Blockchain security not all that watertight

SMU Associate Professor of Law Kelvin Low shared his views about blockchain technology and the common misrepresentation about its level of security. He noted that a widely held view is that blockchain technology is “impervious to fraud” but that cannot be further than the truth. Associate Prof Low highlighted that bitcoin and its ilk are often referred to as cryptocurrencies because of the cryptographic protocols that underlie the blockchain technology. He added that, “It is important to realise that the cryptography simply entails the use of a public key and private key cryptographic system. For bitcoin, this means that your bitcoin is secure only if your private key is secure. If you lose your private key, you lose access to your bitcoins. If someone acquires knowledge of your private key, that person acquires access to your bitcoins.”
