Overview

Parameters that uniquely affect validators of the Allora Chain

Consensus parameters control the fundamental operational characteristics of the Allora blockchain network. These parameters define block properties, evidence handling, and validator requirements that are essential for network security, performance, and reliability.

Why Consensus Parameters Matter

Network Performance:

Throughput control: Block size and gas limits determine transaction processing capacity
Resource management: Parameters prevent network congestion and excessive resource usage
Predictable operation: Consistent parameters enable reliable network performance
Scalability planning: Parameters can be adjusted to support network growth

Security and Integrity:

Evidence validation: Parameters ensure proper handling of validator misbehavior evidence
Network protection: Limits prevent abuse and maintain network stability
Validator standards: Requirements ensure all validators meet security specifications
Consensus reliability: Parameters support robust consensus mechanism operation

Block Configuration

Block Size Management

block.max_bytes

Sets the maximum size of a block in bytes.

Value: 22020096

Standard value.
This parameter limits the block size, preventing excessive network load. However, setting it too low may restrict the number of transactions in a block. The current value strikes a balance between controlling block size and allowing for sufficient transaction throughput.

Block Size Strategy:

Network efficiency: Prevent blocks from becoming too large for efficient network propagation
Transaction capacity: Allow adequate space for meaningful transaction volume
Resource balance: Balance between network performance and transaction throughput
Propagation time: Ensure blocks can be transmitted quickly across the network

Performance Implications:

Network bandwidth: Larger blocks require more bandwidth for propagation
Validation time: Bigger blocks take longer to validate and process
Storage requirements: Block size affects long-term storage needs
Sync performance: Impacts initial sync time for new nodes

Gas Limit Configuration

block.max_gas

Sets the maximum amount of gas that can be used in a block.

Value: -1

Standard value.
The current setting allows for flexibility by indicating no limit on the maximum gas usage in a block. While this offers freedom for transactions, careful monitoring is needed to prevent potential abuse. This approach acknowledges the need for adaptability in a dynamic network environment.

Gas Limit Strategy:

Unlimited flexibility: No hard cap allows for adaptive gas usage based on network needs
Market-driven: Gas prices naturally limit excessive usage through economic incentives
Network evolution: Allows network to adapt to changing computational requirements
Performance monitoring: Requires ongoing observation to prevent abuse

Operational Considerations:

Abuse prevention: Monitor for excessive gas usage that could slow the network
Economic balance: Rely on gas pricing to manage computational resource usage
Network health: Track block processing times and validator performance
Future planning: May need to implement limits based on network growth

Evidence Management

Evidence Age Limits

evidence.max_age_num_blocks

Sets the maximum age (in blocks) of evidence that can be included in a block.

Value: 100000

Standard value.
By limiting the age of evidence, this parameter maintains network security by preventing the inclusion of outdated evidence. The chosen value strikes a reasonable balance between retaining relevant evidence and ensuring integrity of the network.

Block-Based Age Control:

Relevance maintenance: Ensure evidence remains relevant to current network state
Security focus: Prevent old evidence from being used inappropriately
Network integrity: Maintain consistency in evidence validation across time
Storage efficiency: Limit retention of outdated information

evidence.max_age_duration

Sets the maximum age (in nanoseconds) of evidence that can be included in a block.

Value: 172800000000000

Standard value.
This parameter complements max_age_num_blocks by providing an additional measure to limit the inclusion of outdated evidence. The current setting aligns with the need for a comprehensive yet controlled approach to evidence inclusion.

Time-Based Age Control:

Dual protection: Works with block-based limits for comprehensive age management
Temporal relevance: Ensure evidence remains temporally relevant
Cross-validation: Provide multiple mechanisms for evidence age verification
System robustness: Multiple age checks improve overall system reliability

Duration Analysis:

Nanosecond precision: High precision timing for accurate age calculation
48-hour window: Approximately 48 hours (172,800 seconds) maximum age
Reasonable timeframe: Sufficient time for evidence collection and validation
Security balance: Balance between evidence utility and staleness prevention

Evidence Size Control

evidence.max_bytes

Sets the maximum size of evidence in bytes.

Value: 1048576

Standard value.
Controlling the size of evidence prevents potential abuse and ensures efficient network operation. While too low a value may restrict the inclusion of legitimate evidence, the current setting finds a suitable compromise between limiting size and maintaining the effectiveness of the evidence mechanism.

Size Management Benefits:

Network efficiency: Prevent large evidence from slowing block processing
Storage optimization: Control blockchain storage requirements
Abuse prevention: Limit potential for evidence spam or DoS attacks
Processing speed: Ensure evidence can be validated quickly

Size Specifications:

1MB limit: 1,048,576 bytes maximum evidence size
Reasonable capacity: Sufficient space for comprehensive evidence data
Performance balance: Large enough for effectiveness, small enough for efficiency
System scalability: Manageable size for long-term network growth
