I continue my learning with Binance, progressing slowly with BNB Chain Developer. I am in the BNB Greenfield module, which as far as I understand is decentralized storage on steroids. If it is more than just that, please write your clarification in the comments.

I liked the previous modules because they had practical exercises, creating an ERC20 token and an ERC721 NFT and deploying them on the testnet. I enjoyed that experience. However, without practical use cases for Greenfield, I find it hard to understand its existence and even more its benefit to the ecosystem.

On the other hand, I started the Blockchain for Business Sustainability course. I find it very interesting, although I struggle to follow along since my strength is not in economics.

Hello everyone! Here I am again commenting on my journey in learning Software Developer in Blockchain. As a good beginner, I have already completed the CryptoZombies course. Since last year, I have been taking the Binance BNB Chain Developer course. I have enough confidence to develop something. But therein lies my problem, finding that something.

One idea that comes to my mind is to implement a voting system in my country, or at least achieve a proof of concept. The contract that handles the voting is relatively simple, the problem is access control (that only verified citizens can vote) and delivering a Soulbound NFT as evidence of participation.

For the voters, a basic CRUD comes to mind, with off-chain validation. But being able to implement a relatively efficient storage solution is the issue. Or at least it is for me. A mapping?

Then comes the second problem, interaction between contracts. There I don't know whether to inherit or provide an interface. Adding to that is where to store the data.

Frustration is my worst enemy and I don't want to leave this project abandoned.

Finally, the training of citizens. Perhaps starting as a sectional project. Maybe I am overthinking it and getting ahead of myself.

Let me know in the comments if you have any ideas.

What's happening with the market?!

That's the question everyone is asking. One person opens their mouth, signs a document promising an economic paradise, only for prices to plummet minutes later.

But those of us who live by trends and technical analysis know that this is the normal cycle of cryptocurrency prices. Sometimes it's subtle, sometimes it's more aggressive.

If you don't want to enter the cryptocurrency market and die trying, check out the tools that Binance provides: Market Overview is the most basic tool, you can get a broad view of what's happening in the financial market and make informed decisions. A social tool is reading the articles on Binance Square, as it provides real-time data from other users, some beginners and others more experienced. Binance offers more tools for more experienced users, but that's another article.

Analyzing how to start creating a smart contract, there is the easy way, the simple one, and the complex one.

The easy one is to use Remix IDE, but the problem is that it is an online environment. Not very friendly if the internet connection is unreliable. This leads me to analyze "offline" options.

The simple one, Hardhat. It is the framework backed by the Ethereum community and the most recommended right now. Personally, I like it because it doesn't require many things, it installs as a project dependency, initializes, and you have what you need available. But I feel that its parts are not completely connected.

This leads me to the complex one, using the Truffle suite, which consists of a framework that is installed on the system. Accompanying it is Ganache, a blockchain simulation that runs locally. Truffle was the first framework for the development of smart contracts.

What I like about Truffle is that it has commands to create the parts or everything necessary to start writing a smart contract, testing it, and/or deploying it. Perhaps my familiarity with tools like Artisan makes me see this tool as easier to use than Hardhat.

I will be honest with you: I am not a trader, not even close. I believe I have lost a total of about $500 in the last year trying to understand the indicators and making trades.

I am a developer who mainly works with Javascript and PHP, using the Angular and Laravel frameworks. That is what I do know how to do. And I am going to delve into the world of developing Smart Contracts with Solidity. Yes, I know, one more to the group.

What surprises me is that there hasn't been much information or tutorials in the last 2 to 3 years. The platforms that have something updated use their own platform to skip certain steps that, as an independent developer (and in bankruptcy), are very important!

So I am going to create a 30-day challenge to progressively understand the strange concepts of Solidity and in the end be able to carry out a project where the community can collaborate with me and I can give back to those who have lost with those "airdrops" that have only given out scraps.

A lot of cryptocurrency information is transmitted by communities on Telegram. Especially about airdrops.

One caught my attention, from the MINT network I think. But when I went step by step and read everything, I realized that one in particular is a wallet drainer, because when I signed up (a process that usually has no cost or is very low), it appeared to me that it was taking ALL the funds from my wallet.

Be careful! Check every step you take. This time of low prices is ideal for scammers to take advantage of people who want to enter the world of cryptocurrencies.

I said it in December and, although the price between January and early February was high, the price of $BTC , $ETH , $SOL and the other altcoins followed the annual trend, down in the month of March. Not as far as I expected, at 72000, but it was close, around 78000. In any case, the correction is taking place, so the price should recover and hold until the end of the year.

See you in the next "bull run".

Memecoins are a way to make some quick money... It all depends on the investment volume and the time you invest. Obviously, not all memecoins will be listed on CEXs, many barely get listed on several DEXs. This seemingly is a quality that contributes to their price and profit. We have several examples like $HMSTR , $CATI , among others...

The main delivery method for these coins has been airdrops via Telegram bots. The users' sentiment is: "we are already tired." They take a lot of time, change the delivery rules at the last moment, millions of users participating... they already understand the idea.

The time for Telegram bots has ended (no one stays for the second season). The time for testnets has returned.

Testnets are nothing new. The compatible wallet is registered, a certain amount of test tokens is taken from a faucet, and transactions are made with other users. When the testnet ends its trial period and becomes mainnet, users receive a certain amount of tokens that can later be converted to USDT/USDC (when the respective contract is integrated into the network).

I'm not a professional analyst. In fact, I've lost a lot of money due to different situations related to cryptocurrencies (following bad advice from pseudo-analysts, binary options, various scams), but I'm good at recognizing patterns...

So I hope $BTC has a fall (as is its normal cycle) and in March it reaches 72K and by October-November it reaches 122K (at least).

What do you think?
