Today we reached a massive milestone at @zama_fhe : bootstrapping in less than 1 milliseconds.
Bootstrapping in FHE allows “cleaning” the noise in encrypted data, and is responsible for the vast majority of the computation time. Thus, the faster bootstrapping gets, the more confidential transactions per second the Zama Protocol can process.
We achieved this after years of research on efficiently using GPUs for FHE. The results are MINDBLOWING:
Boostrapping latency:
- 2021: 53 ms
- today: 0.9 ms
- speedup: 56x
When applied to integers arithmetics, the results are even more insane:
64 bit encrypted addition latency:
- 2022: 2,000 ms
- today: 8.7 ms
- speedup: 230x
64 bit encrypted multiplication latency:
- 2022: 13,000 ms
- today: 32 ms
- speedup: 400x
To understand what this means in practice, lets look at confidential stablecoin transfers:
- 2022: 0.1 tps
- today: 230 tps
FHE is now FASTER than Ethereum and most L2s! And it’s only a matter of months before we can reach 1000 tps.
Next steps: build an FHE ASIC to reach 100k tps by 2029. Enough to cover Visa, Mastercard and SWIFT volume combined.
