Blockchain

Geth

A command line interface for running Ethereum node implemented in Go Language.

Hardhat

A development environment to compile, deploy, test, and debug Ethereum software. It helps developers manage and automate the recurring tasks that are inherent to the process of building smart contracts and dApps. 

Hyperledger

A global enterprise blockchain project that offers the necessary framework, standards, guidelines, and tools to build open-source blockchains and related applications for use across various industries.

Hyperledger Fabric

An open source, permissioned blockchain framework. It is a modular, general-purpose framework that offers unique identity management and access control features, which make it suitable for a variety of industry applications such as track-and-trace of supply chains, trade finance, loyalty and rewards, as well as clearing and settlement of financial asset

Layer 1

A set of solutions that improve the base protocol itself to make the overall system a lot more scalable. There are two most common layer-1 solutions, and these are the consensus protocol changes as well as sharding.

Layer 2

Refers to a secondary framework or protocol that is built on top of an existing blockchain system. The main goal of these protocols is to solve the transaction speed and scaling difficulties that are being faced by the major cryptocurrency networks.

MetaMask

A software cryptocurrency wallet used to interact with the Ethereum blockchain. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications

Mist

Ф fully synchronized wallet, which means that you have to download the entire Ethereum blockchain, which exceeds 1 TB. Mist is an Electron framework-based application that is used for the management of Ethereum wallet and Ethereum applications.

MythX

Automatically scans for security vulnerabilities in Ethereum and other EVM-based blockchain smart contracts. MythX's comprehensive range of analysis techniques—including static analysis, dynamic analysis, and symbolic execution—can accurately detect security vulnerabilities to provide an in-depth analysis report. 

NFTs

Stand for a non-fungible token. A financial security consisting of digital data stored in a blockchain, a form of distributed ledger. The ownership of an NFT is recorded in the blockchain, and can be transferred by the owner, allowing NFTs to be sold and traded. NFTs typically contain references to digital files such as photos, videos, and audio.

OpenZeppelin

A platform for building secure decentralized applications.

P2P Network

A distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.

Private Blockchain

Permissioned blockchains controlled by a single organization. In a private blockchain, the central authority determines who can be a node.

Polkadot

An open source, blockchain platform and cryptocurrency. It provides interconnectivity and interoperability between blockchains, by enabling independent chains to securely exchange messages and perform transactions with each other without trusted third-party.

Populus

A smart contract development framework for Ethereum. According to their repo, they're the framework "with the most cute animal pictures".

PoS

A cryptocurrency consensus mechanism that requires you to stake coins, or set them aside, to be randomly selected as a validator.

PoW

Uses randomly selected miners to validate transactions. Proof of Work (POW) uses a competitive validation method to confirm transactions and add new blocks to the blockchain.

Public Blockchain

Completely open and follow the idea of decentralisation to the T. Bitcoin and Ethereum are both examples of public blockchains. Anyone in the network can access the chain and add blocks.

Quorum

An open source blockchain protocol specially designed for use in a private blockchain network, where there is only a single member owning all the nodes, or, a consortium blockchain network, where multiple members each own a portion of the network. 

Remix

An open-source web and desktop application. It fosters a fast development cycle and has a rich set of plugins with intuitive GUIs. Remix is used for the entire journey of contract development as well as act as a playground for learning and teaching Ethereum.

Replit

A coding platform that lets you write code and host apps. It also has many educational features built-in, making it great for teachers and learners too.

Ripple

A blockchain-based digital payment network designed to serve the needs of the financial services industry. 

Smart Contract

A program stored on a blockchain that runs when predetermined conditions are met. Typically, smart contracts are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without an intermediary’s involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.

SmartPy

A high-level smart contract library in Python that offers a simple, intuitive and powerful syntax, enabling developers to easily define Michelson smart contracts for the Tezos blockchain.

Solana

A public blockchain platform designed to host scalable applications which are decentralized. Its native cryptocurrency is SOL. Like the rest of the world’s most popular blockchains, Solana has a smart contract functionality.
