Decentralized AI Marketplaces

Platforms like ModelDAO enable peer-to-peer AI model trading, allowing developers to monetize training data and models without relying on centralized cloud providers.

// Example: Web3 AI Model Market
const modelRegistry = new SmartContract('ModelRegistry');
modelRegistry.deploy('ai-models-v2');

function tokenizeModel(model) {
  return new NFTToken({
    name: `${model.name} AI`,
    metadata: {
      description: model.description,
      training_data: model.dataHashes,
      accuracy: model.stats.accuracy,
    },
    owner: model.owner.address
  });
}

Self-Sovereign Identity

Protocols like OpenID Connect and Verifiable Credentials are becoming mainstream, allowing users to control their digital identities without centralized authorities.

Gasless Transactions

Bundlers and paymasters in layer-2 solutions now enable "zero-fee" transactions for users by charging transaction costs to app developers or DAOs.
