Bitcoin Improvement Proposals: How They Are Making Bitcoin Better
Bitcoin Improvement Proposals (BIPs) are a critical part of how Bitcoin grows and evolves. BIPs are proposed solutions that keep the Bitcoin network current and up-to-date with the most advanced technology. With these solutions, Bitcoin is continuing to become more appropriate for use in our modern world.
In simpler terms, BIPs are protocols, guidelines, and processes created to improve the current features of Bitcoin, as well as to propose new features and improvements. BIPs are suggestions submitted by members of the Bitcoin community and, if accepted, validated, and tested, the suggestions will be integrated into the current Bitcoin protocol.
BIPs are essential for keeping the Bitcoin network secure and up-to-date. They also help to ensure Bitcoin remains trustworthy and allow for advances to be made as quickly as possible. BIPs are also important because they allow anyone to participate in the process of making Bitcoin better. Everyone can submit a BIP, and anyone can have their voices heard in a safe and open-minded environment.
Understanding BIPs will give you valuable insights into the current state of Bitcoin and its future development.
In this blog, we will explore the history of BIPs, the different types of BIPs, and the impact that BIPs have had on Bitcoin. We will also discuss the future of BIPs and how they are shaping the future of the cryptocurrency landscape.
The History of Bitcoin Improvement Proposals
BIPs first emerged in 2011, created by Amir Taaki. Initially intended as a way for developers to communicate with the broader community, these proposals grew in complexity. This led to BIPs being used as a form of documenting and tracking proposed changes to Bitcoin.
Today, BIPs are important documentations that anyone looking to become involved with Bitcoin should be aware of. BIPs consist of a comprehensive list of proposed changes and feature descriptions that anyone can review if they want to participate in Bitcoin's decision-making process.
BIPs have made an incredible impact on Bitcoin's evolution and growth. They have helped to make Bitcoin more secure, more efficient, and more user-friendly. BIPs have also helped to ensure that Bitcoin remains a decentralized and open-source project.
BIPs have also been essential for fostering unity and a shared vision between the Bitcoin community and developers, without which Bitcoin would not have experienced the incredible growth it has seen over the last few years.

Types of Bitcoin Improvement Proposals
There are different types of BIPs, each with its purpose. The following are the most common types of BIPs:
Soft forks are like software updates that tighten the rules of the network. They introduce new features or modifications without causing any disruption. The interesting aspect of a soft fork is that it's backward compatible, meaning older nodes don't need to upgrade to maintain consensus with the rest of the network. An example of a soft fork is BIP 141, which introduced SegWit to improve transaction scalability.
Hard forks are changes to the Bitcoin protocol that are not backward-compatible. This means that nodes that do not implement the hard fork will not be able to communicate with nodes that do. Hard forks are often used to make major changes to Bitcoin, and if some nodes choose not to upgrade, they'll end up on a separate chain, creating a new network. An example of a hard fork is Bitcoin Cash, which split from Bitcoin in 2017.
User-activated Soft Forks
User-activated soft forks (UASF) are a unique type of soft fork where users, rather than miners, drive the adoption of a new feature. These proposals empower users to signal support for a change, essentially "voting" for its implementation. A notable example of a UASF is BIP 148, which helped push through the adoption of SegWit.
Consensus changes are changes to the Bitcoin protocol that affect the way that blocks are created or verified. Consensus changes are some of the most important types of BIPs, as they can have a major impact on the security and stability of the Bitcoin network. An example of a consensus change is BIP 9, which introduced a new method for signaling support for soft forks.
Improvement Proposals for Scaling, Privacy, and Security
These BIPs focus on enhancing specific aspects of Bitcoin's functionality, such as making transactions faster, improving privacy, or bolstering security. Examples include BIP 324, which proposed a new encryption scheme for peer-to-peer communication, and BIP 340, which introduced the Schnorr signature algorithm to improve privacy and scalability.
The BIP Process
There is a standard process for BIPs as it helps to ensure that all proposals are considered carefully and that only the best ideas are implemented. The BIP process also helps to ensure that all changes are made in a way that is compatible with the existing Bitcoin infrastructure. The BIP process consists of the following steps:
- BIP submission: Anyone can submit a proposal by following the guidelines set out in BIP 0001. The proposal must be submitted to the Bitcoin development mailing list.
- BIP discussion and feedback: Once a proposal has been submitted, it is open for discussion and feedback from the community. The BIP author must respond and provide feedback whenever required.
- BIP implementation and adoption: If the proposal receives broad support, the next step is to implement the proposed changes in the Bitcoin software. This involves writing and testing the code to ensure that it works as intended and is compatible with existing systems. Once the implementation is complete, it's time for the broader community - miners, node operators, and wallet providers - to adopt the new features by upgrading their software.
- BIP activation and deployment: If a proposal involves a change to the Bitcoin network, it must be activated before it can be deployed. BIP activation is a process that involves a majority of nodes signaling their support for the change. Once a BIP has been activated, it is deployed to all nodes on the network.
Notable Bitcoin Improvement Proposals
There have been many notable BIPs that have had a significant impact on the development of Bitcoin. Some of the most notable ones include:
- BIP 9: Version bits with timeout and delay - BIP 9 introduced a new way to activate changes to Bitcoin. It uses version bits, which are flags that can be set in blocks, to signal support for a change. If a majority of blocks show support for a change, the change is activated.
- BIP 32: Hierarchical Deterministic (HD) Wallets - HD wallets use a tree-like structure to generate child wallets from a master seed. This makes it possible to create an unlimited number of wallets from a single master seed, and it also makes it possible to recover lost wallets. HD wallets are now the standard way to generate Bitcoin wallets.
- BIP 141: Segregated Witness (SegWit) - SegWit is a major improvement to the Bitcoin protocol that reduces the size of transactions and makes them more efficient. SegWit does this by separating the signature data from the transaction data. This allows for more efficient validation of transactions and it also frees up space in blocks for more transactions. SegWit has had a significant impact on the scalability of Bitcoin.
- BIP 148: Mandatory activation of Segregated Witness (SegWit) - BIP 148 played a pivotal role in the adoption of SegWit. As a UASF, BIP 148 empowered users to signal their support for SegWit, ultimately leading to its activation on the network
- BIP 340-342: Schnorr/Taproot upgrade - BIP 340-342 introduced a new signature scheme called Schnorr, which is more efficient and secure than the previous signature scheme. These BIPs also introduced a new feature called Taproot, which allows for more complex smart contracts to be created without compromising the privacy of the users.
- BIP 174: Partially Signed Bitcoin Transactions (PSBTs) - PSBTs allow multiple parties to collaborate on the creation of a transaction, without revealing their private keys to each other. PSBTs are a valuable tool for developers and businesses that want to create complex transactions, such as Lightning Network payments.
Controversies Surrounding Bitcoin Improvement Proposals
While BIPs have undoubtedly played a critical role in advancing the Bitcoin network, they haven't been without their fair share of controversies. As with any collaborative effort, differing opinions and interests can lead to debates and disagreements. Some of the most common controversies include:
One of the most contentious aspects of BIPs is the potential for hard forks, which result in the creation of a new network. Hard forks can divide the community, as was the case with the Bitcoin Cash split in 2017. While some argue that forks are necessary for innovation and growth, others believe they erode the value and stability of Bitcoin.
Some critics argue that certain proposals may inadvertently lead to increased centralization, concentrating power among a few key players and undermining the decentralized nature of the network.
It can be difficult to build consensus around BIPs. This is because there are a variety of different stakeholders in the Bitcoin ecosystem, and they all have different needs and priorities. For example, miners, developers, and users all have different perspectives on BIPs, and it can often be difficult to find a solution that everyone agrees on.
The Future of Bitcoin Improvement Proposals
BIPs are essential for maintaining Bitcoin's relevance and ensuring that it remains an eminent technology. As new challenges and opportunities emerge, the community will continue to rely on BIPs to drive innovation and address critical issues.
There are always new BIPs under development or discussion, reflecting the dynamic nature of the Bitcoin ecosystem. Some of these proposals may focus on enhancing privacy features, improving scalability, or addressing security concerns. As these proposals progress through the rigorous review process, they have the potential to shape the future of Bitcoin and its underlying technology.
The implementation of BIPs can have far-reaching effects on the Bitcoin network. By introducing new features or refining existing ones, BIPs can improve the overall user experience and expand Bitcoin's capabilities. As a result, BIPs can enhance the sustainability and adoption of Bitcoin by making it more accessible, secure, and efficient for users worldwide.
Furthermore, BIPs not only impact the future of Bitcoin but also contribute to the broader evolution of the cryptocurrency landscape. Other projects are drawing inspiration from Bitcoin and its improvement process thus, the concept of BIPs is being adopted by various cryptocurrencies, fostering innovation across the entire industry.
BIPs have been essential for the development and growth of Bitcoin, providing the structure for the proposal and discussion of changes. The BIP process is critical for making consensus-based decisions and fostering a shared vision between developers and the Bitcoin community, allowing Bitcoin to remain decentralized and open-source.
BIPs have had a major impact on Bitcoin's evolution, and they will continue to be important in the years ahead as they help to drive innovation and expand Bitcoin's capabilities.
BIPs are also contributing to the broader evolution of cryptocurrencies, serving as a model for other projects and opening the door for further innovations across the industry.
Ultimately, BIPs have been an essential element in Bitcoin's success, and their importance for Bitcoin's future development cannot be overstated.
