Grailstone is an interactive 3D generative artwork that captures the essence of natural crystals while intertwining with the Bitcoin blockchain. Each piece evolves through 64 unique stages over 8 weeks of human time (8192 blocks), its transformation shaped by real-time blockchain data. No two Grailstones are alike - transaction patterns, block timestamps, and even the rarity of the inscribed satoshi influence their growth, making each final form truly unpredictable. Merging nature’s intricacy with digital permanence, Grailstone is both a tribute to the Earth’s hidden sculptures and a testament to the ever-unfolding blockchain.
