PRA Coin Parameters
The initial goal of this project is to make a straightforward Litecoin PoW clone with better parameters, to become the basis for further work. This one will be used to issue rewards and equity, trade on exchanges and attract hashing power. More experimental or special purpose coins will be able initially to perform merged mining with PRA, and then act as test cases for more advanced PoW, PoS, Difficulty adjustment, Lighting network, and similar enhancements. There has already been a strong interest in building upon Ethereum and Zcash. We could also decide to provide testbed support or rewards to researchers and promising projects. Litecoin codebase, transitioning to , once Litecoin does catch-up with Bitcoin (Linux and Windows wallets and nodes)…
Genesis Block
Every cryptocurrency derived from Bitcoin has a Genesis Block, the very first block in the blockchain, whose creation is hard-coded into the full node code. In order to prove that it's authentic, the usual rules about hashing the Merkle root and the Consensus information apply. So, one has to come up with some seriously magic numbers to put in the code. The established technique, documented in all the coin cloning guides, involves setting the values to zero for the very first run, getting an error message and using the values displayed in the log file to fill into the source code. However, the section in the Bitcoin code that computes the required hashes for debug printing has been removed from…
Difficulty Re-Targeting
Adjusting (re-targeting) difficulty for the PoW is a complex issue with Cryptocurrencies. Bitcoin adjustment every 2016 10 minute blocks (two weeks), is very coarse, and is not usable for smaller coins, in the age of ASIC and GPU farm mining, where hashing on a particular network can change very rapidly, sometimes automated or performed for malicious reasons. A range of algorithms and techniques are evolving and many have been implemented and deployed since. Kimoto Gravity Well (KGW) Nite's Gravity Well Dark Gravity Wave Digishield from Dogecoin had time-warp vulnerabilities but was fixed-up in other coins since. Slingshield also made improvements of some sort. Zcash settled on adjustment for every block, after an extended discussion. They implemented a modified Digishield v3. Despite prolonged discussions, Litecoin…
Free – Cryptocoin Creator and Build-a-Coin
site prizes itself on having created some 1300 coins. And it's possible, as it appears that they do stamp them out for free - if you don't ask for source code or the ability to run it on your own server. If you want those, as any reasonable Altcoin creator would, you are told to email for a quote for a Commercial License. The site itself went through a couple of attempts at a sale on Flippa a year ago - unsuccessfully. Its SSL certificate is expired, and that's why Chrome labels it as Not Secure. Overall, it does not appear recently maintained and does make silly statements, like the fact that it features Elliptic Curve signing, something that all Bitcoin…
