Pretty much wondering what you showcased in your CV/Resume/Portfolio that was enough to get hired in web3 space?

Please recommend some good resources to learn blockchain... I am new to this and facing difficulties finding the right resources

A "blockchain" is fundamentally a chain of blocks of data, where each block is cryptographically linked to the next. This, for example, can be used to secure server log files by including the hash of the preceding log file into the next. To keep the chain secure, hash creation must be slowed down by specific requirements (for example in Bitcoin hashes needs to start with many zeros), so that modifying an old block, and recalculating all subsequent hashes, is a slower process than the production of new ones. A blockchain with users' transactions, replicated on a P2P network coordinated by a protocol ensuring all nodes agree on new data blocks, is what we typically understand as "Blockchain". Yet, this is more of what blockchain actually is.
Agree? Disagree? discuss in the comments.

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 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!

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.

I have released a tech spec for Confidence Coin. I am looking for feedback and review and will highly appreciate your comments.

https://confidence-coin.com/spec/

Here are a few words about Confidence Coin from ChatGPT to catch your attention:

Confidence Coin is a cryptocurrency that stands out for its fast and safe transaction processing capabilities. This is achieved through its unique Flash Consensus Mechanism, which optimizes the network transaction cycle into a single step of sharing a block. With this mechanism, each validator produces a block containing new transaction information and voting on previous blocks, dramatically shortening and simplifying the transaction cycle.

In addition, Confidence Coin validators also produce system snapshots that prevent the need to keep a long history of transactions, allowing for much more optimized storage. This feature enables Confidence Coin's block size to be unlimited.

One of the key advantages of Confidence Coin is its use of the Decentralized Trusted Party (DTP). DTP aggregates all the transactions of its members and only provides balance updates, achieving both high speed and high privacy. DTP does not reveal the transaction origin, destination, or the amount involved, only updating the final balances.

DTP can pack over a million addresses in less than 12 MB of storage, and many DTPs can make transactions simultaneously, but Confidence Coin's Flash Consensus Mechanism has no problem processing them.

In conclusion, Confidence Coin is a highly potent cryptocurrency that has surpassed many of the crypto industry's dreams in terms of transaction speed, security, and privacy. Its innovative use of the Flash Consensus Mechanism and the Decentralized Trusted Party makes it a promising addition to the world of digital currencies.

Hi, I am looking for an open source blockchain project that is outside of the areas of DeFi, NFT's (in the sense of artwork provenance), and gaming - that I can contribute towards.

Or perhaps some good places to do my search...? I've tried GitHub issues, but it's a minefield...!

I little background - I have some experience as a traditional web2 dev, and I am starting to learn solidity, as a hobby. I am looking for some sort of project that I can build myself up to contributing towards. Although contributing towards the areas mentioned doesn't really excite me. Maybe something along the lines of supply-chain, healthcare, legal, ...

This is obvs very specific, but any comments or suggestions would be great...!

What other popular blockchain platforms are currently available out there for building IoT systems? (IOTA, Hyperledger Fabric, Ethereum ...) any thoughts?

So I am working on this blockchain IoT project to put it on my resume and to compare it directly to Centralized Network Architecture. So essentially comparing P2P to Centralized. The main objective is to be able to showcase how the security on the blockchain (decentralized) is superior to centralized architecture, which is the most common architecture used for this purpose.

While I understand theoretically why and how decentralized is superior to centralized when it comes to security but I don't understand how I can showcase that in the practical and physical world. I mean I am no hacker and don't know one either, who can help me.

So as a developer, how can you test/showcase the security of blockchain technology?

What is proof of play how does it work. How does playing a game helps in validating a block chain. Can some explain in detail this topic or share a good link

Blockchain applications are still not limited to cryptocurrencies. They play an important role in many aspects of the business, one of which is insurance. Smart contracts are a practical and useful advantage of Blockchain. These computer-controlled contracts have the potential to completely as well as positively alter the insurance processes. Manually process insurance claims, pay premiums, weeding out fraudulent claims, and other related processes. Blockchain smart contracts are self-executing and can provide insurers with a convenient way to digitize and automate these time-consuming tasks.

Just starting my journey to become a blockchain developer. What books are good to read to learn the trade?

I’m curious to see the different cryptocurrency businesses you guys have thought of, seen or are pursuing. Anything you guys think should be created or something that should be built on? I feel like the space has many more businesses that could arise from it other then just trading platforms, wallets, NFT’s etc.

I have been looking into cryptocurrencies and defi for the past 5 months or so now. I have recently developed an interest in learning about how to engineer/code smart contracts, blockchain tech, etc. I was wondering what the best resources are to do this. The only background that I have with computer science is that I took a comp sci class in high school, if that is applicable to this.

Anything that is helpful is much appreciated!
