The algorithm maintains a running "best distance" that starts at infinity. As it walks the tree, it checks each visited point and updates the best distance if it finds something closer. Before recursing into a child node, it checks whether the closest possible point in that child's bounding box is farther than the current best. If so, the entire subtree gets pruned.
Okay, let’s start from the top. CRDT stands for “Conflict-free Replicated Data Type”. That’s a long acronym, but the concept isn’t too complicated. It’s a kind of data structure that can be stored on different computers (peers). Each peer can update its own state instantly, without a network request to check with other peers. Peers may have different states at different points in time, but are guaranteed to eventually converge on a single agreed-upon state. That makes CRDTs great for building rich collaborative apps, like Google Docs and Figma — without requiring a central server to sync changes.

Led by longtime investor and entrepreneur Chris Dixon, a16z crypto launched its first $300 million fund in 2018, the year after a blockchain craze sent Bitcoin prices soaring to $20,000. Each subsequent fund has been larger than the last, culminating in a monster $4.5 billion vehicle in 2022 out of which the firm continues to invest. While the latest fund will be less than half that amount, one of the sources said that a16z crypto is planning a shorter fundraising cycle to take advantage of how rapidly trends in crypto can shift. The previous funds were all raised within one or two years of each other. (A16z crypto chief marketing officer Kim Milosevich declined to comment.)
