Cryptographer Nik Bougalis has returned to XRP Ledger development, submitting a proposed overhaul of a foundational data type used in the network's server software. The move hands maintainers a concrete code to evaluate more than three years after his departure from Ripple in 2022.

Bougalis filed pull request #8300 to the XRPLF/rippled repository under the title “I'm back, baby.” The proposal centers on base_uint, a widely used integer type in the codebase, and seeks to strengthen how the software handles its underlying data structures. Because the repository is maintained publicly under the XRP Ledger Foundation (XRPLF), the review of the proposal will play out in the open, where any developer can follow it.

Ripple CTO Emeritus David Schwartz acknowledged Bougalis's return on X, highlighting their long history of working together. The pull request itself, however, does not indicate that Schwartz has resumed active XRP Ledger development.

Proposal Targets Core Data Types

The proposed changes would use 64-bit elements within base_uint where the underlying system architecture supports them. Bougalis also proposes eliminating unsafe raw pointers and constructors that can accept certain values without adequate checks. Wrapper integer types of this kind sit underneath much of the arithmetic in a C++ codebase, and raw-pointer misuse is a well-known source of memory-safety defects, which is why compile-time checks are a common focus of hardening work.

The revisions are intended to make certain programming errors easier to detect at compilation time rather than after the software is running — a distinction that matters for infrastructure, where errors surfaced during a build can be fixed before any server is deployed. The revised implementation could also improve some operations on compatible systems, although the proposal does not establish that it would deliver a network-wide performance increase.

Additional safeguards around a heavily used data type could also make it harder for developers to use the structure incorrectly. That potential benefit remains dependent on testing and on compatibility with the rest of the XRP Ledger codebase.

Maintainer Review Still Required

Because pull request #8300 remains a proposal, the changes have not automatically become part of XRP Ledger server software. Maintainers must review the implementation, evaluate testing results and determine whether the code should be merged — the standard path for changes to a publicly hosted codebase, where review comments and test outcomes are visible to anyone following the repository.

That review is particularly important for foundational components, since a change to a commonly used type can affect multiple parts of the software beyond the files directly modified in the proposal.

The proposed revisions do not introduce a new transaction type or activate a new ledger amendment. Their eventual impact therefore depends on the development and review process rather than an immediate change to the network. For developers, the central question is whether the revised implementation can provide stronger safeguards while maintaining the behavior required by existing XRP Ledger components.

Bougalis spent nearly a decade contributing to XRP Ledger and related protocol development during his time at Ripple. After leaving the company in 2022, he later served as chief technology officer of the Algorand Foundation in 2025.

RippleX engineering head H. Ayo Akinyele has also connected Bougalis's return with broader technical challenges facing the project. The latest pull request provides a specific area of development work rather than a change to the ledger's user-facing functionality.

Schwartz has previously said that the prospect of working with Bougalis again could be a reason for him to return to coding himself. His reaction to the latest submission alone, however, does not establish that he has returned to active development.

For now, Bougalis's contribution represents a return to XRP Ledger source-code development through a proposed change to one of its underlying data structures. The outcome of pull request #8300 will depend on maintainer review, testing and a decision on whether the revisions should be incorporated into the server software — and its progress, from reviewer feedback to a possible merge, would be traceable in the repository itself.
