HTMLCOIN is the base coin and gas that powers the Althash hybrid blockchain. The HTMLCOIN environment describes itself as a decentralized Proof-of-Work/Proof-of-Stake hybrid blockchain with fast and secure transactions. While it uses the hashing function and the base layer of Bitcoin to create a secure blockchain and irreversible address mapping, it integrates Ethereum EVM, aka HVM, to run multiple Dapps/programs as a worldwide decentralized, failsafe and secure computer system, additionally making the creation of Ethereum based Smart Contracts possible. The Althash blockchain allows one to effectively build ecosystems on its platform and to power them through HTMLCOIN, meaning Althash/HTMLCOIN can have its own ecosystem of various tokens from HRC20 (ERC20) simple fungible tokens, HRC721 (ERC721), used for instance with NFTs, up to dedicated complex programs allowing the minting of adjustable new tokens, which will be instantly rolled out on the mainnet according to specific needs.
