In the ever-evolving landscape of digital currency, Bitcoin stands as the pioneering force that introduced the world to the concept of cryptocurrency. At its core, Bitcoin transactions represent the transfer of value between participants within the Bitcoin network. These transactions are securely recorded on the blockchain, ensuring transparency, immutability, and decentralization. However, as the network and its user base have grown, so too have the demands for more sophisticated transaction types, particularly in terms of security and flexibility. This is where Partially Signed Bitcoin Transactions (PSBTs) come into play, marking a significant advancement in the way Bitcoin transactions are conducted.
PSBTs are a relatively new addition to the Bitcoin protocol, designed to enhance transaction security while maintaining the network’s foundational principles. The concept of a Partially Signed Bitcoin Transaction emerged from the need to facilitate more complex transactions, such as those requiring signatures from multiple parties before execution. PSBTs address this need by allowing a transaction to be partially signed by one or more parties and then completed by others at a later stage. This process not only improves security by enabling offline (or cold storage) signing but also increases the versatility of Bitcoin transactions, accommodating a wider range of use cases.
The significance of PSBTs in the Bitcoin network cannot be overstated. They represent a leap forward in making Bitcoin transactions more secure, flexible, and user-friendly. By simplifying the process of multi-signature transactions and enhancing compatibility between different Bitcoin wallets and services, PSBTs are paving the way for a more inclusive and robust Bitcoin ecosystem. As we delve deeper into the intricacies of Partially Signed Bitcoin Transactions, it becomes clear that they are a critical development in the ongoing evolution of Bitcoin, offering enhanced transaction security and opening new possibilities for users and developers alike.
At its simplest, a Bitcoin transaction involves the transfer of Bitcoin value from one address to another on the Bitcoin network. This process is underpinned by blockchain technology, a decentralized ledger that records all transactions across a network of computers. Each transaction is comprised of inputs and outputs: inputs refer to the source of the Bitcoin being sent, while outputs designate the recipient(s). For a transaction to be valid, the total amount of inputs must equal the total amount of outputs, ensuring the conservation of value within the system.
Digital signatures play a crucial role in the security and integrity of Bitcoin transactions. When a user initiates a transaction, they must sign it with their private key, a secure digital code known only to the owner. This signature proves the user’s ownership of the Bitcoin being sent and authorizes the transfer. It’s akin to signing a check in the traditional banking system but with a critical difference: digital signatures are cryptographically secure, making them nearly impossible to forge. The public key, associated with the user’s Bitcoin address, is used to verify the signature without revealing the private key, ensuring the transaction is both secure and authentic.
While the Bitcoin network offers a revolutionary approach to digital currency, traditional Bitcoin transactions are not without their challenges. One significant issue is the lack of flexibility in transaction types, particularly for complex scenarios requiring multiple signatures or specific conditions to be met. For instance, multi-signature transactions, which provide an added layer of security by requiring approval from multiple parties, can be cumbersome and difficult to implement with standard Bitcoin transactions.
Moreover, the process of signing transactions with private keys poses a security risk if not handled correctly. Storing private keys on internet-connected devices exposes users to potential theft through hacking. Conversely, keeping keys entirely offline in cold storage makes it difficult to sign transactions in a timely and efficient manner.
These challenges highlight the need for a more versatile and secure method of conducting Bitcoin transactions, leading to the development of Partially Signed Bitcoin Transactions (PSBTs). PSBTs address these issues by allowing transactions to be partially signed and completed later, facilitating complex transaction types and enhancing overall transaction security.
The concept of Partially Signed Bitcoin Transactions (PSBT) emerged from the growing need within the Bitcoin community for a standardized way to handle complex transactions, particularly those requiring inputs from multiple parties before finalization. As Bitcoin’s adoption widened, so did the variety of its use cases, pushing the boundaries of what traditional Bitcoin transactions could accommodate. This evolution highlighted the limitations of existing transaction formats, especially in scenarios involving multi-signature setups, cold storage, and cross-wallet compatibility.
Recognizing these challenges, developers sought to create a solution that would retain the security and decentralization of Bitcoin while introducing the flexibility needed for advanced transaction types. The result was the proposal and subsequent development of PSBT, a format designed to enhance the Bitcoin transaction process by allowing transactions to be built incrementally, signed by different parties at different stages, and finally broadcasted to the network once fully signed.
The formal introduction of PSBTs to the Bitcoin ecosystem came through Bitcoin Improvement Proposal 174 (BIP 174), authored by Andrew Chow in 2017. BIP 174 outlines the specifications for the PSBT format, detailing how transactions can be constructed, signed, and transmitted between parties and wallets before being finalized. The proposal aimed to address several key issues, including the difficulty of conducting multi-signature transactions, the risks associated with exposing private keys during the signing process, and the lack of interoperability between different Bitcoin wallets and software.
BIP 174 defines a standardized structure for PSBTs, ensuring compatibility and ease of use across the Bitcoin network. It specifies how additional information necessary for signing a transaction, such as UTXO (Unspent Transaction Output) details and scripts, can be included within a PSBT. This allows signers to verify transactions without access to the entire blockchain, facilitating secure offline signing and enhancing the overall security of the Bitcoin network.
The introduction of PSBT marked a significant evolution in the way Bitcoin transactions are conducted. Traditional transactions, while secure and effective for straightforward transfers, lacked the flexibility required for more complex interactions on the blockchain. With the advent of PSBT, users gained the ability to engage in sophisticated transaction types without compromising on security or decentralization.
PSBTs have made multi-signature transactions more accessible and secure, enabling a broader range of use cases, from enhanced security protocols for individual users to complex contractual agreements between multiple parties. They have also significantly improved the usability of cold storage solutions, allowing users to sign transactions in a secure offline environment and then broadcast them to the network, reducing the risk of private key exposure.
The development and adoption of PSBTs represent a pivotal moment in the ongoing maturation of the Bitcoin network. By addressing the limitations of traditional transactions, PSBTs have opened new avenues for innovation and use, further solidifying Bitcoin’s position as the leading cryptocurrency.
Partially Signed Bitcoin Transactions (PSBT) introduce a flexible and secure method for conducting Bitcoin transactions, especially in scenarios requiring inputs from multiple parties. The PSBT process begins with the creation of a transaction template that includes all the necessary information except for the signatures. This template can be passed between parties, allowing each to sign the transaction with their private keys without exposing those keys to others. Once all necessary signatures are collected, the transaction can be finalized and broadcast to the Bitcoin network.
Multi-signature setups, which require two or more signatures to authorize a transaction, greatly benefit from the PSBT format. PSBT simplifies the process of gathering signatures from multiple parties, each of whom may be using different wallets or signing devices. By allowing each participant to sign the transaction independently and securely, PSBTs enhance the security and flexibility of multi-signature transactions, making them more accessible and easier to manage.
A PSBT includes several technical components crucial for its functionality:
The PSBT process significantly enhances the security, flexibility, and interoperability of Bitcoin transactions, particularly for complex scenarios like multi-signature setups.

One of the most significant benefits of PSBTs is the enhanced level of security and privacy they provide. By allowing transactions to be signed offline, PSBTs minimize the risk of private key exposure to potentially malicious online environments. This offline signing process, often referred to as “cold storage” signing, ensures that private keys never have to leave the secure environment of a hardware wallet or other cold storage device. Furthermore, PSBTs support advanced transaction types like CoinJoin, which mixes multiple transactions together, thereby obfuscating the trail of individual bitcoins and enhancing user privacy.
PSBTs have been designed with interoperability in mind, facilitating seamless interactions between various wallets and Bitcoin software. Prior to PSBT, executing transactions across different wallets, especially those involving complex scripts or multi-signature requirements, could be cumbersome and error-prone. PSBTs standardize the transaction format, making it easier for different systems to understand and process transactions. This interoperability extends the functionality of Bitcoin wallets and software, enabling users to leverage a wider range of tools and services without compatibility issues.
The flexibility of the PSBT format makes it an ideal solution for executing complex transaction types that go beyond simple transfers of bitcoin between two parties. Multi-signature transactions, which require approval from multiple key holders before execution, are greatly simplified by PSBTs. This simplification is crucial for organizations and high-security applications where multiple parties must consent to transactions. Additionally, PSBTs facilitate the execution of privacy-enhancing transactions like CoinJoin, as well as other innovative transaction types that contribute to the robustness and versatility of the Bitcoin network.
The ability to sign transactions offline is perhaps one of the most critical features of PSBTs, addressing a fundamental concern regarding the security of private keys. Offline signing allows users to sign transactions in a completely air-gapped environment, far removed from the reach of online attackers. Once signed, the PSBT can be securely transferred to an online device for broadcasting to the Bitcoin network. This process not only enhances security but also provides peace of mind to users, knowing their private keys remain safe from online vulnerabilities.
In summary, the adoption of Partially Signed Bitcoin Transactions offers a multitude of benefits, including enhanced security and privacy, improved interoperability between wallets and software, support for complex transaction types, and the facilitation of offline signing.

Here, we explore the real-world applications and use cases of PSBT, illustrating its versatility and impact on the cryptocurrency landscape.
One of the most prominent applications of PSBT is in the realm of multi-signature (multi-sig) wallets. These wallets require signatures from multiple private keys before a transaction can be executed, providing an additional layer of security compared to traditional single-signature wallets. PSBT simplifies the process of creating and signing transactions in multi-sig setups by allowing each participant to sign the transaction independently, without the need to share sensitive information or expose private keys. This feature is particularly valuable for organizations, investment groups, and families who wish to jointly manage funds with enhanced security protocols.
PSBT also plays a crucial role in facilitating CoinJoin transactions, a method for enhancing privacy by combining multiple transactions into a single transaction with several inputs and outputs. By obscuring the links between inputs and outputs, CoinJoin makes it more challenging to trace the flow of bitcoins, thereby increasing anonymity for users. PSBTs enable participants in a CoinJoin transaction to independently sign their portion of the transaction in a secure manner, contributing to the pooled transaction without compromising their privacy.
The ability to sign transactions offline is a critical advantage of PSBT, especially for users who prioritize security. Cold storage solutions, such as hardware wallets and paper wallets, keep private keys completely offline, safeguarding them from online threats. PSBT facilitates the process of signing transactions in these secure environments, allowing users to generate signatures without connecting their storage device to the internet. Once signed, the PSBT can be safely transferred to an online device for broadcasting to the Bitcoin network, minimizing the risk of key exposure.
PSBTs are instrumental in executing atomic swaps, a type of cross-chain transaction that enables the exchange of cryptocurrencies across different blockchain networks without the need for a trusted third party. Atomic swaps rely on smart contracts to ensure that the exchange is executed fairly, requiring participants to sign off on the transaction for it to proceed. PSBTs streamline the signing process for atomic swaps, allowing participants to securely sign transactions on their respective blockchains. This capability not only enhances the security and efficiency of atomic swaps but also contributes to the broader interoperability between distinct blockchain ecosystems.
In practice, PSBTs have opened up a world of possibilities for Bitcoin users, developers, and organizations. By addressing key challenges related to security, privacy, and interoperability, PSBTs have facilitated a more versatile and user-friendly Bitcoin network. Whether through enhancing the security of multi-signature wallets, increasing privacy with CoinJoin transactions, enabling secure offline signing, or simplifying atomic swaps, PSBTs have proven to be a valuable addition to the cryptocurrency landscape.
