A decentralized, distributed ledger technology (DLT) that cryptographically links data records (blocks) to create an immutable, transparent chain of validated transactions.

Blockchain is a decentralized, distributed ledger technology (DLT) that securely records transactions across a peer-to-peer network. Each data record, or *block*, is cryptographically linked to the previous one via a unique hash, ensuring chronological consistency and immutability. Once a transaction is validated by network consensus (e.g., Proof-of-Work or Proof-of-Stake), it is permanently added to the chain; no single entity can alter the record retroactively. This structure eliminates the need for a central authority (like a bank), driving trust and transparency across various applications: Bitcoin uses it for peer-to-peer currency, while enterprises (like IBM) leverage it for supply chain tracking and digital identity management.

## Recent Public Talks and Demos

### [How to launch your AI agent to a marketplace and monetize your agent](https://boston.aitinkerers.org/talks/rsvp_kb4CR180sSY)

Using the Dunback Meadow marketplace as example, I will demonstrate with specific code, how AI developers could monetize their AI agents in a marketplace: either launch their pre-developed agent on the marketplace, or use the platform to create an agent and launch it right after creation.

### [Collaborating Agents](https://toronto.aitinkerers.org/talks/rsvp_MrhTOEptmUo)

In a world where AI agents increasingly drive decision-making, trust is paramount. This demo explores teams of collaborating agents, and how blockchain technology can address the trust problem in AI. By leveraging blockchain's decentralized and immutable ledger, we can ensure transparency, accountability, and security in AI operations. Discover how these technologies converge to create a future where AI decisions are transparent and verifiable, fostering trust between technology and humans.
