"4/11) In 1976 Whitfield Diffie proposed public key cryptography. Many experts thought it was crazy. Keys were supposed to be secret But Diffies idea was beyond wild: use a public key to encrypt and a private key to decrypt"

"5/11) He teamed up with Martin Hellman and Ralph Merkle to find a system that could do this. They published Diffie-Hellman key exchange the paint-mixing trick that lets strangers agree on a secret over an open line"

"6/11) A year later Rivest Shamir and Adleman turned it into RSA. Suddenly the internet could be born: HTTPS SSH Bitcoin WhatsApp all built on never meeting yet still trusting"

"7/11) Thing is experts came up with an advanced computer the Quantum Computer that works with qubits. Unlike regular bits (0 or 1) qubits can be X X and everything in between at once (superposition). With Shors algorithm a big enough quantum machine can factor huge numbers in hours. This is the exact math RSA and ECDSA (Bitcoins signature) depend on"

"8/11) "Harvest now decrypt later" A spy today can store your encrypted traffic or your Bitcoin public key. In 1525 years when quantum computers scale to millions of stable qubits theyll turn the lock"

"9/11) If todays crypto doesnt update its math the damage is catastrophic: - Every HTTPS session recorded since 2010 readable. - Every reused Bitcoin address private key exposed coins stolen. - Every old WhatsApp backup plaintext"

"10/11) But the fix exists: Post-Quantum Cryptography (PQC). NIST standardized Kyber (key exchange) and Dilithium (signatures) in 20222024. Theyre bigger slower but quantum-proof. Bitcoin is already in talks"
