HACD (Hacash Diamond) stands as the world’s first implementation of the HST framework. HACD introduces a unique approach to HST with a total supply of 16,777,216 Base Tokens, issued through a Proof-of-Work (PoW) mechanism.
These tokens are generated via hashing power and on-chain bidding, with a maximum of 58 Base Tokens produced daily. The mining difficulty increases over time, resulting in only approximately 0.6% of the total supply being issued over the past 6 years since its inception.
Each HACD Base Token is uniquely identified by a 6-letter code and a serial number. For instance, the first HACD, produced on May 16, 2019 is labeled the identifier NHMYYM and serial number 1. With a storage capacity of 12.5 KB, each Base Token manages Stack Tokens and stores relevant data, aligning with HST’s foundational requirements. HACD operates on the Hacash blockchain, utilizing an indexer-based system to track token interactions efficiently, eliminating the need for traditional smart contracts.
HACD’s Stack Protocol supports two types of Stack Tokens:
* **Mutable Stack Token:** This type allows the issuance of FT, NFT, or SFT, with the flexibility to modify token quantities. Issuance and minting require HAC (the native currency of Hacash) as a transaction fee, with common issuance methods including auctions and minting. This enables dynamic market applications, such as adjustable in-game currencies or evolving digital assets.
Example: Mutable Stack NFT
* **Immutable Stack Token**: Requiring an upgrade to the Hacash mainnet, this type becomes unalterable once set. It is primarily used for generative art NFTs, such as HACD’s visualized diamonds, with a total supply matching the 16.77 million Base Tokens. These diamonds are created using visualization genes, resulting in 9 distinct shapes, 8 of which are special diamonds with a 3% probability of occurrence, adding unique value to the ecosystem.
Example: Inmutable Stack NFT
HACD demonstrates HST’s potential, allowing users can issue and manage Stack Tokens within HACD and leverage its unified structure to explore innovative applications across various industries.
