Usability (speed, convenience, cost), Privacy, Decentralization, and Post-Quantum Security. Do these matter the most to us the average Joe? Where our favorite chains stand on these issues?

There's a lot of hype around blockchain and crypto, but what are the actual challenges? What do people (the average Joe like many of us) really care about? I think there are four major issues that our "favorite" blockchains need to fully resolve to make a real difference:

1. Usability

Let's be honest: for the average Joe, what matters most is probably how fast and convenient you can get things done on a blockchain, and how much it costs.

2. Privacy

This has become a major concern for blockchain adopters (everyday users, companies, banks, etc.). The rise of Zcash and other privacy chains recently speaks for itself. Blockchain is famous for being a public, transparent ledger where anyone can see the data. That’s great for preventing fraud, but we clearly don't want anyone snooping around in our damn wallets.

3. Decentralization

This basically comes down to: "who really owns or is in charge of this blockchain?" The whole point of blockchain is that there is no central boss, bank, or company in charge. It’s supposed to be run by our average Joe, or at least give him a significant level of control.

4. Post-Quantum Security

This is getting real now. "Not your keys, not your coins" is our motto. But these damn quantum computers could actually take our keys away from us. And they are coming fast and furious. You can read more about it here from Google Quantum AI. If what they found is true, there are very few chains that are really ready for this now and the near future.

I would love to hear your thoughts on where your favorite blockchains stand on these issues. Is there anything else that matters more?
