Yes, Bitcoin solves BGP (in some way). It solves also a bunch of other completely unknown problems:

* how to prove some information existed at a certain time

Incorrect. It only proves some information existed at a certain block. There is no way to ~~put~~[objectively prove] a clock time in the block chain.

* how to create a public ledger of ownership

Incorrect. A longest-chain-rule (LCR) block chain records non-conflicting state transformations. That isn't limited to a ledger of ownership.

* how to issue a currency without requiring a nation state army to enforce scarcity

Incorrect. A block chain can distribute tokens. That doesn't guarantee anything about it becoming a currency and being immune to nation state armies. If not immune (i.e. not defensible against), then 'without' is incorrect. (it doesn't even guarantee the distribution won't be centralized by mining farms)

* how to reach agreement over a communications channel on value

Again you are pigeon-holing what a block chain does. Again a longest-chain-rule (LCR) block chain records non-conflicting state transformations.

E.g. last year there has been 1B$ investment in this area, and there been almost no progress at all in terms of advanced applications (just an increase in noise levels).

Thanks for ignoring my progress and thereby insinuating my sharing/progress has been noise.

I think the possibilities are largely not explored.

I appear to be reasonably skilled at distilling to the generative essence and I will assert that there isn't a large space of possible designs that will work to eliminate the centralization issue. Mine seems to be the only possible one.

Many also don't know the pre Bitcoin designs, Bitgold and b-money, which are also helpful to consider, see http://www.weidai.com/bmoney.txt and https://en.bitcoin.it/wiki/Bit_Gold_proposal . Actually quite surprising since satoshi said Bitcoin is an implementation of those ideas:

Bitcoin is an implementation of Wei Dai's b-money proposal http://weidai.com/bmoney.txt on Cypherpunks http://en.wikipedia.org/wiki/Cypherpunks in 1998 and Nick Szabo's Bitgold proposal http://unenumerated.blogspot.com/2005/12/bit-gold.html

Now that is noise or at least veering very far from a solution to the problem this thread raises.
