Discussion 7 smart contracts per 20 seconds

2 Upvotes

A reddit user u/NabyK8ta commented in post about Cardano, and he made an argument

Quoting

“Ada is slower than a glacier and more expensive than every one of its competitors.

Here’s how slow it is.

One block every 20 seconds. Each block is 72kb. One smart contract is 10kb. So that’s 7 smart contracts per 20 seconds. That is unusable.

They wanted to increase blocksize to improve this so they did tests on a testnet. What they found was that they could increase it from 64kb to 72kb. That’s the limit.

Smart contracts cost 1 Ada so just under $2 at the moment. Every other smart contract platform is cheaper including Ethereum if you use one of the plethora of scaling solutions like Arbitrum which you can bridge to from a CEX like binance without fees.”

I feel this requires an answers from Plutus and Cardano blockchain experts.

Is this claim true? If not how ?

Discussion Major vulnerability? Too many UTXOs...can't submit transactions...ADA + native assets are locked in wallet. Please tell me I'm wrong!

1 Upvotes

TLDR: My wallet has too many UTXOs associated with it and I cannot submit transactions to the blockchain anymore - the ADA and native assets are locked in the wallet, unable to be sent. In theory, couldn't people mint 1000s of junk NFTs and flood people's wallets with unwanted UTXOs - essentially locking their ADA and other assets in place?

FULL STORY: I've been handling the minting for a CNFT project - we minted about 3k tokens at launch and then sales died down. Our policy locks in May so we decided to create a holding wallet and mint the remaining 7k just to be safe.

1: First, I created a holding wallet with 1 single payment address through the CLI - I run a full node on AWS. I didn't even think about creating more than 1 address at the time. You can view the wallet here https://cardanoscan.io/address/0104e59e0c56f2f3629bbc42d66c64983c45011578e807f8d06b11a250c402b98bb1020ac3c8a529e1e65b1dd0d6c1afba265d613b12b54813

2: I began minting tokens and sending them to the holding wallet. 331 in total were minted before discovering the issue.

3: I discovered the issue when a customer purchased one of the tokens that had been stored in the holding wallet. When I tried to send them the token - the following error was thrown...

Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraAlonzo (ApplyTxError [UtxowFailure (WrappedShelleyEraFailure (UtxoFailure (MaxTxSizeUTxO 17214 16384)))])

Issue: Basically I can't submit transactions - the associated 331 UTXOs render any transactions too large to be submitted.

Vulnerability: While this is a bummer for our project and customers, it made me think - couldn't nefarious parties target any wallet by simply minting and sending 300-400 junk NFTs to the address? The wallet would run into the same problem.

Any help would be greatly appreciated. I'm not an advanced user by any means so I'm hoping I'm just missing something here. Thank you.

Job Offer I have an idea for a Cardano based company. I have an MVP built. Looking for some developers.

1 Upvotes

As the title says, I am looking to build a very simple, yet useable, service for the people of Cardano. This is purely a retail based service company that solves one small problem. This idea was once in the real world, then moved to the internet, and now I would like to take it to the blockchain. My goals with this post is to look for a front end and back end developer to help turn the MVP into a really clean and simple user experience. We might also need an NFT artist/graphic designer. My current product works, and does everything as it should, but there are ways to make the service 10x better than it currently is. For example, part of the company is NFT based and I am leveraging a service. In order to cut costs and personalize the experience to our product, I could use help deploying our own technology to mint NFT without a service middle man. There are more scenarios like this where technical expertise helps this product both make more revenue through cost reduction but also streamline the user experience. A front end developer could work with the backend developer to help provide an input field on our website where metadata could be filled out an added to a freshly minted NFT (basically like ada.handle).

I do not have the technical knowledge to complete these actions. I am offering equity ownership in this company based on deliverables. If you are interested to learn more, I would be happy to share, but I will have some questions to build trust first. I am keeping my idea close to the chest and am looking for a solid team that would be interested in completing this product and possibly tackling other projects as I have many. We will not need any capital investment to finish this product as long as all team members, including myself, can work for equity. I run a Cardano based Youtube channel and am active in the Twitter/Reddit communities, so I am confident in my ability to raise awareness for the project. Comment below if you would like to talk more. I am on discord or here or Twitter so we can talk in any of those.

Job Offer Metaverse project looking for Developer

0 Upvotes

We have a metaverse and landpieces as nfts, we want to sell bulks of the coordinates, which should be still random. For example:

Someone buys 9 nfts, there should be a chance that its a 3x3 pieces on random coordinates which are available to mint

Also that if someone buys 8, that it could be 2 times 2x2 or 1 2x2 and 2 1x1

A bit clearer:

Map has 6 different places where 3x3 bulks are defined.

Person 1 buys 3x3, he receives randomly 1 3x3 from that 6 possibilities. How is it possible that these 9 nfts are the correct coordinates of that one place with the 3x3

We also want to be able to have royalties, airdrops and after mint a possibility for website integration of a kind

For this we are looking for a Developer that has experience with smart contracts and can help us build something unique.

We would pay you from 80$ an hour to 10% of the revenue of the Mint.

If you're interested please DM me

Job Offer Looking for a Developer for a Fun Project

1 Upvotes

Hello, r/CardanoDevelopers! I currently have an idea for a type of game that I would really like to develop an application for. I have essentially no programming knowledge, so I am looking for somebody who would like to help. The game will be very similar to a Super Bowl block pool. In the spirit of crypto, I'd really like to run it on the Cardano network and make a native token for it, especially with smart contracts not far away.

If anybody is interested, message me. We can absolutely discuss compensation - I understand your time and effort is not free.

Thanks, Mike

Discussion Remember the old send 5 people $1 dollar through the mail idea?

2 Upvotes

I remember when I was younger I got an email where you would send $1 to 5 people on a list then remove the 5th person and add your name and address 5o the list. The whole point, I believe, was to have a bunch of people sending dollars to each person thus creating a chain of pools/money that would hit each person at different times.

My folks at the time said it was illegal so needless to say I never did it.

Is something like this possible via blockchain via smart contract?

User buys in with 5 token and the contract automatically does the rest as far as the list.

Simple concept but it would need to be tweaked and set up properly so it would be worth doing.

I like the idea of PoolTogether on eth and it's got me thinking.

Discussion Cardano-Wallet server won't restore my wallet through mnemonic_sentence

1 Upvotes

When I try to restore a users wallet through cardano-wallet (testnet) I get this payload using the [POST] /wallets
endpoint

{   "code": "wallet_already_exists",   "message": "This operation would yield a wallet with the following id: 8209f39a872faa51a63c0f7bb8d748067cf7b2b0 However, I already know of a wallet with this id." } 

The following payload I send is the name,mnemonic_sentence & passphrase with the same arguments I gave it while creating the wallet. I even went as far as to change the name & passphrase but I still get the same wallet_already_exists error.

{   "name": "Recovery Wallet",   "mnemonic_sentence": [     <15 KEYS>   ],   "passphrase": "wallet_pass_01" } 

I read that Cardano-Wallet should lookup a wallet and return its funds when a mnemonic_sentence derives a wallet that already exists. As you can see this isn't working for me & I don't see how I can force a recovery.
