A QR code can hide a destination. Preview the URL, check the full domain, and pause before connecting a wallet or signing a request. A familiar logo is not proof that a link is trustworthy. #OnlineSafety #WalletSecurity

This week is a YUGE one 🎙️ On Episode 7 of The Post-Quantum Experience, we’re joined by Antti Ropponen, Executive Partner at @IBM Consulting. IBM is building quantum computers and helping the world defend against them at the same time. Antti breaks down what a real quantum-safe migration looks like and why signatures are the hard part. Must watch 👇

Before relying on a security result, look for its scope, timestamp and limitations. What was checked? What was not checked? A clear explanation matters as much as the result. #CyberSecurity #Web3

Someone offering wallet support? Use the official support channel. Never send a seed phrase or private key in a DM, form or screen share. Keep recovery information private. #WalletSecurity #OnlineSafety

Before signing a wallet request, ask: Which site sent it? What permission does it request? Why is it needed? If you cannot explain the request, stop and investigate. #WalletSecurity #Web3Safety

A screenshot can leave out the context. Before trusting a security claim, check the original source, its date and what was actually tested. Look beyond the image. Read the evidence. #Web3Security #OnlineSafety

Post-quantum standards are here. NIST finalized ML-KEM, ML-DSA and SLH-DSA in 2024. Adopting them requires migration—not just a new label. Learn from the source: csrc.nist.gov/Projects/post-… #PostQuantum #CyberSecurity

Disconnecting a website does not revoke its token approvals. Review which contracts still have spending access and revoke permissions you no longer need. Know what stays authorized. #WalletSecurity #Web3Safety

“Claim now” is a prompt to pause, not a reason to rush. A countdown does not prove an offer is legitimate. Verify the source and understand the wallet request before signing. Take your time. Keep control. #WalletSecurity #Web3Safety

A familiar logo does not prove a link is genuine. Before connecting your wallet, check the exact domain, open a trusted bookmark and review every signature request. Pause. Verify. Then decide. #Web3Security #WalletSafety

Help us make Quantum Shield clearer. Try the public beta and tell us which results need better explanations. Keep private keys and personal details out of feedback. quantumsshield.com t.me/QuntumsShield #Web3Security

For public wallet checks, use a public address. Never paste a seed phrase or private key into a scanner, support chat or feedback form. quantumsshield.com/tools #WalletSecurity #Web3Security

A result needs context. Read the selected network and source block alongside a wallet check. Account state can change after the check. Explore the public tools: quantumsshield.com/tools #Onchain #Web3Security

Checking a wallet? Select the network first. Quantum Shield supports Ethereum, Base, BNB Chain, Arbitrum and Polygon for public account checks. One network does not tell the whole story. quantumsshield.com/tools #Web3 #Onchain

Token names can be copied. Start with the contract address. Quantum Shield Token Check reads name, symbol, decimals and reported supply on supported networks. Metadata is not a safety verdict. quantumsshield.com/tools?product=… #Web3Security #Onchain

✍️ What a post-quantum signature actually is: Classical signatures are the maths behind every wallet. You hold a private key. It produces a public key. You sign with the private key, and anyone can check the signature against the public key without ever seeing the private one. That one-way trick has held for forty years. It works because turning the public key back into the private key is impossible for a normal computer. A quantum computer running Shor's algorithm reverses it. The public key becomes the private key, and the signature becomes forgeable. Enter post-quantum signatures. Same job, different maths. ML-DSA, the NIST standard, rests on lattice problems: finding one hidden point in a grid of hundreds of dimensions. No known quantum shortcut. The signature is larger, around 4,600 bytes against 64, and a quantum computer can't forge it. → On NaoX, transactions can be signed with ML-DSA-87, FIPS 204 at Security Level 5, the strongest parameter set the standard defines → Verified natively by the chain in around 38.5 microseconds, roughly 26,000 per second per core → Same wallet, same tools, no change for the developer A signature built for the world before Q Day comes.

⚙️ Introducing Proof of Security, the NaoX consensus mechanism Fine, the transactions are post-quantum. Who validates them? Validators are the machines whose signatures decide a chain's history. If their keys are classical, a quantum computer can forge them. That's locking the vault and leaving the guards' credentials on a sticky note. Proof of Security is built the other way round. A validator cannot join without a post-quantum key. The registry accepts exactly 2,592 bytes, one ML-DSA-87 public key, and refuses everything else. In the chain's own code, since genesis. → The gate: only 2,592-byte ML-DSA-87 keys → The stake: validators bond collateral, misbehaviour is slashable → The committees: validators attest to blocks together → The honest line: finality aggregation is classical BLS today, as across all proof of stake Commitments in blog posts can be edited. Commitments in genesis cannot. Old keys don't age out of this consensus. They never get in 🚪 GM!

Press send on a crypto transaction, and it's protected by maths a quantum computer will break. On a post-quantum chain like NaoX, every step that follows is different, and you'd never notice. Here's how a post-quantum blockchain works ⬇️
