2 1 Introduction

The Electroneum Smart Chain has been a cornerstone of the Electroneum

ecosystem, providing a robust and efficient blockchain infrastructure for decen-

tralised applications and digital asset management. As the blockchain landscape

continues to evolve, it is crucial that we adapt and enhance our technology to

meet the growing demands of our users and maintain our competitive edge in

the market.

This proposal outlines a comprehensive update to the Electroneum blockchain,

focusing on improving decentralisation, resilience, and governance. The pro-

posed changes aim to address several key areas:

1. Decentralisation: By transitioning to a permissionless validator sys-

tem, we aim to increase the diversity and distribution of network valida-

tors, enhancing the overall security and trustlessness of the Electroneum

Blockchain.

1. Resilience: The introduction of a fallback mechanism at the consensus

level will significantly improve the network’s ability to maintain operations

in the face of validator failures or malicious behaviour.

1. Governance: Implementing on-chain governance features will empower

our community to participate more directly in the decision-making pro-

cesses that shape the future of the Electroneum Blockchain.

1. Transparency: By adopting industry-standard smart contracts for val-

idator management and metadata, we will increase the visibility and au-

ditability of network operations.

1. Usability: Enhanced RPC and command-line interfaces will make it eas-

ier for developers and users to interact with the new validator system and

governance features.

These updates represent a significant step forward for the Electroneum

Smart Chain, aligning our technology with best practices in the blockchain in-

dustry while maintaining the unique features that make Electroneum Blockchain

valuable to our users.

2 Background

2.1 Current Electroneum Smart Chain Architecture

The Electroneum Smart Chain currently operates on a permissioned IBFT (Is-

tanbul Byzantine Fault Tolerance) consensus mechanism. This system relies on

a predetermined set of validator nodes, each taking turns to propose and vali-

date blocks in a round-robin fashion. The current architecture has served Elec-

troneum Blockchain well, providing fast transaction finality and high through-

put. However, as the blockchain ecosystem evolves, certain limitations have

become apparent.

3 2.2 Limitations of the Current System

1. Limited Participation: The current system restricts broader commu-

nity involvement in network security and governance.

1. Scalability Challenges: As the network grows, the static validator set

may become a bottleneck for scalability and global distribution.

1. Lack of Economic Incentives: Without a validator warrant mecha-

nism, there are limited economic incentives for validators to act in the

network’s best interests.

1. Governance Constraints: The absence of on-chain governance mecha-

nisms limits the community’s ability to participate in protocol-level decision-

making.

Addressing these limitations is crucial for the long-term sustainability and

growth of the Electroneum Smart Chain. The proposed updates outlined in

this whitepaper are designed to overcome these challenges while preserving the

strengths of the current system.

3 Proposed Updates

3.1 Permissionless Validator System

The cornerstone of the Electroneum Blockchain update is the transition to a

permissionless validator system. This new model allows any participant to pro-

pose themselves as a validator candidate by locking a specified amount of ETN

tokens. Key features include:

• Open validator registration through Candidate Registration Transactions

(CRT).

• Community support for validators via Candidate Support Transactions

(CST).

• Dynamic validator set selection based on warrant amounts and community

support.

• Penalty mechanisms for misbehaving or underperforming validators.

This system democratizes network participation while maintaining high stan-

dards for validator performance and security.

3.2 Enhanced Consensus Mechanism

The proposed update introduces significant enhancements to the existing IBFT

consensus mechanism, focusing on improved resilience, scalability, and security.

These changes are designed to work in tandem with the new permissionless

validator system.

4 3.2.1 Dynamic Validator Set

The enhanced consensus mechanism will support a dynamic validator set, al-

lowing for:

• Flexible Validator Count: The number of active validators can be

adjusted based on network needs, with an initial target of 24 validators.

• Epoch-based Rotation: Validator sets will be updated at the end of

each epoch (17,280 blocks or approximately 1 day), based on warrant

amount, performance, and community support.

• Smooth Transitions: The mechanism ensures seamless transitions be-

tween validator sets without disrupting network operations.

3.2.2 Fallback Mechanism

To address potential issues with unresponsive or malicious validators, a fallback

mechanism is introduced:

• Real-time Monitoring: The system continuously monitors validator

performance within each epoch at consensus level.

• Failure Detection: Identifies validators that consistently fail to propose

or sign blocks within the specified timeframe.

• Penalty System: Validators that trigger the fallback mechanism are

subject to penalties, including potential removal from the active set and

slashing of warrant tokens.

3.2.3 Security Enhancements

Several security improvements are incorporated into the new consensus mecha-

nism:

• Byzantine Fault Tolerance: Maintains IBFT’s ability to tolerate up to

1/3 of validators being malicious or faulty.

• Warrant-Weighted Voting: Introduces warrant-weighted voting for

consensus decisions, aligning economic incentives with network security.

3.2.4 Interoperability Considerations

To ensure broad compatibility and future-proofing:

• EVM Compatibility: Maintains full compatibility with the Ethereum

Virtual Machine, ensuring seamless operation of existing smart contracts

and easy migration of Ethereum-based dApps.

5 • Cross-Chain Support: Lays the groundwork for future cross-chain in-

teroperability features, potentially allowing for communication with other

blockchain networks.

This enhanced consensus mechanism represents a significant leap forward in

the capabilities and resilience of the Electroneum Smart Chain. By combin-

ing the strengths of IBFT with dynamic validator selection, advanced security

features, and scalability optimisations, Electroneum Blockchain is positioned to

meet the demands of a growing and diverse blockchain ecosystem.

3.3 On-Chain Governance

The introduction of on-chain governance is a crucial step towards decentralising

decision-making and empowering the Electroneum community. This system

allows stakeholders to propose, discuss, and vote on changes to the network

parameters and protocol upgrades.

3.3.1 Governance Framework

The on-chain governance system is built on the following principles:

• Transparency: All proposals and voting processes are publicly visible on

the blockchain.

• Inclusivity: Any ETN holder can participate in the governance process.

• Security: Robust mechanisms to prevent malicious proposals or voting

manipulation.

• Flexibility: The ability to govern a wide range of network parameters

and protocol changes.

3.3.2 Proposal Mechanism

The governance system introduces a structured proposal process:

1. Proposal Submission:

• Any address holding a minimum threshold of ETN (to be determined)

can submit a proposal.

• Proposals are submitted as transactions to a dedicated Governance

Smart Contract (GSC).

• Each proposal includes a description, the proposed change, and an

execution timeframe.

1. Proposal Types:

6 • Parameter Changes: Adjustments to network parameters such as

minimum validator warrant amount, block gas limit, or transaction

fees.

• Protocol Upgrades: Major changes to the blockchain protocol, includ-

ing consensus mechanism updates.

• Fund Allocation: Decisions on the use of community funds or treasury

allocations.

• Validator Management: Proposals to blacklist malicious validators

or adjust validator selection criteria.

1. Discussion Period:

• Each proposal has a designated discussion period (e.g. 7 days) for

community debate.

• An off-chain forum will be provided for detailed discussions, with key

points summarised on-chain.

3.3.3 Voting System

The voting mechanism is designed to be fair, secure, and resistant to manipu-

lation:

1. Eligibility:

• All ETN holders are eligible to vote.

• Voting power is proportional to the amount of ETN held or war-

ranted.

1. Voting Process:

• Votes are cast by sending a transaction to the GSC.

• Options include ”Yes”, ”No”, and ”Abstain”.

• Votes can be changed until the voting period ends.

1. Quorum and Majority:

• A minimum quorum (e.g. 10% of circulating ETN) must participate

for a vote to be valid.

• Proposals require a supermajority (e.g. 66%) to pass.

1. Voting Period:

• Standard voting period of 14 days, adjustable for urgent proposals.

1. Vote Locking:

• ETN used for voting is locked until the end of the voting period to

prevent double voting.

7 3.3.4 Execution of Approved Proposals

Once a proposal is approved:

1. Time lock: A time lock period (e.g. 48 hours) is initiated before changes

take effect.

1. Automated Execution: For parameter changes, the GSC automatically

applies the update after the time lock.

1. Manual Implementation: For complex protocol upgrades, the core de-

velopment team implements the approved changes.

3.3.5 Emergency Mechanisms

To handle urgent situations:

1. Emergency Proposals: A mechanism for the core team or a super-

majority of validators to propose and quickly implement critical security

fixes.

characteristics position Electroneum to compete effectively in the global

market for blockchain solutions.

• Interoperability: The groundwork laid for cross-chain communication

opens new possibilities for Electroneum to integrate with the wider blockchain

ecosystem, potentially increasing liquidity and use cases.

19 • Sustainable Development: The introduction of on-chain governance

and a community-driven development model ensures that Electroneum can

continue to evolve and adapt to changing market needs and technological

advancements.

6.3 Addressing Challenges
