In Blockchain, blocks can be identified by the block header hash and the block height.
No, it’s not possible to do so. In case any modification is required, the organization simply has to erase the information from all other blocks too. It is because of no other reason than this, data must be given the extreme care of while using this approach.
Every block in this online ledger basically consists of a hash pointer which acts as a link to the block which is prior to it, transaction data and in fact a stamp of time
Blockchain consists of a list of records. Such records are stored in blocks. These blocks are in turn linked with other blocks and hence constitute a chain called Blockchain.
Data security always matters. Encryption is basically an approach that helps organizations to keep their data secure.cryptography-top blockchain interview questions-edurekaThe encrypted data is encoded or changed up to some extent before it is sent out of a network by the sender and only authorized parties can access that information.In Blockchain, this approach is useful because it simply adds more to the overall security and authenticity of blocks and helps to keep them secure.
Blockchain can be trusted due to so many reasons.
Its compatibility with other business applications due to its open-source nature.
Its security. As it was meant for online transactions, the developers have paid special attention to keeping up the pace when it comes to its security.

Coins are mobile, persistent, commutable, and have limited supply. Besides, they don’t have any functionality beyond acting as money.
Tokens are referred as an asset or utility, that require existing blockchain to operate & function. They require another platform like Omni, Lisk, Waves, Stratis and Ethereum to operate. Tokens are designed in a way that activate features & functionality of an application. For example: Musiccoin is a token designed to give users can access of different features of music platform.
The main difference lies in their structure as coins are considered as separate currency and have their own separate Blockchain. And Tokens reside on the top of Blockchain that functions with decentralized applications.
