Proposer-Builder Separation (PBS)

Proposer-Builder Separation (PBS) Key Points

• Proposer-Builder Separation (PBS) is a protocol design concept in blockchain technology.
• PBS splits the roles of proposing and building blocks in the blockchain network.
• This separation aims to enhance blockchain performance, security, and decentralization.
• PBS can reduce the risk of censorship and collusion in blockchain networks.
• It features prominently in the design of Ethereum 2.0.

Proposer-Builder Separation (PBS) Definition

Proposer-Builder Separation (PBS) is a concept in blockchain architecture that involves separating the roles of proposing new blocks and building the content of these blocks. This separation is aimed at improving the overall performance, security, and decentralization of blockchain networks.

What is Proposer-Builder Separation (PBS)?

Proposer-Builder Separation (PBS) is a design principle in blockchain technology.
It involves dividing the roles of proposing new blocks and building the content of these blocks into separate entities.
This division is aimed at enhancing blockchain performance and security and promoting decentralization.

Who Uses Proposer-Builder Separation (PBS)?

Proposer-Builder Separation is used primarily in blockchain networks and by blockchain developers.
It is a fundamental part of the Ethereum 2.0 design, which aims to improve the scalability, usability, and sustainability of the Ethereum blockchain.
PBS is particularly relevant to Proof of Stake (PoS) systems, but it can be applied to other consensus mechanisms as well.

When is Proposer-Builder Separation (PBS) Used?

Proposer-Builder Separation is used during the block creation process in a blockchain network.
When a new block needs to be added to the chain, the roles of proposing the block and building its content are performed separately according to PBS principles.

Where is Proposer-Builder Separation (PBS) Applied?

Proposer-Builder Separation is applied in the blockchain network infrastructure.
It is a part of the protocol design and impacts how transactions are processed and blocks are added to the blockchain.

Why is Proposer-Builder Separation (PBS) Important?

Proposer-Builder Separation is important because it enhances the performance, security, and decentralization of blockchain networks.
By splitting the tasks of proposing and building blocks, it reduces the risk of censorship and collusion within the network.
This separation also allows more participants in the network, promoting decentralization and making the network more robust and secure.

How Does Proposer-Builder Separation (PBS) Work?

In Proposer-Builder Separation, the role of proposing new blocks is separate from the role of building the content of these blocks.
Builders gather transactions and create block content, which is then proposed by proposers to be added to the blockchain.
This separation reduces the power and influence of any single participant, making the network more decentralized and secure.
