Singapore government to open source contact-tracing protocol


Singapore’s Government Technology Agency (GovTech) is contributing the source codes of the protocol that powers the TraceTogther contact-tracing app to the open source community to help stem the Covid-19 coronavirus pandemic. Launched on 20 March 2020, TraceTogether works by exchanging short-distance Bluetooth signals between phones to detect other participating users in close proximity using the BlueTrace protocol developed by GovTech.

The development team behind the protocol said in its manifesto that mobile apps and wearable devices that deploy the BlueTrace protocol will be able to blend decentralised and centralised models of contact tracing.
