Intro to the Kampela Signing Device | Infosession by Kampela

​In this session we will present Kampela, an open hardware signing device. It is a hardware implementation of Polkadot Vault (previously known as Parity Signer). It is a small card-shaped device (ideally comparable to a credit card form factor, to be carried in a wallet when needed) that accepts data through unidirectional NFC port and shows output on a monochrome electronic paper screen. 

​It has cryptographic strongbox with elliptic curves supported by Substrate — which only stores private keys (after initial import) and performs all signing operations on-chip.

​Kampela is a natural (and long-discussed) extension of Parity Signer to leverage the most out of modern hardware-based crypto chips and drastically reduce Signer’s attack surface: no mobile OS, not extra platform features, no unexpected communication methods or airplane mode to take care of.

​If you are still wondering why we defined it as signing device and not wallet, what are the differences with Polkadot Vault, what are the security considerations of this DIY/DIWO adventure,  or why it has a fish name, come join us to be hands-on all the way down with your self-custodial storage.

This session is intended for everyone whether you are interested in Substrate based world, or you are just a Kampela curious.
