## Block Size
The block size is currently recommended to be slightly below 64 KB (minus message header overhead), so that it fits within a single UDP packet. Having a block size smaller than the max. message size reduces complexity when exchanging individual blocks and increases performance for operations such as file search.
Peers must accept a minimum block size of 1 KB.
The target block size (for generating new blocks) is defined via `TargetBlockSize`. If records cannot fit within that target size, they are added into a new block.
Small block sizes ensure that the block will be transferred via blockchain exchange and cached in DHT.
Large blocks may be ignored by clients for size and spam reasons, resulting in decreased discoverability.
