What You Should Know About Web3: A Primer For Developers

Web3 defitinion

Web3 is a set of emerging tools and technologies for building decentralized, distributed applications. This includes tools for file storage, data storage, name resolution, identity, compute, and even code hosting

Current state of web3

Right now what we call web3 is mostly centered on public blockchains like Ethereum

Example of decentralised storage

decentralized file storage solutions like IPFS and Arweave , and decentralized data storage tools like Ceramic and OrbitDB .

Example of app layer for web3

emerging app layer for web3, which would be something like ENS for name resolution, protocols like Ceramic

Example of identity layer for web3

I would also add to this toolkit ZK tools , or zero-knowledge tools, which use cryptography in interesting ways that preserve user privacy.

Attributes:

• Permissionless . Anyone on the network can call the functions that you have exposed on your contracts at any time.
• Immutable . Once you’ve deployed a contract, you can’t change it.
• Costly . The Ether asset is required to pay for storage and computation.
• Deterministic . This means that we can know, based on state at time zero, what the following state at time one is going to
• Adversarial . This one combines all the previous properties in some ways, because the value you store in a smart contract is its own sort of bug bounty.

Why should you learn about web3?

Even if you don’t want to become a smart contract programming expert, spending a little time with Solidity in this interesting paradigm is a great way to stretch yourself and become a better programmer.
