Blockstream was founded in 2014 by Dr. Adam Back and a group of fellow cryptographers and engineers passionate about Bitcoin and its potential to change the future of finance. Focusing on building fundamental Bitcoin infrastructure, Blockstream quickly grew into one of the leading technology power houses of the industry
Through our sidechain technology (the Liquid Network), wallets (Blockstream Green, Blockstream Jade, AQUA), mining colocation (Blockstream Mining), satellite network (Blockstream Satellite), and protocol contributions (Bitcoin research, c-lightning), we are proud to be making global peer-to-peer finance a reality
The research team supports Blockstreamâs efforts and the wider Bitcoin ecosystem. The main focus is on signature schemes and scripting languages for the Bitcoin protocol, sidechains and the Lightning Network. Furthermore, Blockstream Research drives key open source projects in the Bitcoin space.
What Youâll Be Doing (Responsibilities):
- Contribute to open source cryptography libraries such as {rust-,}secp256k1{,-zkp} (implement new schemes, review, QA)
- Help with designing, developing and breaking new cryptographic schemes
- Devise and critically evaluate specifications of cryptographic systems, e.g., in the multi-, threshold- and aggregate-signature space.
What We Look For In You (Required Qualifications):
- Experience implementing cryptography
- Care about secure and misuse-resistant designs
Nice To Haves (Preferred Qualifications):
- Knowledge of Rust or C or willingness to learn C89
- Previous academic work on digital signatures, discrete logarithm based cryptography, post-quantum cryptography, zero-knowledge proofs, or other areas of cryptography
- Master's degree or PhD in Computer Science or a related field
- Familiarity with Bitcoin and Layer 2âs at a protocol level
- Familiarity with contributing to open source projects
What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
