  • Every block on a blockchain has its own unique identity. The hash value is used to create a unique identifier. This means that no two blocks will have the same identification.
  • The block height and block header hash are used to identify blocks.
  • A cryptographic hash, or digital signature, is used to identify a block. The block header is hashed twice with the SHA256 method to get this.
  • A container data structure is referred to as a block. A block in the Bitcoin ecosystem typically comprises more than 500 transactions. The average block size appears to be 1MB (source). A block in Bitcoin Cash (a hard split from the Bitcoin network) can be up to 8MB in size. This increases the number of transactions executed per second.
