The seminal white-paper, "How To Build a Brain-to-Brain Internet: Proof-of-Cognition Blockchains as a Foundation for Brain-to-Brain Security"  has been floating around the bitcoin dev chat for a while now.

I am opening up an early draft of this paper for public comment.  We are working on a series of experiments that will evaluate the robustness of the verification web in living beings, gathering data for proper evaluation of brain-originated key-generation, and looking forward to developing unconscious neural models for recognizing organisms of the same species. We have submitted a latter version of this paper for publication.

The purpose of this paper is to flip the Internet inside-out-- from a digital-only expanse, to a sub-universe accessible only by a pseudo-anonymous, digital-neurological identity. Long before our thoughts are on the internet, artificial intelligence will invade the web. A digital-neurological identity cannot be impostered by an AI without the ability to convince thousands of humans that an AI is human, as well as the capability of the AI to efficiently model a series of 10-billion neuron brains. It is important we devise a mechanism for securing the communications among biological beings by harnessing the entropy between our skulls. When this computing power is layered among nodes, it will forever be difficult or impossible for an AI to invade the network. If an AI ever did begin to invade the network, the public nature of the blockchain would alert its users, allowing them to (automatically) disconnect their consciences before an AI could attack.

We utilize a 'proof-of-cognition' (POC) blockchain for verifying identities and maintaining a web of human trust. This is not a proposal for a digital currency. Data traded on a POC blockchain has no value. Instead, mutual transactions between two nodes signify an 'acceptance' or 'rejection' of another node's humanity. By accepting and rejecting nodes based on their humanity, we can create a web of human nodes with verified digital signatures. Using these digital signatures, nodes can sign blocks with their identity. A forest of blockchains can be formed where highly-verified nodes are more likely to have their blocks accepted by nearer blockchains. Because mutual transactions quantify trust, double-spends are not relevant, and in fact, would weaken a node's level of trust on the verification web. Cryptographic miners are implanted and inaccessible. A limited hashing power can be assumed for each node, allowing hardware miners to be biologically-powered, and preventing mining from being a waste of energy. While not suitable for currency, a POC blockchain is ideal for identity-verification, given its low-energy usage, decentralization among humans, and robustness against AI attacks.

Digital currency fees are used in human-service transactions. This might be bitcoin's 'killer app'.

i have a solid group of about 5 people, but i'd like to get it to about a dozen.

A proof-of-humanity blockchain would function as an identity network for decentralized elections and governments. Rather than relying on a one-cpu-one-vote protocol, the protocol would be one-human-one-vote. Digitally signed blocks can limit hashing power and prohibit artificial intelligence from overtaking the network. While POW relies on a computationally impossible series of mathematical problems, POH relies on computationally impossible biology.

This is not a currency system; this is not a replacement for bitcoin. Bitcoin is utilized in a POH to prevent spam in brain-to-service connections (though other types of transactions would be feeless, due to their unconscious/involuntary initiation). Thus, the two protocols are complementary. In a couple decades, this network could truly be bitcoin's 'killer app'.

Please e-mail braininternetproject@gmail.com if you're interested in reviewing the paper. Optionally, please describe your involvement in bitcoin (only relevant if I get more than 10 people interested).

"Every miner should sign the blocks that he solves with his own key. After a miner has created a lot of blocks
over month that get accepted by other miners, new blocks of the same miner deserve more trust than blocks
of new miner"

Miners  who are more trusted could then flood the network with 'bad blocks'. It would only take one bad block for a miner to double spend and receive a lot of bitcoin.

A better idea would be to have a cryptographic miner inaccessibly tied to a biological identity. It could sign blocks, as you described, but because the hardware would be rely on tasks performed by the human body, there would be no risk of forgery.

I describe this in my thesis on building a brain-to-brain, 'proof-of-humanity' blockchain. I haven't yet sent it to cryptographers, but I'm interested in receiving feedback.
