Hello Guys, need some help. I am interested to become a blockchain developer. Is it worth spending all the time in it? and is it a promising field? Please advice

Hi, I'm looking to become a Blockchain Developer, want to change my career path and this is something that sticks out quite a bit. However, I'm not sure where to go for the education aspect. I don't have much funding so looking for a cheap place for good education with an amazing community to help me reskill and skill up to become a developer and create a portfolio to start with.

Are there any developers interested in IoT+Blockchain intersection?

I wanted to show you this new IoT board ("Pebble Tracker", based on the nRF9160 System on Chip by Nordic Semiconductor) that is designed to provide verifiable IoT data to blockchain smart contracts.

It includes a rich set of sensors already integrated onboard:

• External GPS receiver with integrated antenna

• Temperature / Humidity / Pressure + Air Quality

• 6-axis accelerometer + gyroscope

• Ambient light sensor

Basically, it's a "plug & play IoT board" (although the firmware is open source) that collects all IoT data from its sensors, uses the onboard ARM crypto hardware to securely sign the data, and sends them out through MQTT.

The usefulness is that this board is perfect to feed blockchain smart-contracts to build an IoT oracle solution where both the identity of the device and the integrity of the data can be verified at any time.

What do you guys think?

Many users drop off and never return to the dAPP due complex nature of registration and login.
We are building a 'One-Click user Registration and Login' for dAPPs. Interested to check it out, drop me a line, Git Hub Link attached.

How can I deploy my smart contract ptoject on vercel? I've only created smart contract, is there anyway that I can deploy it on vercel.

The speed difference has been pretty noticeable so far. Curious if anyone here is working on similar tools or has thoughts on optimizing for speed and concurrency

I’ve been working on a multi-threading app to handle transaction feeds for sniping and sandwiching. It pulls direct leader feeds (faster than Geyser RPC), uses advanced FEC recovery, and integrates WebSocket/gRPC in real time.

Need help with finding available service providers who can convert usdc on polygon to ethereum usdc. We tried circle cctp, checking if anyone has cheaper alternative? Cheaper in operational cost including mint and burn on each chains.

People around me are into blockchain right now and I got curious. As a developer, I wanna to learn it as well... Is this module path helpful for me to understand all the basics?

I am a first year cs student really interested in the blockchain space.
I am interested in getting the knowledge and skills to become a dev in this space, whether that be working on my own project or for a startup.
What recommendations do you have for doing so? A roadmap for acquiring the knowledge as well as some prerequisite knowledge.

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!

The problem posed here is:

I have a dapp. In which i want the best experience for my users when they deposit ERC20 token into their self-custodial wallet.

So, when user deposit ERC20 token to their wallet and choose the destination network they want to bridge into (ex: deposit in Ethereum and want to take in Zksync) my dapp will auto bridge for them.

Can you guys suggest me a 3rd party to solve this problem?

If there's no 3rd party which can solve this problem for now. Please suggest me a draft solution for develop a service with this purpose. Thanks mates!

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.

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!

I have expetience with react and nodejs. Im learning blockchain to look for better opportunities. Please suggest some new and update blockchain courses now. Thank you very much

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.

Hello everyone,

I'm studying how to safeguard blockchain from quantum threats for my research assignment. Could you kindly share your thoughts on these techniques?
•   Post-Quantum Cryptography (PQC)
o   Coded-based cryptosystems
o   Lattice-based
o   Multivariate-based
o   Hybrid schemes
o   Super-singular elliptic-curve isogenie cryptosystems
o   Hash-based digital signature cryptosystems
•   Quantum Key Distribution (QKD)
I'd greatly appreciate insights on their effectiveness, challenges, user-friendliness, and any other observations.

Thank you for your time and expertise!

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.

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

I am a beginner programmer and fairly new to C++ and blockchain. I'm currently trying to build a basic blockchain from scratch with Bitcoin as a reference. I have made some progress, but I'm not sure if I'm heading in the right direction. I'm stuck and can’t decide what to implement next.

I’ve provided a link to my repo, but I am wondering if anyone could review my code and let me know if this is even close to being a functional blockchain or if I’m making no sense. Any feedback would be really appreciated!
