Hllo

I want to build from a conversation that I had w/ Peter (T?) regarding the
increase in block size in the bitcoin from its's current structure would be
the proposasl of an prepend to the hash chain itself that would be the
first DER decoded script in order to verify integrity(trust) within a set
of transactions and the originiator themselves.

It is my belief that the process to begin a new encryption tool using a
variant of the WinterNitz OTS for its existential unforgeability to be the
added signatures with every  Wallet transaction in order to provide a
consesnus systemt that takes into accont a personal level of intergrity for
the intention fo a transaction to occur. This signature would then be
hashes for there to be an intermediate proxy state that then verifies and
evaluates the trust fucntion for the receiving trnsactions.  This
evaluation loop would itself be a state in which the mining power and the
rewards derived from them would be an increased level of integrity as
provided for the "brainers" of a systems who are then the "signatuers" of
the transaction authenticity, and additiaonally program extranonces of x
bits {72} in order  to have a double valid signature that the rest of the
nodes would accept in order to have a valid address from which to be able
to continuously receive transactions.

There is a level of diffculty in obtaining brainers, fees would only apply
uin so much as they are able to create authentic transactions based off the
voting power of the rest of the received nodes. The greater number of
faults within the system from a brainer then the more, so would his
computational power be restricted in order to provide a reward feedback
system. This singularity in a Byzantine consensus is only achieved if the
route of an appropriate transformation occurs, one that is invariant to the
participants of the system, thus being able to provide initial vector
transformations from a person's online identity is the responsibilty that
we have to ensure and calulate a lagrangian method that utilisizes a set of
convolutional neural network funcitons [backpropagation, fuzzy logic] and
and tranformation function taking the vectors of tranformations in a
kahunen-loeve algorithm and using the convergence of a baryon wave function
in order to proceed with a baseline reading of the current level of
integrity in the state today that is an instance of actionable acceleration
within a system.

This is something that I am trying to continue to parse out. Therefore
there are still heavy questions to be answered(the most important being the
consent of the people to measure their own levels of integrity through
mined information)> There must always be the option to disconnect from a
transactional system where payments occur in order to allow a level of
solace and peace within individuals -- withour repercussions and a seperate
system that supports the offline realm as well. (THis is a design problem)

Ultimately, quite literally such a transaction system could exist to
provide detailed analysis that promotes integrity being the basis for
sharing information.  The fee structure would be eliminated, due to the
level of integrity and procesing power to have messages and transactions
and reviews of unfiduciary responsible orgnizations be merited as highly
true (.9 in fizzy logic) in order to promote a well-being in the state.
That is its own reward, the strenght of having more processing speed.


FYI(thank you to peter whom nudged my thinking and interest (again) in this
area. )

This is something I am attempting to design in order to program it. Though
I am not an expert and my technology stack is limited to java and c (and my
issues from it).  I provided a class the other day the was pseudo code for
the beginning of the consensus. Now I might to now if I am missing any of
teh technical paradigms that might make this illogical? I now with the
advent of 7petabyte computers one could easily store 2.5 petabytes of human
information for just an instance of integrity not to mention otehr
emotions.



*Also, might someone be able to provide a bit of information on Bitcoin
core project?*

thank you again. Damain.
