After the Monero hard fork on Nov. 30th, there are few changes and upgrades done. The new upgrade introduced the Proof-of-Work algorithm, RandomX which uses random code execution together with memory-focused techniques to be resistant to application-specific integrated circuits (ASIC) — devices optimized for professional mining operations.
Also, the long payment id has been removed. The exchanges have made the
integrated XMR address mandatory.
For the users who do not know
what is an Integrated address, I am briefing it for them -
The integrated address is an address with an embedded payment id. Payment ID in a transaction will be encrypted with a shared secret (one-time random key known only to the sender and recipient). Only the recipient will be able to match the transaction against payment ID.
The integrated address does not contain an extra id like the standard address where it was using the 32 bytes payment id along with the address.
The standard public address is made of:
network byte 18 + public spend key + public view key + checksum
The integrated public address is made of:
network byte 19 + public spend key + public view key + 64-bit payment ID + checksum
Now all the users should use integrated Monero addresses as the exchanges made the use of integrated addresses mandatory. There is no need for a payment id for the XMR address like before.
