Bitcoin is Not Just a Database in the Rasberry Pi or in the Apple Pie - Bitcoin is systemised Computational Datastructure in the Blockchain which has PoW and timestamp.

You just cannot change anything as you like to add or change aas you wish. It is cryptographically secured because it is the blockchained Database. If you alter one single indexed number, then it will alter the rest of the merkele tree and makes it unsecured.

Therefore, think not that Bitcoin Blockchain is can be altered by any one who likes to do it. It is impossible because it is the bullet proof Blockchain technology with the permanent clock base structure behind it for absolute security.

Are you trying to convince yourself of these things?

OK. More bitcoin uses the blockchain as storage which is a distributed ledger that uses PoW for its security and timestamps for very little.

If any information in a merkle tree is changed then the root node is changed and bitcoin survives off the root node of old blocks being unchangeable as a hash of them with other data is referenced by the next block.


The distributed proof of work algorithm and the decentralised network is what keeps everything secure. It's not exactly that there's one clock that decides everything, there's many! This is what keeps things more secure. The Internet would have to reduced to barely anything to ensure all of these clocks/nodes are disconnected from the network. 

"clock base structure" ?

bitcoin is not a clock

like employment
when people do work. the boss does not look at the clock on the wall to do the accounting of wages and workload performed.. he looks at the sign-in log sheet of employees that turned up to work.

bitcoin is not the clock on the wall, its the employee timesheet on the table which includes the work they performed that day
