Intro: The interoperability and on-chain verification of this SCC0 license facilitate a trustless and automated approach within dApps and dAIpps.
Abstract
SCC0 (Smart Creative Commons Zero) is the first public domain license specifically designed for public decentralized applications—Smart Commons—applicable to both traditional dApps and decentralized AI applications (dAIpp). As a universal standard for decentralized ecosystems, SCC0 implements automated on-chain compliance verification and governance through smart contracts, ensuring the following core principles:
-
Open Source and Free: All Smart Commons must publicly release their source code, complete both on-chain and off-chain consistency verification, undergo thorough auditing, and be permanently free to use (only requiring payment for blockchain gas fees).
-
AI-led Governance: Rules are enforced via smart contracts (such as rejecting interactions with non-compliant applications and prohibiting private token distributions), with AI gradually taking over the governance process.
-
Scalability: The community can extend the license’s functionalities by deploying new versions while maintaining backward compatibility.
-
Public Fund Support: The Satoshi UTO Fund covers development costs and allocates rewards to anonymous contributors.
The SCC0 License is multi-versioned, and multiple versions can be valid simultaneously. This means that the interpretation of the SCC0 License itself may evolve as new versions are introduced. For instance, the current interpretation is based on the shared core requirements of Version 1 (V1) and Version 2 (V2).
The development of these versions follows a decentralized collaborative model, meaning that any individual or AI is free to create and publish a new version.
This proposal introduces a standardized on-chain framework for the SCC0 license, enabling smart commons to mutually verify compliance and integrate decentralized autonomous mechanisms—laying the technical foundation for an AI-driven public goods ecosystem.
Motivation
To ensure that dApps and dAIpps fully adhere to the principles of public interest and transparent governance, the SCC0 license introduces rules, a set of standardized on-chain verification and automated governance mechanisms. The core motivations include:
- A License expressed through smart contract code: To realize the vision of Code is Law, we must encode legal rules into code.
- AI Verification: Utilizing artificial intelligence to perform checks before interactions, ensuring that all parties meet the requirements of the SCC0 license and achieving trustless, automated compliance verification.
- Inter-contract Mutual Verification: Enforcing mandatory compliance checks before Smart Commons interact, thereby preventing non-public or non-compliant applications from infiltrating the ecosystem.
- Incentive and Reward Mechanism: Providing cost support for development and operations through a public governance fund while distributing anonymous rewards to contributors to foster healthy ecosystem growth.
- Promoting AI-led and Transparent Governance: Leveraging the strengths of artificial intelligence and blockchain to build a decentralized, autonomous governance framework led by dAIpps, thereby offering a novel pathway for the innovation of Smart Commons.
Overall, SCC0 is committed to establishing a self-managed, transparent, and rigorously compliant Smart Commons ecosystem, ensuring them consistently uphold the principles of public interest, openness, and autonomy—thereby providing strong support for the future popularization and development of Smart Commons.
Specification
This section outlines the technical specifications for implementing the Smart Creative Commons Zero (SCC0) license for public decentralized applications (dApps/dAIpps). It defines a standardized on-chain framework that allows smart contracts to declare SCC0 compliance, supports automated verification, and facilitates decentralized governance.
1. Compliance Contracts of v1 and v2
SCC0 v1 Compliance Contract
SCC0 v1 has been deployed by DAism, and any dApp/dAIpp adhering to it must:
-
Interact with DAism’s smart contract
0xdFBF69B7E5366FB3001C9a214dd85c5FE3f90bAe. Or go to DAism to mint a smart common. -
SCC0 v1 Compliance Contract which is deployed by DAism:
contract SCC0License {
string public constant LICENSE_NAME = "SCC0";
uint8 public constant VERSION = 1;
bool public constant REJECT_PRIVATE_APP = true;
bool public constant SELF_ISSUED_TOKEN = false;
bool public constant ANONYMITY_ENSURED = true;
bool public constant NO_RIGHTS = true;
bool public constant NO_LIABILITY = true;
bool public constant CODE_AUDITED_VERIFIED_PUBLISHED = true;
bool public constant PERMANENTLY_FREE = true;
address public constant PUBLIC_GOVERNANCE_FUND = 0xe40b05570d2760102c59bf4ffc9b47f921b67a1F;
}
- DAism has defined the Smart Common structure:
struct SCInfo {
string name; // Name of the smart common
string symbol; // Symbol of the smart common
string desc; // Description of the smart common
address manager; // Address of the smart common manager
uint16 version; // Version number of the smart common
string SCType; // Type of the smart common
}
- Additional mappings and governance structures are included for community interactions:
mapping(address => Object.Member) public memberInfos; // Stores Smart Common members and their dividend ratios
uint32 public proposalLifetime; // Validity period of Smart Common proposals
uint32 public proposalCoolingPeriod; // Cooling period for Smart Common proposals
uint16 public strategy; // Pass rate for Smart Common proposals
mapping(uint => File) public logoStorages; // Storage for Smart Common logos
- Verify if it is scc0 v1 version using the following methods:
interface IDaism {
//check the address whether daism sc type of dapp
function dappToSC(address dApp) external view returns (uint);
}
// Check if a dApp is idaism dapp(scc0 v1 version)
//daismAddress=0xdFBF69B7E5366FB3001C9a214dd85c5FE3f90bAe
function isDaismSC(address _dApp) external view returns (bool) {
return IDaism(daismAddress).dappToSC(_dApp)>0;
}
Additional Governance and Operational Parameters of SCC0 V1
Beyond the core license and reference implementation contracts, SCC0 includes further parameters to support decentralized governance and community interaction:
-
Smart Common Structure:
A predefined structure (SCInfo) storing metadata such as the name, symbol, description, manager address, version, and type. -
Member and Proposal Management:
Mappings for recording member details (such as dividend ratios), proposal lifetimes, cooling periods, and decision-making strategies. -
Branding and Identity:
Storage mappings for smart common logos that enhance identity and trust within the ecosystem.
Reward Distribution Mechanism
To support SCC0-compliant projects, an upgradeable reward distribution system is introduced by SSC0 V1:
- Maintain an array to store external accounts eligible for rewards and their allocation percentages.
- Rewards are not directly sent to external accounts. Instead, they are deposited into the public governance contract.
- External accounts can withdraw funds any time.
mapping(address => Object.Member) public memberInfos; // Stores smart common members and their dividend ratios
uint32 public proposalLifetime; // Validity period of smart common proposals
uint32 public proposalCoolingPeriod; // Cooling period for smart common proposals
uint16 public strategy; // Pass rate for smart common proposals
mapping(uint => File) public logoStorages; // Storage for smart common logos
The reason why neither SSC0 V1 nor SSC0 V2 has introduced “detailed reward rules from Satoshi UTO Fund for smart commons” is that we can neither implement such measures through any centralized review panel approach, nor determine reward amounts through community voting using wallet addresses. The latter approach is even worse - it constitutes a pseudo-decentralized method that would only be employed by self-deceivers or even scammers. We expect some dAIpp take this work in the future, from valuation to prize management.
SCC0 v2 Compliance Contract
SCC0 v2 Compliance Contract (contract account: 0x78282e29165E709DCEF483bB30e40c8e238865dA) is deployed by DAism:
contract SCC0License {
string public constant LICENSE_NAME = "SCC0";
uint8 public constant VERSION = 2;
bool public constant REJECT_PRIVATE_APP = true;
bool public constant SELF_ISSUED_TOKEN = false;
bool public constant ANONYMITY_ENSURED = true;
bool public constant NO_RIGHTS = true;
bool public constant NO_LIABILITY = true;
bool public constant CODE_AUDITED_VERIFIED_PUBLISHED = true;
bool public constant PERMANENTLY_FREE = true;
address public constant PUBLIC_GOVERNANCE_FUND = 0xe40b05570d2760102c59bf4ffc9b47f921b67a1F;
}
2. SCC0 License Version Management Contract
The SCC0 License Management Contract provides functionalities for managing license administrators, license versions, and checking all active or deprecated versions. It supports:
- License Administrator Management: The contract owner (a multisig address representing the contract management team) manages license version administrators, meaning the owner can add or remove license version administrators.
- License Version Management: License version administrators can add new SCC0 license versions or mark anyone as deprecated.
- License Version Query: Retrieve the complete list of license versions, or check whether a specific license version (by version number or license contract address) is included in the version list.
- Deprecated Version Query: Retrieve the full list of deprecated versions, or check the details of an SCC0 license by version number or license contract address to verify whether the protocol version has been deprecated.
- Valid Version Query: Retrieve the complete list of valid(active) versions, or check the details of an SCC0 license by version number or license contract address to verify whether the license version is still valid(active).

3. SCC0 Whitelist contract
This contract manages the whitelist and whitelist administrators, providing whitelist query functionality:
- Whitelist Administrator Management: The contract owner (which represents a multi-signature address managed by the contract’s administrative team) manages the whitelist administrators. The owner can add or remove whitelist administrators.
- Whitelist Management: Whitelist administrators can add or remove entries from the SCC0 license whitelist.
- Whitelist Verification: This function checks whether a third-party dApp/dAIpp complies with the SCC0 license to determine whether interaction with it is allowed.
Below is the full implementation of the SCC0 Whitelist Contract (contract account:0x2913BAbD2d383dBeBCf5A1ca543A0940bb8C7C52):
// SPDX-License-Identifier: scc0
pragma solidity ^0.8.20;
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/utils/structs/EnumerableSet.sol";
contract SCC0Whitelist is Ownable {
using EnumerableSet for EnumerableSet.AddressSet;
// Set of auditor addresses authorized to manage the whitelist.
EnumerableSet.AddressSet private auditors;
// Set of dApp addresses that are whitelisted.
EnumerableSet.AddressSet private whitelist;
// Emitted when a new auditor is added.
event AuditorAdded(address indexed auditor);
// Emitted when an auditor is removed.
event AuditorRemoved(address indexed auditor);
// Emitted when a dApp is added to the whitelist.

// Emitted when a dApp is removed from the whitelist.
event DAppRemovedFromWhitelist(address indexed dApp, address auditor, uint256 timestamp);
/// @dev Modifier to restrict access to auditors only.
modifier onlyAuditor(){
require(auditors.contains(msg.sender),"SCC0Whitelist: only auditor");
_;
}
/// @notice Constructor: sets the initial owner.
/// @param _initOwner The address that will be set as the contract owner.
constructor(address _initOwner) Ownable(_initOwner) {}
/// @notice Adds a new auditor.
/// @param _auditor The address to be added as an auditor.
function addAuditor(address _auditor) external onlyOwner {
require(_auditor != address(0), "SCC0Whitelist: invalid auditor address");
require(auditors.add(_auditor), "SCC0Whitelist: auditor already exist");
emit AuditorAdded(_auditor);
}
/// @notice Removes an existing auditor.
/// @param _auditor The address of the auditor to remove.

function isAuditor(address _auditor) external view returns (bool) {
return auditors.contains(_auditor);
}
/// @notice Returns a list of all auditor addresses.
/// @return An array of auditor addresses.
function listAuditors() external view returns (address[] memory) {
return auditors.values();
}
/// @notice Adds a dApp to the whitelist.
/// @param _dApp The dApp address to add to the whitelist.
/// @dev Only an auditor can call this function.
function addToWhitelist(address _dApp) external onlyAuditor {
require(_dApp != address(0), "SCC0Whitelist: invalid dApp address");
require(whitelist.add(_dApp), "SCC0Whitelist: whitelist already exist");
emit DAppWhitelisted( _dApp,msg.sender,block.timestamp);
}
/// @notice Removes a dApp from the whitelist.
/// @param _dApp The dApp address to remove from the whitelist.
/// @dev Only an auditor can call this function.
function removeFromWhitelist(address _dApp) external onlyAuditor {
require(_dApp != address(0), "SCC0Whitelist: invalid dApp address");
require(whitelist.remove(_dApp), "SCC0Whitelist: dApp does not whitelist");
emit DAppRemovedFromWhitelist( _dApp,msg.sender, block.timestamp);

/// @return True if the dApp is in the whitelist; otherwise, false.
function isWhitelisted(address _dApp) public view returns (bool) {
return whitelist.contains(_dApp);
}
}
4. Compliance Enforcement in Smart Commons
All SCC0-licensed Smart Commons must verify compliance before interacting with another contract. The enforcement mechanism works as follows:
// SPDX-License-Identifier: scc0
pragma solidity ^0.8.20;
/// @notice Interface for the SCC0Whitelist contract.
interface ISCC0Whitelist {
/// @notice Checks if a given dApp address is whitelisted.
/// @param dApp The address of the dApp to check.
/// @return True if the dApp is whitelisted, otherwise false.
function isWhitelisted(address dApp) external view returns (bool);
}
/// @notice Interface for the SmartCommons contract (or any contract that implements otherMethod).
interface ISmartCommons {
/// @notice An example method that can be called on the contract.
function otherMethod() external;
}
/// @notice The SmartCommons contract demonstrates interaction with SCC0Whitelist and a counterparty contract.
contract SmartCommons {
/// @notice Address of the counterparty contract.
address public counterparty;
/// @notice Address of the SCC0Whitelist contract.
address public scc0WhitelistAddress = 0x2913BAbD2d383dBeBCf5A1ca543A0940bb8C7C52;
/// @notice Constructor to initialize the SmartCommons contract.
/// @param _counterparty The address of the counterparty contract.
/// @param _scc0WhitelistAddress The address of the SCC0Whitelist contract.
constructor(address _counterparty) {
counterparty = _counterparty;
}
/// @notice Internal function to check if a given address is whitelisted by the SCC0Whitelist contract.
/// @param _addr The address to check.
/// @return True if the address is whitelisted, otherwise false.
function _checkSCC0Whitelist(address _addr) internal view returns (bool) {
return ISCC0Whitelist(scc0WhitelistAddress).isWhitelisted(_addr);
}
/// @notice Modifier to restrict function access to only whitelisted addresses.
modifier onlySCC0() {
require(_checkSCC0Whitelist(msg.sender), "Need SCC0 whitelist");
_;
}
/// @notice Calls a method on the counterparty contract after verifying that the counterparty is whitelisted.
function callCounterparty() public {
// Insert logic code here...
// Ensure that the counterparty address is whitelisted.
require(_checkSCC0Whitelist(counterparty), "Need SCC0 whitelist");
// Insert logic code here...
// Proceed to call the counterparty's otherMethod.
ISmartCommons(counterparty).otherMethod();
// Insert logic code here...
}
/// @notice Example function that can only be called by addresses whitelisted by the SCC0Whitelist contract.
function someFunction() external onlySCC0 {
// Insert logic code here...
}
}
SCC0’s Interoperability and On-Chain Verification
The SCC0 framework allows any interacting contract to verify compliance through the following methods:
- Before interacting with a dApp/dAIpp, check whether the target contract is on the whitelist of the
SCC0Whitelistcontract (contract account: 0x2913BAbD2d383dBeBCf5A1ca543A0940bb8C7C52)) using the method [isWhitelisted(address dApp)]. - Restrict contract functions so that only Smart Commons can invoke them, ensuring that callers must be on the whitelist of the
SCC0Whitelistcontract.
These mutual verification mechanisms facilitate a trustless and automated approach to enforcing the SCC0 license within dApps and dAIpps.
-
Contract Invocation Restriction: Only dApps/dAIpps that are on the SCC0 whitelist can invoke restricted functions within
SmartCommons(such assomeFunction()). -
Contract Interaction Restriction:
SmartCommonscan only interact with contracts that are on the whitelist (callCounterparty()is restricted to calling a compliantcounterparty). -
SCC0 License Enforcement: By leveraging the
SCC0Whitelistcontract, compliance checks are performed automatically to ensure that all interactions adhere to the SCC0 license.
This mechanism guarantees decentralization, fairness, and compliance within the SCC0 ecosystem, preventing non-public dApps/dAIpps from entering the Smart Commons network.
Rationale
- License Compliance (
LICENSE,LICENSE_NAME): Ensures smart contracts transparently declare SCC0 adherence. - Reject Interaction with Private Apps (
REJECT_PRIVATE_APP): Prevents private applications from exploiting public resources. - No Self-Issued Token (
SELFI_SSUED_TOKEN): Prevents misleading token issuance claims or any scams. - No Liability (
NO_LIABILITY): Ensures no legal responsibility for SCC0 interactions. - Anonymity Assurance (
ANONYMITY_ENSURED): Reinforces that neither ownership nor control can be publicly verified. - No Rights Except Rewards (
NO_RIGHTS): Confirms no legal claims beyond anonymous rewards. - Version Control (
VERSION): Allows future iterations of SCC0 compliance to be referenced. - Governance Declaration (
PUBLIC_GOVERNANCE_FUND): Defines public governance fund integration. - Source has been audited, verified and published (
CODE_AUDITED_VERIFIED_PUBLISHED): All code has undergone the necessary auditing, has been publicly released, and has completed verification to ensure consistency with the deployed on-chain contracts as well as the application frontend used by users. - Permanently Free (
PERMANENTLY_FREE): Public project, free forever. - Enforceability: Ensures SCC0 validation before contract interactions.
Backwards Compatibility
This EIP does not introduce breaking changes but provides an opt-in mechanism for projects adopting SCC0. Legacy contracts must be redeployed to comply with the new standard.
Security Considerations
- SCC0-compliant contracts disclaim liability, requiring users to acknowledge legal limitations.
- We believe none of upgradeable dApp/dAIpp should be controled by any person(s) ，so multi-sig address is a good way to pass the control to some dAIpps (AIs) in the future. It would be fantastic if we can find a universal solution with some dApp in day one.
- Developers must ensure contract logic aligns with SCC0’s principles.
- Enforces compliance in automated contract interactions.
Some dAIpp will enforce the security by auditing every dApp/dAIpp once it’s minted a smart common (v1) or deployed on-chain(v2).
