ABOUT DOUBLEZERO

DoubleZero is a decentralized, permissionless protocol that revolutionizes network performance for distributed systems like blockchain. The mission is simple: increase bandwidth and reduce latency.

DoubleZero increases bandwidth by filtering junk data that currently plagues validators and other network operators. DoubleZero reduces latency by connecting these filters with underutilized private fiber links in the form of a mesh network. By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to reach performance levels that are currently impossible.

In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself. We look forward to hearing from you.

If you're eager to learn, grow, and contribute to the mission but worry that you may not have the “right” experience, we still want you to apply. We encourage applications from everyone, regardless of background and life experience. We’re firm believers that a little bit of slope makes up for a lot of y-intercept. Fluency in English is required due to the percentage of English-speaking customers and the nature of our platform, which is available to all Canadians.
