A Primer on Blockchain and Hedera: An Intro Through Terms

What if you could build in Web3 without writing a single smart contract? Learn how Hedera lets you build powerful dApps using just JavaScript.

#1about 2 minutes

Understanding the barriers created by Web3 jargon

Web3 terminology can be confusing and create barriers to entry, so it's important to start with the basics to feel safe while learning.

#2about 2 minutes

Defining transactions and distributed ledger technology

Distributed ledger technologies are built on transactions, which are defined by their speed (TPS), finality, and immutability on the network.

#3about 2 minutes

Tracing the evolution of the web to Web3

The web has evolved from a static, read-only medium (Web1) to a user-generated platform (Web2) and now to a decentralized, user-owned internet (Web3).

#4about 4 minutes

Exploring Hedera's unique approach as a DLT

Hedera is a public permissioned DLT that is moving towards being permissionless, featuring the energy-efficient HBAR token and a carbon-negative network.

#5about 3 minutes

Explaining white papers and network layers

Networks are defined by a white paper and structured into layers, with Layer 1 providing base security and Layer 2 solutions offering scalability.

#6about 3 minutes

Comparing different network consensus mechanisms

Networks achieve agreement through consensus mechanisms like proof of work or proof of stake, while Hedera uses the efficient hashgraph algorithm.

#7about 1 minute

Understanding data structures and network integrity

Blockchains use Merkle trees to structure data immutably, and while some networks can fork due to disagreements, Hedera is designed to prevent this.

#8about 1 minute

Exploring tokens, fungibility, and decentralized finance

Tokens enable microtransactions and gated content, with fungible tokens being interchangeable, forming the basis for decentralized finance (DeFi) applications.

#9about 2 minutes

Understanding testnets and cryptographic security

Developers use testnets for safe experimentation before deploying to a mainnet, securing assets with public/private keys and specific cryptographic algorithms.

#10about 2 minutes

Achieving interoperability with the EVM

Interoperability allows data and assets to move between networks, with Hedera's EVM compatibility enabling developers to port Ethereum-based applications.

#11about 4 minutes

Using smart contracts and developer tools on Hedera

Developers can use wallets to interact with the network and build with Solidity smart contracts or use Hedera's SDKs with familiar tools like Truffle and Hardhat.
