Compactness

Each hex digit represents 4 bits, making it concise for large binary numbers.

Alignment

Hex aligns with binary computing, aiding data representation and processing.

Standard

Widely used in programming and cryptography for simplicity with binary data.

Length

Ensures consistent string lengths, crucial for Ethereum addresses and hashes.

Conversion

Straightforward mapping to binary facilitates error-free conversions.
