About our name

Chasqui /cha:s-kee/ -n (-s) messenger.

In the ancient Inca empire in Peru, chasquis were messengers who delivered coded messages throughout the land. Information was recorded in a quipu, an encoding system using knotted strings to represent different things based on the kind, color and number of strings. Just as with AS4 messages sent using our gateway, one chasqui’s ‘payload’ could also consist of a variety of ‘attachments’ besides the securely coded content. A chasqui could also transmit a verbal message or small items, or a combination of these.
The messenger would run along purpose built roads until he reached a relay station where he could hand his message to a rested chasqui who would continue the delivery. You could say that this system of  was one of the first secure multi-hop messaging solutions!
