Decentralized finance needs alternatives to blockchain

One of the laziest and most frustrating criticisms of digital currencies — particularly Bitcoin (BTC) — is when pundits liken it to a pyramid scheme dependent on the “greater fool” joining to make a quick buck. While some people do indeed purchase digital assets purely for speculative purposes, it’s unfair to ignore many of the great services and achievements that are being made by developers in areas such as remittances, logistics, financial inclusion and intellectual property.

A fairer criticism of blockchains is that, for all proponents say about decentralization, blockchains are still dependent on miners or other powerful players that control their networks. Whether it be factories filled with servers for proof-of-work (PoW), pools of PoW miners, large pools of tokens for proof-of-stake (PoS), or the fact that at times, more than 50% of transactions that run on the Ethereum network run through the Infura API, there’s no ignoring these massive centralized points of failure.

Granted, the design of popular PoW and PoS blockchains has been incentivized to ensure bad actors are punished, yet it remains to be seen how they will operate when the value of digital assets operating on certain blockchains exceeds the value of the underlying ledger’s native coin.

Imagine, for instance, if a popular stablecoin grew so large that its total value exceeded that of the native coin of the underlying blockchain it operated on. Essentially, it would create an inverse pyramid whereby the holders of the native token could control the transactions of the said stablecoin. Given the concentration of many crypto assets among “whales” who have a vested interest in their blockchain’s native token (and price), this could become a very real problem.

In Ethereum, as a PoS ledger, miners’ stakes are in Ether (ETH). Should Tether (USDT) or USD Coin (USDC) become larger than Ether in market value, they could theoretically pull off a double-spend in those respective digital currencies, lose their Ether stake, and still profit more from the double-spend. Although it still remains hypothetical, it’s by no means unimaginable.

This then poses a question regarding how we should rethink distributed ledger technology (DLT) architecture and the role mining or staking assets should play.

Tether now boasts a market capitalization of over $80 billion, Circle just under $30 billion, while the Ethereum blockchain it’s programmed on has a market capitalization of Ether over $220 billion — not that far, given how quickly things can change in crypto.

This problem might seem theoretical and far off from being a potential issue; however, the rapid growth of cryptocurrencies as an asset class over the last decade should make people pause to consider what could happen if stablecoins enter the mainstream. Although DLT remains a very young industry, the last 14 years have given us their fair share of unexpected surprises, unintended consequences and shocks that, in hindsight, seemed obvious.

Developers might consider whether now is the time to rethink the architecture underpinning digital assets. Dependency on centralized miners or servers, mistakes made by coders writing smart contracts, and the potential for double-spend when projects exceed the value of their underlying blockchains mean decentralized finance needs to look at alternatives to blockchain. Post-blockchain distributed ledgers, such as directed acyclic graphs (DAG), which allow access to anyone and don’t rely on block producers, could provide an insight into how this industry evolves over the next decade.

Whatever form the new architecture takes is a prize waiting to be claimed. Only then will the industry finally live up to its promise and stop being associated with pyramid schemes.

Ex-Google and Meta Engineers Launch Nauma: Personalized Financial Planning Tools for Tech Professionals

Ex-Google and Meta Engineers Launch Nauma: Personalized Financial Planning Tools for Tech Professionals

SAN FRANCISCO, July 10, 2025 (GLOBE NEWSWIRE) — A team of former Google and Meta engineers has launched Nauma, a new platform designed to help people working in tech navigate complex financial decisions with confidence. Nauma’s mission is to democratize fiduciary-quality financial guidance, providing highly personalized planning tools without the high costs of traditional financial advisors.

Today, most high-net-worth families rely on advisors who charge based on Assets Under Management (AUM)—typically 1% of a client’s assets each year. For a family with $5 million, that means paying $50,000 annually, even as the level of service often remains static. Worse, these fees tend to rise 6–8% per year as portfolios grow, creating a system where costs scale without a proportional increase in value.

“The AUM model is outdated and misaligned with clients’ best interests,” said Alex Sukhanov, co-founder of Nauma. “Advisors operating under this model are incentivized to keep assets under their control, which can lead to biased advice when clients actually want to use their money—to buy real estate, start a business, or donate to charity.

Nauma is designed to give tech professionals clarity and control over their financial lives. The platform addresses the complex challenges faced by this group, including optimizing taxes, managing equity compensation, planning for early retirement, and protecting generational wealth.

“Tech professionals are building substantial wealth earlier in their lives, but most tools and advisors aren’t designed for their unique needs,” said Simone, Nauma’s co-founder. “We’re building the modern, intelligent financial planning infrastructure we wish we had—one that puts people, not assets, first.”

Do you really save money on Prime Day?

Do you really save money on Prime Day?

One of the biggest online shopping events of the year — Prime Day — will take place July 8-11 across 26 countries. What began in 2015 as a celebration of Amazon’s anniversary has since grown into a multiday retail extravaganza that rivals Black Friday and Cyber Monday in both hype and sales volume.

But amid the excitement, an important question remains: Do you really save money on Prime Day? Here’s what you need to know before loading up your virtual cart.

Prime Day is a global sales event created by Amazon that allows Prime members to access exclusive discounts and deals on a number of products across the site.

The first Prime Day took place a decade ago to mark Amazon’s 20th anniversary. It has since evolved to span several days throughout many countries, with this year’s Prime Day event being the longest so far at four days.

Shoppers can score limited-time deals on a wide range of products, from big-ticket electronics and home appliances to beauty products, clothing, and Amazon’s own devices like Echo speakers and Fire tablets. And millions participate each year. In 2024, global sales for Amazon Prime Day totaled $14.2 billion over a 48-hour period, according to Capital One Shopping Research.

Keep in mind that to access these deals, you must be a Prime member, which costs $14.99 per month or $139 per year. However, Amazon offers a free 30-day trial, allowing new users to shop the event without paying up front.

You may be wondering whether Prime Day is just another overblown shopping holiday like Black Friday, when retailers offer increasingly unimpressive deals to encourage unnecessary spending.

There’s no denying that some Prime Day deals offer real value. The key is having a smart shopping strategy in place to purchase items you actually need at a steep discount — not impulsively spending to take advantage of perceived savings.

Historically, shoppers have seen discounts of 30%-70% on items such as Apple AirPods, laptops, robot vacuums, smart home devices, and branded kitchen appliances. Amazon’s own products, including Kindles, Fire TVs, and Echo Dots, usually come with the deepest discounts. In 2023, Prime Day purchase discounts totaled $2.5 billion, according to Capital One.

Retail analysts have found that many of these items are offered at their lowest prices of the year. So yes, if you’ve had your eye on a specific product and it happens to be on sale during Prime Day, you could walk away with serious savings.

Keep in mind that not all the deals offered on Prime Day are really worth it. It’s important to have a plan and do your research ahead of time so you know whether you’re looking at a true discount.

One common tactic retailers use to encourage spending is “price anchoring,” where the listed original price is inflated, making the discount look more impressive than it actually is. In some cases, the so-called sale price is just a return to the item’s normal price after a brief increase in the weeks leading up to Prime Day.

Another issue is the impulse-buy nature of the event. Flash deals and lightning sales are designed to create urgency, leading many shoppers to make purchases they wouldn’t otherwise consider. If you buy something you don’t need — or wouldn’t have bought without the flashy red countdown clock — you’re not really saving money, even if the price is lower.

If you’re hoping to cash in on Amazon Prime savings, it’s important to make a game plan.

It’s easy to get distracted by discounts and make impulsive purchases while browsing. Before you start shopping, make a list of the key items you really want. Prioritize finding deals on those must-haves — and only buy them if it makes sense for your budget.

Decide how much money you can comfortably afford to spend on Prime Day ahead of time and stick to that limit. You’ll avoid throwing your budget off track and ending up with buyer’s remorse.

This year, Amazon is offering over 40 personalized deal features to help shoppers find discounts on products they’re most likely to be interested in. Look for personalized suggestions within the “Recommended deals for you,” “Top deals for you,” and “Customers’ Most-Loved” features to zero in on the deals you may be looking for.

Subscribe and save (if it makes sense)

Amazon’s Subscribe and Save feature offers year-round discounts on items you need to stock up on regularly. On Prime Day, these items may have an additional discount that could help you score extra savings.

Many major retailers such as Walmart, Target, and Best Buy will have their own sales and promotions around Prime Day when they know shoppers are in the mood to splurge. Before you check out, compare the price of items in your cart across a few different retailers to ensure you’re getting the lowest price overall.
