1  Alternate cryptocurrencies / Altcoin Discussion / Re: List of Ethereum Clones and Forks on: April 01, 2024, 08:42:12 PM
ETH is more than a single coin. It's not simply Ethereum, it's also all the dozens of L2 cryptos that use the power of ETH to secure their blockchains. Bridging has made EVM compatible crypto a whole ecosystem.  Perhaps the reason there are fewer clones are that instead of something totally new, the people created a L2 that still ties into the ETH network while doing things different than ETH.

However the barrier to entry is low for a clone or fork, if a person or group feels like they have a better solution then go ahead. The community will decide if it succeeds or not.

Tokenizing real world assets is only going to be more common. For a project I was involved with, we spoke at length with lawyers on tokenization and we couldn't figure out a way to allow our project to work for the average person. Accredited investors would have been acceptable legally, yet that only applies to people with provable million+ worth of assets excluding the house.  Love how the average person can get into hundreds of thousands of debt but they can't toss $100 into a non public asset! 

If you've figured out how to get around this limitation, great!

I'm all for crypto being anonymous, distributed, buyer beware. Unfortunately, as soon as it touches fiat currency the feds have other ideas.

If you're a US citizen then you're opening yourself and any US users up to the issues that localbitcoins had. This includes users being charged with money laundering and unlicensed money exchange services.  You really need some good crypto legal advice to keep yourself from running into issues. The gov won't care if it's only a hobby project.

Not trying to be a downer, I firmly believe the more devs working in crypto the better. However, I've been around enough to know that any service needs a legal review before it goes live.  If you aren't friends with any lawyers look around. I had one that I could pitch projects to and he'd gladly listen and tell me what would be needed to launch without any charge. He would only charge if I then asked him to do work. He said it was a nice change from the typical business stuff he did.
4  Bitcoin / Project Development / Re: How do I tell people about my crypto escrow services/server? on: March 26, 2024, 04:36:27 AM
Back in the dotcom days I was involved with a business auction service with built in escrow services.

Are you in the US? If you haven't, get a good lawyer that knows about escrow services. Many states had various rules about what requirements are needed to call yourself an escrow. I know initially we had to not claim to be an escrow in California because you needed to be a member of a certain trade association. This is decades out of date info but expect lots of hoops.  As crypto has become mainstream I would only expect more hoops.

As to marketing the service you'll have to dox yourself so people know who they are trusting. Also be very upfront about where funds are held. Also be sure you can publicly say you are using them, one bank didn't like us using their name in any fashion without it being cleared by their legal.


5  Alternate cryptocurrencies / Altcoin Discussion / code snippet: how to get NFT ownerOf on: March 05, 2022, 09:38:54 AM
Is this the right topic for a quick code example?

I had need to find ownerOf on a private Ethereum test network. The library being using was missing the call. A workaround was far less complex than fixing the library. It's a quick hack but it may help others in the same situation. Plenty of other examples were found to modify to get here, thanks other random devs.
 
Needs - geth

First, you need to define an ABI. The Ethereum Application Binary Interface (ABI) lets you specify how to interact with a contract and return data in a format you’re expecting. I only care about ownerOf.

Add a new file, ownerof.abi :

Code:
abi = [{ "constant":true,"inputs":[{"name":"tokenId","type":"uint256"}],"name":"ownerOf","outputs":[{"name":"owner","type"
:"address"}], "type":"function" }]

Then a quick script with two passed arguments the NFT contract address and the tokenID of the NFT you are querying for ownership: NFTcheck.sh

Code:
!/bin/sh
/home/geth/geth -attach << EOF | grep "ADDRESS:" | sed "s/ADDRESS: //"
loadScript("/home/geth/ownerof.abi");
caddr = "$1";
c = web3.eth.contract(abi).at(caddr);
d = c.ownerOf.getData($2);
var addy = web3.eth.call({to: caddr, data: d});
console.log("ADDRESS: " + addy);
EOF

Then run this command like so ./NFTcheck.sh <contract> <tokenID>

You can run the script from any other language/script, for example PHP would use exec().

Note, the address returned is a byte32 and all lower case. You will need to slice the last 40 characters and use a checksum address to get the proper upper and lowercase of the actual address. For comparison against a known address it works fine.

The web3 that comes with geth is 0.20.1 so you can't use toChecksumAddress() on the return.


If there are better ways feel free to post.

I did mention there is collateral that can be discussed. The post is a general request, I'd prefer to talk over the details one on one - use of funds, project overview, collateral, loan terms, etc. 

Not trying to be evasive, simply trying to make sure I don't break any of the variety of laws about funding and dealing in an open forum.
7  Economy / Lending / Re: Business Loan to refresh crypto gamified auction site, 50,000 USDT, 6 month term on: November 28, 2021, 05:20:05 PM
You are both correct that it is a big ask and people should be skeptical. Most of the time something like this would end up having a new business partner or investor, yet this isn't an angel network or crowd equity site so I can only ask for a loan.  

Use of funds is more than a simple reskin and adding a few tweaks. There is also an additional service that will be added that will compliment what is already there.

A full use of funds and project overview is available, I'd prefer to speak one on one about the details.
There is also some collateral that can be discussed.

Bringing the service back up as is and waiting for the income would delay a full relaunch by a few months. It is of course an option yet I'd prefer to move faster than that as crypto waits for no one. I may also go the traditional bank route although my first thought nowadays is to see if crypto can be the solution.

Also, I have seen a variety of business loan structures used.  A business loan can be quite creative other than a simple term and rate.

Options can potentially include percentage of profit for a duration as part of loan arrangement, with some loan requirements lasting beyond loan repayment.  I'm open to discussions.
8  Economy / Lending / Business Loan to refresh crypto gamified auction site, 50,000 USDT, 6 month term on: November 28, 2021, 10:35:12 AM
I ran a gamified dollar auction service for a few years, allowing players to win crypto at below market rates.  The site was moved to a demo mode due to a potential conflict with the 'day job'. That is no longer the case.

I plan to update the service to use non custodial wallets, redo the UX, and add enhanced functionality. I'm a little illiquid at the moment so I'm seeing if this may be a valid way to restart the service.

I'm looking for a business loan of 50,000 USDT with a 6 month term, at a reasonable rate. I anticipate a few month development time before a relaunch and revenue generation begins.
PM me if interested and more information can be discussed.

9  Economy / Marketplace / Re: Trying to buy large volumes of BTC with discount. on: September 08, 2019, 07:22:44 AM
The suggested method was really no more than a glorified localbitcoin process of meet and exchange funds, and hope the wire after the fact is legit?

There are professional bitcoin services that can offer this already, there are professional escrow services to protect both buyer and seller, including those offered by HSBC (mentioned in the steps to handle this).

Of course anyone with 500 BTC today has already eluded the scammers so far, I assume they won't fall victim to something.   
10  Bitcoin / Project Development / Re: Bitcoin Scammer - a proposed resource for scam reports. on: September 02, 2019, 09:13:54 AM
Listing scammers is a whack-a-mole approach and sadly most people scammed are the newbies to crypto who don't even know of this forum. Not to say something shouldn't be tried, but the suggestion to educate users may have better long term consequences. Also the negative trust system does label posts strongly to be careful so there is a basic system in place.

Look at the recent PlusToken scam, it ended up touching up to 1% of all bitcoin which is a huge scam. However the millions of people scammed were new to crypto, mostly talking into it via wechat, and were walked through how to buy in. Unfortunately nothing done on this site would have helped those hit by PlusToken.

Maybe we should ask Craig Wright on how his "Hold my 1 million Bitcoin until 2020" was done?  Grin
12  Bitcoin / Project Development / Re: bash script to automate proccess of sending BTC to other addresses on: September 02, 2019, 04:41:39 AM
If everything is in an array you're almost there. Loop through the array to construct the sendmany variable, adding each address/value.

Each iteration add a comma to the end of the constructed variable, except for the last pair as it is not required.

Then perform the actual sendmany using the variable you have just created.

Are you on linkedin? Even if you're not looking for work if you have crypto projects listed in your profile you will get contacted by headhunters.

14  Bitcoin / Project Development / Re: How to find venture capital investors? on: September 01, 2019, 07:04:19 AM
This is crypto, the ICO and IEO route is the crypto answer to Venture Capital. Yes ICOs have changed over the years but a few billion has been raised this year so far.

15  Bitcoin / Project Development / Re: I want to make an AdWords-style website. on: September 01, 2019, 06:52:55 AM
Not all the time a brilliant idea requires LOTs of capitals. For example, Facebook started from a room without thinking about the future but as a fun project. The idea was good, it made him billions. And now Facebook is the 2nd biggest giant after Google.


While FB started in a room it took real money to get it going. He was able to show enough of a working product to show investors, which gave $500K for 10% of the company. An idea is just part of the product, implementation is the hardest part of any project and that usually takes cash. Convincing any website to use your service instead of Google is going to be a real trick.

You are targeting one of Google's income earning markets, the monster in the room. Not to say you shouldn't strive for your dream, just be aware that there are many many companies that have tried and failed to do online advertising and you are focusing on the niche of bitcoin. But I will say that is what makes the Internet so wonderful as the barrier to entry to competing services can be rather small. Good luck!

16  Bitcoin / Development & Technical Discussion / Re: Cryptocurrency that takes fees from miners on: September 01, 2019, 06:22:23 AM
Dash is the biggest coin I can think of that does this. 10% of rewards go to the Dash treasury. Dash established the masternode crypto, other coins decended from Dash's codebase may have similar developer funds.

17  Bitcoin / Bitcoin Discussion / Re: We need a movie about Bitcoin on: August 21, 2019, 06:39:53 AM
Matrix 4 was announced, maybe they'll toss in some bitcoin in there. They did use some basic unix networking tools on a few screens in the previous movies.

Or maybe Satoshi is actually Neo?

18  Bitcoin / Bitcoin Discussion / Re: What do you think about Bitcoin and the games industry? on: August 21, 2019, 06:00:34 AM
The mobile space will not move to crypto in game as it would hurt Google and Apple's profit share of in app purchases. In fact the development agreements don't even allow sharing of in game currency/coins between 2 games. There have been a few ICOs that were successful and are working on making a crypto app store however the general public will be hesitant on allowing foreign apps on their smartphones.

The gambling industry has embraced crypto because banking regulations can be brutal for that space.

PC / browser games will probably be the best bet for crypto usage to come about. It won't be mainstream anytime soon.




19  Bitcoin / Bitcoin Discussion / Re: WHEN THE LAST COIN HAS BEEN MINED. on: August 21, 2019, 05:48:27 AM
Over 42 BTC in transaction fees were given to miners in the last day. Even without new coins being minted there will always be incentive to mine.

https://bitcoinvisuals.com/chain-fees-day

With the peak being nearly 1000 BTC in fees in one day the potential in a hundred years could be significant.

20  Bitcoin / Bitcoin Discussion / Re: Machine Learning is Needed to Detect Money Laundering on: August 20, 2019, 05:05:05 AM
It's not like money laundering is a crypto only issue. Of course if you're a major bank you can do it and pay a fine, without getting in trouble. At least with the blockchain the dirty laundry is harder to hide.

https://www.marketwatch.com/story/netflix-documentary-re-examines-hsbcs-881-million-money-laundering-scandal-2018-02-21

"HSBC, Europe’s biggest bank, paid a $1.9 billion fine in 2012 to avoid prosecution for allowing at least $881 million in proceeds from the sale of illegal drugs. In addition to facilitating money laundering by drug cartels, evidence was found of HSBC moving money for Saudi banks tied to terrorist groups. Even though federal investigators found evidence “that senior bank officials were complicit in the illegal activity,” no HSBC executives faced charges for their actions. "
