Utangulizi na Muhtasari
BlockReduce inatoa muundo mpya wa mnyororo wa kuzuia unaojengwa kwa uthibitisho wa kazi (PoW), unaolenga kushinda vikwazo vya msingi vya uwezo wa usindikaji katika mifumo ya jadi kama vile Bitcoin na Ethereum. Uvumbuzi wake mkuu ni kutumia muundo wa safu za mnyororo wa kuzuia unaochimbwa kwa pamoja na kufanya kazi sambamba, na kufanya uwezo wa usindikaji wa manunuzi uweze kupanuka zaidi ya mstari kulingana na idadi ya minyororo. Njia hii, huku ikidumisha modeli thabiti ya usalama ya PoW, inashughulikia maswala ya ucheleweshaji wa mtandao na kuzingatia thamani ya manunuzi.

Muundo Mkuu na Mfumo wa Teknolojia
The BlockReduce system architecture is built upon three fundamental pillars that work in concert to achieve scalability without compromising the decentralized security of Proof-of-Work.
2.1 Hierarchical Blockchain Structure
BlockReduce organizes network nodes into a tree-like hierarchical structure based on network latency measurements. Each cluster or sub-network runs its own blockchain, validating a specific partition of the overall application state. This structure directly addresses the network propagation delay, which is considered a primary bottleneck in traditional blockchains.
Muundo huu wa ngazi unafuata uhusiano wa mzazi na mtoto:
- Mnyororo mzizi unaratibu mfumo mzima
- Mid-chain handles regional transactions
- Leaf-chain handles local, low-latency transactions
2.2 Merged Mining Mechanism
Unlike traditional sidechain or sharding approaches, BlockReduce applies the entire network's computational power to all chains simultaneously through merged mining. Miners can process multiple chains in parallel, and their computational work contributes to the security of the entire hierarchy.
This method eliminates the security fragmentation issue common in sharding systems, where individual shards become vulnerable to 51% attacks due to reduced computational power.
2.3 Transaction Dependency Security Model
BlockReduce introduces a revolutionary concept: security is proportional to transaction value. High-value transactions require confirmation at higher levels in the hierarchy (more cumulative work), while low-value transactions can be confirmed quickly at lower levels.
This model mirrors real-world financial systems:
- Ununuzi mdogo unahitaji uthibitishaji mdogo zaidi
- Uhamisho mkubwa unahitaji ukaguzi mwingi wa usalama
- Kuthibitisha uthabiti wa mwisho kupitia usawazishaji wa ngazi.
3. Layered Longest Chain Rule
Utaratibu huu wa makubaliano unapanua kanuni ya mnyororo mrefu zaidi ya Bitcoin kwa mazingira ya ngazi, na kuunda dhana ya "uzito" wa mnyororo wa pande nyingi unaojumuisha urefu wa mnyororo na nafasi ya ngazi.
3.1 Mathematical Formulation
Uzito wa makubaliano wa ngazi $W(C_i)$ wa mnyororo $C_i$ kwenye ngazi $l$ umebainishwa kama:
$W(C_i) = \alpha \cdot L(C_i) + \beta \cdot \sum_{j \in children(C_i)} W(C_j) + \gamma \cdot S(C_i)$
Ambapo:
- $L(C_i)$: Urefu wa mnyororo $C_i$
- $children(C_i)$: Seti ya vijanyororo
- $S(C_i)$: Thamani ya jumla ya manunuzi iliyolindwa
- $\alpha, \beta, \gamma$: weighting parameters
3.2 Cross-Chain State Transition
Cross-blockchain transactions are realized through a hierarchical commitment scheme. Transactions initiated on a leaf chain can be "lifted" to a parent chain for additional security, and the hierarchical structure ensures cross-chain atomicity.
Itifaki hiyo inahakikisha kwamba kwa miamala yoyote ya kuvuka mnyororo $T$:
$\forall C_i, C_j \in \text{Hierarchy}, \text{Commit}(T, C_i) \Rightarrow \text{Commit}(T, C_j)$
Hii inazuia mashambulizi ya matumizi-maradu ya mnyororo tofauti katika muundo wa ngazi.
4. Performance Analysis and Results
4.1 Throughput Scaling Analysis
Uchambuzi wa kinadharia unaonyesha kuwa BlockReduce inafikia upanuzi wa uzalishaji wa hali ya juu. Wakati kuna minyororo $n$ sambamba katika muundo wa ngazi, upanuzi wa uzalishaji $T(n)$ ni:
$T(n) = O(n \cdot \log n)$
Hii inawakilisha uboreshaji wa kimsingi ukilinganisha na mbinu za upanuzi wa mstari, shukrani kwa uratibu wa ngazi uliopunguza mzigo wa mawasiliano kwenye minyororo mbalimbali.
Matokeo ya uigaji yanaonyesha:
- Minyororo 10: Uzalishaji ulioboreshwa kwa 150% ukilinganisha na kiwango cha msingi
- 100 chains: throughput increased by 850%
- 1000 chains: throughput increased by 6800%
4.2 Uhakikisho wa Usalama
Uchambuzi wa usalama unaonyesha kuwa BlockReduce inadumisha usalama wa kiwango cha Bitcoin kwa manunuzi ya thamani kubwa, huku ikifanikisha malipo ya haraka kwa manunuzi ya thamani ndogo. Kwa thamani ya manunuzi $V$, uwezekano wa shambulio la matumizi-maradufu $P_{attack}$ umepakana na:
$P_{attack}(V) \leq e^{-\lambda \cdot f(V) \cdot t}$
Ambapo $f(V)$ ni kitendakazi cha kuongezeka kwa monotonic cha thamani ya biashara, na $\lambda$ inawakilisha jumla ya kiwango cha hash cha mtandao.
5. Core Insights and Analysis
Ufahamu wa Msingi
Uvumbuzi wa msingi wa BlockReduce sio tu minyororo sambamba, bali ni utaratibu wa ushirikiano wa ngazi unaofanya usambamba ufanye kazi bila kutawanya usalama. Karatasi hiyo inasema kwa usahihi kwamba mgawanyiko rahisi unashindwa kwa sababu hupunguza usalama wa PoW, lakini njia yake ya uchimbaji wa madini ya ngazi inashikilia nguvu ya mtandao kwenye minyororo yote. Hii ndiyo suluhisho la kwanza la upanuzi la PoW niliyoona ambalo halitoi usalama kwa ajili ya uwezo wa usafirishaji.
Mfuatano wa Mantiki
Mchakato wa uthibitisho ni mzuri sana: (1) Ucheleweshaji wa mtandao ndio kikwazo halisi, sio hesabu → (2) Makundi yanayotegemea ucheleweshaji huunda mgawanyiko wa asili → (3) Uchimbaji wa madini uliochanganyika huhifadhi usalama kwenye migawanyiko → (4) Muundo wa ngazi unafanikisha uratibu bora kwenye migawanyiko. Hii inashughulikia mgogoro wa msingi katika shida tatu ya blockchain kwa ufanisi zaidi kuliko mpango wa Ethereum unaozingatia Rollup au njia ya monolithi ya Solana.
Faida na Upungufu
Faida: Muundo wa usalama unaotegemea muamala ni bora sana — unatambua kwamba sio muamala wote unahitaji ukweli wa mwisho wa kiwango cha Bitcoin. Muundo wa ngazi unashughulikia kwa ustadi muamala wa kuvuka mnyororo, tofauti na mnyororo mkuu tata wa Polkadot au mzigo wa IBC wa Cosmos. Madai ya upanuzi wa zaidi ya mstari, ingawa ni ya kinadharia, ni ya kuaminika kihisabati.
Upungufu: Karatasi ilidharau utata wa utekelezaji. Ushirikiano wa ngazi unahitaji programu tata za nodi ambazo hazijapatikana kwa sasa. Dhana ya nguzo kulingana na ucheleweshaji inadhani hali ya mtandao ni thabiti—kutofautiana kwa mtandao wa ulimwengu halisi kunaweza kusababisha upyaaji wa mnyororo mara kwa mara. Zaidi ya hayo, hakuna mjadala juu ya uthabiti wa motisha kuvuka ngazi.
Ufahamu unaoweza kutekelezwa
Biashara zinapaswa kuanzisha wazo la BlockReduce katika mnyororo wa ushirika wa kibinafsi unaodhibitiwa ucheleweshaji. Wasanidi programu wanapaswa kulenga ujenzi wa miundombinu ya programu za nodi—hapa ndipo fursa halisi iko. Wawekezaji wanapaswa kuzingatia timu zinazotekeleza ushirikiano wa ngazi, kwani hii inaweza kuwa mfano mkuu wa upanuzi baada ya muunganiko wa Ethereum. Wadhibiti wanapaswa kuzingatia muundo wa usalama unaotegemea muamala—unauunda ngazi asilia ya kufuata kanuni kwa aina tofauti za manunuzi.
6. Technical Details and Mathematical Framework
The hierarchical consensus protocol is formalized through several key mathematical structures:
6.1 Chain Weight Calculation
The weight function $W$ used for chain validation encompasses multiple dimensions:
$W(C, t) = \int_0^t w(s) \cdot h(C, s) \, ds + \sum_{P \in parents(C)} \rho(P, C) \cdot W(P, t)$
Ambapo $w(s)$ ni kitendakazi cha kufifia kwa wakati, na $h(C, s)$ ni kiwango cha hashi kinachotumika kwa mnyororo $C$ kwa wakati $s$.
6.2 Usalama wa Kigeuzi
Kiwango cha usalama $\sigma(V)$ cha thamani ya biashara $V$ hufuata:
$\sigma(V) = \sigma_{min} + (\sigma_{max} - \sigma_{min}) \cdot \frac{\log(1 + V/V_0)}{\log(1 + V_{max}/V_0)}$
Ubadilishaji huu wa logarithimu unahakikisha mpito laini kati ya viwango vya usalama.
6.3 Uboreshaji wa Uzalishaji
Kwa ukubwa wa mtandao $N$ na usambazaji wa ucheleweshaji $L$, kina bora cha ngazi $d^*$ ni:
$d^* = \arg\max_d \left[ \frac{N}{\bar{b}^d} \cdot \left(1 - \frac{L_{inter}}{L_{intra}}\right)^d \right]$
Ambapo $\bar{b}$ ni sababu ya tawi ya wastani, $L_{inter}$ ni ucheleweshaji kati ya makundi, na $L_{intra}$ ni ucheleweshaji ndani ya kundi.
7. Experimental Results and Validation
The paper provides simulation results to validate the theoretical claims.
7.1 Throughput Scaling Results
Figure 1 demonstrates superlinear scaling with an increasing number of chains. The experimental setup used 1000 nodes and was based on a real Internet latency distribution (based on CAIDA Ark measurements). The results show:
- Itifaki ya msingi ya Bitcoin: TPS 7
- BlockReduce (minyororo 10): TPS 18 (ongezeko la 157%)
- BlockReduce (100 chains): 95 TPS (increase 1257%)
- BlockReduce (1000 chains): 850 TPS (increase 12042%)
7.2 Latency Impact Analysis
Kielelezo 2 kinaonyesha muda wa uthibitishaji wa manunuzi kama utendakazi wa ngazi na thamani ya manunuzi. Ugunduzi mkuu:
- 低价值交易（< $10）：在叶链上 2 秒确认
- 高价值交易（> $10,000）：需要根链包含，10 分钟确认
- Cross-chain transactions: Incur an additional 30% latency overhead compared to on-chain transactions
7.3 Security Verification
Kielelezo 3 kinaonyesha uwezekano wa mafanikio ya shambulio la matumizi-maradufu chini ya mifano tofauti ya mpinzani. Hata kwa kiwango cha 40% cha jumla ya kiwango cha hash, kwa manunuzi ya thamani kubwa, baada ya uthibitisho wa mara 6, uwezekano wa mafanikio ya shambulio bado ni chini ya $10^{-6}$.
