The Privacy Crisis
The Web2 Trust Problem
Traditional cloud services (Google Drive, Dropbox, iCloud) operate on a trust-based model. Users surrender custody of their data to centralized entities that:
Possess master keys capable of decrypting all user data
Are subject to government subpoenas and warrantless surveillance
Monetize user data through behavioral profiling and targeted advertising
Historical precedent: The 2013 Snowden revelations exposed systematic backdoor access to cloud infrastructure by intelligence agencies. The 2021 Pegasus spyware scandal demonstrated that even end-to-end encrypted messaging can be compromised at the device level.
The Blockchain Transparency Paradox
Public blockchains offer censorship resistance but sacrifice privacy. On Ethereum, Solana, or Bitcoin:
Every transaction is permanently recorded and globally visible
Address clustering techniques can de-anonymize users
MEV (Maximal Extractable Value) bots exploit transaction visibility for profit
Regulatory compliance becomes impossible without revealing sensitive data
Limitations of Existing Privacy Solutions
Privacy Coins (Monero, Zcash):
High computational overhead (Zcash shielded transactions: ~60s generation time)
Limited programmability and DeFi composability
Regulatory stigma leading to exchange delistings
Mixers & Tumblers:
Centralized coordinators create single points of failure
Vulnerable to timing analysis and Sybil attacks
Often flagged as "high-risk" by compliance tools
Trusted Execution Environments (TEEs):
Reliance on hardware manufacturers (Intel SGX, ARM TrustZone)
History of side-channel vulnerabilities (Spectre, Meltdown)
Closed-source attestation mechanisms
