Snowblossom

In general cryptocurrencies operate with a single sequential blockchain. Validation can only be done with a full understanding of the state of the coin (especially the UTXO set) and sequentially. This mostly limits any cryptocurrency to a small enough set of data to fit on one computer and the transactions rate low enough to be processed by one computer. Even if you tried to use multiple computers, the sequential nature of the blockchain makes the task of validation un-paralellizable.

Snowblossom Braid is an upgrade to make a set of interrelated sequential blockchains such that the work can be fragmented to be processed by multiple computers. This will allow for a much higher transaction rate at the cost of some overhead. This is commonly called sharding.
