1  Alternate cryptocurrencies / Tokens (Altcoins) / Re: 👏 [ANN] Crypto Accept ($ACPT) - Ecommerce Solution for Ethereum Tokens on: September 28, 2020, 03:39:27 PM
Looks like the app will be an easy way to accept crypto payments. I can see multiple small businesses who may want to dabble in crypto using this as there is no fee to do so like most cc payment processors. Also keep in mind what you accept today should be worth 10x that in the future! Seems nice.
2  Alternate cryptocurrencies / Service Announcements (Altcoins) / PIVX Clones for 1 BTC on: February 02, 2019, 01:05:58 AM
Hello, I am currently looking for clients to provide PIVX clones for an introductory fee of 1 BTC.

Features include any size pre-mine, compiled wallets for macOS, Windows 32/64, and Linux. Customizable master node/staker rewards, etc.

Server nodes can be provided for additional fee. If you are looking for your own blockchain with PoS and Masternodes, let me know.

Looking forward to working with more projects.

Thanks,
Crypto Joe

3  Alternate cryptocurrencies / Mining (Altcoins) / ASIC Mining Altcoin with 181 byte blockheader on: March 18, 2018, 02:53:48 AM
Hello all,

I have been toying around with a Gekkoscience 2PAC with the hopes of possibly getting it to mine a SHA256 alt coin with a large block header. I am editing cgminer and so far I am not having a lot of luck. I have read on Telegram that it can't be done, which makes me want to do it. The header is as follows:

[4] - version
[32] - previous hash
[32] - merkle root
[4] - time
[4] - nbits
[4] - nonce
[32] - stateroot
[32] - utxoroot
[32] - 0's
[4] - F's (ffffffff)
[1] - 0's

Being the alt coin is based on bitcoin my theory is that instead of making the midstate from the first 64 bytes, I could get creative and do the following.
extras = sha256(stateroot + utxoroot + 0's + F's + 0's) - 32bytes ( these values also don't change)

midstate = sha256(First 64 bytes + extras)

This inherently does not crash the ASIC when it runs, but any blocks are rejected. I think it has to do with the regen_hash function that will only accept a sha256 value of 80 bytes. I have tried to make it the 181 byte value and pass in the full header but the 2PAC errors out and won't hash. I am not exactly sure why not, since sha256 should not care the size of the message. At 80 bytes it all runs.

This is a bit of a long shot, but I thought I would toss it out here in case anyone has an idea or maybe assurance that it is impossible.

Thanks,
Joe
