overview of all requirements for production deployment. This includes critical
28+
blockers, performance requirements, and operational considerations for running
29+
the Mina Rust node on mainnet. See

# Mainnet Readiness
9+
10+
This document outlines the key features and improvements required for the Mina
11+
Rust node to be ready for mainnet deployment.
12+
13+
## Critical Requirements
14+
15+
### 1. Persistence Implementation
16+
17+
**Status**: Draft design
18+
([Issue #522](https://github.com/o1-labs/mina-rust/issues/522), see
19+
[persistence-design](persistence-design))
20+
21+
The ledger is currently kept entirely in memory, which is not sustainable for
22+
mainnet's scale. Persistence is required for:
23+
24+
- Reducing memory usage to handle mainnet-sized ledgers and amount of SNARKs
25+
- Enabling fast node restarts without full resync
26+
- Supporting webnodes with browser storage constraints
27+
- Providing a clean foundation for implementing SNARK verification deduplication
28+
29+
**Note**: There is a very old implementation for on-disk storage in
30+
`ledger/src/ondisk` that was never used - a lightweight key-value store
31+
implemented to avoid the RocksDB dependency. This is unrelated to the new
32+
persistence design which intends to solve persistence for everything, not just
33+
the ledger. But the old implementation may be worth revisiting anyway.
34+
35+
**Performance Impact**: The importance of SNARK verification deduplication for
36+
mainnet performance has been demonstrated in the OCaml node, where we achieved
37+
dramatic improvements (8-14 seconds → 0.015 seconds for block application). See
38+
the "SNARK Verification Deduplication" section in
39+
[persistence-design](persistence-design) for details.
40+
41+
### 2. Wide Merkle Queries
42+
43+
**Status**: Not implemented
44+
([Issue #1086](https://github.com/o1-labs/mina-rust/issues/1086))
45+
46+
Wide merkle queries are needed for:
47+
48+
- Protocol compatibility
49+
- Faster synchronization
50+
51+
### 3. Delta Chain Proof Verification
52+
53+
**Status**: Not implemented
54+
([Issue #1017](https://github.com/o1-labs/mina-rust/issues/1017))
55+
56+
When verifying blocks, the Mina Rust node should verify the delta chain proofs.
57+
58+
### 4. Automatic Hardfork Handling
59+
60+
**Status**: Not implemented
61+
62+
The Mina Rust node needs a mechanism to automatically handle protocol hardforks
63+
to maintain compatibility with the network as it evolves.
64+
65+
**Requirements**:
66+
67+
- Detection of hardfork activation points
68+
- Automatic protocol rule updates
69+
- Backward compatibility during transition periods
70+
- Clear migration paths for node operators
71+
72+
### 5. Archive Node Functionality
73+
74+
**Status**: Partially implemented
75+
76+
For full mainnet support, robust archive functionality is essential:
77+
78+
- **Block Storage**: Persistent storage of all blocks and transactions
79+
- **Query Interface**: Efficient querying of historical data
80+
- **Data Integrity**: Verification of archived data consistency
81+
- **Reorg Handling**: Proper handling of blockchain reorganizations
82+
83+
### 6. Performance Optimization
84+
85+
**Status**: Ongoing
86+
87+
Several performance optimizations are critical for mainnet scale:
88+
89+
#### SNARK Pool Management
90+
91+
- Efficient pruning of outdated SNARK work
92+
- Memory-efficient pool storage
93+
- Fast lookup and retrieval mechanisms
94+
95+
#### Network Efficiency
96+
97+
- Optimized peer discovery and connection management
98+
- Bandwidth usage optimization
99+
- Connection pooling and reuse
100+
101+
#### Block Processing
102+
103+
- Parallel transaction verification where possible
104+
- Optimized state transitions
105+
- Efficient memory usage during processing
106+
107+
### 7. Monitoring and Observability
108+
109+
**Status**: Basic implementation
110+
111+
Production deployment requires comprehensive monitoring:
112+
113+
- **Metrics Collection**: Key performance indicators and health metrics
114+
- **Logging**: Structured logging for debugging and analysis
115+
- **Alerting**: Automated alerts for critical issues
116+
- **Dashboard Integration**: Integration with monitoring dashboards
117+
118+

205+
206+
## Risk Assessment
207+
208+
### High Risk Areas
209+
210+
- **Persistence Implementation**: Complex system with potential for data
211+
corruption
212+
- **Performance Under Load**: Untested behavior under mainnet scale
213+
- **Protocol Compatibility**: Risk of consensus failures if implementation
214+
differs
215+
216+
### Mitigation Strategies
217+
218+
- **Extensive Testing**: Comprehensive test suites for all critical
219+
functionality
220+
- **Gradual Rollout**: Phased deployment starting with testnets
221+
- **Monitoring**: Real-time monitoring to detect issues early
222+
- **Fallback Plans**: Clear procedures for rollback if issues arise
223+
224+
## Timeline Considerations
225+
226+
The mainnet readiness timeline depends on:
227+
228+
- **Development Resources**: Available engineering capacity
229+
- **Testing Requirements**: Time needed for comprehensive validation
230+
- **Network Coordination**: Alignment with broader Mina ecosystem timeline
231+
- **Performance Validation**: Real-world testing and optimization
232+
233+
Priority should be given to persistence implementation as it's foundational for
234+
most other mainnet readiness requirements and represents the largest technical
235+
risk.
236+
237+
## Community and Ecosystem
238+
239+
### Node Operator Support
240+
241+
- **Documentation**: Comprehensive deployment and operational guides
242+
- **Support Channels**: Clear support and communication channels
243+
- **Migration Tools**: Tools to help migrate from OCaml nodes if desired
244+
245+
### Developer Integration
246+
247+
- **API Compatibility**: Maintain compatibility with existing tooling
248+
- **Extension Points**: Allow for ecosystem development and integration
249+
- **Developer Tools**: Provide tools for developers building on Mina
250+
251+
## Conclusion
252+
253+
Mainnet readiness for the Mina Rust node requires careful implementation of
254+
critical features, extensive testing, and operational preparation. The
255+
persistence implementation represents the most significant technical challenge
256+
and should be prioritized accordingly.
257+
258+
Success will be measured not just by technical compliance, but by the node's
259+
ability to operate reliably in production environments and contribute to the
260+
overall health and decentralization of the Mina network.
