Unlike Bitcoin, which relies on a single longest chain, GhostDAG operates on a blockDAG (Directed Acyclic Graph) of blocks. In high-throughput environments where many blocks are produced simultaneously, this matters. Here’s how it works: Blue vs Red blocks: GhostDAG identifies a k-cluster which is a set of blocks that are densely connected and presumed to be honest. These are called blue blocks. Blocks that fall outside this cluster are red blocks and are not included in the final ledger view. Why this matters: With traditional Nakamoto consensus (like in Bitcoin), high orphan rates reduce security and decentralization. But GhostDAG embraces them. It accounts for all blocks even those created simultaneously and still reaches a secure, deterministic ordering. The result: Kaspa achieves high throughput (currently XX blocks per second, targeting much more) without compromising on decentralization or security. It scales layer-1 performance without relying on second layers or trust assumptions. Next post will unpack: • How GhostDAG ranks blocks • What the k-cluster really is • Why it’s provably robust at scale $kas XXX engagements  **Related Topics** [blockdag](/topic/blockdag) [protocol](/topic/protocol) [blockchain](/topic/blockchain) [breakthrough](/topic/breakthrough) [blocks](/topic/blocks) [kaspa](/topic/kaspa) [coins layer 1](/topic/coins-layer-1) [coins pow](/topic/coins-pow) [Post Link](https://x.com/ashishinsydney/status/1948765957855601101)
