Are blockchain search engine ICO's going anywhere?

Presearch https://www.presearch.io/ A search engine which will be blockchain based is on the horizon. Another based on Ethereum is BitClave and another is Nebulas.

To invest in thse ICO's is risky; any ICO is.

Preasearch has one shareholder in its presale phase one, that's not so worrying, phase two they are to move to another country, other than their current base in Canada. There is no clear description of how the search engine will operate, other than mentioning recruiting teams of data scientists and User Interface designers to build it all! What are they themselves building?

Google has lots of such people already and a good head start. Where is the unique new strategy?

Also it states in the white paper that there is no guarantee of a product nor any actual tokens. Yes I do understand that they have to cover themselves legally and not give certainties, but all of this leaves us giving them a great big lump of trust. They need to keep their propitiatory secrets at least until their open source first release, anticipated 18 months after the ICO sale. And the platform is based on Ethereum.

YES INDEED WE DO WANT A BLOCKCHAIN BASED ALTERNATIVE TO GOOGLE, BUT WISHFUL THINKING MAY NOT CUT IT.

There are several search engine blockchain ICO’s currently: BitClave, and Nebulas, and probably more to come.

BitClave, https://bitclave.ws/ does show apparently test searches on a mobile phone on its website. Their search looks limited to buying cars and job recruitment, well at the first stage. They seem to be aiming at cutting out advertising middlemen, but it is an advertising variant. It does NOT look like it is addressing the overall search issue, that is a huge task, and is simply an advertising platform on a block chain; using Ethereum. So BitClave holds out no promise of a full alternative search engine to rival Google because it is an alternative advertising service.

Nebulas, https://nebulas.io/ has it in its name, for it is somewhat nebulous, the only real focus in its white papers (tech & none tech) is that it is clearly for searching data on interconnected blockchains, not on the wider internet (Googles domain). Well we will need a blockchain for whats on blockchains if they all materialise into real applications.

At best Nebulas is crypto unclear and appears to rely on 'bookeepers' doing some mystifying function, and those to be based on Ethereum are far to slow for such applications and the white paper technical’s are not explaining in any clear terms (some in bad English) how to do any actual blockchain search criteria or examples. None are in my view able to take on a Google replacement role.

A proposed search engine capable of displacing Google looks a long way off but is not impossible, these that are at least claiming to go into the shallow waters of searching the internet, err the blockchain part of it, are taking a very cautionary technical route.

Maybe we need an entirely different approach?

I want to believe.
