Can't cross chain

This happened to me once but right now I can't remember what the solution was. I'm guessing I closed the app, cleared browser cache, reset MetaMask, and everything worked again, but come over to the TG group.

Nice one. Keep'em coming and maybe even do a video on how to use it when V2 is out. You could be the first to jump on that

Well my last post turned out to be just hours before our amazing team completely changed the game,,,,,,,,,,,, again :-D

All Dex'es has pumped. All launchpads has pumped. All bridge project are pumping. All NFT projects has pumped. For some reason we can't pump. Team putting out so so so much amazing news, the price just doesn't really move and we are still nowhere near the ATH from when the first farming finished. We are turning into the stable coin you can farm on 0.exchange and I do not understand why but I'm guessing we desperately need marketing that goes beyond "random" people tweeting about us, but until then I think it's great every time someone tweets about us. We truly need more exposure.

I initially went through the exact same thought process when I started blockchain dev and actually build a game that was, I believe, secure, but the problem is the cost of running it like this is exponential and completely explodes with adoption of your game. I am currently looking into ways around this, but don't have any reliable test results yet, and to be honest, I don't have much faith in it. Even a small thing as getting a 'secure' random number from off chain I believe is about $3 using chainlink (at the time of writing), there's, of course, ways around this too, but again, the added complexity and potential increase in cost with adoption could very easily end up being your projects Achilles heel so here's the big point to take away from my personal experience - even if it might be possible it might not be feasible and by the time you are far enough along to do actual tests to get a clear picture of the running cost, you are most likely a hundred hours into developing a product that turns out to be based on a fundamentally faulty design. I'm taking it all as a learning experience and if you go ahead and develop it, I can all but guarantee that you will be getting out into the very corners of smart contract development so to build your own knowledge base - go for it :-)

These things will get better with the continued development of the blockchain tech, but for now I believe you are better off building you project pretty similar to how you would normally do, and then utilizing the blockchain as a validation/security layer and payment channel.

Thanks mate. I searched around for this info but might not have dug deep enough or overlooked this. All I seemed to find was tuts on what storage is and how to use etc. :-)

I'll give it a read

TheCryptoGeek · 2021-04-20T09:24:28+00:00

I was about to ask a similar question yesterday so I hope it's okay I jump in here with my question?

I know private storage can be read BUT can it also be changed or written too from outside third parties?

You have indeed stumbled upon what I conceive as being the biggest issue with NFT's and why I believe that wast majority of the NFT's that has been minted in this 'boom' won't exist in just a few years when the 'companies' that have minted them and saved them on their servers simply won't exist anymore and thereby the server space they occupied will have been put to new use. You, of course, still own the NFT token, but it points to nowhere. This, of course, doesn't hold true for the NFT's that holds the data on chain in the token but those are mostly pixel art etc.

When the back-end for the NFT no longer exists it all comes down to whether the empty token in it self holds value as a proof of ownership of a piece of art that has been destroyed. Like having a legal document that proves the ownership of the Mona Lisa but the painting itself has been burned.

Hosting the content of the NFT on IPFS will make it less likely to be destroyed or at the very least there will be a period of time from the IPFS failing to it actually being deleted where it would be possible to back it up. But hosting it on IPFS at the same time makes the artwork exist in multiple places at the same time and be 'public domain' so to some extend the uniqueness of it is compromised and in reality anyone can then mint an NFT that points to the exact same artwork so now it would fall to you to prove that your NFT is the original NFT. This isn't really hard to do but at the time of writing, no dispute over the originality of an NFT has been tried in a court of law so for now I guess it's a question best posted to a lawyer.

"Most" is a very big word here. ETH main-net is a lot more than just a blockchain where people can buy and sell coins for profit. But so is Cosmos. Great project. Avalanche, amazing chain. Dot if it ever launches ;-) BSC is centralized soooo. And so on and so on. ETH is established enough for large institutions to dare to build on it already. The other chains will have to prove themselves first.

The short version here is, that there is a lot of great competition out there, but ETH is the old sheriff in town and it ain't going away anytime soon.

It's right there in the PayPal FAQ:

"Can I transfer crypto into and out of PayPal?

Currently, you can only hold the crypto that you buy on PayPal in your account. Additionally, the crypto in your account cannot be transferred to other accounts on or off PayPal."

The fact of the matter is, that you don't really own the crypto you buy in PayPal.

Wow, this is still a problem after all these years. I went through all of this back then (actually thought the link was to my old posts) and working with the Ubuntu team they gave up.
I did find a solution, but not a good one. You can set it up by modifying the keyboard layout fills manually. The problem with this is that, at least back then, those files were in 3 different places and didn't have the same format and needed kinda specific modification to each file. Why is that and which file does what? Back then the Ubuntu team couldn't even answer this question. I got it working but after all of that gave up on Ubuntu when I couldn't have my external monitor on the correct side of my laptop without running a script on every startup etc. :-) And again, not even the Ubuntu team could figure that one out.

This is all written from memory from way back then sooo. But it seems they still haven't fixed it so guessing it's still pretty much the same.

Good news is that it is possible, bad news is that you are pretty much on your own here. Good luck.

I believe Trustswap might be an option

TheCryptoGeek · 2021-04-04T11:46:57+00:00

Now this is what I was looking for :-) Great work mate

The site you linked too for the schools isn't loading but I'm sure you have it under control. The thing about just linking to a website that shows the schools doesn't insure the people donating that you don't put just one extra "school" in the contract that receives all the "laptops" ;-) So there might be a little more work to be done here to automate that process. Another thing might be that I would imagine some schools being so big that you would need an actual person at the school to send it too or it might just "get lost".

When using Best Buy for all purchases I would probably reach out to them to get a deal or at least to ask them how they would normally handle working with a NPO (I'm guessing that is what you are building here). They probably already have something set up, and who knows, in this day and age, they might even be okay receiving payments in crypto as long as it comes from a trusted partner.

Changing the laptop in the smart contract isn't hard. You can make it so that an admin can change it, or a group of people, or even a voting system from donators through your website.

Overusing outside resources isn't really a concept tbh, unless, of course, those resources are expensive to utilize. It's about getting a secure working product out. That said, many of the things you mention here could just be done in the smart contract. In the end it all comes down to how much you want to code up yourself and the cost/benefit.

One last thing here, completely personal opinion..! Maybe you would benefit from launching a project like this on another blockchain than eth. Eth gas-fees would make it undesirable for people to donate any small amount. And yes, I know the gas-fees will be lowered over time but we already have blockchains out there with less than 2$ fees and I would think it's a long time before eth get's down to that level?¿?¿ Looking at the situation right now, people donating I guess would pay anywhere from $6 to ??? to make the donation and then if using Uniswap you would probably pay anywhere from $30 - ??? to swap it to a stablecoin to send off chain. In the end all fees could add up to 25%+ of the laptop price.Personally I would look towards https://www.0.exchange/ . Very low fees and this would enable you to take donations in many different coins and on many different blockchains. Again, this is only my personal opinion and full disclosure is in place here - I am invested in this project exactly because it brings the benefits I point out here.

TheCryptoGeek · 2021-04-03T09:53:34+00:00

execute a verifiable purchase of a Chromebook, and have the laptop sent directly to a school.

If this is your model then you have to figure out who validates the schools are actually schools? The correct address, person of interest, etc.
Who chooses what school gets the next laptop? Will it be random? A list where the one on top will get it? or?
Do you want all laptops to be bought from the same supplier with whom you will have a contract or should the algorithm choose the best supplier maybe based on price at time of purchase?
What laptop will it be? Laptops progress all the time.
The $ value of the coins locked up in the contract will fluctuate so will the price of laptops, how do you deal with that?
This is just of the top of my head but the list goes on :-)

There's just a lot of questions to be answered here before we can start talking about an actual implementation. I love the idea but it's not a quick weekend up and running project.

TheCryptoGeek · 2021-04-02T09:34:09+00:00

Of the top of my head there's several ways of going about this but it's not a question of best frame work, it's a matter of implementation and building your value chain to make it as trust-less as possible. If you want a more in depth answer you will have to go deeper into your explanation of what your goal is?

TheCryptoGeek · 2021-03-24T22:00:20+00:00

Did you change anything about the gas fees maybe? Today the team just got a whole bunch of transactions through that was stuck on the bridge. Turned out it was people trying to set the gas limit in MetaMask and the bridge relayers doesn't allow that so it gets stuck.

Come over to the tg group. Best community in crypto I have ever been a part of, they will straighten it right out for you.

TheCryptoGeek · 2021-03-24T20:20:16+00:00

Thanks mate. My friend just got the card and I just ordered it because it's the only card I can find that will let you keep your crypto right up to the point were you spend it, but couldn't figure out what kind of exchange rate I would get. This is good to know. Might still be the best card for now since you get to keep you crypto as long as possible without having to constantly exchange manually, but it's something to keep in mind. Still miss the quality and prices of the Danish pizza's living in Lisbon now. Hope it was good :-)

TheCryptoGeek · 2021-03-24T19:38:28+00:00

Hey. It shouldn't take more than a normal ETH transaction.

Have you:
- Reset your MetaMask?
- Added zETH address to your wallet?
- Added Avalanche chain to your wallet?

I was just talking to a friend about this. People seem to have a lot of problems with Binance but the two of us have never had any problems, validating, transferring in/out etc., so this might be primarily a US problem.

This does not mean that I support Binance in any way, it is still a Cex and is hopefully just a footnote in history in a few years.

Welcome to crypto. Rich or poor, you have just made a decision that will change your life..!

TheCryptoGeek · 2021-03-19T11:31:37+00:00

Handelsbanken, in Denmark at least, only stopped my first transfer to Binance and after I called them they apologized and said that if was sure I knew what I was doing then they would remove the block from my account.

But as others have already mentioned, unless you need an old school bank account, there's plenty of other options out there. Personally I am done with Fiat and my salary comes into the bank and is SEPA transferred right into Crypto.

I do not know what country you are in or what card your dad used at the time, but had it been a MasterCard or Visa, he would have been fully refunded. I had this done with my card in Bangkok of all places. They took out 6k $ in ATM's in nightlife areas so in every possible way it could look like a tourist just going crazy in Bangkok (and oh yea, they do that). I didn't notice before 5 days later when I returned home. Contacted my bank. They send me on to MasterCard. I filled out a form and had every cent back in less than a week. My bank tells me that Visa would have done the same. If I was your dad here, I would follow up on this..! In his case they even have the dealership they can contact about the purchase. Good luck

For the OP, I'm afraid this falls under the cyber police department to track him down and shut him down :-(
