SpaceComputer is a satellite-based confidential-computing and cryptographic-security infrastructure project co-founded by Daniel Bar and Filip Rezabek. SpaceComputer's Twitter Score is 37 out of 1000 as of August 2026, ranking #25,583 (top 10%) among 483,944 tracked accounts.
SpaceComputer was co-founded by Daniel Bar, who serves as CEO, and Filip Rezabek, who serves as CTO. The project builds what it calls Space Fabric, a secure-compute architecture designed to run confidential workloads on satellites in orbit. The Space Fabric research paper is authored by Rezabek alongside Dahlia Malkhi and Amir Yahalom. Tropic Square has announced that its open and auditable TROPIC01 secure element is being integrated into Space Fabric hardware for orbital compute.
SpaceComputer raised a pre-seed financing round led by Primitive Ventures, followed by a $10 million seed round co-led by Maven 11 and Lattice. Additional backers include Superscrypt, Ethereal Ventures, Arbitrum Foundation, Nascent, Hash3, Amber Group, Bitscale Capital, Bodhi Ventures, Offchain Labs, Moonrock Capital, Chorus One, imToken Ventures, Encode Club, Wise3 Ventures, Symbolic Capital, Public Works, and others.
SpaceComputer's roadmap describes two complementary layers: Celestial Chain, an in-orbit blockchain that uses satellites as tamper-resistant compute nodes, and Uncelestial Chain, an Earth-based L2 that settles to Celestial Chain. The project selected EigenCloud's EigenDA as the data-availability layer for its L2 stack. As of April 2026, SpaceComputer was participating in three active orbital missions with the Aptos network, had its own satellite launch planned for Q4 2026, and had two further launches scheduled through Q4 2027. Per Payload, a demonstration of Space Fabric on a Spacemanic satellite was planned for 2027. SpaceComputer is also affiliated with the UCSB Center for Distributed Systems and Security. The account has 4,372 followers as of August 2026 and has published 1,185 posts, and has been mentioned by 55 accounts a total of 133 times.
