Coda Protocol: Using zk-SNARKs For A Constant-Size Blockchain

The Main Event (LIMITED TO 50 ENGINEERS):

SF Cryptocurrency Devs is an engineers-only developer meetup for blockchain engineers seeking to learn about the innovation surrounding new and emerging applications of cryptography to digital currencies.

We would like to introduce SF Cryptocurrency and Bitcoin engineers to the Coda Protocol!

Izaak Meckler will give an approachable overview of Coda: the first cryptocurrency with a constant-sized blockchain. Instead of persisting the entire blockchain, Coda uses recursive composition of zk-SNARKs to compress the blockchain into a tiny proof and sends around that proof instead. That means that no matter how big the blockchain gets, or how many transactions are performed, the cost to verify transactions and data remains constant and inexpensive — around 20kbs and 10ms to verify an account's balance.
