🌐Blockchain

If you have knowledge about blockchain technology, you can skip this section. Otherwise, you will find a basic conceptual understanding without technical depth.

Without delving into deep technical aspects, we focus on two concepts:

• Blockchain technology (referring to its public nature and not to private ones) refers to a decentralized database managed by a network of nodes without a central point of control.

• Web3: understood as the evolution of web2, enabling users to read the web, write, and own digital assets.

About blockchain, instead of being controlled by a single centralized server, multiple nodes manage it, reducing the likelihood of a single point of failure and control. Each identity has a unique identifier on this (an address) and can prove ownership of this identifier using a private key.

To clarify: imagine an island (blockchain) with multiple houses (addresses). To ensure that what happens in that house and what is stored there belongs to me and corresponds to my actions, I have the key (private key) that opens it and can demonstrate this.

Each blockchain has a native asset (cryptocurrency) that incentivizes node operation and is used to pay for transactions. In the same example: transactions on the island are paid in the local currency, and everyone who registers them receives rewards for their work.

When referring to programmable blockchains, Ethereum is a key example. It functions as a decentralized database and supports smart contracts, allowing functions to be executed without intermediaries while ensuring high security and immutability. What is written in this database is set in stone due to its immutable nature.

Interacting with blockchain can be complex and costly, but continuous advancements are improving user experience and reducing costs. For example, MPC wallets use technology that allows logging in with familiar social accounts (e.g., Google, LinkedIn) while providing the security and benefits of web3.

Focusing on Prutopia, using the Polygon blockchain (which benefits from Ethereum's features), individuals will create their work identities stored in a decentralized database. This ensures they have sole control over their identities, and counterparts can validate their records to ensure authenticity. This global database built on the internet allows seamless interoperability across various online sites and platforms.
