Introduction: A Technical Breakthrough for Blockchain Performance Bottlenecks
Over the more-than-ten-year history of blockchain technology, performance bottlenecks have consistently been the core obstacle blocking large-scale adoption. Ethereum can only process 15 transactions per second, with confirmation times as long as 12 seconds — performance that clearly cannot meet growing application demand. Traditional blockchains' serialized execution model and limited computing power leave system throughput severely constrained.
Bitroot was created precisely to break through this impasse. Through four major technical innovations — the Pipeline BFT consensus mechanism, optimistic parallel EVM, state sharding, and BLS signature aggregation — Bitroot achieves a performance breakthrough of 400-millisecond finality and 25,600 TPS, providing an engineered technical solution for large-scale blockchain adoption.
This article systematically lays out Bitroot's core technical architecture and design philosophy, algorithmic innovations, and engineering practice, offering a complete technical blueprint for high-performance blockchain systems.
I. Technical Architecture: The Engineering Philosophy of Layered Design
1.1 The Five-Layer Architecture
Bitroot follows the classic layered architecture paradigm, building five core layers from the bottom up, each with clearly defined functionality and responsibilities. This design achieves clean module decoupling while laying a solid foundation for the system's scalability and maintainability.
The storage layer is the foundation of the whole system, responsible for persisting state data. It uses an improved Merkle Patricia Trie structure for state tree management, supporting incremental updates and fast state proof generation. To address the state bloat that blockchains commonly face, Bitroot introduces a distributed storage system that shards large data across the network, keeping only hash references on-chain. This design effectively relieves the storage burden on full nodes, letting ordinary hardware participate in network validation.
The network layer builds a robust peer-to-peer communication infrastructure. It uses a Kademlia distributed hash table for node discovery and the GossipSub protocol for message propagation, ensuring information spreads efficiently across the network. Notably, for large-scale data transfer needs, the network layer specifically optimizes large-packet transmission, supporting sharded transfer and resumable transmission, which significantly improves data synchronization efficiency.
The consensus layer is at the core of Bitroot's performance breakthrough. By integrating the Pipeline BFT consensus mechanism with BLS signature aggregation, it pipelines the consensus process. Unlike traditional blockchains that tightly couple consensus and execution, Bitroot fully decouples the two — the consensus module focuses on quickly determining transaction order, while the execution module processes transaction logic in parallel in the background. This design lets consensus keep advancing continuously without waiting for execution to finish, substantially boosting system throughput.
The protocol layer is where Bitroot's technical innovations converge. It achieves full EVM compatibility, ensuring smart contracts from the Ethereum ecosystem can migrate seamlessly, and — more importantly — implements a parallel execution engine that, through a three-stage conflict detection mechanism, breaks past the single-threaded limits of traditional EVM and fully unlocks the computing potential of multi-core processors.
The application layer gives developers a rich toolchain and SDKs, lowering the barrier to building blockchain applications. Whether it's DeFi protocols, NFT marketplaces, or DAO governance systems, developers can build applications quickly through standardized interfaces without needing to understand the underlying technical details in depth.

1.2 Design Philosophy: Finding the Optimum Within Tradeoffs
Throughout the architecture design process, the Bitroot team faced numerous technical tradeoffs, each decision shaping the system's final form in a meaningful way.
Balancing performance and decentralization is an eternal theme in blockchain design. Traditional public chains often sacrifice performance in pursuit of maximal decentralization, while high-performance consortium chains trade away decentralization for speed. Bitroot finds a clever balance through its dual-pool staking model: the validator pool handles consensus and network security, guaranteeing decentralization of the core mechanism, while the compute pool focuses on executing computational tasks and can run on higher-performance nodes. Dynamic switching between the two pools is supported, preserving the system's security and decentralization while still making full use of high-performance nodes' computing power.
The tradeoff between compatibility and innovation is just as much a test of design judgment. Full EVM compatibility means seamlessly inheriting the Ethereum ecosystem, but it also means being constrained by EVM's design limits. Bitroot chose a path of incremental innovation — keeping the core EVM instruction set fully compatible to guarantee zero-cost migration for existing smart contracts, while introducing new capabilities through an extended instruction set, leaving ample room for future technical evolution. This design lowers the cost of ecosystem migration while still opening the door to innovation.
Coordinating security and efficiency matters especially in a parallel-execution setting. Parallelized execution can substantially boost performance, but it also introduces new security challenges such as state-access conflicts and race conditions. Bitroot's three-stage conflict detection mechanism performs detection and verification before, during, and after execution respectively, ensuring the system maintains state consistency and security even in a highly parallel environment. This layered protection lets Bitroot pursue extreme performance without sacrificing security.
II. Pipeline BFT Consensus: Breaking Free of Serialization
2.1 The Performance Bind of Traditional BFT
Byzantine Fault Tolerant (BFT) consensus, proposed by Lamport and others in 1982, has become the theoretical cornerstone of fault tolerance in distributed systems. However, classic BFT architectures, in pursuing security and consistency, also expose three fundamental performance limitations.
Serialized processing is the primary bottleneck. Traditional BFT requires each block to wait for the previous block to be fully confirmed before consensus on it can begin. Take Tendermint as an example: its consensus involves three phases — Propose, Prevote, and Precommit — each of which must wait for votes from more than two-thirds of validator nodes, with block height advancing strictly in sequence. Even if nodes are equipped with high-performance hardware and ample network bandwidth, none of that can be used to speed up the consensus process. Ethereum's PoS takes 12 seconds to complete a round of confirmation; Solana, though it shortens block production to 400 milliseconds via its PoH mechanism, still needs 2-3 seconds for final confirmation. This serialized design fundamentally caps how much consensus efficiency can be improved.
Communication complexity grows quadratically with the number of nodes. In a network with n validator nodes, each round of consensus requires O(n²) message transmissions — every node must send messages to every other node while also receiving messages from all of them. When the network scales to 100 nodes, a single round of consensus already involves processing close to ten thousand messages. Worse, each node must verify O(n) signatures, so verification overhead grows linearly with the number of nodes. In a large-scale network, nodes spend enormous amounts of time on message handling and signature verification rather than on actual state-transition computation.
Low resource utilization also gets in the way of performance optimization. Modern servers are typically equipped with multi-core CPUs and high-bandwidth networking, but traditional BFT's design philosophy dates back to the single-core era of the 1980s. While a node waits for network messages, its CPU sits largely idle; while it's busy computing signature verifications, network bandwidth goes underused. This imbalance in resource utilization leads to suboptimal overall performance — even throwing better hardware at the problem yields very limited gains.
2.2 Pipelining: The Art of Parallel Processing
Pipeline BFT's core innovation is pipelining the consensus process, letting blocks at different heights undergo consensus in parallel. The design draws inspiration from the instruction pipelines of modern processors — while one instruction is in its execution stage, the next can simultaneously be decoded, and the one after that can be in its fetch stage.
The four-stage parallel mechanism is the foundation of Pipeline BFT. The consensus flow is broken into four independent stages — Propose, Prevote, Precommit, and Commit. The key innovation is that these four stages can overlap: while block N-1 is in its Commit stage, block N can simultaneously be in Precommit; while block N is in Precommit, block N+1 can simultaneously be in Prevote; while block N+1 is in Prevote, block N+2 can begin its Propose stage. This design keeps the consensus flow running continuously like a pipeline, with multiple blocks being processed at different stages at any given moment.
In the Propose stage, the leader node proposes a new block, including the transaction list, block hash, and a reference to the previous block. To guarantee fairness and prevent single points of failure, the leader is elected on a rotating basis via a verifiable random function (VRF). The VRF's randomness is derived from the hash of the preceding block, ensuring no one can predict or manipulate the leader election outcome.
The Prevote stage is where validator nodes give preliminary approval to the proposed block. After receiving the proposal, a node verifies the block's validity — whether transaction signatures are valid, whether state transitions are correct, whether the block hash matches. Once verification passes, the node broadcasts a prevote message containing the block hash and its own signature. This stage is essentially a straw poll, probing whether enough of the network approves of this block.
The Precommit stage introduces a stronger commitment semantics. Once a node has collected prevotes from more than two-thirds of the network, it's confident that a majority approves of the block, and so it broadcasts a precommit message. A precommit is a commitment — once a node sends a precommit, it cannot vote for a different block at the same height. This one-way commitment mechanism prevents double-voting attacks and ensures the security of consensus.
The Commit stage is the final confirmation. Once a node has collected precommits from more than two-thirds of the network, it's confident the block has achieved network consensus, and formally commits it to local state. At this point the block reaches final confirmation and cannot be rolled back. Even in the event of a network partition or node failure, a block that has already been committed will not be reverted.

A state-machine replication protocol keeps the distributed system consistent. Each validator node independently maintains its consensus state, including the height, round, and step currently being processed. Nodes synchronize state by exchanging messages — on receiving a message for a higher height, a node knows it has fallen behind and needs to catch up; on receiving a message for a different round at the same height, a node determines whether it needs to move to a new round.
State-transition rules are carefully designed to guarantee both safety and liveness: after a node receives a valid proposal at height H, it moves into the Prevote step; once it collects enough prevotes, it moves into Precommit; once it collects enough precommits, it commits the block and advances to height H+1. If a step transition isn't completed within the timeout window, the node advances the round and starts over. This timeout mechanism prevents the system from stalling permanently under abnormal conditions.
Intelligent message scheduling ensures messages are processed correctly. Pipeline BFT implements a Height-based Message Priority Queue (HMPQ) that computes message priority from its block height, round, and step. Messages at a higher height get higher priority, so consensus keeps moving forward; within the same height, round and step also affect priority, preventing stale messages from interfering with the current round of consensus.
Message-handling strategy is also carefully designed: messages from the future (height above the current height) are cached in a pending queue, waiting for the node to catch up; messages at the current height are processed immediately, driving consensus forward; severely stale messages (height far below the current height) are discarded outright, avoiding memory leaks and wasted computation.
2.3 BLS Signature Aggregation: A Cryptographic Force Multiplier
With a traditional ECDSA signature scheme, verifying n signatures takes O(n) time and storage. In a network with 100 validator nodes, every round of consensus requires verifying 100 signatures, with signature data taking up about 6.4KB. As the network scales, signature verification and transmission become a serious performance bottleneck.
BLS signature aggregation delivers a breakthrough at the cryptographic level. Based on the BLS12-381 elliptic curve, Bitroot achieves genuine O(1) signature verification — no matter how many validator nodes are involved, the aggregated signature is a constant 96 bytes, and verification requires only a single pairing operation.
The BLS12-381 curve provides 128-bit security, meeting long-term security requirements. It defines two groups, G1 and G2, plus a target group GT. G1 is used to store public keys, with each element taking 48 bytes; G2 is used to store signatures, with each element taking 96 bytes. This asymmetric design optimizes verification performance — computing with G1 elements is cheaper in a pairing operation, and placing public keys in G1 takes advantage of exactly that.
The mathematics behind signature aggregation rests on the bilinear property of the pairing function. Each validator node signs a message with its private key, producing a signature point in group G2. After collecting multiple signatures, group addition combines them into an aggregated signature. The aggregated signature is still a valid point in G2, and its size stays constant. To verify, only a single pairing operation is needed to check whether the aggregated signature and the aggregated public key satisfy the pairing equation — confirming the validity of all the original signatures at once.
A threshold signature scheme further strengthens the system's security and fault tolerance. Using Shamir secret sharing, a private key is split into n shares, and at least t shares are required to reconstruct the original key. This means that even if t-1 nodes are compromised, an attacker still cannot obtain the complete private key; at the same time, as long as t honest nodes are online, the system keeps functioning normally.
Secret sharing is implemented via polynomial interpolation. A degree-(t-1) polynomial is generated with the private key as its constant term and the other coefficients chosen at random. Each participant receives the polynomial's value at a specific point as their share. Any t shares can reconstruct the original polynomial — and hence the private key — via Lagrange interpolation; fewer than t shares reveal no information about the private key at all.
During consensus, validator nodes sign messages with their own shares, producing signature shares. Once t signature shares have been collected, they're combined via Lagrange interpolation coefficients into a weighted aggregate, yielding the complete signature. This scheme achieves O(1) verification complexity while preserving security — a verifier only needs to verify the single aggregated signature, not each individual share signature.
2.4 Separating Consensus from Execution: The Power of Decoupling
Traditional blockchains tightly couple consensus and execution, so the two constrain each other. Consensus must wait for execution to finish before it can advance, while execution is in turn limited by consensus's serialization requirements. Bitroot breaks through this bottleneck by separating consensus from execution.
An asynchronous processing architecture is the foundation of this separation. The consensus module focuses on determining transaction order and reaching agreement quickly; the execution module processes transaction logic and state transitions in parallel in the background. The two communicate asynchronously via message queues — consensus results are passed to the execution module through a queue, and execution results are fed back to the consensus module the same way. This decoupled design lets consensus keep advancing continuously without waiting for execution to complete.
Resource isolation further optimizes performance. The consensus module and the execution module use independent resource pools, avoiding resource contention. The consensus module is equipped with high-speed network interfaces and dedicated CPU cores, focused on networking and message handling; the execution module is equipped with ample memory and multi-core processors, focused on compute-intensive state transitions. This specialization lets each module make full use of its hardware.
A batching mechanism amplifies the pipeline's effect. The leader node packages multiple block proposals into a batch and runs consensus on the batch as a whole. Batching amortizes the consensus overhead of k blocks, substantially lowering the average confirmation latency per block. At the same time, BLS signature aggregation pairs perfectly with batching — no matter how many blocks a batch contains, the aggregated signature size stays constant and verification time stays close to a constant.
2.5 Performance in Practice: From Theory to Reality
In a standardized test environment (AWS c5.2xlarge instances), Pipeline BFT delivers strong performance:
Latency: average latency is 300 milliseconds on a 5-node network, rising to only 400 milliseconds at 21 nodes — latency grows slowly with node count, confirming good scalability.
Throughput: the final test results reach 25,600 TPS, achieved through the combination of Pipeline BFT and state sharding.
Performance gains: compared to traditional BFT, latency drops 60% (1 second → 400 milliseconds), throughput rises 8x (3,200 → 25,600 TPS), and communication complexity is optimized from O(n²) to O(n²/D).
III. Optimistic Parallel EVM: Unlocking Multi-Core Compute Potential
3.1 The Historical Baggage of EVM Serialization
When the Ethereum Virtual Machine (EVM) was first designed, it adopted a global state-tree model for simplicity — every account and contract's state lives in a single state tree, and every transaction must execute strictly in sequence. That design was tolerable in blockchain's early days when applications were relatively simple, but as DeFi, NFTs, and other complex applications have grown, serialized execution has become a performance bottleneck.
State-access conflicts are the root cause of serialization. Even if two transactions touch completely unrelated accounts — Alice paying Bob, Charlie paying David — they must still be processed sequentially, because the EVM has no way to know in advance which state a transaction will touch, and so must conservatively assume any transaction could conflict, forcing sequential execution.
Dynamic dependencies make the problem worse. A smart contract can compute which addresses to access dynamically, based on its input parameters, so dependencies can't be determined at compile time. A proxy contract, for instance, might call different target contracts depending on user input, making its state-access pattern completely unpredictable ahead of execution. That makes static analysis nearly impossible, which in turn makes safe parallel execution impossible without further work.
The high cost of rollbacks makes optimistic parallelism difficult. If optimistic parallel execution turns out to have conflicted, all affected transactions must be rolled back. In the worst case, an entire batch has to be re-executed, wasting computation and badly hurting the user experience. Minimizing the scope and frequency of rollbacks while still guaranteeing safety is the central challenge of parallelizing the EVM.
3.2 Three-Stage Conflict Detection: Balancing Safety and Efficiency
Bitroot's three-stage conflict detection mechanism maximizes the efficiency of parallel execution while still guaranteeing safety. The three stages — before, during, and after execution — perform detection and verification respectively, building a multi-layered safety net.
Stage one: pre-execution screening lowers the probability of conflicts through static analysis. A dependency analyzer parses a transaction's bytecode to identify the state it may touch. For a standard ERC-20 transfer, it can precisely identify that the sender's and receiver's balances will be touched; for a complex DeFi contract, it can at least identify the main state-access patterns.
An improved counting Bloom filter (CBF) provides fast screening. A traditional Bloom filter only supports adding elements, not removing them. Bitroot's CBF maintains a counter for each slot, supporting dynamic addition and removal of elements. The CBF uses only 128KB of memory, relies on 4 independent hash functions, and keeps its false-positive rate under 0.1%. Using the CBF, the system can quickly determine whether two transactions might have a state-access conflict.
An intelligent grouping strategy organizes transactions into batches that can execute in parallel. The system models transactions as nodes in a graph, drawing an edge between two transactions if they might conflict. A greedy graph-coloring algorithm colors the graph, and transactions of the same color can safely run in parallel. This approach guarantees correctness while maximizing parallelism.
Stage two: in-execution monitoring performs dynamic detection while transactions are actually executing. Even after passing pre-execution screening, a transaction may still touch state outside what was predicted once it actually runs, so runtime conflict detection is still needed.
A fine-grained read/write lock mechanism provides concurrency control. Bitroot implements locks scoped to an address and storage slot, rather than a coarse contract-level lock. A read lock can be held by multiple threads simultaneously, allowing concurrent reads; a write lock can only be held by a single thread and excludes all read locks. This fine-grained locking maximizes parallelism while still guaranteeing safety.
Versioned state management implements optimistic concurrency control. Each state variable maintains a version number, and a transaction records the version of any state it reads while executing. Once execution finishes, the system checks whether the versions of everything it read are still unchanged. If a version number has changed, that indicates a read-write conflict, and the transaction must be rolled back and retried. This mechanism borrows from databases' multi-version concurrency control (MVCC), and works just as well in a blockchain setting.
Dynamic conflict handling uses a refined rollback strategy. When a conflict is detected, only the directly conflicting transaction is rolled back, not the entire batch. Through precise dependency analysis, the system can identify which transactions depend on the rolled-back one, minimizing the scope of the rollback. Rolled-back transactions rejoin the execution queue and run again in the next batch.
Stage three: post-execution verification ensures the final state is consistent. After all transactions in a batch have executed, the system performs a global consistency check. It computes the Merkle root hash of the state changes and compares it against the expected state root, confirming the correctness of the state transition. It also verifies version consistency across all state changes, ensuring no version conflicts were missed.
State merging uses a two-phase commit protocol to guarantee atomicity. In the prepare phase, every execution engine reports its results without committing; in the commit phase, once the coordinator confirms all results agree, it commits globally. If any execution engine reports a failure, the coordinator initiates a global rollback, guaranteeing state consistency. This mechanism borrows from the classic design of distributed transactions, ensuring the system's reliability.

3.3 Scheduling Optimizations: Keeping Every Core Busy
The payoff from parallel execution depends not just on the degree of parallelism, but on load balancing and resource utilization. Bitroot implements several scheduling optimizations to keep every CPU core running efficiently.
A work-stealing algorithm solves the problem of load imbalance. Each worker thread maintains its own double-ended queue, taking tasks from the head of the queue to execute. When a thread's queue is empty, it randomly picks a busy thread and "steals" a task from the tail of that thread's queue. This achieves dynamic load balancing, avoiding situations where some threads sit idle while others stay busy. Testing shows work-stealing raises CPU utilization from 68% to 90%, boosting overall throughput by roughly 22%.
NUMA-aware scheduling optimizes memory access patterns. Modern servers use non-uniform memory access (NUMA) architectures, where cross-NUMA-node memory access latency is 2-3x that of local access. Bitroot's scheduler detects the system's NUMA topology, pins worker threads to specific NUMA nodes, and prioritizes assigning tasks that access local memory. It also partitions state across NUMA nodes based on account-address hashes, so transactions touching a given account are preferentially scheduled onto the corresponding node. NUMA-aware scheduling cuts memory-access latency by 35% and raises throughput by 18%.
Dynamic parallelism adjustment adapts to different workloads. More parallelism isn't always better — too much parallelism intensifies lock contention and can actually hurt performance. Bitroot continuously monitors metrics like CPU utilization, memory bandwidth usage, and lock contention frequency, and dynamically adjusts the number of parallel execution threads. When CPU utilization is low and lock contention is mild, it increases parallelism; when lock contention is high, it reduces parallelism to ease contention. This adaptive mechanism lets the system automatically optimize its performance across different workloads.
3.4 Performance Breakthrough: Validated From Theory to Practice
In a standardized test environment, optimistic parallel EVM shows substantial performance gains:
Simple transfer scenario: throughput rises from 1,200 TPS to 8,700 TPS at 16 threads, a 7.25x speedup, with a conflict rate under 1%.
Complex contract scenario: DeFi contracts see a 5-10% conflict rate; even so, 16 threads still achieve 5,800 TPS, a 7.25x improvement over the serial baseline of 800 TPS.
AI compute scenario: with a conflict rate under 0.1%, throughput at 16 threads jumps from 600 TPS to 7,200 TPS, a 12x speedup.
Latency breakdown: end-to-end average latency is 1.2 seconds, made up of 600 milliseconds (50%) for parallel execution, 200 milliseconds (16.7%) for state merging, and 250 milliseconds (20.8%) for network propagation.
IV. State Sharding: The Ultimate Approach to Horizontal Scaling
4.1 State Sharding Architecture
State sharding is the core technology behind Bitroot's horizontal scaling, splitting blockchain state across multiple shards to enable parallel processing and storage.
Sharding strategy: Bitroot shards account state based on a hash of the account address, distributing accounts across different shards. Each shard maintains its own independent state tree, and a cross-shard communication protocol handles interaction between shards.
Shard coordination: a shard coordinator manages transaction routing and state synchronization between shards. The coordinator is responsible for decomposing cross-shard transactions into multiple sub-transactions, ensuring consistency across shards.
State synchronization: an efficient inter-shard state synchronization mechanism reduces synchronization overhead through incremental sync and checkpointing.
4.2 Cross-Shard Transaction Processing
Transaction routing: an intelligent routing algorithm routes transactions to the appropriate shard, reducing cross-shard communication overhead.
Atomicity guarantee: a two-phase commit protocol ensures cross-shard transactions are atomic — they either succeed entirely or fail entirely.
Conflict detection: a cross-shard conflict detection mechanism prevents state inconsistency between shards.
V. Performance Comparison and Scalability Validation
5.1 Comparison With Mainstream Blockchains
Confirmation time: Bitroot's 400-millisecond finality is on par with Solana, and far faster than Ethereum's 12 seconds and Arbitrum's 2-3 seconds, supporting real-time and high-frequency transactions.
Throughput: final test results reach 25,600 TPS, achieved through Pipeline BFT and state sharding while remaining fully EVM compatible.
Cost advantage: gas fees are just 1/10 to 1/50 of Ethereum's, on par with Layer 2 solutions, substantially improving application economics.
Ecosystem compatibility: full EVM compatibility guarantees zero-cost migration from the Ethereum ecosystem, letting developers enjoy high performance seamlessly.
5.2 Scalability Test Results

As blockchain technology continues to develop rapidly and its applications keep expanding, Bitroot's technical approach will offer an important reference and practical guide for the advancement of high-performance blockchains. We have good reason to believe that, in the not-too-distant future, high-performance blockchains will become essential infrastructure for the digital economy, providing strong technical support for humanity's digital transformation.
