Describe briefly how Blockchain works? Explain its relevance in
the context of the sharing economy.
Blockchain is a distributed ledger technology that enables secure, transparent, and reliable transactions. It works by recording data in a decentralized, distributed, and immutable manner. This makes it suitable for applications in the sharing economy, where users can trust that their transactions are secure and reliable. Blockchain can help reduce transaction costs and enable trustless transactions between users. It can also help to create smart contracts, which can automate and secure transactions, making them more efficient and secure.
Blockchain is a decentralized digital ledger technology that securely records transactions across multiple computers in a way that ensures the data cannot be altered retroactively without the consensus of the network. Each transaction is grouped into a block, which is then linked to the previous block, forming a chronological chain. This structure ensures transparency, security, and immutability, as any changes would require consensus from the majority of network participants.

### Relevance in the Sharing Economy:

1. **Trust and Transparency**: In the sharing economy, trust is crucial as users often engage with strangers. Blockchain provides a transparent and tamper-proof record of transactions, enhancing trust among participants.

2. **Decentralization**: Traditional sharing platforms often rely on intermediaries (like Airbnb or Uber) to facilitate transactions. Blockchain allows for peer-to-peer transactions, reducing reliance on these middlemen and potentially lowering costs.

3. **Smart Contracts**: These are self-executing contracts with the terms of the agreement directly written into code. In the sharing economy, smart contracts can automate agreements (e.g., rental terms), ensuring that conditions are met before transactions are finalized, which increases efficiency and reduces disputes.

4. **Identity Verification**: Blockchain can provide a secure method for verifying user identities, which is essential for building trust in sharing economy platforms where users may not know each other.

5. **Microtransactions**: Blockchain allows for the facilitation of microtransactions, enabling users to engage in smaller-scale sharing without high transaction fees, making it
