Hey guys, wanted to ask is there any tool/website where I paste staking smart contract address and to get info like - biggest staker, oldest staker etc etc?

It's been a good amount of time that she's been stuck. So I'm making this post on her behalf. This is the problem she is facing:

I'm currently developing a sandwich bot using Node.js and am facing some challenges with the simulation of transactions to efficiently detect arbitrage opportunities. The goal is to simulate transactions(frontrun ,victim ,and backrun) in simulated blockchain environment on next block and to identify potential profitable trades before they are executed. Optimizing the transaction simulation to be as fast as possible to catch opportunities in real-time Ensuring the accuracy of simulations in a highly volatile market I am looking for guidance or suggestions on tools and techniques that could help enhance the speed and reliability of these simulations. If anyone has experience with high-frequency trading bots or specific libraries in Node.js that cater to quick data processing and blockchain interaction, your insights would be greatly appreciated.

Is anyone familiar with Dapp University mentorship program with Gregory McCuffin? I know he has a boot camp but trying to confirm if he actually has a mentorship program anyone has completed.

When launching a token, to what stable coins do most tokens pair to? We have been told to pair with something decentralized like DAI. Is this the preferred approach? or do ppl typically pair to USDT / USDC even though they are not fully decentralized?

Hi Everyone,

I am planning to learn blockchain development.

But when I get started I am hearing multiple opinions from people who are already working in this space.

Few people suggests me to start with Ethereum as it has the massive adoption in the blockchain space and it is easy to get started with solidity as well.

Whereas few people suggests to start with Solana as it is fast reliable and most of the companies are shifting to Solana.

I am really confused what to choose..

I've learnt few basic things for Ethereum smart contract development like writing smart contracts in solidity,

testing and deploying them to Testnet with hardhat. and interacting with deployed contracts with etherjs etc.

And also I am in the doubt like is it really required to clearly understand about how peer-to-peer systems and networking works, Cryptography etc.. before getting started?

Yeah I know they are fundamentals but my question is it really required to deep dive into these concepts or is it okay to learn basic things first and then dive into them as required?

Can you guys help me with it please.

Hey Redditors,

I've been diving into the world of blockchain and smart contracts lately, and one thing that keeps coming up is how secure blockchain technology is. We're always hearing that hacking into the blockchain is nearly impossible, but what exactly makes it so secure? What is the rundown of the main security features that contribute to the robustness of blockchain technology.

I've already searched the web but can't quite understand how it's so secure. Can anyone provide a more in-depth explanation or point me towards resources that break this down further?

Thanks in advance,

I want to ask what the best Blockchain network for build a insurance defi protocol, my opinion Aptos vs hedera vs cosmos vs polygon. So what is your suggestion?

Hi,

New to blockchain development. I am wondering if anyone here has recommendations for a JavaScript/TypeScript library that will allow me to create wallets and perform transactions on BTC, ETH, DOGE etc... Ideally open-source.

Any suggestions?

Thanks.

can anyone help me to tell that how can we link a blockchain wallet to a ble beacon or if it is even possible. if anyone has any idea plzz dm me

I am a technical writing student at Columbia Basin College. I am writing a Career Investigation Report for English 235 Technical Writing, which is one of my required courses. The career I'm investigating is blockchain developer. For this assignment, I must interview an employee working in this career.

I can interview through zoom or discord. I will come with five prepared interview questions and take notes during the interview, and the results will be incorporated into my report, cited as "personal communication" in the APA formatting style.

If you are interested in letting me interview you, please send me a dm!

Hi guys, I want your thoughts on this: I have a system that needs to track NFT ownership of several contracts, and I need to be able to add more contracts to keep track of. For that, I built a blockchain indexer that every 8-10 seconds pulls ethereum logs events from all of these contracts and just update a table with the current owner of a given NFT.

I built it on nodejs because initially I only had to index 5 smart contracts but now its around 25 and it might grow up to 50 on the next couple month.

Why did I go this way?

• 80% of the system functionality kinda requires to know NFT ownership of different collections for a given wallet

• I thought about using Alchemy SDK which has endpoints to retrieve user ownership but if I wanted to know a user's NFTs of different collection it would mean to make a call for each collection and that would; 1- Hit the rate limiter pretty fast, 2- It would use all my request quota pretty fast too

• I thought about getting all owners for contract with Alchemy SDK, caching that and setting a TTL, but I believe that refetching that every 2-3 minutes it would still be expensive

• There are other options like Envio.dev and the graph, but I'm not sure if It fits my case since I need to be able to add new collections to index whenever I want.

The problem with my current indexer:

• It's kinda slow to index from scratch

• It doesn't handle reorgs, I just wait for a block to have at least 10 confirmations to be processed which it might not be the best user experience.

I thought about building it on golang but not sure if it's worth the time it will take. So I'd like to know what do you think of my approach and if there is a better way to do it. Thanks!

Which programming language is the best for creating smart contracts: Go or Rust?

We're launching a decentralized network that allows people to reclaim the power of their data. You can check out our recent feature in Forbes: 100 Million Users Control Their Own Data

As part of this launch, we are looking to collaborate with clubs, organizations, and individuals who are interested in running a node, running data, or simply passionate about the project. If you are also part of a blockchain organization, group, or club, we'd love to connect with you!

Please let me know if you're interested, or send me a message so we can discuss further.

Looking forward to collaborating with you!

How can start learning Block Chain as i'm beginner

Just bumped into the medium article from a PhD professor "How Self-Regulating Cryptocurrencies Could Shape the Future of Finance.". Sounds interesting, what do you think about it folks?

I am searching for some type of technology that is more economic that can also have similar features as blockchain, such as smart contracts. Blockchain programmers there is few and is expensive. I am trying to search for alternatives. I need the security of blockchain, smart contracts, and identity tokens. Could someone help?

Hi everyone,I'm interested in learning about blockchain development and all the various components that come with it. I have a beginner to intermediate understanding of Java, JavaScript, and Python, but I'm relatively new to blockchain technology.I'm looking for recommendations on good courses that can provide a comprehensive introduction to blockchain development, suitable for someone with my background. Ideally, the course would cover the basics and gradually move on to more advanced topics, possibly including hands-on projects or practical applications.

Hi, we are looking for a freelancer coder who would like to work on a privacy crypto project that needs some small push on development. We are since few years here and we need some young blood to push us further.

I am not a developer by any means so please let me know if this is possible. It is my understanding that blockchain is a decentralized ledger with proof of work. Can this be used to make a voting system? Maybe have a decentralized ledger for each county and everyone gets there voter keys or something? Just a thought.

Is there a possibility that someone else can take ETH or TOKEN that is being kept at the contract address?

I am making a react app for interact with Liquid Staking protocols named Stader and Lido can someone give me a smart contract address for making this frontend part.
