In the past few years, Proof-of-Stake (PoS) has become the mainstream choice for second-generation public blockchains, with nearly 80% of new chains adopting staking consensus. However, the debates have intensified: Is decentralization being reshaped by capital? Is blockchain security being “financialized”? Is governance increasingly controlled by whales?
In this Space session, we explored a fundamental question: In today’s PoS-dominated environment, why is PoW still irreplaceable? Below is a structured recap of the conversation.
Q1: Starting with Bitcoin — What problem was PoW originally designed to solve?
IVAN: PoW was not created for “performance.” It answered a more fundamental challenge: How can untrusted strangers establish immutable consensus without a central institution?
Before Bitcoin, all currencies and ledgers relied on centralized trust. PoW transformed the “right to record transactions” into a globally open activity, accessible to anyone willing to expend real-world resources (electricity, hardware, computation).
It introduced three core shifts:
- Power redistribution: Power stems from contributed computing power, not identity or capital.
- Attack costs become physical: Attacks require energy and hardware, not purely financial tokens.
- Unprivileged design: No one starts with governance privileges.
Together, these form the true foundation of decentralization—not just a marketing term.
Q2: What problems does PoS solve, and at what cost?
IVAN: PoS improves two major pain points of PoW: energy consumption and efficiency. By staking tokens instead of competing through computation, PoS chains offer:
- Faster block times
- Lower energy consumption
- Higher TPS
- Easier governance and upgrades
However, PoS shifts security from physical computing power to capital itself, making network safety depend on:
Security ≈ Token concentration ≈ Who controls more capital.
This may gradually evolve into capital-governed networks dominated by institutions and whales.
Q3: Why is PoW considered “physically secure,” while PoS is “capital-secure”?
IVAN: PoW security is rooted in physical-world constraints—electricity, chips, hardware, geography. These cannot be manipulated instantly through financial operations.
To attack a PoW network, one must build real mining farms and infrastructure—slow, costly, and difficult.
PoS security, however, is based on token ownership and validator control, which exist entirely in the realm of finance—subject to speculation, lending, leverage, and collusion.
This is why PoW remains preferred for long-term value storage and global settlement layers.
Q4: Does PoW make “the rich richer”? Which system risks greater centralization?
IVAN: Contrary to intuition, long-term data suggests PoS is more prone to centralization.
PoS is a compound-interest machine:
More stake → more rewards → faster whale growth → stronger governance control.
PoW is cost-based competition:
Returns depend on continuous real-world expenditures (energy, hardware, maintenance), preventing exponential compounding.
BTC ownership may concentrate, but BTC’s hashrate has never been monopolized by any nation or institution. You can buy tokens—but you cannot conjure computing power out of thin air.
Q5: Amid energy criticism, is PoW entering a “new energy era”?
Ethues: Absolutely. Next-generation PoW is evolving:
- From consumption → to idle energy utilization: using hydropower, wind power, abandoned and redundant energy globally.
- From single-purpose → to multi-purpose computing power: rendering, AI training, privacy computing, security verification.
PoW is no longer just about mining tokens—it is becoming a foundational Web3 computing layer.
Q6: Why does INIChain insist on PoW instead of PoS?
Ethues: INIChain focuses on long-term security of privacy computing, not performance racing.
PoS secures the network based on who owns more tokens. PoW secures the network based on who pays real-world costs. For privacy computing, we require physical security, not financial speculation.
INIChain will handle financial data, AI models, and sensitive corporate information. If capital can manipulate the consensus, privacy becomes meaningless.
Thus, PoW is chosen for its openness, neutrality, and real-world cost foundation.
Q7: How does INIChain balance security, performance, and cost?
Joseph: Traditional PoW improves security through higher energy use—but this increases cost and reduces decentralization.
INIChain innovates through:
- DDA (Dual Dynamic Allocation) mechanism
- VersaHash algorithm
- Parallel block architecture
This creates two simultaneous block types:
High-privacy computing blocks
For TFHE-based encrypted computation. The network automatically increases verification difficulty and rounds to ensure absolute security.
Standard transaction blocks
For ordinary transfers—optimized for low gas and high TPS.
Parallel generation prevents network-wide congestion.
VersaHash dynamically increases or decreases difficulty based on task type, creating an efficient “smart transportation system” for computation.
Q8: What role will INIChain’s PoW play in Web3?
Joseph:
Bitcoin’s PoW created decentralized digital gold.
INIChain’s PoW aims to build decentralized privacy computing infrastructure.
The future of Web3 will require:
- AI training and inference on-chain
- Real-time, compliant financial risk control
- Enterprise-level collaboration
- Frictionless data asset circulation
All of this needs a stable, censorship-resistant, incorruptible foundation. PoW remains the most irreplaceable “anchor of trust.”
Conclusion
PoW is not outdated—it has simply been misunderstood. If PoS is faster and more capital-friendly, PoW is more robust and closer to true decentralization.
As privacy computing, AI, enterprises, and RWAs move on-chain, the demand for long-term, censorship-resistant security will surge. Next-generation PoW—tested by energy and time—will remain the backbone.
