[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

You can send a message instantly.
You can call your family instantly.
Why does sending money still cost so much?
This should not cost this much.

Millions of people work, trade, and build communities every day.
The economy depends on their contribution,
yet systems still do not reach everyone equally.
The world is connected.
Access should be too.

What if payments moved through identity… not fragmented banking rails?

[MetaMUI | The Next Crypto Era @MMUI_Official]

Bitcoin started the last era.
That doesn't guarantee it leads the next one.
Every technological shift creates new leaders.
Crypto won't be different.

Ethereum is powerful.
But complexity creates risk.
Wallets.
Validators.
Bridges.
More layers = more attack surfaces.

While QBFT and PoA are understandable choices for deterministic settlement, Byzantine Fault Tolerance was originally designed for adversarial environments with potentially anonymous or untrusted validators. In a wholesale CBDC system composed of regulated, identity-known institutions, applying a BFT-style replicated consensus model may introduce unnecessary coordination overhead and latency costs for what is fundamentally a trusted low-latency liquidity settlement network.

WBTC might break before Bitcoin.
Most people are looking at the wrong risk.
More layers = more attack surfaces.
