The Ethereum ecosystem is a massive and talented open source community and has produced a pantheon of valuable developer resources over the past several years. With a platform like Kauri, the community is now even using the innovation of Ethereum itself to vet, curate, and store high-quality content. From in-person training to technical tutorials to research forums, the knowledge bases below offer a wide range of resources for developers of all levels.
Academy provides an end-to-end Ethereum developer course that is self-paced and open year-round.
Crowdsourced resources for individuals seeking to learn, listen, or read about Ethereum.

An Ethereum client also provides interfaces to create transactions and mine blocks which is the key for any Ethereum transaction.
A scalable, standards-based, globally distributed cluster and API endpoint for Ethereum, IPFS, and other infrastructures.
A command line interface for running a full Ethereum node implemented in Go.
An Ethereum client developed by Parity Technologies using the Rust programming language.

Ok, so you’ve finally built your dapp or smart contract. But how do you know it was set up correctly and is safe from hackers? The security tools below will help ensure that your code is safe and follows all Ethereum development best practices.
A command line interface that uses a symbolic execution tool on smart contracts and binaries.
An analysis tool for smart contracts. Oyente utilizes a symbolic execution tool that works directly with EVM byte code without access to the high level representation (e.g Solidity).
A security analysis API for Ethereum smart contracts. MythX powers tools that bring security into the smart contract software development life cycle.
Public testnets on Ethereum offer a way for developers to test what they build without putting their creations on the main Ethereum network. You can obtain as much ETH as you want on testnets because testnet ETH doesn’t carry any monetary value. Similar to public testnets, local testnets are a place for you to test your software without pushing it public. Unlike public testnets, the local testnet software will only run on your computer/node and other users won’t be able to see it or interact with it. Below are the most used testnets to start testing on and links for requesting testnet ETH.
A proof-of-authority blockchain started by the Parity team. Test ether must be requested.
Proof-of-authority cross-client testnet, synching Parity Ethereum, Geth, Nethermind, Pantheon, and EthereumJS. This testnet is a community-based project, completely open-source.
A proof-of-work blockchain that most closely resembles Ethereum and allows you to easily mine faux-Ether.
If you want to start developing dapps, you’ll need front-end development skills. Below are the most popular front-end interfaces that will help you turn your dapp from an idea to a live Ethereum mainnet application. If you’re interested in doing backend/protocol work on Ethereum, you should have significant experience with Go, Rust, Java, .NET, Ruby, or Python.
A collection of front-end libraries that make writing decentralized application front-ends easier and more predictable. Drizzle provides a Redux library to connect a front-end to a blockchain.
Ethereum allows you to save variables or data in permanent storage. The storage platforms below are where all of the smart contract data lives. IPFS is the most commonly used storage system on Ethereum. Explore the platforms below to learn more about how storage on Ethereum works.
3Box is a secure and decentralized user data storage system. 3Box allows front-end web developers to keep user data on an open storage network instead of a centralized database server, browser localStorage, or the blockchain.
A decentralized peer-to-peer database on top of IPFS.
A distributed storage platform and content distribution service for the Ethereum Web3 stack.

Layer 2 Infrastructure & Scalability
Ethereum developers are continuously developing new and exciting ways to scale Ethereum. There are various solutions that developers are using to scale Ethereum, dapps, and protocols. Some of these include payments, state channels, sidechains, off-chain computation, and many more!
Payments & State Channels
Connext is an infrastructure layer that scales the Ethereum blockchain utilizing state channels.

An oracle is any such system that exposes external data for on-chain use. Without an oracle, a decentralized smart contract on Ethereum will only be able to perform operations with on-chain data. Oracles expand the potential use cases for smart contracts including insurance, finance and prediction markets.
The Chainlink network provides reliable tamper-proof inputs and outputs for complex smart contracts on any blockchain.
Rhombus divides oracles into two broad buckets: how the oracle is activated and how the oracle replies. The Rhombus API for running oracles has predictable, resource-oriented functions that enables you to connect a smart contract with real-world data.
Privacy and Confidentiality
Privacy around transactions and user identity has been at the heart of the crypto ecosystem since its inception. Many firms are developing mechanisms and protocols to guarantee privacy and confidentiality on Ethereum by utilizing mixers, zero-knowledge proofs, and other encryption tools.
