Thus, our example changes its appearance: now we just ne.
To hang chains of paper clips on our hook object, just like other such simple objects symbolizing block headers. And this nes to done for all objects. It turns out that each header has a common database of transactions within the cryptocurrency system identical to the other headers. Therefore, blockchain is also call a distribut database, when each participant of the array (header) has information about the events that occurr with all other participants of this array.
Let’s try to consider what blockchain is in simple words for dummies using the example
functions of the control system telegram number list of this technology. So what about the control system? It turns out that it has 2 main functions:
distribution between all databases of information about the transactions carri out, attach to each header in the system. (And preferably as quickly as possible);
checking the initial Control System state of the header before executing the transaction. (Now there is something to check against).
Each such check consists of obtaining six confirmations
Correctness by comparing the initial state of the block header (with which the transaction is suppos to be made) with information obtain from the databases of other (six) headers, select randomly.
Why exactly 6 confirmations? Simple mathematical analysis (well, how simple, probability theory) shows that for a successful “emission of duplicates” a potential fraudster would ne to carry out a simulation in such a number of blockchains recent mobile phone number leads that this would require truly monstrous aero leads computing power, the aggregation Control System of which simply does not seem realistic to the creators (and users) of cryptocurrency systems. At the same time, the probability of a “random hit” with exactly 6 independent confirmations is estimat at no more than 0.001%. And this is taking into account the possible probability distribution.
