The rise of Decentralized Finance (DeFi) has opened doors for financial inclusion, but for communities with specific ethical considerations, like those adhering to Islamic principles, participating in traditional DeFi can be challenging. This post explores the technical considerations for building a Sharia-compliant DeFi ecosystem, using platforms like Caiz as a potential reference point for discussion.

Key Technical Areas:

Sharia-compliant Asset Selection: Identifying financial instruments within DeFi that comply with Islamic prohibitions on usury (riba) and speculation (gharar) is essential. Platforms might leverage oracles or data feeds to assess the underlying assets' Sharia-compliance.

Decentralized Sharia Supervisory Board: Can blockchain technology create a transparent and immutable record of Sharia compliance oversight? This could involve exploring Decentralized Autonomous Organizations (DAOs) governed by Islamic scholars.

Smart Contract Design: Developing robust smart contracts that automate financial transactions while adhering to Sharia principles is crucial. This might involve features for profit-sharing agreements and ethical investment screening.

Technical Challenges and Considerations:

Scalability and Efficiency: Ensuring scalability and transaction efficiency within a Sharia-compliant DeFi ecosystem will be crucial for user adoption. Innovative consensus mechanisms or Layer 2 solutions might be necessary.

Regulatory Landscape: Navigating the evolving regulatory landscape surrounding DeFi and Sharia-compliant finance will be an ongoing challenge. Platforms need to ensure compliance while upholding Islamic principles.

Transparency and Auditability: Maintaining transparency and auditability is essential for building user trust. This might involve utilizing on-chain data oracles and regular audits by qualified Sharia scholars.

Discussion Points:

What are potential technical solutions for ensuring Sharia-compliant asset selection within DeFi?

How can blockchain technology be leveraged for a decentralized Sharia Supervisory Board?

What are the technical challenges associated with scaling a Sharia-compliant DeFi ecosystem?

Do platforms like Caiz offer any insights into how they might address these technical challenges?

Future of Sharia-compliant DeFi:

Sharia-compliant DeFi holds immense potential for expanding financial inclusion within the Islamic community. By addressing the technical considerations outlined above, developers can create a robust and trustworthy financial ecosystem that aligns with Islamic values.

Let's discuss!

Hi guys,

I'm currently studying at University at the moment and one of the modules is 'Algorithms and Data Structures'. We have been grouped and asked to do a project on "Advance Game Theory for Blockchain Resource Mining".

The problem is - the lecturer has never spoken about blockchain. I kind of understand the point of it from the little reading I did, but it's hard to fully grasp the concept without really knowing what it is we're supposed to be doing.

Whomever is on this forum is obviously clued in enough to know what their talking about, so could somoene help explain this to me in layman's terms? The project is supposed to have an introduction, body and a real world case study. A few questions:

1. Are there any interesting real life cases where this is implemented?
2. How difficult is this to grasp? (I know thats relative but I like to think I'm reasonably intelligent, I've just never thought about blockchain)
3. Does it actually have anything to do with this module?

I'm not looking for someone to do my project for me, but if someone could point me in the right direction or tell me what it is I'm supposed to be looking for?

Thanks in advance guys, I appreciate it.

I apologize in advance if this is the wrong forum for this question, in which case I would appreciate being directed to another sub.

So... long story short, I'm in an email discussion group that suffers routine censorship from the server that the owners of the email group has little control over. Most of the censored words are political and, while used in a politically neutral way by the list members, the server gets triggered and then all of our emails start bouncing instead of being delivered properly. We keep trying to modify our discussions to not trigger the server but it's getting annoying. Like a lot of social platforms these days, the algorithm is deciding for us what can and cannot be discussed, instead of letting the culture of the email discussion group sort it out.

Is there anything out there like a blockchain email discussion server that can't be censored by big tech? Everything seems to be a subsidiary of the big tech industry now and is bound by using the dictates of their political algorithms. At one point, our entire group got censored (auto-suspended by the email server) because a member in the group mentioned that they almost died from an allergic reaction to a certain drug.

We want the freedom to discuss what we want to discuss and some of us wonder if maybe blockchain tech is the solution. Instead of the discussion group being held in one server at one location, maybe it can be spread out using blockchain, such that each member of the group somehow contributes to the totality of the group.

Maybe I am not understanding blockchain enough to explain my thinking properly, but I hope I've given enough info to go off of. Thank you!

For context, I’m a cloud engineer looking to branch into blockchain. I’m really interested in solana and eth chains and would love to explore some courses or learning materials that are blockchain specific but in rust.

I’m cloud affluent (obviously being a cloud engineer) and write automation in python, JavaScript/typescript all day. I wouldn’t say I’m a software engineer but definitely at a point I can catch on quick.

What are some great rust blockchain development resources? Any courses or great books out there that can at least help me build a solid baseline to steady state?

Title pretty much says it all…

Though, I’m more interested in real depth conversations that expand beyond the scope of sensationalism and lean more into expert abstraction, analysis, technical design and architecture. Some that are dialed in on good economics would be great too but also looking for crypto breakdowns that are business functional and not just economically driven.

Thanks in advance for the recommendations!!

We are using Hierarchical Deterministic Wallets to generate custodian wallets of user. It uses a mnemonic phrase to generate child wallets. Each child wallet has a path like this "m/44'/1'/0'/0/0". using a specific path and mnemonic to generate a child wallet will always return the same public and private key pair. So instead of saving private keys of each wallet what if we save path of each wallet, and whenever we have to perform a transaction from that wallet. we can just get private key using that path. In this way we dont have to go through the process of securely saving private keys of all wallets. Instead we just have to make our mnemonic as secure as possible.
It is a good security approach ?

Hi folks, guy with a different background here seeking for advices.

Yesterday i came across a Davincij reel suggesting to use a dedicated pc for managing crypto and specifically a chromebook since it's not expensive.

I already have 2 cold wallets (trezor and safepal), specific mail address for each exchange, multiple exchange accounts with added layer security, google titan key, passwords stored in a physical external hd would it make sense to move onto a chromebook?

Considering that a chromebook is probably more performing that the actual one i'm using lol.

Using a vpn like proton would make another difference or it doesn't?

Thank you everyone

Hello, I'm Mael, a data science student in Mexico, I have a few free hours a day that I would like to dedicate to developing myself in the world of blockchain development. Any tips, books, courses or resources that can help me? Thanks for reading, have a good night.

I like the assumption that every trade made on a CEX like Binance (not DEX) is registered somewhere and can therefore be found.
The following questions come to my mind:

1. Is it?
2. A deposit/withdrawal has a Txn hash that makes it possible to view it in the blockchain. Does a closed trade also have this and where can you find it on the CEX and how to use it in the blockchain (if applicable)?
3. Which wallet is used? Obviously not the one I deposit/withdraw crypto from, but one from the CEX itself, how do I know which one it is? Can I find my trade there? Are there specific wallets for certain trades? Are these wallets permanently linked to my account or are they random?
4. Is there a way to view the history of an order book of a particular pair on a CEX and can I find my trade there and how? I know there is a trading history in my account but that is not what I want to know.

Please provide accurate and detailed information in your comments.

Question.. and you all can roast me its fine. After the Halving, for example) can an S19k Pro just mine another coin on the SHA256 algorithm that will be more profitable? I am interested in getting into KASPA however i want to utilize the S19k Pro on nicehash post Halving..

Hey everyone, I've recently made the decision to dedicate a few hours each day to learning about blockchain technologies and cryptocurrencies. My goal is to acquire a deep understanding so I can start investing in crypto in the future.

I'm not looking for quick gains or aiming to multiply my investment by 100x in a matter of weeks. Instead, I'm focused on building a solid understanding of the fundamentals of the technology and crypto investing.

Are there any books or online courses that you would recommend that teach the fundamentals in a comprehensive and detailed manner

Dear CryptoTechnology community!

I need urgent help, and I think here is just the right place to ask.

So maybe you guys have seen these types of crypto scams where these seemingless helpless "people" post their seed-phrase with a wallet with a few thousand USDT and they pretend that they don't know how to cash it out.

And when you type in their seed-phrase (photo) you will actually find a wallet which has a few thousand USDT coins on it, and you could potentially cash them out yourself. But there is this one hook, the USDT coins are on the Tron chain and there isn't enough gas in the form of TRX on the wallet.

So you think to yourself, that you just have to send some TRX and you will be 3000$ richer. But it will never work out because the gas you send will be immediately stolen and sent to the scammer.

I paired up with a friend of mine to "scam the scammer". we sent just the right amount of TRX and tried to be quicker. We would then immediately swap the USDT to Matic and then send it to OUR wallet.

For around half a minute we even had enough gas on the wallet!

But then the wallet would say "service error" when trying to swap.

Now we are wondering if anybody out here knows more about this scam and how to outplay it.

Thanks for all answers in advance!

Is there a software that can scan every single wallet on the blockchain? And take note of the wallets that outperform and are always successful with trades? I’m thinking of making a SaaS that is able to do this and sell its ability to be used each month.

So people basically pay my website $100 a month and they get access to a tool that shows the best wallets and alerts them when those wallets buy/sell.

Would it be possible to create something like this? For example, a coin that's pegged to the price of a basket of select assets (ex. Oil stocks), or even something that inverses said basket of assets?

It would almost be like an ETF but in the form of a token/coin. I've heard mixed reviews and can't get a clear answer on this. Would really appreciate some opinions/advice.

Hey guys, I am 21M and I have been coding mainly in Swift / SwiftUI & Python for years. I have dabbled in Cyber Sec and love it. I came across "Blockchain technology" in specifically DEFI and it really piqued my interest. I believe it has a future in the world of security and it could be adapted by specific fields. My only internal conflict is that everything i see about it on reddit is negative. People saying it will be obsolete, that its useless etc. etc. . I am a solo dev and currently not in school for financial reasons, I'm saving up to go back but in the mean time I want to create some powerful products that can change lives. I'm not asking for the product but the field to learn. I have learned AI/ML but I think it is just going to be too competitive and be the thing everyone is learning. Just difficult to not only get a job in but also create something unique in. As most of us do, i want to create something that can change lives from my computer. I'm looking for something to learn that's new that has a promising future. And before I devote months of time into learning solidity and Blockchain tech.... I want to know if it is worth it or not. I haven't found much posts that were more recent. thanks....

I know about 'Mecenas' [1] 'Last Will' [2] (thanks Karol for the correction!) but I am looking for alternatives, even proposals that are well described but perhaps not yet implemented.

One aspect I'm looking for (but your suggestions don't need to cover this):

• quantum computing resistant according to today's knowledge. I don't mean this to require that the funds or the data permitting access to them are unlocked on a QR blockchain, but that techniques used to release access to those funds/data are considered QR today.

Some years ago I decided to specialise myself in Cryptography. I’m now about to end my Master’s degree, and I feel ready to delve deeper into the details of blockchain tech, from a technical perspective. Do you have any recommendations for the roadmap I should follow? My final objective would be to be capable both of contributing to the development in an existing community and to come up with my own ideas. However, from the perspective of someone who has spent years approaching this from a deep mathematical perspective, I don’t think online courses such as Udemy’s are something I look forward to watching. So what should I do?

Hello, I am looking for a book that will be able to give me a really good in-depth understanding of the technologies, protocols and languages used within the blockchain space. I am a software engineer so I am fairly tech savvy and I am wanting to increase my knowledge in this space so when I read a new projects whitepaper and the descriptive details about what sort of "innovation" they are doing within the blockchain space, I can actually follow along and be able to detect if it's worth investing in. Being able to understand what contribution companies are making technologically for things like blockchains, smart contracts, decentralisation etc, not just the broad description of how they are changing the space, but understanding it from a technical point of view.

I recently gave a talk on this at ethdenver and someone said I should post it here for the tech.

Basically a little over a year ago some others and I formed a group to build some dapps we were interested in. During the course of development, we realized there was a significant gap on the crypto side for what we wanted to do, which was to award users with small parts of larger NFTs and let the users compose together their data into what they want.

So we set out and ended up building a full stack system called Patchwork which goes from base contracts through protocol and development tools. Will link at bottom for those interested. The workflow is that a developer, perhaps familiar with ORMs and conventional app data modeling, models up their data with JSON and then runs it through a tool that produces contracts that efficiently pack the data and support the relationships between the models. A protocol enforces the relations and data integrity and there's a ton of other stuff allowing for contracts to extend other contracts permissionlessly, per-field collaborate data permissions, minting, accounting and a thousand little details. The system uses 721s as primitives and works with accounts, 721s and 1155s.

Here's the link - https://patchwork.dev

This is pretty new so would love feedback. Let me know if you have questions and I'll do my best to answer here.

Hey everyone,

I've been following the discussions around Bitcoin's scripting language, and I stumbled upon something intriguing: the proposal to bring back OP_CAT, a previously deactivated opcode. It got me thinking about the potential implications for Bitcoin's future.

So, what do you all think about OP_CAT? On one hand, it seems like a powerful tool that could unlock new possibilities for smart contracts and enhance Bitcoin's functionality. But I've also heard some concerns about its past issues with script size and potential risks.

From what I understand, OP_CAT enables the concatenation of two values on the stack, which could lead to more expressive scripts and innovative applications like decentralized file hosting and improved multi-signature schemes.

But I'm curious about the downsides too. Some folks have mentioned worries about script inflation and community divides over its adoption.

I've seen examples of OP_CAT in action, like in Bitcoin Cash and Liquid BTC, where it's been used to improve scaling and enable smarter signatures.

Overall, I'm wondering if the benefits outweigh the risks and if the reintroduction of OP_CAT could truly be a game-changer for Bitcoin.

What are your thoughts? Let's discuss! 🚀🔮

With proof of work, a node can easily look at a chain and discard if if the hashes are below the target. Any fraudulent chain cannot compete without being mined by over 51% of the hashrate. But how is this the case in proof of stake? What's stopping a bad actor from making a fake chain that is longer than the real one? Surely there's no way to validate it, as there is no "proof of stake" in the actual block.

I thought that maybe the last block's hash could be used as a seed for a weighted random selection of the next validator. That way the next validator can be predicted. And each block could be signed by it's validator to proove that it is genuine. But a list of current staking nodes would be needed to select a validator, which is constantly changing. That would mean that there would be no way of verifying that a validator of a block was selected fairly. Am I missing something?

TL;DR at the end. I run a small construction LLC in TX as a side hustle. Good news is, things have really picked up for me and I’m considering going full time!

But before I do, I need to get all my ducks in a row. One of those ducks is receiving client payment.

To give you an idea of the size of my operation right now - I don’t really consider taking on work unless the job totals $40,000 or more. This is the average cost of a small / medium kitchen remodel in my area.

If I take on a job for $40,000 I’ll likely have at least 2 invoices to send to the client. The initial 50% deposit for $20,000 to buy materials and pay subcontractors, and the remaining $20,000 upon completion. (It’s never this simple, but dumbing it down for the sake of discussion)

Here’s the problem: when a client pays an invoice digitally (95% of them want to… nobody really carries check books anymore), that $20,000 takes 7-10 business days to hit my account.

This means that I have to convince my client to pay me $20,000 almost 1 month before I step foot on the job (2 weeks for the payment to clear and 2 weeks to gather materials, pay subs, etc.)

So….. can crypto payments help remedy this? Is there an actual use case for receiving large payments instantaneously? The more user friendly, the higher likelihood my clients will get on board.

I do not wish to hold crypto as a business, but rather USE crypto as a means of fast USD payments. I also really want to support and grow the crypto community.

I also am having a difficult time finding wallets that I can set up as a BUSINESS. I have to keep my business and personal finances separate. If I don’t, it negates the point of operating an LLC.

Strike on the Lightning Network seemed promising. Their app allows users to send and receive cash just like Venmo but it uses the BTC Lightning Network.

Client Sends USD> Strike converts USD to BTC>Lightning Transfer of BTC to Merchant > Strike automatically Converts BTC back to USD > Merchant receives USD

Sad thing is… Strike has daily limits that fall well short of the $20,000 example. I looked into Cash App but it has the same limitations.

A quick fix for me is to sign up for “instantaneous payment” in QuickBooks… but the fees are hard to swallow. In the $20,000 example, I’d have to pay QB $300 for an “instantaneous payment”. Like I mentioned earlier, I really want to support the crypto community any way I can.

Any and all help on coming up with a solution would be appreciated!

TL;DR Is there a crypto payment system I can use for receiving large transactions ($10K-$20K at a time) for business? The more user friendly, the higher likelihood my clients will get on board.

Alright, so I run a business and after a few clients paying in crypto I have decided to buy a hardware wallet, specifically the Trezor Model One.

As of right now, I have just been using wealthsimple (Canadian), and they have what seems like quite high fees, so. I would like to switch wallets.

For the crypto payment system I am required to have my own keys, and so that is why I am getting the hardware wallet.

Once I get the wallet, can I transfer all my funds to the wallet and use it alone to send receive, buy, and sell my crypto?

I understand hot and cold wallets for the most part, but I am not 100% on how I would go about crypto activities when I get my wallet.

So what I ask is first: Do I need to use an “exchange” paired with my wallet?and secondly, if I do have to use an exhange, does anyone have any recommendations with cheap fees? So far I am thinking about NDAX and I have heard great things about them.

Also, closing note, can I pair the hardware wallet with a hot wallet on my phone???

Super confused, any help is appreciated, thanks.

I know if you have an incorrect address you usually will not get your transaction back if it’s lost. I did read that it’s possible to get your transaction back if it was the correct address but wrong blockchain or network? I was using Coinbase trying to send USDC to Binance through Ethereum as USDC; I accidentally sent USDC to Base instead of with Ethereum. Obviously it hasn’t arrived. 🤦🏻‍♀️😂 I opened an account with Basescans Block Explorer, now I’m a bit lost on what I need to do next. Im not fully understanding how to connect the transaction to my account, and what I need to do after to reverse it or correct it.

Let's say we have some funds on an Ethereum layer 2 like Arbitrum, Optimism, zkSync etc.

What happens if layer 2 is halted (say indefinitely)? Can we still recover funds from layer 1?

The fact that layers 2 commit transactions on layer 1 makes me think that this should be possible, on the other hand the fact that we have to bridge funds from layer 1 to layer 2 and viceversa seems to indicate otherwise.

Can someone clarify?

I’ve had this idea for a project to place a QR code hidden somewhere and whoever finds it and scans it gets a crypto reward. Has this been done before?

I can see Nvidia offering peer-to-peer LLM services for generative AI, for a fee or for donating hash with their GPUs, during periods when the GPU is not being used by the user.

Realistic or will some kind of currency backed by blockchain accomplish this?

Hello everyone,

I'm currently delving into the fascinating intersection of blockchain technology and the music industry, particularly focusing on the utilization of Non-Fungible Tokens (NFTs) for music leasing and full ownership rights transfers. The core idea is to create a decentralized marketplace, similar to platforms like BeatStars and OpenSea, but specifically tailored for musicians and producers to lease or sell their instrumental beats, soundkits, and drumkits.

Here's the concept:

Leasing Beats as NFTs: Producers can list their beats for "leasing," where an NFT represents the right to use the beat under specific conditions (e.g., duration of use, type of usage, royalties per use), but not full ownership. Smart contracts would automate the terms, ensuring transparency and automatic royalty payments.

Selling Full Ownership Rights: Alternatively, full ownership rights can be transferred through the purchase of a different type of NFT, detailing the transfer of full rights to the buyer, including any agreed-upon royalties to the original creator in case of further usage or resale.

Discussion Points:

Technical Feasibility: How viable is this concept technically? Are there existing blockchain platforms ideally suited for this kind of marketplace that balances efficiency, cost, and user experience?

Smart Contracts for Royalties: How can smart contracts be designed to handle complex and negotiable terms, like variable royalty rates and rights management, in a user-friendly manner?

Legal and Regulatory Considerations: Given the intricacies of copyright laws and digital rights management, what legal frameworks and considerations should be taken into account to ensure compliance and protect all parties involved?

Market Adoption and User Experience: How can we encourage adoption among musicians and producers, ensuring that the platform is accessible and provides tangible benefits over traditional music licensing platforms?

I'm eager to hear your thoughts, experiences, and any insights you might have on the potential challenges and solutions for implementing such a platform. Let's discuss how NFTs could revolutionize music leasing and ownership rights in a decentralized environment.

Looking forward to an engaging and informative discussion!
