Crypto's Privacy Problem...
The discussion between
@randhindi (
@zama ) and Charles Guillemet (
@Ledger ) explains why public blockchains lack true privacy and how new cryptographic tools aim to fix it.
-->Blockchains Sacrifice Privacy for Verifiability
Public chains like Bitcoin/Ethereum expose all transactions so anyone can verify them. This “privacy paradox” is like the early web before HTTPS.
--> TEEs Aren’t a Real Solution
Trusted hardware (Intel SGX, etc.) is fragile, repeatedly hacked, and relies on single manufacturers. Ledger avoids this approach and sticks to securing keys only.
--> Fully Homomorphic Encryption (FHE) Is the Breakthrough
FHE allows smart contracts and computations on encrypted data.
@zama ’s improvements now make FHE practical, giving blockchains privacy without losing public verifiability.
-->Institutions Will Drive Privacy Adoption
Banks and funds cannot operate on a fully transparent ledger. The future is “programmable privacy,” where users stay private but regulators get controlled access when needed.
-->Privacy Becomes Standard Infrastructure
@randhindi predicts that FHE will become as common as SSL powering most blockchain transactions in the future. Privacy isn’t a trend but a core layer that blockchains currently lack.
