For every important person in your life there will be a day when you will see them for the last time.

Just remember that the next time you'll see them.

Just use Cloudflare and AWS and you will not have any issues they said.

Technology leads, politicians follow.

It's hilarious that the concept Homo economicus models humans as consistently rational, when it's actually quite the opposite.

What I like about the Zcash community:

Nobody asked me if want to join a Telegram group yet —the standard in most of crypto.

Only Signal groups.

They get it.

Zcash is getting repriced in real time.

Being a Zcasher is easy compared to being a gold bug in the 1980s.

Was there ever a U.S. government shutdown where the debt ceiling wasn't raised?

"No, we are not going to eat the cookies!"

*dancing around*

"Lets eat the cookies!"

Long: BTC, ZEC, XAU

Short: USD, EUR, CHF

NSM in Zcash

- problem: future security budget (tx fees not enough?)

- constraint: 21M cap

- proposal: Network Sustainability Mechanism

- ZIP 233: establish voluntary burn mechanism

- ZIP 234: smooths the issuance curve (adds burned coins)

- ZIP 235: burn 60% of transaction fees

Crosslink proposal

- adds assured finality to Zcash by introducing PoS finalizers

- hybrid PoS/PoW ("defence in depth")

- rooster of 100 stake weighted finalizers (they take fee)

- yield for stakers (40% stakers, 40% miners, 20% dev fund)

- staking from Orchard pool

- 21M cap

ZSAs (Zcash Shielded Assets)

- Orchard extension enabling the creation, transfer, and burn of custom assets (like ERC-20)

- also allows for NFTs

- assets can be wrapped assets (with bridging)

- same anonymity as shielded ZEC transactions, sharing the pool

- no freeze function

Levels of wealth:

- debt

- no debt

- debt

If it’s OK to filter transactions with “too much” OP_RETURN data, wouldn’t it be also OK by the same logic to filter CoinJoin transactions with too many inputs and outputs?

After all, what useful purpose do they serve?

They are not transferring value.

Your threat model should include sophisticated technical attackers.

But don't forget to include the unsophisticated non-technical religious mob.

Less ego leads to more success.

It allows you to learn and adapt.

The real cost is not making a mistake, it's defending it.

“What if a plumber came and fixed your sink and you paid him $40? He went into the bank and he goes, ‘I’d like to cash this check. Mr. McAfee wrote it to me and I’d like my $40, and, while you’re there, would you please tell me what his balance is, and, from now on, forever, would you please inform me every time he has an incoming wire or deposit, and every check that he writes, and to whom?’”

“That’s what bitcoin is,” McAfee said. “Would you be happy if your bank did that?” He added, “Please, you know you wouldn’t. We know, if anybody has any sense, and if you understand human nature, then privacy coins will be the winner.”

Privacy coins, also sometimes referred to as anonymous coins, are cryptocurrencies such as monero (XMR) and zcash (ZEC) that tout capabilities to hide transactions and other activities.

(from a John McAfee interview with Forbes in 2019)

Some cryptocurrency tribes build bridges and trade with other tribes.

Others go to war and isolate themselves.

Which strategy is more likely to succeed in the long run?

You cannot be both a Bitcoin Maxi and Monero Maxi at the same time.

If you join a religion, you have to decide.

That feeling when you only have two administrative tasks to do and then you can code all day, but you have a hard time getting yourself to do them.

#Zcash

AI agents will need embeddable crypto wallets to pay other AI agents and services.

Assuming that AI agents are rational actors, do you think they would prefer all of their economic activity to be transparent or private?

Imagine a world where ONE payment will give you the total revenue of a business, their customers, their suppliers, how much they pay their employees, and what their cashflow and runway is.

Welcome to stable coins.

International commerce simply doesn't work without privacy.

Bitcoin protects you from monetary debasement.

What protects you from taxation and confiscation?

You cannot convince people to buy something because you want them to, you have to focus on their problems.

People buy Bitcoin because it solves their "melting ice cube" problem and makes their number go up.

What problem do privacy coins solve and how to we have to improve the UX in order to get more users?
