Anybody knows of an LLM that has been trained in medical research databases like PubMed?

Fantastic video! Thank you for sharing: -)

Native 2-way data binding would be amazing.

Why the hard push to "save the planet"? Do they really think is necessary, is it just a wealth transfer or something entirely different?

I think it would be a solid feature to add to #Amethyst. What do you think?

Yrs, definitely. This should be an option you could turn on. I like to use very strict settings, especially this one.

For those of you who have not read Mr. Lopp's original article, here is a summary. The Cliff Notes version if you will -

Assumptions and Guarantees

- Bitcoin assumes that the majority of miners act honestly, incentivized by block rewards.

- Full nodes guarantee several facts: no monetary inflation beyond defined limits, no unauthorized spending, and no double-spending.

Thermodynamic Security

- Once a transaction is confirmed in a block, reversing it requires significant energy. An attacker needs over 50% of the network's computational power to reverse transactions.

- The cost to rewrite Bitcoin’s entire blockchain is prohibitively high (around $277 million), making such attacks impractical.

Sybil Resistance

- Bitcoin nodes are resistant to Sybil attacks, where attackers create multiple fake peers. A single honest connection allows a node to disregard false information from dishonest peers.

Consensus Properties

- Bitcoin achieves eventual consensus, exponential convergence of forks, liveness (new blocks added regularly), correctness (valid transactions only), and fairness (mining proportional to computational power).

Checkpoints and Bootstrapping

- Hard-coded checkpoints ensure a common history for new nodes, preventing Sybil attacks during initial sync.

- Bitcoin uses DNS seeds for bootstrapping, requiring trust in at least one honest seed or node.

SPV Clients vs. Full Nodes

- Simplified Payment Verification (SPV) clients download block headers, reducing resource needs but assuming valid transactions. SPV is less secure than full nodes, which verify all consensus rules.

- Running a full node offers superior security with minimal trust assumptions.

Security Considerations

- Full nodes require trusting hardware and software to some extent, though methods exist for verifying software integrity.

- Miner concentration poses risks, but incentives align against malicious behavior due to capital investment and network monitoring.

Infrastructure Options

- Alternatives like mobile wallets or SPV with custom configurations can balance security and convenience. Proxies combining third-party services with local verification offer hybrid models.

Run a Full Node Already

Running a full node provides the highest level of security for Bitcoin users, minimizing trust assumptions and ensuring financial sovereignty at minimal cost.

"The cost to rewrite Bitcoin's entire blockchain is prohibitively high (around $277 million)..."

That seens to me extremely low. When you take into account the difficulty of buying so many hardware and other factors, it's probably way higher, I assume.

I would encourage that completely! I always watch YouTube videos via a proxy, an app that retrieves the videos for me, so to watch privately, without ads and tracking. But YouTube is actively blocking this. So it's really challenging to watch YouTube without YouTube.

Rumble is a great alternative, but very few double post their videos. Although you don't know how Rumble will behave itself in the future.

Posting videos on Nostr would bring high quality video content to Nostr :-)

Fantastic. Are those numbers being updated in real-time?
