\begin{tabular}{llll}

Tier & Privacy Level & Technology & Use Case \\
|
|
\midrule
|
|
Tier 0 & Public & Standard EVM & Transparent DeFi \\
|
|
Tier 1 & Shielded & zk-SNARKs & Private transfers \\
|
|
Tier 2 & Confidential & FHE & Encrypted DeFi \\
|
|
Tier 3 & Trusted & TEE (SGX/SEV) & Regulated finance \\
