IS BITCOIN A TRIPLE ENTRY SYSTEM?

Yes, so back to crypto, or at least financial cryptography.
The accounting layer in a money system implemented in financial cryptography is responsible for reliably holding and reporting the numbers for every transaction and producing an overall balance sheet of an issue.
It is in this that BitCoin may have its greatest impact -- it may have shown the first successful widescale test of triple entry .
Triple entry is a simple idea, albeit revolutionary to accounting. A triple entry transaction is a 3 party one, in which Alice pays Bob and Ivan intermediates. Each holds the transaction, making for triple copies.
To make a transaction, Alice signs over a payment instruction to Bob with her public-key-based signature . Ivan the issuer then packages the payment request into a receipt, and that receipt becomes the transaction.
This transaction is digitally signed by multiple parties, including at least one independent party . It then becomes a powerful evidence of the transaction .
The final receipt *is the entry*. Then, the *collection of signed receipts* becomes the accounts, in accounting terms. Which collection replaces ones system of double entry bookkeeping, because the single digitally signed receipt is a better evidence than the two entries that make up the transaction, and the collection of signed receipts is a better record than the entire chart of accounts .
A slight diversion to classical bookkeeping, as replacing double entry bookkeeping is a revolutionary idea. Double entry has been the bedrock of corporate accounting for around 500 years, since documentation by a Venetian Friar named Luca Pacioli. The reason is important, very important, and may resonate with cryptographers, so let's digress to there.
Double entry achieves the remarkable trick of separating out mishaps from frauds. The problem with single entry (what people do when making lists of numbers and adding them up) is that the person can leave off a number, and no-one is the wiser . We can't show the person as either a bad bookkeeper or as a fraudulent bookkeeper. This achilles heel of primitive accounting meant that the bookkeeping limited the business to the size with which it could maintain honest bookkeepers.
Where, honest bookkeepers equals family members. All others, typically, stole the boss's money. (Family members did too, but at least for the good of the family.) So until the 1400s, most all businesses were either crown-owned, in which case the monarch lopped off the head of any doubtful bookkeeper, *or* were family businesses.
The widespread adoption of double-entry through the Italian trading ports led to the growth of business beyond the limits of family. Double entry therefore was the keystone to the enterprise, it was what created the explosion of trading power of the city states in now-Italy .
Back to triple entry. The digitally signed receipt dominates the two entries of double entry because it is exportable, independently verifiable, and far easier for computers to work with. Double entry requires a single site to verify presence and preserve resiliance, the signed receipt does not.
There is only one area where a signed receipt falls short of complete evidence and that is when a digital piece of evidence can be lost. For this reason, all three of Alice, Bob and Ivan keep hold of a copy. All three combined have the incentive to preserve it; the three will police each other.
Back to BitCoin. BitCoin achieves the issuer part by creating a distributed and published database over clients that conspire to record the transactions reliably. The idea of publishing the repository to make it honest was initially explored in Todd Boyle's netledger design.
We each independently converged on the concept of triple entry. I believe that is because it is the optimal way to make digital value work on the net; even when Nakomoto set such hard requirements as no centralised issuer, he still seems to have ended up at the same point: Alice, Bob and something I'll call Ivan-Borg holding single, replicated copies of the cryptographically sealed transaction.
With that foundation, we can trade.

...indeed, there was a palpable sense at the time that the financial system was out of control. They were looking at this thing with worried eyes.
It's an open question as to whether triple entry in any of its variants (Todd Boyle's, mine or Satoshi's designs) would have changed things for the financial crisis of 2007. I think the answer is; it was way too late to effect it. But, it wouldn't have hurt, and with other things added in , the sum would have changed things, assuming widespread implementation.
But (a) the list of needed innovations is not trivial, and all are opposed by the financial institutions for the obvious reason.
Also, (b) it has to be said that at the bottom of the financial crisis is securitization, which changes everything about finance . And I do mean everything. Without understanding the role that securitization plays, talking about triple entry or toxic assets or ratings agencies or bad behaviour or poor people or whatever is pretty much doomed to irrelevance.
Which is how they like it!

Through the use of cryptographic proof and decentralized networks Bitcoin minimizes and replaces these trust costs. With the available technology, there are fundamental trade-offs between scale and decentralization. If the system is too costly people will be forced to trust third parties rather than independently enforcing the system’s rules. If the Bitcoin blockchain’s resource usage, relative to the available technology, is too great, Bitcoin loses its competitive advantages compared to legacy systems because validation will be too costly (pricing out many users), forcing trust back into the system. If capacity is too low and our methods of transacting too inefficient, access to the chain for dispute resolution will be too costly, again pushing trust back into the system.'bitcoin compare график monero Mobile walletstoken bitcoin

Work was contributed on a part-time basis, whenever volunteers found time; only 250 contributors were full time employees of Mozilla.

If you have a secure ledger, the process to leverage it into a digital payment system is straightforward. For example, if Alice sends Bob $100 by PayPal, then PayPal debits $100 from Alice's account and credits $100 to Bob's account. This is also roughly what happens in traditional banking, although the absence of a single ledger shared between banks complicates things.эмиссия ethereum ethereum сайт
