HTMLCOIN is the native coin and gas that powers the Althash blockchain. It was conceptualized in early 2013 and launched on March 8, 2014 as a Bitcoin clone under the name of HTML and then HTML5 in 2015. In 2017, a new algorithm for the coin was implemented and a coin swap was initiated in November of the same year where the HTMLCOIN name was chosen for the rebrand. HTMLCOIN became a Proof of Work/Proof of Stake cryptocurrency based on the Bitcoin Core algorithm. Enabled through an Account Abstraction Layer, the updated HTMLCOIN environment allowed an account-based VM (Virtual Machine) to function on a Bitcoin UTXO based blockchain, expended with attributes of QTUM and ARK.
