The Intel vulnerability

Hello from North Carolina.
Will the Intel problem affect the Cardano protocol?

Not the protocol itself, but if you have your wallet (Daedalus) installed on a PC or Mac with an Intel or AMD processor you are at risk.

You could use a hardware wallet like Ledger Nano or Trezor to protect your coins.

There are patches out.

I suspect the vulnerabilities have been around a while and run their course hence the release of patches.

Thats my cynical side though.
