High-level design of Buburuza blockchain
Buburuza is designed to deliver high transaction throughput, strong security, and developer compatibility, while optimizing for enterprise use. Below is an overview of its architecture, principles, and how its components work together.
Purpose & Key Motivations
Scalability: Overcome the limitations of base Layer-1 networks (low TPS, high gas fees) by moving execution off chain yet anchoring security to a more secure base layer.
Cost Efficiency: Significantly reduce transaction costs via batching, compression, and efficient data availability.
Security: Ensure that even though execution is faster and cheaper, the security guarantees are not compromised. Fraud detection, validation, and anchoring to a secure base layer preserve trust.
Developer Ecosystem Compatibility: Support existing tools, smart contract languages (Solidity/Vyper), wallets, and EVM standards so developers can use familiar tooling with minimal friction.
Core Architectural Principles
Optimistic Rollup Model Buburuza operates under an optimistic rollup paradigm: transactions are proposed and accepted under the assumption they're valid, with mechanisms in place so that any invalid or fraudulent transaction can be challenged. This offers efficiency while preserving trust.
Sequencing then Deterministic Execution
Sequencer: Orders transactions, batches them, and submits the batch information to the base layer (Layer-2).
Deterministic State Transition Function: Once transactions are sequenced, execution is deterministic — every node using the same state and input will produce the same output.
Separation of Concerns Different system components have well-defined roles:
Execution (processing transactions, smart contracts)
Validation / Fraud Proving (disputes, checking correctness)
Settlement (anchoring data, finalizing state)
Data Availability & Compression Transactions and state data are made available so that anyone can verify or reconstruct the state. Data is compressed (where possible) when posted to the base chain to save space/costs, but full detail is preserved off-chain / in rollup for verification.
Security Guarantees
Fraud Proofs & Interactive Challenges: If there’s a disagreement (e.g. invalid batch), validators/provers can challenge. The dispute resolution mechanism narrows down what is wrong and resolves it, leveraging the base chain for the final judgment.
Trust Assumption: Even if only one honest validator remains, fraud can still be detected & bad behavior corrected. This protects users.
Anchoring to Base Layer: Because state/data is ultimately anchored to the base chain, Buburuza inherits a strong, decentralized security foundation.
EVM-compatible codebase: Supporting existing smart contract tools helps reduce risk (because many existing patterns and auditing wisdom apply directly).
Efficiency & Cost Optimizations
Batching many transactions together into one base-layer submission to amortize cost.
Data compression where possible when posting to base chain (compressed proofs, succinct state commitments) while preserving the ability to verify.
Reduced overhead by avoiding redundant base-chain operations for every transaction.
Predictable gas model to help enterprise users budget and plan.
Differentiators / Adaptations for Buburuza
While much of Buburuza’s design mirrors concepts proven in rollup systems, here are how you might adapt or emphasize certain choices:
Using an L3 rollup variant: Buburuza adds an extra layer (L3) to allow more flexibility in enterprise customizations, fee adjustments, or private/semi-private deployments without burdening the base rollup.
Native BUBU token for all gas / utility interactions.
Optional features like fast exit bridges, or delegated sequencing/fallback sequencers for reliability.
Focus on enterprise use: compliance, auditability, API access, SLA-style performance, etc.
