We are excited to lead Arcium’s $5.5M strategic funding round to launch the first parallelized confidential computing network. Arcium will enable use cases that combine the old network effects of Web2 with the new network effects and capabilities of Web3: liveness, permissionlessness, composability, censorship resistance, verifiability, and, last but not least, ownership.

Without transaction privacy, everything on-chain is public. Users expose their information and metadata. Most users don’t want that - especially institutional ones. Nevertheless, it is by no means certain that transaction privacy will become an essential feature of public blockchains. This research effort discusses regulatory and usage challenges and the most promising approaches and protocols to combat them. It covers their basic ideas and trade-offs and suggests a categorization of the current landscape of transaction privacy.

We're thrilled to share that Greenfield is leading Stroom's $3.5M seed funding round.
