I0coin (I0C), news for I0coin cryptocurrency

I0coin (I0C) is a peer-to-peer cryptocurrency based on Bitcoin with a faster block time and shorter maturity. I0coin is merge mined with Bitcoin to allow for super efficient, low energy mining, and a massive network hash rate. I0coin is the most secure cryptocurrency with a block time faster than Bitcoin's.

ROI is Return On Investment

After buying, selling, mining and staking more than three dozen altcoins it became clear that many coins had some great features but no single coin had everything. ROI Coin is essentially a coin that combines all the very best features of many great coins into one single coin. While most cryptocurrencies focus on and revolve around the coin itself ROI Coin is different. The focus of ROI Coin is the community and the coin revolves around the people that support it.

Abstract
So far, the topic of merged mining has mainly been considered in a security context, covering issues such as mining power centralization or crosschain attack scenarios. In this work we show that key information for determining blockchain metrics such as the fork rate can be recovered through data extracted from merge mined cryptocurrencies. Specifically, we reconstruct a long-ranging view of forks and stale blocks in Bitcoin from its merge mined child chains, and compare our results to previous findings that were derived from live measurements. Thereby, we show that live monitoring alone is not sufficient to capture a large majority of these events, as we are able to identify a non-negligible portion of stale blocks that were previously unaccounted for. Their authenticity is ensured by cryptographic evidence regarding both, their position in the respective blockchain, as well as the Proof-of-Work difficulty.
Furthermore, by applying this new technique to Litecoin and its child cryptocur rencies, we are able to provide the first extensive view and lower bound on the stale block and fork rate in the Litecoin network. Finally, we outline that a recovery of other important metrics and blockchain characteristics through merged mining may also be possible.
