Eh, can we please measure productivity in features and not LOC. I have the feeling that if a human implements a features compared to an AI, he needs less lines of code.

I know a lot is going on right now, but I finally made some time last weekend to simulate and compare some sponsoring solutions and a possible TXHASH stacking algorithm. Findings look interesting!

Maybe read the BIP first? It's explicitly saying that the BTC symbol stays for the 100 million base units. So it proposes 1 sat = 1 bitcoin and 1 BTC = 1 million bitcoin.
Read your shit before you start spewing opinions please.

IMO there's two parts to this. First is that CTV is relatively way more mature. Been around for a while and hasn't changed much since. So it can be adopted fast. TXHASH still has quite some room for bike-shedding.
Second is complexity. While TXHASH is way more flexible it's also an order of magnitude more complex, mostly code-wise. Needs quite some caching etc, so the code is far from trivial.
That being said, it seems that TXHASH together with CSFS enables APO in a more secure way (than CTV) and with APO, txid stability is already far less important. Which also means that indigenous fees could be a thing maybe.

Initially we thought probably not. There is a high on-chain cost associated with it, and you have to run LN infrastructure. But it might be possible if you do very infrequent rounds.
But we're currently not optimizing for that.

If you can write crypto that implements the same API, rust-secp has tooling to provide your own C lib if it meets the API.

'100 block' 'to an address'. With the "generatetoaddress" RPC.

2024-12-05 14:19:08 UTC

While y'all are checking the bitcoin price, I've got some wisdom for you developers:
Bitcoin Core's wallet seems to be crazy slow.
It takes my beefy machine 4.5 seconds to generate 100 blocks to an address in the wallet.
It takes <0.01 sec to generate to a random address.

Laat I've used it was still horrible. It would randomly start pulling in stuff shaking around the time-line every time I opened it.

I've always been sad about some missed SI opportunities. Who has to come up with "tons", f.e., while we have the perfectly good megagram? People even go as far as applying SI prefixes to the ton, using "kiloton" instead of gigagram.

Exactly. It's atomicity with an unconfirmed tx. Luckily they're optimistic and hopefully will rarely see the light of chain.

There's ark-protocol.org that I have had really good feedback on. It describes how things work in general.

2024-11-26 16:59:53 UTC

- reply

There's many facets. For one, we can do a pretty cool protocol without any covenant. Then, simple covenants like CTV or TXHASH make it a lot more powerful. But then eventually, something more powerful like MATT can probably boost it to way beyond (single tx multi-user exits fe), but that's research still and not in implementation whatsoever.

2024-11-24 01:41:54 UTC

- reply

I've actually been thinking to restructure the TXHASH BIP as an upgrade of CTV. I believe CTV is mature enough to start activation signaling tomorrow. And I'm in favor of doing that. I don't want TXHASH work to hold it back. It can perfectly be structured as a CTV upgrade without much technical debt.

I know that some people have some very liberal definition of capitalism as basically freedom, but that's not what it is. It says capital in the name for a reason. Capitalism is the doctrine in which the owner of the capital is also the right-holder of the goods produced using the capital. Nothing more nothing less.
The while free market craze is kinda misplaced because by definition, capitalism is a market disturbance.

2024-10-11 00:33:56 UTC

- reply

Capitalism is no different though. Likely even more. Socialism has a pretty loose definition, you could probably count many anarchist societies as socialist. It's kinda natural to socialize common resources. But capitalism can really only exist with a government. It's quite unnatural that capital is privately owned and workers have to yield production to supposed owners.

Ideally I'd have my reposts be posted on both sides. It also often loses track of where I am on the time-line. But in general the experience is pretty smooth!

It is, exactly this. It's dubbed "clArk" for covenant-less Ark. Obviously we want covenants, ideally a CTV of TXHASH like one that can commit the entire tx. But until then, we have clArk.

Amethyst seems to struggle keep track of where in the feed I was. I think a feed app should work on the assumption that users don't want to lose any content. So it should always go back to where it was before. Usually when I open Amethyst it's either 3 days back and I have to scroll up a lot or it's at the top and I have to scroll down.

The best plot twist would be if #Reddit turns 180 degrees and goes full donations only and becomes the best funded non-profit on the internet. I think it can easily out-fund #Wikipedia.
