I do lower case ‘r’ research on bitcoin l2s, sidechains, and BTC-based derivative assets
does nostr have ai slop too
hi nostr friends
been in the void for months and am currently bullish on statechains and ark. I’m still need-sniped by rollups from a research perspective
Podcast on zkCoins // Shielded CSV is finally out.
It’s an introduction to a protocol that could be the future of scalable, private payments on bitcoin.
Available here.
Stoked to be heading to @PUBKEY this evening to talk about L2s, bridges, and more.
If you’re in NYC, come through. As always, if you manage to recognize me, I’ll buy you a beer :)
cbBTC is completely centralized and coinbase admits that in their docs.
However, base’s “bring the world onchain” marketing campaigns will handwave away the fact that the entire system users is permissioned and can rug them at any minute.
Users don’t change defaults. People won’t “go onchain”, learn how to use “crypto”, and then promote themselves to a more secure system. They’ll just stay on base. Coinbase will direct them there.
There’s nothing wrong with this from a business perspective. There’s a market demand. Coinbase meets it.
But if this is the endgame (we’ll see) for “Bitcoin DeFi”, we have little to no reason to build any of these applications on blockchains. You don’t need a blockchain for completely centralized application modules. It’s just a technique to provide some illusion of decentralization imo
If you see me at the bar, I’ll buy your next beer
This place is class


I don’t really see how any sidechain or rollup is a “bitcoin layer” outside of social consensus deciding that it is
I’m going to @PUBKEY Tuesday night. If you’re in NYC and want to grab a drink, let me know
not gonna lie
fact checking is a terrible business model
@Alex B. - what are some questions you want me to ask the rollup teams next week on a spaces?
The sentiment on Twitter is that this is the most exciting time for bitcoin “L2s” whilst tbtc on arbitrum has a better trust assumption than anything on the market
I’m really annoyed that I’m not in Riga.
Not a huge fan of “we did it first” but this might be the first podcast on BitVM2?
I chatted with Alexei Zamyatin, one of the paper’s co-authors, about BitVM2, BitVM Bridge, and how it can support better sidechains. Check it out!
Feedback also welcome. New-ish to hosting podcast-style discussions.
Interesting few days.
- We wrote a review on the ICP subnet that manages its Bitcoin-synthetic
- Most people were like, yeah, fair enough
- Some people accused of being paid to write a hit piece on ICP
- Then they all ganged up on us
- I was like "wtf?"
- Then the ICP devs were like "yeah, everything they wrote is true"
Everyone is still mad lmao
we are currently getting yelled at by the latter group here
View quoted note →
Maxis yell at us for writing about shitcoins. Shitcoiners yell at us for writing about their shitcoin.
Comfy
We did a review on ICP. They call themselves a Bitcoin L2 in some marketing stuff.
Tl;dr is that they have a blockchain of 28 nodes managing their BTC multisig and sidechain. Some other depedencies, but this is the main trust assumption.
It takes 10 of the 28 nodes to collude and steal user funds.
