thank you . this was good. But some questions - 1. Who comes up with the mathematical puzzle to solve? 2. Or is it hard coded in the blockchain protocol? 3. if yes - is it wired to get more and more complex as the technology improves with decades? 4. Can you give me an example of a mathematical puzzle that is used to solve to give the node the power to confirm a transaction and add it to blockchain? 5. how is the 51% malicious thing will be solved?
@aznee.87982 жыл бұрын
Answer to your last question - it currently can't, but owning 51% of like a block chain is almost impossible. It means you have to have spent 100s of billions of dollars just to have the computing power to change the following block-hashes, and the cost will out weigh the reward. Therefore, if you aren't as rich as Elon Musk, and have the iq of a monkey, it's practically impossible to have 51%

51% attack means um.. if a person/group has control of more than or equal to 51% nodes in the blockchain database, then they have the power to alter the verifications i mean give their own verifications and similarly affect the blockchain

If any transaction is made from A to B, then all nodes will also be able to see this transaction? How? and in what format is this secracy between A and B is stored in all other nodes ledgers?
@akshaydevh4 жыл бұрын
If the transaction has occurred in a bitcoin blockchain, every other node can see the transaction. In fact, any other person can check the transaction using block explorers. However, bitcoin addresses will be 32-34 bit random numbers so nobody can trace the actual owners.

Because transactions is cryptographically signed messages, signed by senders private key. Easy to validate sender pub-adr & priv-sign valid or invalid. transactions are verified by nodes on receive. Unconfirmed transactions, form mempool-merkle tree for next block.
