# Why QMS Matters When we think of the impact of quantum computing on blockchains, we first think of security. Elliptic-curve-based signatures could break, allowing funds to be stolen. Classical zero-knowledge proofs could be forged, compromising any protocol that relies on them. And even if blockchains migrate to PQ protocols in time, there is still the issue of forgotten accounts not migrating, getting hacked, and the market flooding with stolen tokens.\ But the impact goes beyond that. PQ-secure protocols are slower and result in significantly larger signatures, which will impact the usability and increase the cost of blockchains. Sub-second block times that are now common for proof-of-stake (PoS) chains will not be possible with PQ validator signatures, eliminating PoS's main speed advantage over PoW.\ And while most of the crypto space is struggling with the threats of quantum computing, the potential is being overlooked: an improvement in computing does not only serve malicious parties, but can also be harnessed to improve the performance and security of blockchains. With this in mind, QMS is built from the ground up for a quantum world. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
