Keeping Ethereum's core devs paid costs $30M a year.
That's 0.17% of the money parked in ETH ETFs on top of their code.
The institutions earning fees on it contribute nothing.

Ethereum staking yield is quietly paying for Bitcoin's infrastructure.
@OctantApp's latest round sent its biggest grant to the Tor Project, the network behind roughly 1 in 4 $BTC nodes.
148.7 ETH to Tor all-time, all of it from yield on staked $ETH.

1/ We found a connection between @WheresBroox and the #1 Polymarket trader who made $400k betting on a ZachXBT's investigation 🧵
1/ Meet @WheresBroox (Broox Bauer), one of the multiple @AxiomExchange employees allegedly abusing the lack of access controls for internal tools to lookup sensitive user details to insider trade by tracking private wallet activity since early 2025.

I visited their office in Hong Kong and got a spox to talk.

In the end, more questions than answers. Still a mystery as to who they really are.
Something caught my eye in the latest 13F filings.
The biggest new entrant into IBIT, from a brand new entity, is something called Laurore Ltd. No website. No press. No footprint. The only public information is that the filer's name is Zhang Hui and it's HK based.
Let's double click on that for a second.
Zhang Hui is the Chinese equivalent of John Smith. It's what I like to call it a "non-anonymous anonymous" name, something hiding in plain sight buried under the statistical weight of millions to make it untraceable. The "Ltd" suffix suggests a Cayman or BVI structure, the classic offshore wrapper for accessing US markets. And the portfolio? A single holding. Nothing but IBIT. This isn't a diversified fund. It's a $436 million Bitcoin access vehicle dressed in institutional clothing.
Why would you do this?
Because Chinese investors can't hold Bitcoin.
If this is what it looks like, it might be an early sign of institutional Chinese capital moving into Bitcoin, not through crypto exchanges or gray market channels, but through a BlackRock ETF, filed with the SEC in a regulated jurisdiction hiding in the most "transparent non-transparent" place imaginable.
Funny that the name Laurore likely derives from the French l'aurore: the dawn.
Smells like capital flight to me.

Crypto has a "credibility for sale" problem, and it’s costing founders their reputations.
We analyzed 2,893 press releases over four months to see how the "wire service" machine actually works. The results were worse than we thought: 62% of crypto press releases come from projects flagged as high-risk or outright scams.
Here is how the crypto press release distribution industry is laundering reputation.

1/ Several researchers (including @Nikopolos) have attributed part of this spike to large-scale address poisoning campaigns, often executed through micro “dust” transfers
Reported losses exceed $740k across 116 victims
🧵 here's how it works
🚨 What happens when Ethereum can push ~30% more throughput and keep fee pressure muted?
Last 14d vs 90d baseline:
▫️ avg Daily TXs +35.5% (2.385M), peak 2.884M
▫️ avg Daily TPS +35.5% (27.61), peak 33.38 TPS
▫️ avg Active addresses +33.2% (1.135M), peak 1.454M
These spikes appear to be a genuine step-up.

In new research, @Nikopolos calls out rampant address poisoning as the main driver behind the recent ATH activity spike on Etheruem mainnet.
He argues that Ethereum needs "to fix fundamental problems first" before focusing on scaling and lowering fees.

🪙 Ethereum Hits Record 2.5M Daily Transactions — But Is It Spam Attack? 📊⚠️
Researcher Andrey Sergeenkov connects the all-time high tx volume directly to massive "address poisoning" spam.
Thanks to ultra-cheap gas post-Fusaka upgrade, scammers are flooding the network with tiny "dust" transfers — tricking users into sending funds to fake addresses that look like legit ones in wallet history.
Result? Over $740,000 already stolen via these sophisticated scams.
Network congestion from real usage... or security nightmare? Protect your addresses, double-check EVERY send! 👇

INSIGHT: Ethereum hit a record 2.9M daily transactions, but data suggests the growth is linked to address-poisoning spam, not real user demand.
The activity picked up after the Fusaka upgrade which cut average transaction fees by about 6×, making dust attacks cheaper to run.
Andrey Sergeenkov retweeted
A researcher warns a recent Ethereum upgrade is being exploited for address-poisoning attacks that trick users into sending funds to fake addresses.
