I perceive that if one dangerous individual(node) tampered one block of his/her blockchain, the block hash knowledge modified fully completely different.
To illustrate every node has 10 listed blockchain and index4 block has transaction knowledge like [Alice → Bob 10BTC]. Additionally the block has [00000000b78qgifg20b] hash as a sound knowledge(stars with 8 zeros).
Now, one dangerous individual(node) tampered index4 block’s transaction knowledge [Alice → Bob 30BTC] and the hash knowledge modified from [00000000b78qgifg20b] to [f24yoxyn28hk8hohko].
Does this imply new block is created? In that case, new block with [f24yoxyn28hk8hohko] is gonna be distributed to all nodes and added to their blockchain as a brand new mined block?
