How to use the blockchain properly?

Since 2015, banks, regulators, tech giants and startups all over the world have raised billions of dollars to explore the blockchain.

But the only really successful, scaleable use of the blockchain remains cryptocurrencies like Bitcoin. Bitcoins currently trade at almost AU$4,000, with a total market cap of A$61.4 billion.

The Data61 reports describe some of the possible opportunities for the blockchain in Australia, including monitoring the outbreak of pests or animal and plant diseases, border surveillance, tracking intellectual property, and identity systems that provide greater certainty over entitlements, benefits, and tax obligations. The reports also identify some of the risks.
The risks include both business and technical risks. For example, public ledgers do not afford privacy and blockchains generally are not suitable for storing large volumes of high speed data. Bitcoin’s blockchain has been suffering from this very problem for more than a year.

Data61’s Smart Contracts Report lists some contenders, but first we need to manage the risk of fraud, breach of privacy, and blockchain bloat. Once these risks have been reduced to nil or negligible, the real work can resume.
