Solidity is a contract-oriented, high-level language for implementing smart contracts. It was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM). It is statically typed, supports inheritance, libraries and complex user-defined types among other features. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets.

It uses concolic analysis, taint analysis and control flow checking to detect a variety of security vulnerabilities. If you a smart contract developer who wants convenience and comprehensive results, you should be using MythX, our next-gen smart contract security API that integrates with Truffle Framework and other development environments.

These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.

It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems. To write your custom contracts, import ours and extend them through inheritance.

With OpenZeppelin, you can build distributed applications, protocols and organizations. It is meant to provide secure, tested and audited code to enable the new generation of distributed applications, protocols and organizations. OpenZeppelin is a community effort to reduce the hurdle to develop and use them.

It executes Ethereum EVM smart contract code (usually written in Solidity) on a permissioned virtual machine. Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Project information generally updated on a quarterly basis can be found on the Hyperledger Burrow Wiki.

Ethereum blockchain is a consensus-based globally executed virtual machine, also referred as Ethereum Virtual Machine (EVM) by implemented its own micro-kernel supporting a handful number of instructions, its own stack, memory and storage. This enables the radical new concept of distributed applications.
eth-private-net is a simple tool that allows you to quickly setup a three-node private Ethereum network running locally on your personal computer. The tool makes initializing, starting, and connecting nodes fast and easy. The network comes with three pre-made identities (Alice, Bob, and Lily) and a tutorial that walks you through simple actions like mining and transferring Ether, and culminates with the deployment and execution of a simple smart contract called FreeBeer. I wrote this tool because I found a lot of the Ethereum tooling opaque and difficult to understand. A lot of the information that I needed to know was scattered through the documentation, and there wasn't a single place that wrapped together the most instructive examples to build my understanding. Moreover, I wanted a tool that would allow me to repeatedly reinitialize a network from a known, clean state to help me experiment with building, deploying, and running smart contracts.
The address and ABI is all that's needed to use BTC Relay, in addition to the API documentation below.Verifies the presence of a transaction on the Bitcoin blockchain, primarily that the transaction is on Bitcoin's main chain and has at least 6 confirmations.

In Solidity it is as simple as inheriting the usingOraclize contract: this will provide you some functions, like oraclize_query, which make it trivial to leverage our technology straight away.
