Checkpoint System

OPSource utilizes a checkpoint system to ensure the integrity and consistency of the blockchain. This system involves periodically anchoring the state of the blockchain to the Bitcoin blockchain, providing a secure and tamper-proof record of all transactions and smart contract executions.

• Checkpoint Frequency: Checkpoints are created every 1000 blocks
• Checkpoint Data: Includes the current state of the blockchain, including all transactions and smart contract executions
• Anchoring Mechanism: Checkpoints are anchored to the Bitcoin blockchain using OP_RETURN transactions

In Progress:

• 🔄 Lightning Network: Integration with LDK (10% complete)
• 🔄 RGB Asset Transfer: Full transfer functionality (60% complete)
• 🔄 Web5 Extensions: Advanced DID capabilities and schema repository (30% complete)
• 🔄 API Layer: RESTful API implementation (85% complete)

Next Major Release:

Beta v0.6.0 expected on March 15, 2025, will include expanded API documentation and extended test coverage.

Example Use Cases

Discrete Log Contracts (DLC)

// Create an oracle
let oracle = dlc::Oracle::new("Weather Oracle");
let oracle_pubkey = oracle.public_key();

// Create a DLC with specified outcomes
let outcomes = vec![
    ("sunny".to_string(), 1_000_000), // 1M sats if sunny
    ("rainy".to_string(), 500_000),   // 500K sats if rainy
];

// Create the contract
let contract = dlc::create_contract(
    wallet,
    outcomes,
    &oracle_pubkey.to_hex(),
).await?;

// Oracle attests to the outcome
let event = dlc::OracleEvent {
    id: "weather-2023-04-01".to_string(),
    outcome: "sunny".to_string(),
};
let attestation = oracle.attest(&event);

// Execute the contract based on attestation
let txid = dlc::execute_contract(
    wallet,
    &contract,
    attestation,
).await?;

// Check contract status
let status = dlc::get_contract_status(wallet, &contract).await?;

DAO Creation and Management

// Create a new DAO configuration
let dao_config = dao::DAOConfig {
    name: "OPSource Governance DAO",
    governance_type: "multisig",
    voting_threshold: 0.66, // 66% required for proposal approval
    voting_period_days: 3,
    members: vec!["member1".to_string(), "member2".to_string()],
};

// Initialize the DAO
let dao = dao::create_dao(wallet, dao_config).await?;

// Create a new proposal
let proposal = dao::create_proposal(
    dao,
    "Increase Voting Threshold",
    "Proposal to increase voting threshold to 75%",
    json!({
        "action": "update_parameter",
        "parameter": "voting_threshold",
        "value": 0.75
    }),
).await?;

// Cast a vote
dao::vote(dao, &proposal.id, "member1", dao::Vote::Yes).await?;

// Check proposal status
let status = dao::get_proposal_status(dao, &proposal.id).await?;

RGB Asset Issuance

// Issue a fungible asset on RGB
let asset = rgb::issue_asset(
    wallet,
    "My Token",
    "TKN",
    1_000_000, // 1M units
    "This is a sample token issued on RGB",
)?;

RSK Smart Contract Interaction

// Interact with an RSK smart contract
let contract_address = "0x1234...";
let result = rsk::call_contract(
    wallet,
    contract_address,
    "balanceOf(address)",
    vec![my_address],
)?;
