The BLOCKS collection is built on top of the BTC block data with onchain 3D bitfeed representations, inscribed on block-matching uncommon sats, and created with parent-child provenance. BLOCKS•OF•BITCOIN shall be used for growing the BLOCKS ecosystem into 3D worlds with digital assets. A genesis BLOCKS inscription (Gen-0) must have a valid Bitmap as a parent inscription. All BLOCKS inscriptions must be inscribed on their block-matching uncommon sats. For example, this 839020 genesis BLOCKS inscription was inscribed on the Alpha Uncommon sat from the BTC blockHeight 839020 and is a child inscription of 839020.bitmap. All future generations of BLOCKS (1st, 2nd, 3rd generation, etc.) must have valid BLOCKS as parent inscriptions. BLOCKS after the 4th halving block (blockHeight >= 840000) are shown as runic purple blocks because of the native rune data in TXs. BTC block 6929999 will be the maximum blockHeight that can be inscribed for a valid BLOCKS inscription.
