> will be dated more recently than the other How does the receiver of such a transfer know that the transfer is final? There's no way for them to know that an "earlier" transfer of same item won't show up days later.

The key is the "any arbitrary program". With zk-snarks, I can, theoretically, run some complex analysis of some data -- imagine something that requires millions of compute hours -- and provide a receiver (a) the answer, and (b) a

No it has to be a pure function with no reference to outside systems, and the function has to be in the complexity class np.

zksnarks are one of the most wonderful results in computer science and mathematics. On first learning of them, I had the common reaction of "I can't believe this is even possible to do". The way that I came to intuitively und

I think it’s a little different because people do regularly maintain bridges without replacing them and rerouting all traffic. But I get your drift. What a crazy thought to have these completely autonomous programs moving billions in value.

Thank you for the information. Yes, I was talking about the proxy pattern. My mental model was that this was the classic approach. I did not know that popular major projects were using immutable smart contracts. This seems crazy to me, but

by aboodman 5y ago
This makes sense to me and I think can be considered decentralized. How common are completely immutable contracts though? It seems like for any contract that holds significant value it would be insane to make it immutable, particularly when

Your comment doesn't address the point of the article. The author isn't talking about Ethereum itself, which they acknowledge up front can comfortably be considered decentralized. The point is smart contracts. They are code, and t

Alright, there is some naming collision then. "offline-first" (terrible name, but here we are) generally refers to a classic web application that wants to be able to run offline either for network resiliency reasons or for perform

For a SaaS style (aka client-server) application, the right way to think of client-side storage is as a persistent cache, for a few reasons: * it can be deleted at anytime (by browser, or even by user!) * you generally want the server to be

You should take a look at my project, Replicache: replicache.dev. While it is true that you have to duplicate the mutations in the basic setup, you do not have to share the querying/reading code as it lives primarily on the client. A

Ah, when I brotli compress it locally, it's 188 (which is where I remembered 100 from) but I guess it uses different settings than the auto-brotli in Vercel.

Cool, I need to look into this more. I think for many customers the authoritative server is an advantage. It's useful in SaaS apps for the server to be able to override the clients, for all kinds of reasons -- antiabuse, authorization,

Replicache is not hosted - it's client-side only. You bring your own backend.

I’m not sure if you are understanding that when Replicache rebases operations locally it actually re-executes code which can have arbitrary effects. This design yields a lot of flexibility to preserve intent: the function can look at curren

OK but, it usually matters. If the events represent changes to some object, those changes almost always have to be handled in order if you are to arrive at the same end state as the source. edit: Also, idempotent is not the right term her

It the system is moving fast this is still somewhat complicated to implement robustly because by the time the "catchup" request to t0 returns, more time has passed and more events have happened, so you still can't resume cons

Did you check the website? The value prop is incredibly clear: they give you a Postgres database you can query with SQL rather than having to either (a) learn and code to a custom API or (b) setup your own sync system to get that Postgres d

I noticed the same thing when I stopped working ft. I was surprisingly bad at predicting my own interests and what would make me feel happy day to day. It was almost as if I didn’t know myself, and in retrospect I suppose that was true. Aft

Real time, if accurate, allows you to establish relative ordering without coordination. With logical clocks, you can only establish partial order.

This preview version of Next.js Live doesn't do anything special for text editing. It just locks the document while one user is editing. We are excited to work with Vercel to add true collaborative text editing on top of Replicache soo

The keystrokes edit the local in-memory state and are synchronized in batches to the server and other collaborators. Learn more here: https://replicache.dev/

Yeah, Replicache is in beta right now, and we haven't quite finished the detailed server-side documentation. Apologies . However, there is a walkthrough of implementing the server side starting here: https://doc.replicache.d
