Blockchains are supposed to be decentralized, but there are threats to that ideal, such as the 51% attack.
Many smaller blockchains are at risk of a 51% attack because there are not enough miners to secure the network.
Zcash is working on a long-term solution to prevent a 51% attack by moving to a proof-of-stake system.
