With a first-of-its-kind digital torch lighting ceremony, the 19th Hangzhou Asian Games got underway. Through the Alipay app, more than 100 million digital torchbearers took part in the ceremony, culminating in the lighting a huge lotus flower. Following the ceremony, each digital torchbearer was given a special digital certificate that served as a reminder of the moment the torch was lighted and was kept on the AntChain utilizing distributed technology.
Whale Explorer served as the issuing platform for the digital central torch tower of the Asian Games, and AntChain handled the technical implementation for on-chain confirmation, storage, and issuance. The blockchain was used to store all digital data, and smart contracts gave each collectible a distinct hash value. The distribution of these values to users who bought them in real time ensured their transparency, immutability, and non-duplicability
