**"Our goal is to actually process 1 million transactions per second (TPS) within this year. We aim to enhance interoperability between different blockchains so that more nodes and chains can naturally connect to the NEAR ecosystem, creating an AI and blockchain environment where users can participate more easily."**
Bowen Wang, the founder of NEAR One—the core R&D organization overseeing the infrastructure development of NEAR Protocol (NEAR)—emphasized this in an interview with Bloomingbit on the 24th.
Founder Wang led the design and implementation of NEAR Protocol's sharding structure, 'Nightshade,' and has recently been spearheading the development of key technologies such as 'Stateless Validation' and an AI agent-based Blockchain Operating System (BOS). Bloomingbit met with Founder Wang through a video interview to delve deeply into NEAR Protocol's sharding technology structure, expansion strategy, and user-centric blockchain vision.
## Maximizing Blockchain Processing Speed with 'Sharding'
Bowen Wang emphasized that NEAR Protocol will clearly demonstrate how fast and flexibly it can expand through 'sharding.'
**Sharding** is a distributed processing technology used to maximize processing speed in databases and blockchains. In a blockchain structure where a single ledger is shared by all participants, bottlenecks occur when multiple users attempt to record transactions simultaneously. Sharding addresses this by splitting the ledger and installing multiple pipelines that can process transactions in parallel.
Originally emerging from existing database systems like Oracle, MySQL, and NoSQL, sharding is considered an 'extreme measure' for performance improvement. Although sharding has a high development complexity, it is highly effective in resolving bottlenecks and securing scalability.

Bowen Wang stated, "We will process 1 million transactions per second (TPS) within this year to prove how powerful our designed structure is," and "We will further develop the 'Chain Signatures,' a device that naturally connects various blockchains. We plan to bring more participants and external chains into NEAR."
The 1 million TPS target is a significant leap considering NEAR's current real-world performance. In reality, NEAR Protocol's average TPS is about 83. The recent maximum recorded was 4135 TPS, and theoretically, it can reach up to 12,000 TPS. For reference, Solana processes about 1150 TPS in real-time, with a theoretical maximum throughput of 65,000 TPS. In contrast, Ethereum's main network (mainnet) processes transactions at a rate of 15-30 per second.
NEAR is also rapidly preparing a foundation for AI agents. He stated, "We are making it so that AI can operate in a safe and personal environment, and we are developing a system where AI can make its own judgments and even learn in the future." He added, "Ultimately, our goal is to create an AI-based internet that is not centrally controlled but operated by users themselves." An 'AI agent' refers to an artificial intelligence system that performs various tasks autonomously without human intervention.
## Rapid Verification of Transaction Data with 'Zero-Knowledge Proof'
No matter how quickly data is recorded and processed, if the content is inaccurate, the trust in the blockchain system is difficult to maintain. The process of verifying whether transaction records are actually correct is essential, but it sometimes requires a lot of time and resources. NEAR plans to introduce cutting-edge cryptographic technology called **zero-knowledge proofs**—a leading-edge cryptographic technology to dramatically improve this process.
Founder Wang stated, "Currently, like most blockchains, NEAR uses Merkle proof to compactly verify some state data, but in the future, even this process will be replaced by a single small proof." He explained, "This proof is small, about a few hundred kilobytes (KB), but it verifies that the entire internal value of the blockchain has been correctly calculated at once. This will significantly reduce the cost and network transmission volume for data verification."
In particular, when this technology is applied, anyone can verify whether a block has operated correctly without having all the blockchain data. NEAR fundamentally utilizes a 'state witness' structure that extracts only the necessary data samples from each block to prove the entire state. This structure also compresses data, but if the state is complex, the proof file size can reach several megabytes (MB).
Founder Wang emphasized, "By incorporating zero-knowledge proof, even complex state computations can be compressed into a single proof of a few hundred kilobytes, drastically reducing overall verification costs."
In other words, a structure is being established where anyone can verify whether the entire network is functioning properly, even on lightweight devices or mobile environments. NEAR is moving towards a 'lightweight verifier system' that can verify core data without installing a full node that synchronizes all data.
## Sending Bitcoin with NEAR Wallet... How 'Chain Signatures' Changes Blockchain Usage
Since blockchains operate as independent networks, connecting different chains or moving assets between them remains a challenging task. Recent projects are also focusing on interoperability technology that connects blockchains that are isolated like islands. NEAR Protocol has introduced a **'Chain Signatures'** structure as a technology to solve this problem.
He stated, "With NEAR's Chain Signatures, you can send transaction commands directly to external blockchains like Ethereum, Solana, and Cosmos with a single NEAR wallet." In other words, an account on the NEAR blockchain holds addresses connected to each external chain, allowing it to create and send transactions that actually operate on those chains.

Transactions created in the NEAR wallet are transmitted to the external chain by an intermediary called a **'relayer.'** The relayer ensures that it is actually executed on the respective chain. For example, if a Bitcoin transfer command is created on NEAR, it is propagated on the Bitcoin network and operates immediately. It's as if the NEAR blockchain acts as a wallet for external blockchains.
For reference, NEAR is not the first to connect blockchains. The Cosmos ecosystem is also designed to send and receive messages between chains through a protocol called 'IBC (Inter-Blockchain Communication).' However, IBC requires the same access client to be installed on each chain and focuses on data transmission. In contrast, NEAR's Chain Signatures allows transactions to be constructed and executed directly on external chains at the account level, providing a much simpler and more intuitive user experience (UX) from the user's perspective.
## The Choice of Sharding... Capturing Both UX and Resilience with Architecture
Founder Bowen Wang also emphasized that NEAR Protocol aims to capture both user experience (UX) and resilience through the adoption of traditional sharding.
In the case of Ethereum, one of the leading blockchain representatives, it initially attempted to secure scalability by adopting sharding but has now shifted direction to a 'rollup' structure that processes computations on external networks and records only the results. Rollups are relatively simple to develop and have a low adoption barrier as they can be connected like an adapter to the Ethereum main chain. However, some opinions suggest that there are still various constraints in terms of user experience.
Founder Wang pointed out, "In the rollup structures used these days, users may have to move assets between multiple rollups and wait for 30 minutes. This UX feels more disconnected than a distributed ecosystem." He continued, "In contrast, NEAR Protocol allows users to process various requests seamlessly with a single account they own," emphasizing, "It is particularly low in entry barriers for new users." While choosing a traditional sharding structure increased development complexity, it resulted in a smoother UX.
Meanwhile, Founder Wang explained that a blockchain designed based on sharding can respond more stably in network congestion situations. He stated, "Solana can achieve very high performance thanks to its monolithic architecture optimized closely with hardware, but we saw its structure shake under extreme loads over the past year. We also had similar congestion situations, but we could mitigate the problem by splitting shards." He added, "Although the horizontal expansion method based on sharding is more complex in structure, we have become convinced that it is ultimately more stable and advantageous."
NEAR completed this mechanism last March, expanding from 6 to 8 shards on the mainnet and testing actual performance to secure data on it.
Founder Wang explained, "We confirmed through testing that the processing speed actually increases as the number of shards increases to a certain extent." However, he noted, "Just because there are 10 shards doesn't mean it's necessarily 10 times faster than when there is 1," and "As the number of shards increases, the resources and time required to coordinate them also increase." He particularly mentioned, "If the number of shards approaches 100, bottlenecks can occur in the process of aligning information between shards," and "This is one of the important technical challenges we need to solve in the future."
## The Core of NEAR Protocol's Shard Expansion Strategy is 'Nightshade'

Nightshade is NEAR blockchain's proprietary sharding structure, designed as an expansion technology that automatically splits or merges chains according to traffic conditions. The name "Nightshade" was inspired by Spensa Nightshade, the protagonist of Brandon Sanderson's science fiction novel "Skyward," who overcomes her own limitations and carves out her own path.
To deeply understand what NEAR's core technology model 'Nightshade' is, it is necessary to first understand NEAR Protocol's sharding structure. NEAR Protocol supports both 'transaction sharding' and 'state sharding' processing methods. It also has a structure where validators are randomly assigned to shards and verify data in each block.
Transaction sharding refers to distributing a large list of pending transactions across multiple pipelines for parallel processing. State sharding, on the other hand, involves breaking down and distributing the "state" data within each transaction—such as account balances or smart contract variables—into separate parts. (In blockchain, "state" refers to the entire store of network data: user accounts, token balances, contract variables, and more. Every transaction that occurs updates this global state.) One method spreads out the transaction count; the other breaks down the internal complexity of each transaction.
Based on the 'Nightshade' technology, NEAR Protocol utilizes both transaction sharding and state sharding to not only increase the overall speed by finely dividing the blockchain but also implement a 'flexible structure' that automatically splits or merges the network according to the situation.

In reality, NEAR Protocol continues to develop to optimize the number of shards according to network conditions. Founder Wang stated, "Currently, the shard structure is fixed, but ultimately, we aim for a system that automatically splits and merges shards according to network load. For example, if there is congestion at one point, causing overload, the shard is split into two, and conversely, if both shards are idle, they are merged back into one." This is similar to increasing lanes when cars are crowded on the road and reducing them when it is quiet.
Until now, shards have been manually adjusted to match network throughput, but in the future, the blockchain itself will determine when to split and merge shards based on indicators such as traffic load and resource usage.
Last August, NEAR Protocol launched 'Nightshade 2.0' with this goal, undertaking a major structural overhaul to simultaneously enhance scalability and security. Previously, creating a new shard required building separate state data over several hours. In contrast, the new structure transitions to a method where shards are split and verified within a single block. This structural improvement allows for real-time shard expansion while conserving resources.
Founder Wang emphasized, "We are simultaneously elevating the scalability and user experience of the blockchain. Our ultimate goal is to implement a pleasant blockchain operating system where AI agents can operate autonomously on top of it." This aligns with NEAR's long-term vision of creating a blockchain environment that supports real-time applications and on-chain automation, allowing users to intuitively utilize it.
