I believe this is a *very* important part of the ecosystem, god knows it has done wonders for ethereum. Is this at a point where you would like people to test it? I can certainly do that, I have a gap in a couple of weeks. Just let me know when you are ready.
I sincerely appreciate the kind words, H! No doubt Infura has played a massive role in making Ethereum a more attractive place for prospective and existing Ethereum developers which is why we're so appreciative of them for paving the way.We're going to be launching our beta really, really soon (as in tomorrow) and I'll be sure to post here first in order to let you and everyone else know!
Imho you should stay as close as possible and do things like the established networks (ethereum) do it, unless you have a very compelling reason to deviate... there are already problems because Daedalus wallet decided to “do it different”. Just my opinion.
all tx's are included immediately, but invalid tx's become invalid after time, whereas in bitcoin and ethereum for example, invalid tx's are never included and are discarded by nodes from the mempool before being included in a proposed block
I started to test using Cardano and I found IELE and testnet. I also saw under Remix Ether is used. Is Cardano processing Ether txns? Also is there a gas cost in Ether. Is Cardano then a sidechain of Ethereum?
I assume there is some kind of wallet which deploys the contract into the simulator and hence we need the keys for that wallet. I am unusure how Cardano uses wallets and if there is something similar to Metamask for Ethereum. I usually would use Metamask and remix. The udemy course draws a parallel to remix and ethereum; and Plutus/Playground.
I cannot find any testnet for Cardano - similar Ropsten for Ethereum. I saw Plutus Playground but what are we meant to do to test a web UI? Plutus Playground is just a means of testing a smart contract but we need something which integrates into a system for solving a business level problem. s there any testnet which has something like etherscan and basic options to deploy, test, check code?
I am a little nonplussed by all this. How are we meant to test a web UI app which uses Cardano? That is what I am trying to do. Hence a user enters data into a web form and the form then saves into Cardano - that is a fairly standard Ethereum type of function. I am not sure how we can do this using Cardano.
All those web dApps on Ethereum are possible because of metamask. Metamask’s integration via web3 hooks means you can tie a DOM event, like a button click, to opening metamask to make a transaction from the users wallet. This does not exist (yet) in the Cardano world.
Similar with mobile phone apps (or any stand alone app really), if you want the app to be able to show balance, receive and send - it needs a wallet built in. On Ethereum you add a library and make calls to Infura (hosted node service)... could you do this in Cardano now, yes, but I think you'd have to cross-compile Rust libraries to iOS and Android, you have to reverse engineer their cardano-cli command line tool to work out what library calls to do when, then talk to your (or hosted) node... doesn't sound fun does it.
Thanks that helps. Actually when using Ethereum (due to the dislike of Metamask in the market) I have used an API service and then users run tokenized credits and the API keys work out their balances. This is a hybrid answer but with zero-knowledge and biometrics all coming into the market now, we can id the user without any keys and hence relate a user id app to the actual balance without a wallet on the phone or browser. I will attempt to implement an API service to update my own Cardano which you seem to be saying should work.
But there is a hackathon on 21 June sponsored by Cardano. That was my interest. So this has me confused. Why sponsor a hackathon when no smart contracts exist? I have a used a lot of blockchains (NEO, Corda, Hyperledger, Ethereum, EOS, and sidechains (RSK, Skale)) and I cannot see the point of Cardano getting involved as a sponsor when smart contracts are not implemented outside of Plutus Playground and KEVM. Am I missing something?
Hey all. I have been looking at various models of smart contract execution and was wondering if Cardano would be able to do something like the DAO in Ethereum? Where a dynamic set of members vote on proposals and if enough members vote for it, the recipient receives the money. I don't quite grasp what the limitations of Plutus's model are (with validator/data scripts). It seems like it would be hard to maintain dynamic state like this, but the paper gives a crowdfunding example which kind of requires dynamic state to maintain information about backers.
Yes I believe IOHK still plans on KEVM which will enable ethereum solidity apps to run on cardano. So if you wanted to start, you can go that route. There's also the haskell route which might be harder, but will have your code running more predictably and works seamlessly with the smart contracts that they've built.
I don’t know how Cardano will do things, but on Ethereum you can get the state at the end of blocks. Eg you can call balanceOf(A) for block number 123. I’m unaware of an easy way of getting the state in the middle of a block.
Anyone here a game dev?I've been recommending the developer behind Etherlinker for Unreal Engine to consider Cardano in the future. An Etherlink style plugin would be amazing for game dev's interesting in using blockchain tech. In the forum post he was talking about funding being an issue for his current plugin so maybe that's something Cardano could help him with.Here's an example of Etherlinker and how it enables game devs to integrate Ethereum standards.

So, I have read quite a few introductory posts and videos of what Cardano is about.I understand that it is a smart contract protocol that aims to solve what Ethereum can't in terms of scalability, interoperability and sustainability.I particularly like the treasury bit. How the community votes on improvement proposals so that funds raised via ICO using Cardano is more transaparent and responsible.My question is, so can I build a cryptocurrency and launch a token sale using Cardano now?Coz I can't find anybody who has.

The problem with Algorand is that they have assumption that millions of people will run the nodes so subset will be secure , however this cannot be practical as size of blockchain increases over time , for example ethereum has > 1 tera byte size of blockchain, so not many nodes can be run which requires so much storage capacity. So it is important to have dedicated stake pool which earns commission for delegates tokens by providing infrastructure. The assumption of million and may be even billions nodes in Algorand will remain only theoretical. And Algorand has instant finality which Cardano do not have so it has to implement measures to avoid 51% attack like Finality reversion , Invalid chain finalization , liveness denial, censorship. There are various solution to achieve this and I don't know what cardano is exactly implementing as I have not seen their documents recently but the technic to solve Invalid chain finalization is fraud proof submission by minority node. Similarly Liveness denial(validator stops finalizing blocks) can be solved by gradually reducing non participating node. I went through Algorand docs and I am not convinced it is practical even though it has support of 15 universities and many PhD and Turing award winner. May be I am wrong but I am not convinced how millions of people will participate in block formation provided nodes requires validation and in turn they have to store big blockchain in tera byte in future. May be they will use some compression technique or only the latest blocks or pruning the unnecessary data to reduce the storage size or may be sharding. But yet the data size will grow overtime so a dedicated services like stake pool is required. 😔. Any way we will see .
I think so. Never used it, but they have something like Infura on Ethereum. On Infura, you sign the transaction locally, then submit. I can’t remember what these guys call their version, but I am sure it exists.
You know how Ethereum is frequently making a soft-fork, and the nodes resolve this by following longest chain. Am I correct in thinking that won’t happen in Cardano because block producer for a slot is decided in advance? @OldCryptoGeek
So, hello everyone :) I'm developing some stuff and want to integrate Cardano. With Bitcoin, it's pretty simple (just wrap electrum, lol), Ethereum have Infura, which is also pretty useful.I want to find something like that for Cardano. What's better to try right now? Performance is not the issue.At the end it'll be something like that:seed, address, err := cryptocurrency.Cardano.GenWallet()...balance, err := cryptocurrency.Cardano.Balance(seed)...tx, err := cryptocurrency.Cardano.Send(seed, dest, amount)(I have the same API for bitcoin already)
Okay, you're sure with the ability to launch dpos within the network. It seems to me that it's not possible on ethereum for example. For the duration of the release I hope coguen will be delivered before decembre 2020. That's a timeline I can hold.
Hello everyone, I was hoping to get some suggestions and advice. Just getting a solid handle on developing dapps. I have built a couple on the Rinkeby Ethereum test net with a Reactjs frontend and I want to shift and start building on Cardano. Reading Plutus hand book and taking Udemy Plutus course now. Can you give me suggestions on what I should focus on after learning Plutus? Thanks a bunch.
