Accenture Patents a Blockchain-Editing Tool (techweekeurope.co.uk)

A blockchain "produces a permanent ledger of transactions with which no one can tamper," reports TechWeekEurope. "Until now." Slashdot reader Mickeycaskill quotes their report: One of the core principles of Blockchain technology has potentially been undermined by the creation of an editing tool. The company responsible however, Accenture, says edits would only be carried out "under extraordinary circumstances to resolve human errors, accommodate legal and regulatory requirements, and address mischief and other issues, while preserving key cryptographic features..."

Accenture's move to create an editing system will no doubt be viewed by some technology observers as a betrayal of what blockchain technology is all about. But the company insisted it is needed, especially in the financial services industry... "The prototype represents a significant breakthrough for enterprise uses of blockchain technology particularly in banking, insurance and capital markets," said Accenture.

They're envisioning "permissioned" blockchain systems, "managed by designated administrators under agreed governance rules," while acknowledging that cyptocurrency remains a different environment where "immutable" record-keeping would still be essential.

    It's interesting, but some of the earliest accounting software I used, which was COBOL-based, didn't allow you to change any ledger once a month was posted and closed. I suppose it was possible to go into the actual database and directly alter records, but the underlying concept was that once a fiscal period was complete, it was inviolate, and the only way you could alter any closed ledger was to post adjusting entries in this period. This could be rather ugly, so you tried really hard not to do any major mistakes. Even end of the year adjusting entries were posted in the next fiscal year.

    Since then I've seen a number of accounting systems that allow all sorts of monkeying around, including posting adjusting entries for a fiscal year within that fiscal year, even though you may be a couple of months into the current fiscal year.

    The reality with financial transactions is some decisions are actually reversed or rolled back. What do you do when your ledger says a transaction occurred that actually didn't occur? I am not sure editing is right solution, but neither is simply putting in a second transaction crediting the money back as now you have 2 transactions that didn't occur in your ledger.

    Typically there is an approval stage in accounting where a transaction can be reviewed and corrected before being posted. Once it has been approved (posted), it may be not be edited. Any adjustments must be made by creating a new transaction. If you have transaction xyz, and you later decide it is in error, you enter another transaction, labeled "reversal of transaction xyz" for the opposite values (inventory adjustment, credit, debit, etc.) Modern systems can even link the adjustment to the original transaction for clarity.

    You are thinking only of bitcoin type scenarios, blockchains have been proposed as solutions for recording financial information for businesses, in those scenarios it most definitely is possible for the transaction to have been recorded yet not have occurred.

    If there is a need for transactions to be atomic, perhaps multiple signatures with expiration dates would be useful. One to "pre-sign" the transaction, and if that transaction isn't cancelled (perhaps with a nonce that is stored as a hash), after "x" amount of time, the transaction becomes permanent. Or, a signature to start a transaction, another to end it. One can use blockchain technology in a lot of ways, and allowing people to "un-sign" something is just asking for trouble.

    Dude, Andersen actually sued Andersen Consulting to stop using the valuable Andersen name. AC lost the suit and were forced to change their name or pay licensing fees. In the end, this was a blessing in disguise, but the order of events was clear and preceded Enron by at least a year.

    You NEVER need to edit. You only need to make a referenced notation and cancel in a write-only fashion. Doing it this way instead accomplishes exactly the same effect but leaves a permanent, unalterable audit trail. Yes, you may make mistakes but that's the point of notation/cancellation.

    To be accurate Andersen Consulting split off from Arthur Andersen and then became Accenture. Arthur Andersen was the accounting firm that closed shop because of their malfeasance with Enron. The thing was that the partners at Andersen Consulting started making tons of money that the Arthur Andersen partners were not. So Arthur Andersen added consulting to their business services and that is when they got into trouble.

    Thats it. If a system is build to permit abuse, it will be abused. If they want to make a "blockchain" that can be "edited", it is not a blockchain, but abuses the blockchain name for fraudulent uses.

    If a record in a blockchain is wrong, just add a clearly marked correction record at the end, and that's it. No need to "edit" a blockchain, and the error and its corrections are visible and can be accounted for.

    I'm not really knowledgeable in the subject, but I wonder if it's even possible at all. Isn't a blockchain exactly there to not be tampered with? Isn't it a distributed system? So "editing" a former block would require you to "edit" it in all distributed systems, changing the hash, and would require all following blocks to be re-edited and re-hashed as well.

    Yes, you're right. That's what Accenture is proposing. They can do this since it is a "private" blockchain and they control all copies. After an edit, they'll need to recompute everything and they can do this since they own all copies.
    Kind of defeats the purpose of the blockchain.
