Solana's Block Propagation Problem Was Huge-Here's How They Fixed It | HackerNoon
Briefly

Traditional blockchains face scalability issues as block propagation demands significant bandwidth, especially with a high number of validators. Solana's Turbine addresses this by implementing a multi-layer mechanism that breaks large blocks into smaller chunks, allowing for efficient data dissemination through a peer-to-peer network. Similar to BitTorrent, Turbine uses UDP for fast data transmission and employs random paths for packets, enabling quick accessibility for all nodes. This innovation ensures high throughput and resolves common bandwidth bottlenecks, making Solana more efficient than traditional blockchain systems.
Turbine breaks blocks into smaller chunks and disseminates them through an order of nodes, reducing the load on individual nodes during block propagation.
This high speed of block propagation allows Solana to maintain its high throughput by optimizing data transmission through a UDP network.
