Chinese blockchain platform ChainMaker says it has new technology to keep it secure from quantum attacks
- Developers say a digital signature algorithm further secures information transmission between financial institutions, official news agency reports
- Also known as Chang’An Chain, it is China’s first independent blockchain platform and was developed by a state-backed Beijing consortium

Developers of the enterprise blockchain – also known as Chang’An Chain – said the new technology further secures information transmission between financial institutions, making online transactions safer, the news agency reported on Monday.
The system released in January last year is China’s first independent blockchain platform, developed by a state-backed Beijing consortium – the Beijing Academy of Blockchain and Edge Computing.
Its software and hardware were jointly developed with institutions such as Tsinghua University and Beihang University, and tech giants including Tencent and Baidu.
A post-quantum digital signature algorithm has been integrated into the blockchain platform to keep it secure from attacks – even those by quantum computers that can potentially threaten the security of traditional communications, the report said.
A blockchain is a permanent log of transactions. The digital list of records is designed to be difficult to alter without being detected and is stored in blocks, each containing the transaction time and data.
