Polkadot has captured significant market attention, with supporters believing it could surpass Ethereum, while skeptics worry it might follow EOS's path of decline. The outcome remains to be seen and is worth watching closely.
After climbing into the top five cryptocurrencies by market capitalization, Polkadot (DOT) has garnered widespread interest. Its architecture, featuring a relay chain connected to multiple parallel chains, enables interoperability between different blockchains, expanding its potential use cases.
Over 120 projects are already building within the Polkadot ecosystem. Although its mainnet hasn’t officially launched, Polkadot has already captured the market’s imagination. Many are calling it the next "Blockchain 3.0."
Given its ambitious vision, Polkadot is often compared to EOS and Ethereum. The former has seen its star fade over time, while the latter remains the leading smart contract platform. These two are often seen as representing the potential floor and ceiling for Polkadot’s future.
From a technical and architectural standpoint, Polkadot operates at a higher dimension. It allows developers to build their own parallel chains and serves as an infrastructure for creating new blockchains, aiming to achieve cross-chain interoperability. However, this path is challenging. Investors who experienced the disappointment of EOS are cautious. Until Polkadot’s vision becomes reality, lessons from the past can offer valuable insights.
The Rapid Expansion of the Polkadot Ecosystem
Few were surprised by Polkadot’s rapid rise.
According to data from CoinGecko on September 14, DOT reached a market capitalization of $4.747 billion, ranking fifth among all cryptocurrencies. This achievement came less than a month after the token’s transfer functionality was enabled, highlighting strong market confidence in this young project.
Polkadot is increasingly moving beyond its abstract definition as a "cross-chain明星." Its structure—centered around a relay chain that connects multiple parallel chains—demonstrates high scalability. Many now view it as a "universal public chain."
How the Relay Chain and Parachains Work Together
In Polkadot, the relay chain acts as a central coordinator. Validators stake DOT to verify proofs from parallel chains and reach consensus with other validators, ensuring the relay chain remains secure. Parallel chains follow instructions from the relay chain to exchange information and process transactions.
The Polkadot team offers a clearer explanation: as a network protocol, Polkadot can transfer any data—not just tokens—across blockchains. This makes it a true multi-chain application environment, enabling operations like cross-chain registration and computation. For example, a university’s private blockchain for academic records could send a verification proof to a public smart contract on another chain.
The ability for chains to interact gives Polkadot nearly limitless potential. Like Ethereum and EOS before it, Polkadot has quickly become a popular development platform, attracting numerous builders.
A Thriving Ecosystem of Applications
The Polkadot ecosystem already includes a wide range of applications: oracles, DAOs, DeFi protocols, smart contracts, games, wallets, infrastructure tools, explorers, and forums. According to estimates, at least 120 projects are developing applications and services on Polkadot, including well-known names like ChainLink, ChainX, IPSE, and Celer Network.
Even before its mainnet launch, Polkadot is already fostering innovation. Any project associated with its ecosystem receives considerable market attention.
On September 11, Phala Network—a privacy-focused parallel chain—was listed on Huobi’s observation zone. Within four days, its token price rose from $0.01 to a high of $0.21, a 21x increase. Polkadot is becoming synonymous with new investment opportunities.
Comparisons with EOS and Ethereum
Given its top-five market cap and high expectations, Polkadot is often compared to Ethereum and EOS—especially since they share certain similarities.
As Polkadot’s market value soared, some in the crypto community expressed skepticism, referring to it as "the next EOS." In reality, the two projects differ significantly in technical design, positioning, and consensus mechanisms.
Polkadot, designed as a "multi-chain environment," uses a Nominated Proof-of-Stake (NPoS) mechanism. The system selects validators with the largest total stake and removes those with lower stakes, making it difficult for malicious actors to become validators. This differs from EOS, where voting weight is proportional to the amount staked. Polkadot gives equal voting power to selected validators, promoting fairness and security.
Despite technical differences, the market perception of Polkadot and EOS shows similarities.
EOS raised $4 billion during its initial coin offering (ICO) amid high expectations. Polkadot raised approximately $145 million through a Dutch auction in October 2017, followed by two additional rounds in June 2019 and July 2020, bringing the total to over $250 million. Notably, EOS fundraised during the peak of ICO mania, while Polkadot succeeded in a more regulated environment.
Substantial funding allowed both projects to start with strong financial backing. As leading blockchain infrastructures, both were hailed as "Blockchain 3.0" even before their mainnets went live, with ecosystems that grew rapidly.
Another commonality is the reputation of their founders. EOS was created by Dan Larimer (BM), who developed the first decentralized exchange (BitShares) and the blockchain-based social media platform Steemit. Polkadot was founded by Gavin Wood, a co-founder and former CTO of Ethereum.
These similarities are closely watched by experienced investors. EOS has since fallen from grace: its DApp ecosystem stagnated, BM became less involved, and its token price plummeted. Investors who suffered losses are wary that Polkadot’s hype might lead to a similar letdown.
However, one EOS community member noted that EOS’s decline was largely due to mismanagement by BM and the Block.one foundation. While they delivered a technical framework, they failed to support the ecosystem. Polkadot, in contrast, has taken a different approach.
To encourage development, Gavin Wood established the Web3 Foundation, which funds community projects including interoperability modules, specialized parallel chains, and blockchain explorers.
Additionally, Polkadot’s website provides detailed tutorials on building parallel chains and offers a modular framework to help teams develop new chains quickly.
Compared to BM, Gavin Wood is perceived as more technically focused and hands-on. Some investors believe BM was more talk than action, while Wood has consistently contributed to Polkadot’s development—especially on the technical side. For example, while EOS super nodes could earn substantial profits, Polkadot’s design includes more meticulous rules. "Even if someone holds many DOT tokens, if their parallel chain lacks utility, they won’t profit," one observer noted.
A Higher-Dimension Ethereum?
At this stage, Polkadot appears to have greater potential than EOS. But how does it compare to Ethereum, the widely respected leader in smart contract platforms?
Although Polkadot is rising quickly, it is still in its infancy compared to Ethereum. Earlier, its testnet Kusama experienced downtime and halted block production, causing some concern.
Gavin Wood acknowledges that challenges and unexpected problems are normal. It’s easy to propose grand visions, but turning them into functional, practical products is far more difficult.
The market is increasingly understanding Polkadot’s positioning. Wood has described Ethereum as an experiment—a prototype to test technological feasibility. "It was like my school; I graduated from Ethereum and wanted to try more things," he said.
In his view, one key difference is that Polkadot users don’t pay gas fees to validators (miners). Moreover, on Polkadot, users can design not only smart contracts but also their own chains and economic models—something not possible on Ethereum.
Why Developers Choose Polkadot
Crust Network, a decentralized storage incentive layer protocol, had to choose between Ethereum and Polkadot. According to CPO Dean, the team encountered several issues on Ethereum, including high gas fees, low transaction throughput, limitations in development tools, and state explosion.
Polkadot, having learned from these challenges, offers certain advantages. Dean cited its high throughput, cross-chain capabilities, and flexible heterogeneous parallel chain design. Additionally, Polkadot’s governance and upgrade processes are simpler, supporting forkless upgrades. Crust ultimately chose Polkadot due to better alignment—especially its off-chain worker mechanism, which supports strong chain-to-chain interaction, ideal for Crust’s storage and retrieval service market.
Phala Network partner佟林 believes Polkadot and Ethereum are complementary. Ethereum 2.0 addresses scalability through homogeneous sharding, while Polkadot solves heterogeneous sharding and cross-chain expansion. Together, they could cover over 99.9% of blockchain use cases.
A common analogy is that Ethereum is best suited for token issuance (most tokens are ERC-20), while Polkadot’s parallel chains enable new blockchain creation. They operate at different dimensions. "The future of blockchain is cross-chain interoperability, so Polkadot has an advantage in this regard," an industry insider commented.
