Uh Oh: Blockchain May Not Be as Secure as We Thought
Jingyi Wang/Victor Tangermann

In Brief
In an analysis of one million smart contracts, a new analysis tool found that 34,200 had security vulnerabilities. Before we transition to a blockchain-based digital economy, we need to address the flaws in this system.


Blockchain has the potential to transform our world. Experts insist the technology is “bigger than the internet,” but we may want to take a beat before we put everything from our money to our health records on blockchains. According to a new study, the technology isn’t nearly as secure as we thought.

Back in 2009, Bitcoin set the blockchain revolution in motion giving any two parties, anywhere, a way to quickly and securely transfer money.

Some blockchains, most notably Ethereum, take the utility of Bitcoin to the next level by incorporating smart contracts, which automate the process.

For example, say you want to buy 10 ether tokens, but only if the price drops below $600 per token. Smart contracts are set up to execute specific actions when they encounter a specific situation, so you could set one up to buy 10 ether when the price drops.

That’s not all they can do: while smart contracts can be as simple as the above, they can also be far more complicated. You could also set up a smart contract to buy ether if the cost hits below $600 per token, and you have an account balance above $10,000, and it’s a Friday.

Smart contracts are essential for industries outside of finance that want to take advantage of the blockchain technology. For example, if healthcare systems wanted to put medical records on a blockchain, it could use smart contracts to ensure only medical professionals are granted access to them.

While it all sounds good in theory, there is some bad news: a team of computing experts from the National University of Singapore and University College London published a study that details a surprising number of security flaws in smart contracts.
