Blockchains

Bitcoin

Bitcoin is a digital or virtual currency created in 2009 that uses peer-to-peer technology to facilitate instant payments.

• Bitcoin - A father of all blockchains. Bitcoin development on Github
• Script - Writing smart contracts on Bitcoin is possible, however, not that simple
• Lightning Network - L2 scaling solution for Bitcoin protocol, aimed to solved scalability problem
• Bitcoin fees calculator - Bitcoin fees calculation

Bitcoin Libraries and Tools

• bitcoinjs - A javascript Bitcoin library for node.js and browsers

Bitcoin Wallets:

• Exodus - Popular bitcoin hot wallet

Ethereum

Ethereum is a blockchain platform with its own cryptocurrency, called Ether (ETH) or Ethereum, and its own programming language, called Solidity.

Ethereum Basics

• Ethereum Book - best way to dive deep into Ethereum ecosystem and learn about all key concepts, runtime and EVM
• Solidity - Ethereum native language to write smart contracts
• Vyper - Ethereum another native language for smart contracts development. Used less frequently than solidity
• EVM - Ethereum turing-complete virtual machine, runtime environment to execute smart contracts
• Ethereum Gas Station - Ethereum gas price estimator to predict gas consumption for smart contracts execution
• Polygon - L2 scaling solution for Ethereum. Most widely used as of 2021
• Arbitrum - Another L2 scaling solution for Ethereum
• Etherscan - Ethereum blockchain explorer

Ethereum 2

Long term goal of switching from Proof of Work to Proof of Stake

• Beacon Chain - Beacon chain is a parallel Eth chain that supports Proof of Stake consensus
• Sharding - More of upcoming Ethereum sharding

Ethereum Libraries and tools

Javascript:

• web3js - One of the best libraries to interact with Ethereum network through JSON-RPC
• etherjs - Another great library to use with Ethereum
• ganache-cli - Ganache command line utility tool

Python:

• web3py - Python library for Ethereum inspired by web3js
• brownie - Python-based development and testing framework for smart contracts on Ethereum
• py-evm - Python implementation of EVM

Tools:

• Hardhat - Modern Ethereum development environment
• Truffle - Another Ethereum development environment
• Ganache - Ethereum simulator for local(not only) development

Ethereum Tutorials:

• Cryptozombies - Beginner guide to Ethereum development using smart contracts
• Ethereum Dev Speed Run - An article with everything you need to start with Ethereum
• Solidity by example - Intro to Solidity with simple examples

Ethereum Wallets:

• Metamask - Most popular Ethereum hot wallet
• Exodus - Another popular Ethereum hot wallet

Cardano

Cardano is a decentralized blockchain platform launched in 2017 by Ethereum co-founder Charles Hoskinson. Smart contracts launched in September 2021 and infrastracture is WIP.

Cardano basics

• Cardano smart contracts - what are cardano smart contracts
• Marlowe - native language to write smart contracts on Cardano

Web3

Modern applications that are running on blockchains.

DeXes

Ethereum Based

• Uniswap - Most popular decentralized exchange built on Ethereum. Allows to exchange ERC20 tokens
• Sushiswap - Uniswap fork that is also quite popular for ERC20 swaps
• PancakeSwap - Decentralized exchange running on Binance Smart Chain
• 1inch - Another exchange aggregator that scans decentralized exchanges to find the lowest cryptocurrency prices for traders

Algorand Based

• TinyMan - First DeX running on Algorand Blockchain
