The Tor Project, Inc., a 501(c)(3) nonprofit organization advancing human rights and freedoms by creating and deploying free and open source anonymity and privacy technologies, is seeking an experienced systems programmer to work on the Applications team. In 2008, an anonymous author using the pseudonym Satoshi Nakamoto, published a white paper outlining a public transaction ledger for a decentralized peer-to-peer payment system entitled Bitcoin: A Peer-to-Peer Electronic Cash System, which is regarded as the 'birth' of blockchain.This job is no longer active - check out our currently active jobs Since then, the use of blockchain has evolved beyond its original implementation as a cryptocurrency.

It has gained momentum in recent years, being adopted by some of the largest organizations in the world, including IBM, Amazon, PayPal, Mastercard, and many others. However, due to the fast moving innovation and adoption of blockchain, and the unfamiliar concepts compared to more understood and traditional technologies, its use is still hindered by speculation, confusion, uncertainty, and risk. In SEC554: Blockchain and Smart Contract Security, you will become familiar with essential topics of blockchain and smart contract technology, including its history, design principles, architecture, business use cases, regulatory environment, and technical specifications. The course takes a detailed look at the mechanics behind the cryptography and the transactions that make blockchain work.

It provides exercises that will teach you how to use tools to deploy, audit, scan, and exploit blockchain and smart contract assets. Hands-on labs and exercises will enable you to deploy, audit, scan, and exploit various blockchain implementations, such as Bitcoin, Ethereum, Solana, Cosmos, Near and others, as well as smart contract languages like Solidity and Rust, along with protocols, such as NFTs, DeFi, and Web3. There have already been widespread security breaches, fraud, and hacks on blockchain platforms, resulting in billions of dollars in losses. These issues, along with growing scrutiny by government agencies to find malicious users abusing the technology, is tarnishing blockchain's reputation.
