1. Introduction
Proof of Work (PoW) blockchain systems like Bitcoin rely on mining for security, but miners face revenue instability due to the exponential distribution of block generation times. The expected time until receiving a block reward is $T/\alpha$, with variance $T^2/\alpha^2$, where $\alpha$ is the miner's hashrate ratio and $T$ is the average block generation interval. This creates significant revenue volatility for small miners.
2. Related Work
2.1 Centralized Mining Pools
Traditional mining pools centralize hashrate, undermining blockchain decentralization principles and creating single points of failure.
2.2 P2Pool
The first decentralized mining pool using a share chain sidechain. Faces scalability limitations and security vulnerabilities during early stages when hashrate is low.
2.3 Smart Pool
Uses main chain smart contracts with probabilistic verification via Merkle trees. Suffers from high fees and budget imbalance due to Pay-Per-Share payment scheme.
3. FIBER POOL Architecture
3.1 Three-Chain Design
FIBER POOL employs three interconnected blockchains: main chain smart contract for governance, storage chain for share data, and child chain for fee-efficient reward distribution.
3.2 Share Verification
Local share verification by miners reduces main chain congestion. Storage chain enables efficient data sharing while maintaining security.
3.3 Payment Scheme
FIBER POOL Proportional scheme ensures budget balance and incentive compatibility while maintaining reward stability.
4. Technical Implementation
4.1 Mathematical Foundation
The probability of a miner finding a block follows Poisson distribution with parameter $\lambda = \alpha/T$. The share verification uses cryptographic hashing: $H(share) < target_{share}$ where $target_{share} > target_{block}$.
4.2 Code Implementation
class FiberPool:
def __init__(self, main_chain, storage_chain, child_chain):
self.main_contract = main_chain
self.storage = storage_chain
self.child = child_chain
def submit_share(self, share, proof):
# Local verification first
if self.verify_share_locally(share, proof):
self.storage.store_share(share)
return True
return False
def verify_share_locally(self, share, proof):
return hash(share + proof) < SHARE_TARGET5. Experimental Results
Testing shows FIBER POOL reduces fees by 68% compared to Smart Pool while maintaining security. The three-chain architecture demonstrates linear scalability with increasing miner participation.
6. Future Applications
FIBER POOL's architecture can extend to decentralized finance (DeFi) applications, cross-chain asset transfers, and multi-chain governance systems. The child chain concept aligns with Ethereum's layer-2 scaling solutions.

8. Critical Analysis
一针见血：FIBER POOL本质上是在区块链不可能三角（去中心化、安全性、可扩展性）中寻找新的平衡点，但三链架构的复杂性可能成为 adoption 的最大障碍。
逻辑链条：从中心化矿池→P2Pool→Smart Pool→FIBER POOL，技术演进的核心矛盾始终是『如何在保持去中心化的前提下降低交易成本』。FIBER POOL通过将验证工作下放到本地、数据存储与结算分离，确实在理论上突破了前两代的瓶颈。但正如以太坊从PoW转向PoS所证明的，架构复杂性往往与安全风险成正比。
亮点与槽点：最大的亮点在于三链分工的设计思想——这比单纯的侧链或状态通道更精细。存储链专门处理数据验证，子链专注小额交易，主链负责最终结算，这种『专业分工』模式在微软研究院的区块链分层研究中也有类似论述。但槽点也很明显：初期启动需要足够的算力支撑存储链安全，这恰恰是大多数新项目死亡的陷阱。另外，论文中提到的『本地验证』虽然节省费用，但可能引入女巫攻击漏洞，这在Tor网络和早期BitTorrent系统中都有过惨痛教训。
行动启示：对于投资者，应该关注团队是否具备跨链开发经验（如Cosmos/Polkadot背景）。对于开发者，可以优先实现与现有矿池的兼容接口来降低迁移成本。对于研究者，需要进一步验证其支付方案在博弈论层面的稳健性——毕竟Mt. Gox的崩溃提醒我们，再好的技术也抵不过经济模型的缺陷。
