Singapore has used blockchain technology to develop a global standard for verifying COVID-19 test results to speed up clearing local and foreign immigration checkpoints when travelling.

• The city state's Government Technology Agency (GovTech) and Ministry of Health (MOH) has developed a set of digital standards used to issue COVID-19 test results, known as HealthCerts.
• HealthCerts uses blockchain technology to issue trustworthy documents that can be verified independently in an open-source framework, news network CNA reports.
• The test results will be available on the government's digital identity mobile app SingPass.
• Only the individuals' hash - or digital finger print - will be published to the blockchain upon issuance to keep data private, claims the Smart Nation and Digital Government Group (SNDGG).
• The Singaporean government will also look into also using HealthCerts for vaccine certificates.
