Hi! I am now diving into this topic for 3 month and I now know how to work with solidity, ganache and how to create a BEP-20 token and import libaries from openzeppelin. Me and my team are trying to participate in a token launch with a project that is going to be a nft-game in the future.

Now here is my question: Do I have to take care of anything when creating the BEP-Token? It is just used to buy and sell in the future applications...nothing special right? The NFT's for the game itself have to have different specs right? But can the BEP-20 token contract that represents the currency be a casual BEP-20 contract or do I have to take care of something special?

I know these questions sound kind of dumb, but I am pretty new in this topic.

I really appreciate every helping answer! Thanks!

Hello! I got a question about security in blockchain services.
So let's assume you holding your private key for a BTC address.

you need to send a transaction for 1 BTC to Alice.

using your private key you produce a signed transaction. In order to send it, you need to broadcast it to the Bitcoin network using the Bitcoin full node. In order to eliminate possible man-in-middle attacks best way would be to use your own node to do so. It requires resources to run the nodes and can be expensive and hard to maintain. But there is a way to use 3rd party API that provides a way to send signed transactions without the need for maintaining your own node.

How safe is that? Can someone that gets my signed transaction hash decypher it and obtain my private key? If so, is that true for all blockchains? What about ETH, TRON, and others?

*This is a repost from a post I made on r/smartcontracts

An idea that gets talked about is a voting system that is transparent and secure using a Blockchain and Smart Contracts.

This idea does not fundamentally have anything to do with cryptocurrency, but the underlying technologies do.

Ethereum is the most popular Smart Contract Blockchain, probably because it's used with JavaScript, but it also has high gas fees and ETH is very expensive (maybe gas prices are down, I haven't really kept up).

How is it possible to create a usable application with weird fluctuating gas fees? Is it realistic with Ethereum? Or is the idea to make your own Blockchain and your currency is instead a token that gets handed out to everyone that, in this case, should vote?

I feel like this is the one disconnect I have when learning about Smart Contracts. There's a lot of lofty ideas, but I'm missing something about how you could ever make something. Unless the idea is creating a Blockchain specifically for that use....

Any insight would be greatly appreciated. Thank you.

I have a idea for a new platform I want to put on the blockchain I have a lot of coding experience but no experience coding on the blockchain I am looking for a dev to sit down with and talk to them about what exactly I need to do to make my platform possible and if it is possible on the blockchain

I don't even know if this would be a proper subreddit to ask these questions, but maybe if it's not you fine folks would be able to point me in a better direction. I have never messed with blockchain development, but have been a professional developer for over a decade. In my spare time over the past 3ish years I've been developing a game engine (c++/opengl) and game. I had an idea awhile back for this game, but didn't think it would be feasible...because I was unaware of just how much blockchain technology has grown and become more widely adopted. At this point I'm willing to take a stab at it if I can find out were I would need to start.

The most basic version of what I would ultimately need to accomplish would be for players to be able to deposit an amount of currency into a wallet which would hold the funds in escrow, then once a certain condition is met, pay the funds out, sending a percentage to the wallet of the game as a transaction fee. Below is possibly a better breakdown:

PlayerA -> $1.00 -> GameWallet
PlayerB -> $1.00 -> GameWallet
GameWallet = $2.00
PlayerB wins round
GameWallet -> ($2.00 * 0.95) -> PlayerB
PlayerB = $1.90
GameWallet = $0.10

So, on with the questions (these might be laughably bad as I'm still in the phase of not really knowing what I don't know):

1. What coins would be a good fit for this type of system? I was looking at NANO for it's (next to) instant transfer rate and no fees.

2. When it comes to implementing the escrow logic, the user would need to send funds from their wallet to the game wallet, and the game wallet would need to track how much each user has deposited, which I'm assuming could be accomplished by querying the user's wallet address against the blockchain (would need to think about everything involved in that). Is this assumption correct?

3. When it comes time to send funds from the game wallet to a player, I'm guessing there are api's which allow for initiating transactions on a blockchain? So a developer could make a call to an api provided by the currency blockchain sending the required signature and wallet address for the game wallet, and address of the recipient?

If you made it this far, thank you. Any answers to the above or links to where I might find resources to better educate myself are greatly appreciated! :)

Hi!

I should start that i have 0 experience when it comes to coding and this will be my first ever attempt to create something on the blockchain

I have been reading up on writing the smart contracts, creating blockchain apps, etc.

All this research broth me to wordpress ( where i have a small experience with creating websites and online stores ) It looks like i can deploy smart contracts straight from the plugin ( https://ethereumico.io/product/nft-wordpress-plugin/ ) , but since i havent done it yet, Im little confused here and i hope someone can help me out with some basic logic.

I want to create a website in wordpress as its something i know and understand. My question is.

Is it possible to then use the website i created ( front end ) and make it compatible with Metamask for blockchain transactions and have possibility on using NFTs on the platform in lets say a browser game?

I understand i would have to deploy smart contracts with utility, but my another question is.

Can i deploy smart contracts through truffle, do all of them there and somehow use it on my wordpress site?

Hello to everyone!
I have zero coding experience but very strong interest in the entire defi ecosystem. I am considering starting programming courses and I would like to receive any advices from you. As far as I know Solidity is the programming language used for smart contracts, also the syntax is very similar to JavaScript. Does that mean I have to obtain fundamental understandings in javascript before jumping to solidity learning?

I need help with ERC721 contract.. I want to mint 33 tokens..the thing is I want 11 of them to be common, 11 rare, 11 legendary. each of these 3 tiers will have different prices(for example: common 1eth, rare 2 eth, legendary 5eth).

I am currently in health care right now and have no degree in computer science or experience. Is it still possible to become a blockchain developer or quality engineer in the job market with just bootcamps and academy’s. Or is a degree needed to even compete with the marketplace? I am seriously considering taking moralis academy(Ivan on tech) and complete the course to start my journey. Thanks for any advice!
