The evolution of the blockchain industry can be broadly divided into three phases, anchored by the progression of public chains. Bitcoin opened the door to "open money," liberating the imagination for decentralized currency. Ethereum's smart contracts unlocked the potential for applications, with components like stablecoins, lending protocols, and DEXs making decentralized "open finance" a reality. In the ideal next phase, "open finance" will expand to encompass all high-value data, moving toward an "open network."
As the scope of applications broadens, the inevitable increase in users and transactions will place higher demands on blockchain capacity, making scaling upgrades essential. To lead the "open network" era, major public chains have accelerated their progress this year, each showcasing their strengths to seize new positions in the future landscape.
Among these highly anticipated projects, NEAR Protocol stands out. It offers what the long-delayed Ethereum 2.0 promises: a Proof-of-Stake (PoS) mechanism, high transactions per second (TPS), and low gas fees. Additionally, NEAR focuses on interoperability with Ethereum through its Rainbow Bridge, supporting the Ethereum Virtual Machine (EVM) and its full suite of tools. This allows any user, app, or developer to permissionlessly transfer assets and experiences between Ethereum and NEAR.
Bridging Ecosystems with the Rainbow Bridge
At the heart of NEAR's strategy is the Rainbow Bridge, a trustless, permissionless, and fully decentralized bridge enabling interoperability between Ethereum and NEAR. This technology represents three critical advancements:
- Users and investors can move assets seamlessly between the two chains.
- Ethereum application developers can deploy EVM-based applications on NEAR without modifying their smart contract code, significantly enhancing performance.
- Developers and users of Ethereum DApps can experience ETH 2.0-like features without abandoning their existing community and ecosystem, using familiar tools like wallets.
The Rainbow Bridge operates using light clients that track each chain's state with minimal computation. An Ethereum light client, written in Rust, runs as a NEAR contract, while a NEAR light client, written in Solidity, runs as an Ethereum contract. These clients verify each other's states in a trustless manner, confirming finality before transferring data via a relay layer for cross-ecosystem use.
Compared to other interoperability solutions, NEAR's approach is highly targeted. While projects like Polkadot focus on connecting parallel chains (shards) within their ecosystem (homogeneous cross-chain), NEAR directly targets the vast Ethereum developer community. The Rainbow Bridge tackles the more complex challenge of heterogeneous cross-chain communication between two independent Layer 1 chains.
According to NEAR's Asia lead, Amos Zhang, the bridge's rollout is a three-step process: first, enabling asset migration; second, supporting EVM for direct cross-chain contract calls (contract migration); and third, fully supporting EVM's surrounding tools (experience migration).
For developers, NEAR supports smart contract development in Rust and AssemblyScript. Rust offers higher security, while AssemblyScript, based on JavaScript, caters to a larger developer community, enabling rapid front-end application development. The platform also provides integrated web-based IDE tools and features like NEAR Drop, which allows users to send tokens to individuals without a NEAR account, automatically registering them and optimizing the DApp onboarding process.

Fostering Growth with Grants and Accelerators
Attracting developers is only part of the equation. Sustaining them and providing support beyond initial funding is crucial. NEAR employs a dual model of Grants and the Open Web Collective (OWC) accelerator to nurture and solidify its developer community.
Grants are aimed at infrastructure tools with unclear盈利 models, such as wallets, indexers, block explorers, and even research-oriented projects. These projects can apply directly for financial support.
The OWC is an international blockchain accelerator for early-stage startups, not exclusively tied to the NEAR protocol. Each 12-week cohort includes 15 teams validating their ideas with help in product development, KPI setting, market discovery, and fundraising. The first cohort successfully raised over $15 million, and the second is already accepting applications.
Current Ecosystem and Future Roadmap
NEAR's ecosystem has seen significant growth since its mainnet transitioned to Phase 2 in October 2020, unlocking token transfers, account creation, validation participation, governance voting, and application deployment. The ecosystem map features prominent names like Chainlink, Maker, Aave, and IPFS, alongside numerous native projects.
Several key Ethereum projects have announced plans to expand to NEAR:
- Mintbase, an NFT platform, migrated to avoid Ethereum's high gas fees, leveraging NEAR's scalability and user-friendly experience.
- TrueUSD (TUSD), a top-five stablecoin, plans to launch on NEAR to benefit from lower fees and faster transaction finality.
- 1inch's automated market maker protocol, Mooniswap, will deploy on NEAR to explore cross-chain possibilities.
Native projects like the used mobile device marketplace Glyde, the horse racing game Zed Run, and the prediction market protocol Flux have already launched on NEAR. Flux users, for instance, can create and trade prediction markets with fees under $0.01.
By February 2021, an estimated 17 more applications are expected to go live on the mainnet, including P2P mobile gaming platforms, trader social networks, and DAO collaboration tools.
As of mid-November 2020, the NEAR mainnet had created 12,000 accounts, deployed 7,500 contracts, and processed 175,000 transfer transactions.
The Nightshade Sharding Protocol
Beyond the Rainbow Bridge, NEAR's other technical cornerstone is its novel sharding technology, known as Nightshade, designed for infinite scalability.
Unlike Ethereum 2.0 or Polkadot, which use a beacon chain/relay chain model with multiple shard chains, NEAR implements sharding within a single block. This architecture avoids the delays associated with cross-shard communication in other models, as transactions across shards can be confirmed in a single block. Nightshade also supports dynamic resharding, where the number of shards adjusts based on network usage. Each shard currently supports up to 1,000 TPS, and scalability is horizontal—10 shards can achieve 10,000 TPS, 100 shards 100,000 TPS, and so on, theoretically without limit.
The protocol also addresses state validity, data availability, and slashing mechanisms for malicious行为, earning NEAR the reputation as the "king of sharding."
NEAR vs. Ethereum 2.0: The Race for Open Network
NEAR and Ethereum 2.0 share a nearly identical vision: PoS consensus, scaling solutions, high TPS, and low gas fees. However, Ethereum 2.0 has faced repeated delays. Its phased rollout, expected to take years, involves staking (Phase 0), shard deployment (Phase 1), and activating transfers (Phase 2). Recent developer discussions have even suggested potentially delaying sharding in favor of rollups for Ethereum 2.0, pushing full sharding to a hypothetical "Ethereum 3.0."
This extended timeline creates a window of opportunity for other chains like NEAR to capture Ethereum's spillover value. Having launched its mainnet in just 26 months after project inception, NEAR's mainnet is already fully functional. Core developments, including sharding on the testnet and the full release of the Rainbow Bridge, are planned for 2021.
While Ethereum's massive ecosystem is a significant advantage, it also creates inertia, making upgrades slow and cumbersome. NEAR's post-advantage allows it to build with modern scalability and usability in mind from the ground up.
The relationship between technology and ecosystem is a classic "chicken and egg" problem. NEAR has chosen a path of pragmatic cooperation rather than attempting to颠覆 Ethereum outright. By providing底层 scalability, mid-layer optimizations, and mature application-layer tools, NEAR aims to offer a smooth, user-friendly experience that previews the functionality of Ethereum 2.0.

The Future of Open Network Competition
The next era of "open network" will likely be able to support several mainstream public chains cooperating through cross-chain interoperability. The current "king of public chains," Ethereum, is determined to defend its title but must overcome the challenges of upgrading a massive, live ecosystem.
Newer generation chains like NEAR have technical advantages over Ethereum 1.x, and their different strengths and backgrounds dictate their unique positioning. NEAR's team, comprised of alumni from Google, Facebook, and Microsoft with world-class programming competition backgrounds, has imbued the project with a focus on "sharding + usability + interoperability." Its commercial定位 is to provide "the fastest path to market for creators (developers, entrepreneurs)."
Under NEAR's open network vision, any business involving value transfer can be implemented on the blockchain. The future might not belong to a single chain but to four or five interoperable Layer 1 chains working together. In an open-source, collaborative blockchain world, mutual learning and joint effort are essential for long-term industry progress.
NEAR's market strategy is clear: first, bridge Ethereum's financial facilities to NEAR to break down ecological barriers and achieve rapid growth; second, build a variety of C-end applications on top of open finance, such as content platforms with creator monetization and online collaboration tools; finally, pioneer the open network era, returning data ownership to users.
