The lightning network is due for a privacy boost. That’s according to Dr. Ayo Akinyele, a computer scientist who has focused his efforts on building a zcash implementation of anonymous off-chain payment architecture called BOLT. And today that work was published on Github. First conceived by zcash founders Matthew Green and Ian Miers in 2016, the code is inspired by the bitcoin scaling solution, lightning network, and seeks to unlock high levels of transaction throughput while adding payment confidentiality. “The lightning network has solved the initial issue with scalability, and now that gives us the opportunity to deal with the privacy problem. That is the strength of the BOLT design,” Akinyele told CoinDesk. Using blind signatures and zero-knowledge proofs, BOLT obscures transactions, balances and sender and receiver identities. Plus, because it’s built to function along with privacy-oriented cryptocurrency zcash, users can open a channel using shielded transactions, thereby anonymizing the
