I did not run the tests for i0coin, but on the merge-mining branch of Namecoin from which i0coin is forked. i0coin itself only changes the chain parameters and branding. The regtests and unit tests for Namecoin (and the "just merge-mining" branch) are checked for every commit there.
Most cryptos are either exact clones of another, or just slightly different. I0coin's change in parameters from Bitcoin are small but gives it capabilities which improve on Bitcoin.
I0coin's features (many of which are improvements over Bitcoin):
> 6.7 times faster block times than Bitcoin so users can fully confirm txs in 9 minutes, not an hour like Bitcoin.
> 6.7 times the transaction bandwidth of Bitcoin even without block size increases.
> Faster mining rate early in I0coin's life means its 21 million coins are mostly mined already. Near zero currency inflation means new I0coin generation doesn't devalue existing coins.
> Merged mining is more energy efficient because it shares mining resources. This also offsets a reduced desire by miners to mine I0coin since it now has a small block reward. I0coin has remained in the top 5% of cryptocurrencies when considering network hash power.
> Block chain compatibility with all of Bitcoin's block chain technologies.
> I0coin also serves to expand overall cryptocurrency bandwidth. It's been well advertised that Bitcoin cannot even come close to fiat currency transaction volumes by itself. Additional cryptocurrencies which are closely aligned with Bitcoin can share the bandwidth.
6.7 more transaction bandwidth? Well this means more bloat and probably cheaper dust attacks, perhaps a candidate for a unit test because i bet by simply "tweaking parameters" you will degrade a security aspect od the underlying mechanics which are all assuming certain thresholds.. This is the problem with most devs in coins they simply do not understand software enough to fully comprehend what they are actually doing but just a get rich quick by trying to fool others that hey ive offered a betted alternative which is untested and probably full of hidden bugs of which are the worse kind.
