The internet is in bad shape right now. After nearly two decades of tech innovation and mass participation on the world wide web, there are now obvious dangers when valuable information is stored online. After almost two decades of innovation and growth, the cracks are beginning to show, and it is becoming increasingly clear that storing information online comes with severe risks. The internet has seen hackers and other malicious actors profiteering from the sale or fraudulent use of user data. From Yahoo to Equifax, major players online are vulnerable to hackers on a near-weekly basis.
It is not just emails and financial data being siphoned off – social media giant Facebook, home to almost a quarter of the world’s personal information, recently made headlines with the Cambridge Analytica scandal: a breach that saw the data of 87 million users misappropriated in order to micro-target users in an attempt to influence their political views. The usual surface-level reactions of outrage and cries to boycott did not do much to help – despite its popularity in the media, the #DeleteFacebook campaign was a failure. History is bound to repeat itself if a viable solution does not appear – going analogue in the digital era is not feasible.
The solution has to lie in better technology. As people continue to digitise every byte of information they produce, there needs to be a more secure infrastructure that allows individuals to use the internet without running the risk of having their data compromised.
The Blockchain Offering
There is a significant buzz around blockchain as a means to improve internet security. The hype is unsurprising – a blockchain is a decentralised ledger with censorship resistance and immutability baked-in at the protocol layer. It was introduced almost a decade ago as the mechanism that secures bitcoin and has since captivated startups and established companies.
Some blockchains support smart contracts, which allow for the creation of fully decentralised applications atop the network. Ethereum is the leading security actor on the blockchain and has been adopted by thousands of teams in their efforts to create secure platforms. With its popular ERC-20 token model an established industry standard, companies working with Ethereum are on the front line of security in the digital space.
For all its strengths regarding internet security and transferability, blockchains are currently incapable of storing large amounts of data. As while tokenisation opens up interesting ways to timestamp and guarantee the provenance of the data, blockchains are incapable of providing privacy (given their public nature). There are fortunately better methods of storage that can work in conjunction with a distributed ledger. For example, instead of uploading company records or scanning documents to the blockchain, an ‘off-chain’ solution would be better suited to preserving these records.
As such, sensitive information can stay secure with its provenance assured, while also remaining transferable through the use of a utility token.
Building a Digital-First Future
Revaluating security in a digital age, where citizens are ‘plugged in’ through internet-connected PCs and smartphones in both a personal and professional capacity is essential for businesses and governments. If recent hacking and data breaches are anything to go by, then businesses need to stop using dated infrastructures prone to compromise, and start considering alternative technologies. Blockchain-based systems are shining a bright light on a dark problem. When existing centralised hierarchies are dissolved and by embracing decentralisation, internet users will be able to securely and privately store their data without fear.
