the core code is open source (e.g., under GPL), but commercial features or exemptions are gated behind an ALE-managed license. This allows communities to build freely while creating a sustainable revenue stream for core maintainers through automatically enforced commercial licenses.

In-game assets, tools, or mods created by developers or players can be licensed for use. An ALE system can manage:

• Revenue sharing for asset marketplaces.
• Rental mechanics where a rare weapon or skin is licensed for a 24-hour period.
• Resale royalties that are automatically enforced on secondary market transactions.

ALE does not replace traditional law but can integrate with it. Lex Proof tokens or signed attestations can link an on-chain license to an off-chain legal contract. This creates a hybrid enforcement system where breach of smart contract terms provides auditable evidence for dispute resolution in conventional courts, strengthening the legal standing of the license.

ALE systems use smart contracts to act as automated gatekeepers for software libraries or protocols. Key components include:

• License Tokens: NFTs or fungible tokens that represent a right to use the software.
• Verification Logic: On-chain checks that validate a user's token ownership before granting access to a function or repository.
• Automated Compliance: Terms like payment schedules, usage limits, or attribution are enforced without manual intervention.

ALE allows open-source developers to adopt dual licensing or commercial licensing models. Projects like Uniswap v4 with its hooks, or various NFT projects with commercial rights, can use ALE to require a license for commercial deployment. This creates a sustainable funding model while keeping the code publicly auditable.

Implementation typically involves a modifier function in a smart contract. Before executing a protected function, the contract checks the caller's balance of a specific license token via the ERC-721 or ERC-1155 standard. Failed checks revert the transaction. Licenses can be time-bound (subscription) or perpetual, with renewal logic handled on-chain.

ALE addresses critical gaps in traditional software licensing:

• Transparent and Trustless: License terms and ownership are publicly verifiable on the blockchain.
• Reduced Friction: Automated collection eliminates manual invoices and legal overhead.
• Granular Control: Licenses can be tied to specific addresses, block numbers, or usage metrics.
• Composability: License tokens can be integrated into other DeFi or DAO governance systems.

ALE is closely related to on-chain royalty enforcement for NFTs, where a smart contract automatically routes a percentage of a secondary sale to the original creator. Both concepts use smart contracts to autonomously enforce financial terms attached to digital assets, shifting enforcement from legal threats to cryptographic certainty.

A smart contract license is a set of permissions and restrictions encoded directly into a smart contract's logic or referenced via a standard like the Blockchain Software License (BSL). It defines the legal and technical rules for using, modifying, or forking the underlying code. ALE systems are the automated enforcement layer for these on-chain licenses.

A common license model where exclusive commercial rights are granted to a founding team for a fixed period (e.g., 2-4 years), after which the code becomes freely usable. ALE automates this transition by enforcing the time-lock—preventing unauthorized forks before expiry and automatically releasing the code into the public domain or a permissive license afterward.

Forking is the act of creating a new, independent version of a blockchain or smart contract by copying its source code and state. ALE directly governs forking rights by using on-chain checks to permit or deny the deployment of forked contracts based on the license terms (e.g., allowing forks only after a time-lock expires or if a fee is paid).

A smart contract architecture where user funds and state are held in a permanent proxy contract, while the logic is stored in a separate, changeable implementation contract. ALE is often integrated at the proxy level, checking license compliance (like expiry) before allowing any call to be forwarded to the logic contract, thus protecting the entire application.

• On-Chain Enforcement: Rules are validated by the blockchain's consensus (e.g., a require() statement in a proxy). This is automatic, immutable, and trustless but can be rigid.
• Off-Chain Enforcement: Relies on legal contracts and manual litigation. ALE shifts enforcement on-chain, making it programmatic and self-executing, reducing reliance on traditional legal systems for technical violations.

The practice of applying different license terms to distinct components of a protocol. For example, core vault logic may have a time-locked license, while peripheral contracts are MIT-licensed. ALE systems can be designed to enforce these modular rules selectively, allowing for nuanced commercial strategies within a single decentralized application.
