MULTI, 2023—2024
In 2021, the original cryptocurrency was hitting major milestones in mainstream acceptance: Nayib made Bitcoin legal tender in El Salvador. In 2022, Gunna went to the Met wearing a diamond encrusted Ledger crypto wallet. Cash App made Bitcoin a currency users could auto invest in. The following year, BlackRock, the world’s largest asset manager, filed for a spot Bitcoin ETF.
Along with adoption, security protocols around users’ assets became increasingly important.
When Eli Rousso reached out in 2022, he had a solution he was exploring called multi-party computation (MPC). Basically, instead of traditional cold wallets, where the assets are locked with a single key, MPC divides the key into multiple parts (either devices or other users) that speak to each other with math magic to access the funds. With MPC, at least two parts have to agree to unlock the wallet, with no single part holding the entire key.
With no single point of failure, it is a security protocol that makes securing assets both easier to use and harder to steal.
Eli’s company, Multi, was building a unique NFC-powered authenticator as a hardware component to the digital wallet, called Multi Key.
I designed the logo, and worked with Maxime le Grelle to explore the industrial design of Multi’s hardware ecosystem.
