What is Algorand Standard Asset (ASA)?

Algorand Standard Assets (ASAs) are on-chain assets native to the Algorand blockchain protocol. As on-chain assets, ASAs enjoy the same speed and security as Algorand's consensus protocol itself. ASAs can be fungible or non-fungible, representing items as varied as stablecoins, in-game points, or a deed to a house. ASAs must essentially adhere to several parameters determined by Algorand, though they also allow developers some customizability.
