Blockchain promised a decentralized utopia—a financial system free from intermediaries, powered by code and community. Yet, as decentralized finance (DeFi) exploded onto the scene, it brought with it a paradox: sky-high yields that dazzled investors but crumbled under scrutiny, exposing the absence of real world yield behind many of those promises.
From the euphoric highs of DeFi Summer 2020 to the catastrophic collapse of Terra Luna, the industry has been trapped in a cycle of "ponzinomics"—a term that’s become synonymous with unsustainable tokenomics and illusory rewards, casting serious doubt on the credibility of yield generation on blockchain.
Today, as the dust settles, real world yield is emerging as a new paradigm, shaping the future of DeFi. By anchoring blockchain to genuine economic value, this approach offers a sustainable future, with projects like Zeebu leading the charge in transforming industries like telecoms. Let’s unpack why the old ways failed, how real technology can solve real problems, and why this shift is blockchain’s next frontier.
The Broken Promise of DeFi Ponzinomics: A History Lesson
DeFi took off like a rocket in DeFi Summer 2020, fueled by sky-high yields and a frenzy of excitement. Protocols waved 100%-1000% APYs (Annual Percentage Yields) like bait, pulling liquidity providers in and boosting Total Value Locked (TVL) from $1 billion to over $10 billion between June and September—three months of pure chaos. It felt like a crypto gold rush, but here’s the hidden secret: those gains weren’t from real profits. They came from cranking out new tokens and handing them out like flyers, a trick that couldn’t last. The high yields? A shiny illusion propped up by inflation, not actual value, far from real world yield.
To understand how it took shape, let's dive into the rise and peak of Ponzinomics.
Ponzinomics—the practice of generating yields through token emissions rather than organic revenue—took root in 2020 and reached its zenith by early 2022. It began with the introduction of liquidity mining and yield farming in 2020, which rewarded users with tokens for lending and borrowing. The model spread like wildfire: stake assets, earn tokens, and watch your APY soar into triple digits. More and more projects adopted similar mechanisms, offering yields as high as 1,000% to attract liquidity. Total Value Locked (TVL) in DeFi protocols exploded from $1 billion in June 2020 to $248 billion by December 2021, per DeFiLlama, a 248x increase in 18 months.
The peak of ponzinomics came with algorithmic stablecoins, which promised a $1 peg without traditional collateral, relying on token incentives to balance supply and demand. Projects like Terra’s UST and Iron Finance’s IRON epitomized the trend, offering high yields to bootstrap adoption. At its height in early 2022, Terra’s ecosystem alone was valued at $60 billion, with Anchor Protocol dangling a 20% APY on UST deposits. But the cracks were already forming—yields were subsidized by treasury funds, not revenue, and the system’s stability hinged on speculative demand. When that demand faltered, ponzinomics unraveled, leading to some of DeFi’s most infamous collapses.
The Ouroboros Critique: Vitalik’s Call for Real World Yield
Ethereum co-founder Vitalik Buterin has consistently raised concerns about DeFi’s approach to generating yields, describing it as an “ouroboros”—a snake eating its own tail. He voiced his lack of enthusiasm for the 2021 liquidity farming trend, noting that its appeal stemmed from short-lived token issuance rather than enduring value. He emphasized his critical stance by questioning the source of yields whenever they’re pitched as attractive.
He stressed that for DeFi to thrive, its yields must stem from real, sustainable demand rather than the constant creation of new tokens. His vivid analogy reflects a growing view in the crypto space: DeFi needs to move away from speculative tactics and focus on building lasting, practical value that drives real world yield.

Summing Up: Ponzinomics & Real World Yield
The failures of ponzinomics highlight the urgent need for the future of DeFi to pivot toward real world value in crypto:
- Token-Driven Yields: High APYs were funded by token emissions, not revenue. When demand slowed, dilution crashed prices.
- Reflexivity: Confidence drives markets. Once trust is broken, feedback loops accelerate the collapse.
- Lack of Real Backing: The reliance on speculation and token emissions failed when their volatile token crashed.
- Social Dynamics: Crypto thrives on narratives. Terra’s “steady lads” and Iron Finance’s Mark Cuban saga turned financial disasters into viral moments, amplifying panic and eroding trust.
The bear market laid bare the consequences with TVL falling from $248 billion in December 2021 to $66 billion by June 2023, a 73% drop. Projects built on ponzinomics couldn’t survive without constant inflows—users fled, liquidity dried up, and token values hit rock bottom.
Real World Yield: A Sustainable Alternative for the future of DeFi
The next evolution of blockchain and the future of DeFi doesn't live in the hypothetical—it lives in the tangible. "Real World Yield" refers to blockchain-based systems that generate returns from actual economic activity, not speculative tokenomics.
This shift is not just timely—it’s essential. Instead of relying on ever-growing token emissions or pyramid-shaped incentive models, real world yield protocols aim to solve real-world problems and extract value from actual use cases.
Real world yield grounds blockchain in the real economy while offering a way out, tying returns to genuine economic activity rather than token inflation. In DeFi, this means protocols generating revenue from user activity, not emissions, and this model of yield generation on blockchain is already being demonstrated by several blue-chip protocols.
Examples include:
- Uniswap: Liquidity providers earn trading fees, not token handouts. In February 2024, Uniswap generated $60 million in fees, per Token Terminal.
- Aave: Lenders earn interest from borrowers based on market demand. Aave’s TVL held at $5 billion in 2023, per DeFiLlama, thanks to real revenue.
The true potential lies in real yield DeFi protocols that apply blockchain to real-world industries and generate yield from tangible cash flows. This is where projects like Zeebu are making waves.
Zeebu: Real World Yield in Telecoms
Zeebu is addressing inefficiencies in the multi-billion dollar telecom pre-payment industry, where cross-border payments are slow, costly, and opaque. Using blockchain, Zeebu enables instant settlements and transparent invoicing for telecom carriers. As of April 10, 2025, it has processed over $7 billion in settlements, managing 110k+ invoices for 140 telecom institutions.
But what makes Zeebu truly unique is how it generates and distributes real, protocol-driven yield.
Unlike legacy DeFi models where rewards are inflated through token minting, Zeebu’s yield is backed by verified telecom settlement flows. Here's how the mechanism works:
- Transactional Revenue from B2B Payments: Every invoice settled via Zeebu’s on-chain infrastructure incurs a fee, which is collected by the protocol.
- Decentralized Liquidity Contribution: This fee pool is then redistributed to contributors of network — liquidity providers, delegators, and deployers—based on their role and stake in the system.
- Stablecoin-Based Rewards: Yield is distributed in stable assets, derived directly from transaction revenue, ensuring sustainability and value retention.
This architecture enables a new yield category—enterprise-grade real yield—generated by global carriers settling real invoices on-chain, not transient capital rotating through protocols.
The Road Ahead: Where Real Value Meets Real Innovation
The blockchain space is maturing. Investors, users, and builders alike are demanding more than just promises—they want performance, transparency, and durability. Real World Yield delivers all three, positioning itself as the foundation for DeFi with sustainable yield beyond the chaotic first wave.
Zeebu exemplifies this transition. By focusing on a specific vertical—B2B settlements—and solving industry-specific pain points, Zeebu showcases the power of blockchain bridging real and digital economy.
As more projects follow suit and real world yield becomes the gold standard, the future of defi will look less like a casino and more like a well-oiled machine powering global industries.
The hype cycles will come and go. But platforms that focus on yield generation on blockchain through real-world applications? Those are here to stay—and they define the future of DeFi.
