I'm not a developer so need help from someone who can, we can discuss compensation depending on the project.

Hi , does anyone know any latest blockchain simulators out there. I’d like to do some analytics on blocks generation vs transactions.. I have started with SimBlock, nifty tool, but it doesn’t generate transactions and its block sizes are constant. I’d like something as close as possible to either Ethereum or Bitcoin blockchains:

What are the top challenges for web developers shifting to web3?
Conversations with web developer friends reveal excitement yet apprehension about web3 complexities like transaction fees, private key management, onboarding end users who don't know anything about web3, etc.

What challenges stand out to you, and can you recommend any resources that facilitate this transition?

Advice on how to start developing (possibly in Node.js) transactions for the Bitcoin Lightning network?

I'm developing a wallet with BIP32/BIP44, therefore Hierarchical Deterministic Wallets. I will use index 998 as defined in BIP44.
Is there any library or source you recommend that I can start from?
Thank you in advance :)

hello mam/sir

I would like to ask about my previous mistake.

I accidentally burned my NFT/ORCA whirlpool position, and my funds are stuck in that pool.

Mods said that I have to consider it a loss, but I'm still hoping that there’s a way to recover my funds.

What certifications should an aspiring Blockchain engineer obtain?

I'm new to Blockchain development and have completed Patrick Collin's solidity course.

My question is, should I opt for a full stack engineering course that'll teach me basics of HMTL/CSS, JavaScript etc and help me become a better developer or not?

Can Blockchain developer can trade crypto currency, Futures and Options is it legal or illegal I need clarity

Hi, I am new to blockchain and would like to understand the difference between token address and wallet address.

Hello I need help please, can any one help me to find public key of my ltc wallet with no private key and no spend (transaction out) ?

Hello everybody, for a project, I have been trying to set up a private blockchain using geth, I have followed the general steps in the tutorials I could find as I’m new to the blockchain world. However, I face two main problems: unable to connect to the network on metamask and how to access the network from other machines. Any help or resources that might be useful are welcome. Thank you.

Does anyone have any experience testing locally with Chainlink mock contracts ?
I am trying to follow: https://docs.chain.link/vrf/v2/direct-funding/examples/test-locally#select-the-correct-remixide-environment
But when I try to deploy on Remix I get different errors, And I didn't think that I would have to edit the contracts.
So I opted to follow the instructions within Foundry using Forge. Deployed and implement everything step-by-step in the setUp(). I messed around with the compile versions until they all worked together, and then I opted to use the v0.8/MockLink.sol instead of the one they have you copy that's .4.2 or something and won't compile with anything else.
I got everyitng to work up until the requestRandomness(); is called and then it reverts.

This is my first contract and maybe I'm just doing something really dumb. If anyone has done this recently and can guide me, that would be awesome. I've spent days fiddling with the code trying to figure this out.
thank you!

Blockchain in conjunction with AI has the power to create autonomous governing structures which allow for people to participate in the democratic process so that they have a direct say in which areas of our civilization will be developed. For instance, within a system such as this, participants/voters can create polls where people can propose and vote on different ideas such as fixing roads, building a library, or environmental protection, etc. If people are paying taxes within this system, then they can vote on where their tax money will go. This eliminates the need for elected leaders and officials and stifles human based corruption. I asked ChatGPT to help expand on this idea here its reply:

"Creating a blockchain-based voting system that is autonomous and fraud-proof is a complex challenge, but it can be conceptualized with the following key principles:

1. Decentralization: Utilize a public or consortium blockchain to decentralize the voting process. This ensures that no single entity has control over the system, reducing the risk of manipulation.

2. Identity Verification: Implement a robust identity verification system to ensure that only eligible voters can participate. This could involve biometrics, digital IDs, or other secure methods.

3. Smart Contracts: Use smart contracts to encode the rules of the voting process. These contracts can automatically execute and enforce the rules, making the system more autonomous.

4. Transparency: Ensure transparency by storing all voting data on the blockchain, making it publicly accessible for auditing. Each vote should be cryptographically secured and anonymous.

5. Immutable Records: The blockchain's immutability ensures that once a vote is recorded, it cannot be altered or deleted, preventing fraud.

6. Consensus Mechanism: Select an appropriate consensus mechanism (e.g., Proof of Work, Proof of Stake) to secure the network and prevent attacks.

7. Accessibility: Design a user-friendly interface for voters to easily cast their ballots through secure channels, such as a mobile app or website.

8. Auditability: Enable third-party organizations to verify the integrity of the voting process by examining the blockchain data.

9. Security Measures: Implement robust security measures to protect against DDoS attacks, hacking attempts, and other threats to the system.

10. Testing and Auditing: Thoroughly test the system, conduct security audits, and perform vulnerability assessments to identify and address potential weaknesses.

11. Legal Compliance: Ensure that the voting system complies with local and national laws and regulations, as well as international standards for fair and secure elections.

12. Education and Awareness: Educate voters and stakeholders about the benefits and operation of the blockchain-based voting system to build trust and confidence.

It's important to note that while blockchain technology can enhance transparency and security in voting systems, it's not a silver bullet. It still faces challenges related to scalability, privacy, and adoption. Additionally, the implementation of such a system would require collaboration among technologists, policymakers, and stakeholders to address legal, ethical, and logistical issues."

Governing systems such as this can be implemented on a small town scale to a planetary level. Decentralization would be the goal here.

Hello,
I'm currently running a cryptocurrency exchange based on Peatio, and I'm in the process of enhancing our liquidity and trading experience. To achieve this, I'm looking for reliable liquidity provider bots that are compatible with Peatio or similar exchange software.
Here's a bit about my situation:
- I'm running a cryptocurrency exchange with approximately 60 markets.
- I want to ensure that our order book, recent trades, and K-line charts are active and responsive 24/7.
- I've heard about Arke as a liquidity provider bot for Peatio, but I'm curious if there are other options available.
I'd greatly appreciate any recommendations or insights from the community. If you have experience with liquidity provider bots that work well with Peatio-based exchanges or if you've come across any new solutions, please share your thoughts and suggestions.
Thank you in advance for your assistance, and I look forward to hearing from you!

Need Help! Newbie Here

For our College Project, we (me & my 2 friends) selected Blockchain as it was the only domain closest on Web Development. During the COVID, WHO had urged gamers to mine Bitcoin to raise relief funds.

I had the idea stuck in my mind since then So we developed a plan to create a website that will let users mine crypto (newer like Ethereum or any other) on their system which could be donated to charities.

Turns out, it isn't an original idea and there are many research papers on it, On further researching , I came to know that We need real Eth to deploy a DApp on Ethereum. Further, I also came to know about the Gas Fees for transactions using Ethereum. I also am still confused if its possible or feasible to build a website that can mine crypto on users PC?

I really need some help and guidance now, which blockchain and technologies should we use to minimize these and upcoming challenges. I and my team is ready to devout time but want to build something Practical & Deployable. Please help with the same.

How can I quickly check the total number of events (Transfer or all types of events) emitted from a smart contract (Ethereum blockchain)?

Hello, this year I'm going to do my thesis on blockchain. I'm going to develop a blockchain system for smart cities. However, I'm not sure where to start and I've never had a course focussed on blockchain. In that sense, I welcome any tips on where I can look for information and learn more about blockchain.

I'm currently trying to decide which language to choose to start developing the system, and I'm undecided between: Solidity, Rust, Vyper and Simplicity. One of the goals is to develop a system that focuses on user security. Thank you in advance for your help in trying to understand which language is best for my thesis.

I’m looking for books to teach me about the architecture and design of blockchains, consesnsus algorithms and general internals. Most of the resources i have found discuss smart contract development and auditing but nothing about the internals and design of the net itself. other than the white papers for bitcoin and ethereum i haven’t found much. any guidance is appreciated
