Prague EIP-1153: Transient Storage (TSTORE & TLOAD)
Explore the revolutionary EIP-1153 transient storage opcodes introduced in Prague. Learn how TSTORE eliminates 95% of reentrancy guard gas overhead by utilizing an ephemeral per-transaction storage buffer.

🧠LIFO Stack Model
Stack is 1024 words deep. Maximum 16 words can be directly addressed via SWAP and DUP instructions.
📐Quadratic Expansion
Active memory is byte-addressed. Every expansion incurs linear plus quadratic fee to penalize unbounded state growth.
⚡Prague Ephemeral Store
TSTORE and TLOAD operate on key-value pairs that vanish at transaction boundaries with zero disk commit overhead.
