Blockchain protocols are the rules that govern how a blockchain network operates. They define everything from consensus mechanisms to transaction formats, ensuring all participants follow the same standards. These protocols are crucial for maintaining the integrity and security of the blockchain.
Governance in blockchain networks determines how decisions are made and implemented. From Proof-of-Work to Proof-of-Stake, different models offer unique approaches to validating transactions and adding new blocks. Challenges like and keep governance an evolving field in blockchain technology.

1 of 3
Set of rules, standards, and guidelines that govern the operation and functionality of a blockchain network
Defines consensus mechanism used to validate transactions and add new blocks to the chain (Proof-of-Work, Proof-of-Stake)
Specifies format and structure of transactions and blocks ensures compatibility across network participants
Establishes cryptographic algorithms used for securing the network maintains integrity and prevents tampering
Determines incentive structure for participants encourages participation and good behavior (, )
Ensures all participants in the network adhere to the same set of rules maintains integrity and security of the blockchain
Examples of blockchain protocols include , , and each with its own specific rules and standards
Governance models in blockchain
Proof-of-Work (PoW) governance model
Miners compete to solve complex mathematical problems to validate transactions and add new blocks
Miner who solves the problem first is rewarded with cryptocurrency (Bitcoin) and transaction fees
Requires significant computational power and energy consumption leads to concerns about centralization and environmental impact
Proof-of-Stake (PoS) governance model
Validators are chosen to create new blocks based on the amount of cryptocurrency they hold and "stake" as collateral
More stake a validator has, higher their chances of being selected to create a new block and earn rewards
More energy-efficient than PoW may lead to greater decentralization, as it does not require expensive mining equipment
Delegated Proof-of-Stake (DPoS) governance model token holders vote for delegates to validate transactions
Proof-of-Authority (PoA) governance model set of approved validators take turns creating new blocks
Blockchain Governance
Protocol changes through consensus
Formal proposal process, such as (BIPs) or (EIPs)
Developers or community members submit detailed proposal outlining suggested changes, rationale, and implementation plan
Proposal is reviewed, discussed, and debated by the community through forums, mailing lists, and other communication channels
Achieving consensus on proposed changes requires majority of network participants to agree on implementation
Specific consensus threshold may vary depending on blockchain protocol and significance of proposed changes
Consensus reached through various methods, such as on-chain voting, off-chain signaling, or combination of both
Approved changes implemented through network upgrade or
Hard fork is a backward-incompatible change to the protocol requires all participants to upgrade their software to the new version
Participants who do not upgrade will be left on a separate, incompatible chain
Challenges of blockchain governance
Decentralization
Ensuring decision-making power is distributed among diverse set of stakeholders, rather than concentrated in the hands of a few
Balancing need for community input with efficiency of decision-making processes
Scalability
Implementing changes that enable blockchain network to handle growing number of transactions and users without compromising performance or security
Balancing need for scalability with desire to maintain decentralization and accessibility for all participants
Enabling blockchain protocol to adapt and evolve over time to address new challenges, incorporate new features, and fix vulnerabilities
Managing complexity of coordinating network upgrades across decentralized network of participants with varying interests and incentives
Governance models must strike balance between these competing priorities while ensuring long-term sustainability and resilience of the blockchain network
