Partners

Convinced that blockchain is the ideal tool for strengthening trust between partners and making exchanges more reliable thanks to increased control and native transparency, the creators of CONTROLH SAS have decided to create a space dedicated to sharing and showcasing applications that use Tezos as a certification tool.

Owner of a very high-speed dark fibre optic network (400G). Specialist in virtualisation and hyperconvergence. Owner of a sovereign private cloud hosted in several TIER3 data centres in France, 121 SAS was the natural choice for hosting You Checkinn.

Tezos is a Franco-Swiss blockchain focused on developing smart contracts around the cryptocurrency tez (ꜩ, XTZ).

The protocol's algorithm is a long-chain proof-of-stake consensus principle, which makes it particularly energy-efficient compared with other blockchains.

Its modular design allows it to evolve through on-chain governance. This eliminates the risk of a fork and guarantees the continuity of its governance.
