Benefits of technology
This approach ensures secure, efficient, and trustworthy confidential data collaboration by providing a single version of truth, non-repudiable transactions, and confidentiality, reducing complexity and confusion in multi-party transactions.
Problems solved by technology
The former often involves multiple communications introducing substantial delays into the process and introduces a plausible deniability for all parties which leads to substantial uncertainty, rechecking, re-verifying and the like.
Finally, each party assembles their own potentially contradictory facts leading to massive confusion and finger-pointing.
The latter, also leads to a situation of plausible deniability and every party having to trust every relaying party.
For example, if person A trusts person B and person B trusts person C, then person A can trust person C. However, there are problems associated with static chains of trust as applied to a confidential collaboration.
This severely limits the applicability of this technique to widespread commerce.
This makes it impractical to use except under very specialized conditions.
A pharmacy cannot trust every patient it encounters to forward a prescription from a doctor to the pharmacy without tampering.
While this might not be a high risk for some prescriptions, it might be a high risk for other prescriptions involving highly controlled prescriptions such as DEA Schedule II Drugs, which include opiates and narcotics.
The biggest problem with certified mail is that the content is not certified.
However, it is also well appreciated that the current state of the art does not work well for confidential transactions.
While these new blockchain confidentiality features will allow hitherto off-chain private transactions to move on-chain this capability is not sufficient in and of itself to enable certified communication and collaboration capabilities like confidential dynamic chain of trust.
This is how a severe form of trust recentralization occurs, even if utilizing a decentralized technology like a blockchain.
One downside of smart contracts is that they become exponentially harder to debug as they get more complex.
However, there is no (currently practical) possibility of overcoming this problem for general smart contracts without severe compromises.
The inability to perform confidential validations is a key limitation of blockchains known in the prior art.
Blockchains known in the prior art are unable to scale to the sizes of the confidential fat twin.
Readers and commenters will not be able to add, modify or delete sections or add other writers, readers or commenters.
One of the major problems with current electronic communication systems such as email is the problem of spam.
However, recipients only receive anti-spam-payouts if they have an on-chain identity.
These are integrated VAP services and are not-separable from the validation service.
However, this structure by itself does not solve other blockchain including scale rate and the problem of orphaned blocks.
The downside of this approach is that it is currently viable for only relatively simple validations and will not allow for more sophisticated validations thus limiting the type and degree of certified operations.
Because the governor cannot read this content, the governor cannot do any validation on this content.
Because SACH is on a public blockchain, it may be subject to being guessed through trial and error since it utilizes a well-known structure.
However, this embodiment requires massive additional trust in the governor relative to the blockchain approach.
Furthermore, the digital signature approach doesn't support fully on-chain fat twins and thin twins.
Said another way, there is no way for it to support fully decentralized, trustless certified messaging and collaboration which is the long-term goal.
With the digital signature approach, all parties could not verify it because in general all parties do not have access to TTN1.
Even for a party that does have access to TTN1, it runs into the lack of canonical SAC issue.

With this digital signature approach, all parties could not verify it because in general all parties do not have access to TTNT.
Even for a party that does have access to TTN1, it runs into the lack of canonical SAC issue.
Finally, the digital signature approach doesn't support coin operations which are fundamental to the cryptoeconomic incentives behind certified messaging and collaboration.

Embodiment Construction
[0027]Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, preferred embodiments of the present invention are described.
[0028]The present invention solves the deficiencies of the prior art by providing without limitation confidential certified communication and dynamic chain-of-trust. Dynamic chain-of-trust allows a party, such as a patient, to forward a certified communication, such as a prescription, to another party, such as a pharmacy, in such a manner that the second party can trust the provenance and content of the forwarded communication without having direct access to the original communication. A dynamic chain-of-trust is also confidential. The present invention utilizes various confidential certified communication and collaboration operations including without limitation, C-sends, C-forwards, C-update, C-drop, C-drop-updates, C-TrueCopy, and C-instantiation as defined herein. “C-send” refers...

A method for providing certified confidential data collaboration between untrusted parties, including creating a changeset proposal, remotely performing a certified operation and passing the changeset proposal to the certified operation, creating a unique changeset reference validating the changeset proposal and creating a state-at-changeset structure extracting a section-state-at-changeset structure from the changeset proposal, performing a cryptographic hash of the state-at-changeset structure and the section-state-at-changeset structure, writing to a local transactional database a changeset fat twin record communicating a changeset reference notification for each fat twin record to the parties, performing a certified operation in a blockchain a certified thin twin smart contract and passing the changeset reference, the cryptographically hashed state-at-changeset structure and the cryptographically hashed section-state-at-changeset structure, validating that a previous certified operation with the same changeset reference does not exist, writing to the blockchain a new thin twin record and performing a proof-of-certified-operation on the thin twin smart contract.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of and claims priority to U.S. patent application Ser. No. 15 / 866,460, entitled “System and Computer Program Product for Certified Confidential Data Collaboration using Blockchains,” filed in the U.S. Patent and Trademark Office on Jan. 10, 2018, having at least one common inventor as the present document and hereby incorporated by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention is generally related to certified confidential data collaboration using blockchains.Discussion of the Background[0003]The bulk of communication, commerce and collaboration requires confidentiality. Confidential collaboration today is plagued by massive inefficiencies, lack of visibility, plausible deniability, data fragmentation, inconsistent data and the like. For example, consider a doctor writing a prescription. The doctor is the source-of-truth for the prescription which is consid...
