Oyster Pearl was an ICO that didn't go so great but the dev team been active detailing how they are going to accomplish their roadmap. There are a lot of risks involved in this coin but for the reason's below, I going to hodl a little bit and see how 2018 treats it.
Oyster Pearl is a ERC20 token that utilizes Ethereums smart contracts as well as IOTA's tangle. It will be used primarily as a decentralized storage ledger. Pearl is unique in that it tackles two problems, burdensome advertisements and reliable decentralized data storage.
We all hate advertisements on websites. I can't stand visiting the webpages of the Wall Street Journal and eBaumsworld (I have diverse taste) and being asked to disable my ad-blocker because they rely on ad revenue. It's annoying but its a necessary evil, or at least it was. Enter Oyster Pearl. Websites will be able to include a single line of code in their web page's code which will use spare CPU and GPU space of their visitors for POW. The POW is two-fold. The GPU will be used for IOTA POW while the CPU will be used for a unique "oyster-hunt POW" which from my understanding, ensure all the Pearls are not instantly made available to the node holders which secures the hosted data. Effectively, the web-page will no longer have to rely on annoying advertisements to generate revenue and the web-page visitor will have a seamless web-browsing experience.
