Summary

This chapter covered blockchain privacy – a subject of profound importance. We covered what privacy is, its different facets, and how can we solve the privacy problem on blockchain. We also saw major technologies, such as ZKPs and particularly SNARKs, which are the most advanced and used form of ZKPs to solve privacy problems on the blockchain.

Moreover, we explored how Zokrates can be used to create zero-knowledge programs to complement the theoretical concepts, covered earlier in this chapter. Regarding privacy, we have many solutions, including but not limited to Zcash, Manta, Aleo, ZKOPRU, Aztec, and Espresso. To solve scalability, some key solutions are zkSync, Scroll, and Polygon Hermez.

In the next chapter we will introduce security, which is another challenge that blockchain technology faces.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
