On P2P payments from their FAQ: “While the payment appears to be directly between wallets, technically the operation is intermediated by the payment service provider which will typically be legally required to identify the recipient of the funds before allowing the transaction to complete.”
How about, no? How about me paying €50 to my friend for fixing my bike doesn’t need to be intermediated, KYCed, and blocked if they don’t approve of it or know who the recipient is? How about it’s none of the government’s business how I split the bill at dinner with friends? This level of surveillance is madness, especially coming from an app that touts “privacy” as a feature.
GNU Taler is a trojan horse to enable CBDC adoption. They are the friendly face to an absolutely terrifying level of government control in our lives funded by the same government that tries every year to implement chat control. Imagine your least favourite political party gaining power. Now imagine they can see and control every transaction you make. No thanks.

Except it’s got L2s, it’s got more smart contract abilties, it’s adding zk rollups, etc. It’s not like it hasn’t improved over that timespan. The stability of the core protocol and widespread consensus required to upgrade it (and the slow speed at which this occurs) is a benefit for something that is meant to be money. It’s maybe less beneficial for the world’s most cutting edge smart contract platform, for example.
They call it proof of stake, but it’s proof of ownership. It’s proving you own coins. That’s it. Edit: I think you thought I was talking about proof of authority?
I will need to look into this more so thank you for bringing this to my attention. Centralization of nodes renders much of this inconsequential imo but still worth looking into for my own knowledge.
You’re right, it was not designed to support an idea that didn’t exist when it was designed. But upgrades to improve lightning have been proposed and made it into protocol and more updates (convenants) are coming down the pipe. Lightning works, it works really well, I use it on a daily basis, the network continues to grow. It works for small transactions and large ones. It takes under a second. Cash app supports it, Coinbase added support for it this year. It’s as decentralized as base chain is, unlike many of Eth’s L2s. The only caveat to lightning for self-custody wallets is solving the “inbound liquidity” problem for onboarding new issues, which is an annoying UX thing but not actually a huge problem imo. Nonetheless, convenants will help solve this and there are other proposals (Ark and Fedimint) which solve this problem in different ways with different trade-offs. It has come a long ways in the past 5 years, I tried it when it first came out and it was a major pain to use, almost all of those pain points have been solved.
This is a good point. This WBTC is being used for DeFi etc, it’s not being used as a currency for transactions. And that’s fine, maybe that’s Eth’s place, certainly there isn’t much interest in using BTCs main chain for more complex smart contracts due to concern about bloat. There are proposals (BitVM etc) and some working implementations with “shared security” from main chain with the smart contracts being hosted in some sidechain/L2/etc. But it’s a dizzying array, we’ll see how that shakes out. I don’t know about Eth’s long-term future as a decentralized platform when centralization continues to increase and a conspiracy, hack, or government pressure on Hetzner and Amazon could impact over half the nodes on the network.
No, there is a distinction here, and it’s a very important one.
If you’re using proof of ownership then there’s no way of penalizing the owners who are validating the chain if they misbehave. That’s somewhat more like what Bitcoin uses, actually - proof of ownership of mining rigs, in a sense. If a Bitcoin miner 51% attacks the chain then after the attack is done they still have their mining rigs and can continue to attempt to attack it if they want.
With proof of stake, the resource in question - the tokens, in Ethereum’s case - are put up as a stake. Ie, they are placed under the control of the blockchain’s validation system, so if the validator tries pulling some kind of funny business their stake can be slashed. Someone who attacks Ethereum has to burn their stake in the process, which would cost them tens of billions of dollars and prevent them from attempting future attacks.
You can own millions of Ether and that’s meaningless as far as validation goes. It’s only once you put them up as a stake do you get “skin in the game.”
You were earlier touting Bitcoin’s lack of protocol upgrades as a key feature. Now it’s performing upgrades?
The problem with Bitcoin’s upgrades is that they’ve made “no hard forks” into a religious tenant, so whenever they try to do anything new they have to squish it in as a soft fork somehow built on top of the existing foundations. The existing foundations aren’t well suited to this kind of thing, though, since they were designed 15 years ago. So it makes for some very labored and inefficient design, like in the case with Lightning.
Layer 2s on something like Ethereum, which was designed from the ground up to support them and which continues to add new features making them more efficient and feature-rich, are far easier and cheaper to work with.
It’s important to call out that nodes in general are not important for validating the chain, it doesn’t matter who’s controlling them. You can run your own node and there’s nothing those other non-validating nodes can do to tamper with your view of the network, the worst they could do is stop sending you updates (which would be obvious and you could then go hunting for replacement feeds).
