The future is accelerating fast. Digital transformation is changing our lives, work and business. While other sectors are evolving, financial markets are slow, fragmented and siloed. What the world needs is a future-facing financial system that can not only cope with this rapid pace of change, but also shape it. At Fnality, we have been speaking and listening to the real users of today’s financial systems. From businesses to banks, there is a clear, collective ambition. They all need a simpler, faster, safer and more resilient system; one that can move and settle money quickly and efficiently, with minimised risk and greater transparency. To make this a reality, we are bringing together a community of passionate people, institutions and partners who have the right mindset with market & technical knowhow. By blending their expertise, creativity and compliance, we have the power to enable a decentralised, distributed financial market infrastructure. Our multidisciplinary team of leaders, innovators and collaborators work in Agile iterations and constantly adapt to new ideas, technologies and challenges. Together, we are creating a network of distributed Financial Market Infrastructures (dFMIs); a collection of next generation payment systems enabling on chain wholesale exchange of value in central bank money. We are passionate about the possibilities this innovation presents. Together we can enable businesses to focus on their future growth, without worrying about the inefficient processes of the past. The future looks even brighter; further interoperability with other DLT systems to support the rapid growth of tokenised markets means even greater benefits in the years to come. By assembling the brightest minds, leveraging the right technology and aligning with the strongest partners, we’re well on our way to achieving our goals. Our journey will not end there though, because we are committed to continual improvement. Iteration and evolution are in our DNA.

The Convex Foundation builds and maintains Convex, a lattice technology platform for the Internet of Value. We provide fast, scalable and open technology. Build your digital assets, DeFi, NFTs and powerful dApps enabled by realtime, decentralised, programmable economic systems at Internet scale. Lattice technology is a new category of decentralised programmable economic systems that embody the Next Generation Internet.

The combined economic staking scheme is called "Convergent Proof of Stake" (CPoS). We envision a system that enables value exchange while solving the problems of traditional approaches - a network of economic agents that serves the needs of the digital economy. We designed Convex from the ground up to provide the following properties: Global - a single, global network where everyone can transact with everyone else. Open - a decentralised, technology independent system where anyone can participate without asking for permission. Automated - able to support atomic, end-to-end transactions reliably executed trusted smart contracts. Secure - protecting against all types of security threats to users digital assets and transactions. Extensible - capable of supporting unlimited innovation in the types of assets and applications created. Fast - quick enough to confirm economic transaction in seconds, meeting the demands of consumer applications. Cheap - inexpensive to utilise, nobody is excluded by high costs.
