At 15:00 UTC on Wednesday, the much-anticipated Zhejiang testnet for staking withdrawal went live on Ethereum’s Beacon chain. Zhejiang will enable the testing of the Ethereum Improvement Proposal (EIP) 4895 which allows for staking withdrawals. This is in preparation for the network’s next major update, the Shanghai hard fork slated to launch sometime in March.

What Is a BIP (Bitcoin Improvement Protocol)?
A Bitcoin Improvement Protocol (BIP) is a design document for introducing features or information to Bitcoin. BIPs are used to propose new features, improvements, or changes to the Bitcoin protocol. They are authored by members of the Bitcoin community and reviewed by developers before being implemented in a new version of the Bitcoin software.
BIPs are typically used for network protocol changes, including transaction format changes, consensus rules, or other network-level features. Once a BIP is accepted and implemented, it becomes a part of the official Bitcoin protocol and must be supported by all full nodes in the network.
BIP Process Flow
The process flow for a Bitcoin Improvement Protocol (BIP) typically involves the following steps:
- Proposal: An individual or group in the Bitcoin community proposes a new feature, improvement, or change to the Bitcoin protocol. The proposal is usually in the form of a BIP document, which includes a detailed description of the proposed change, its motivations and use cases, and any potential drawbacks or risks.
- Review: The proposal is reviewed by the Bitcoin development community, including core developers, and any feedback or suggestions are collected. This is done through mailing lists, forums, and other communication channels.
- Implementation: Based on the feedback, the proposal is implemented in a new version of the Bitcoin software. This involves writing code, testing, and ensuring that the proposed changes are compatible with the existing protocol.
- Deployment: The new version of the software is deployed to the Bitcoin network. This usually involves a hard fork, which requires all nodes in the network to upgrade to the new version to continue participating in the network.
- Maintenance: After deployment, the new feature, improvement, or change is maintained, and any issues are resolved.
The process flow can differ depending on the nature of the proposal, and some BIPs may only make it through part of the process.
Examples of Bitcoin BIPs
There have been many Bitcoin Improvement Protocols (BIPs) proposed and implemented over the years, but some of the most notable ones include:
- BIP 141 (Segregated Witness): This BIP proposed a change to the way transactions are stored in the blockchain, called Segregated Witness (SegWit). It helped address scalability issues and enabled using new features such as the Lightning Network.
- BIP 16 (Pay-to-Script-Hash): This BIP introduced a new type of transaction called Pay-to-Script-Hash (P2SH), which allows for the creation of more complex transaction scripts and multisignature addresses.
- BIP 9 (Version Bits): This BIP introduced a new mechanism for activating new features or improvements to the Bitcoin protocol in a backward-compatible way, called version bits. This made it easier to implement new features without hard-falling the network.
- BIP 148 (User Activated Soft Fork): This BIP proposed a soft fork to enforce the activation of the Segregated Witness (SegWit) protocol, a solution to address Bitcoin’s scalability issues.
- BIP 170 (Taproot): This BIP proposed a new smart contract mechanism for Bitcoin that allows for more efficient, private, and flexible smart contract capabilities
These are some examples, but many other BIPs have been proposed and implemented to improve the Bitcoin protocol.
