Professionals assess cryptocurrency, NFTs, stablecoins and blockchain

Its well reported that big tech are looking seriously at Web 3 and investing in blockchain tech. Whilst Web 3 is a somewhat vague term, the general view seems to be that it is, philosophically at least, a return to some of the decentralisation that marked Web 1, with added benefits.

Whilst Web 2 is now characterised as a huge centralisation project, with nearly everything collected into platforms, one of the key drivers behind Web 3 is the heady mix of blockchain technology and its role in decentralised digital currency cryptocurrencies and other technologies such as non-fungible tokens (NFTs), that promise to create monetary value in abstract items such as art.

What do the experts think about these technologies? It depends on who you ask, what their vested interest may be and even political persuasion. When the UK government, as announced by Chancellor Rishi Sunak, declared an ambition to make the UK a global cryptoasset hub BCS asked its professional membership and other IT experts for their view.

The feedback makes for stark reading: 58% do not support the Treasurys plan to make Britain a global centre for cryptoasset technology and investment, including stablecoins and NFTs. Just 29% said working technologists should get behind the crypto project, with the remaining 13% neutral.

A large majority (77%) were not confident that another key part of the plan – recognising and regulating stablecoins – would ensure financial stability and provide wider consumer payment choice.

The result on stablecoins is particularly telling, as they are a form of cryptocurrency designed to be more settled than the widely fluctuating value of crypto currencies. The idea is that by pegging stablecoins to another asset or currency – such as sterling the financial risk of using them is reduced.

However, according to this survey, IT professionals dont see the benefit, with 69% telling BCS that the public could not have the same level of confidence in UK regulated stablecoins as in commercial bank money. A similar proportion (63%) said the Bank of England should not guarantee stablecoins to cover possible risks.

The view of NFTs was even clearer: only 14% of tech experts surveyed said the Chancellor was right to ask the Royal Mint to launch an NFT this summer. Indeed, NFTs are an even more contentious concept then cryptocurrencies, so it was unsurprising that 68% of tech specialists said it was wrong for the Royal Mint to launch its own NFT this summer.

Only 10% were optimistic about the potential of NFTs to do good for society, although 41% said they were positive about the potential of blockchain technology to benefit people.

Concerns

What are the issues? Energy consumption and impact on climate change ranked as the biggest concern IT experts had about the wider adoption of crypto; 23% selected this as top priority for government to consider before wider rollout of the technology. This was closely followed by the prevalence of money laundering and ensuring the safety of crypto wallets and exchanges (both 15%), then regulation and educating the public (both 14%).

Energy consumption is a matter that cannot be ignored. It was analysed recently by a BCS writer, who commented that blockchain implementations that use the original proof-of-work (that is most of them) are a climate-change disaster and should be stopped. And the numbers are interesting.

Another issue raised by tech experts in the comments that supported the poll was the view that cryptocurrencies and NFTs were reminiscent of pyramid or Ponzi schemes and thus to be avoided by the public and policy makers. Regular Twitter followers of IBMs Grady Booch, the creator of unified modelling language, are often treated to ironic thoughts and prayers for crypto schemes especially over recent weeks as so many of their values have plummeted. BCS recently interviewed him.

The other main issue is that of trust. Ironically, whilst blockchain is seen as trust mechanism, the comments on this BCS survey reveal that IT professionals clearly think that more education and a robust regulatory framework around these technologies is needed to create genuine trust and confidence.

And what of the wider societal context? On the NFT, Dr Bill Mitchell OBE, Director of Policy at BCS, The Chartered Institute for IT said: In particular the coming launch of the Royal Mints NFT needs to avoid striking a bum note at a time of spiralling cost of living and industrial action.

Taking the temperature

So, IT professionals polled by BCS have a clear view. And their views largely chime with other respected thinkers in computing and IT.

Whilst Sir Tim Berners-Lee has taken a slightly mixed approach he made an NFT of the original source code for the world wide web that garnered $5.4 million – his current brainchild to help individuals take control of their own data called Solid – is not based on blockchain, but existing web tools and open specifications. An interesting example of one of the oft-cited criticisms of blockchain – that it solves problems that can already be solved by other means, and in a far less earth-friendly way.

Security guru Bruce Schneier and other experts wrote to US Congress in June 2022 with an unequivocal view – saying that cryptocurrencies are a complete and total disaster. Interestingly he comments on this: The problem is that they (cryptocurrencies and blockchains) dont do anything their proponents claim they do. In some very important ways, theyre not secure. They dont replace trust with code; in fact, in many ways they are far less trustworthy than non-blockchain systems.

Theyre not decentralised, and their inevitable centralisation is harmful because its largely emergent and ill-defined. They still have trusted intermediaries, often with more power and less oversight than non-blockchain systems. They still require governance. They still require regulation. The problem with blockchain is that its not an improvement to any systemand often makes things worse.

On the question of blockchain becoming a trust mechanism, respected programming blogger Stephen Diehl points out that trusted third parties are an inevitable requirement in any system, and no technology offers solutions to that issue. In a practical sense he points to the use of a real database like PostgreSQL as always being a better solution.
