For the First Time in Three Years, the Sixth Bitcoin Core Maintainer Emerges

Odaily星球日报Published on 2026-01-14Last updated on 2026-01-14

Abstract

On January 8, Bitcoin Core appointed developer TheCharlatan as its sixth core maintainer, the first such addition since 2023. Core maintainers hold trusted keys and are responsible for merging code into Bitcoin Core repository and signing official releases, ensuring the software’s authenticity and security. There are now six trusted maintainers, including Marco Falke, Gloria Zhao, Ryan Ofsky, Hennadii Stepanov, and Ava Chow. The role of a core maintainer is compared to an "editor" in the development process—they review and approve code contributions but do not have unilateral power to change on-chain rules. Bitcoin upgrades still depend on broader community consensus. TheCharlatan, a computer science graduate from the University of Zurich, has been contributing to Bitcoin Core since 2018 and has over a decade of experience in crypto development. He is known for his work on improving Bitcoin Core’s verification logic and modularization. His appointment was supported by at least 20 Bitcoin Core developers. The article also highlights the historical context of Bitcoin Core maintainers, noting that Satoshi Nakamoto originally held sole maintainer authority, which was later decentralized. Core maintainers are highly trusted individuals within the community, with significant influence over the project’s development direction.

On January 8, the Bitcoin Core team promoted developer TheCharlatan (X: @sedited) to core maintainer, making him the sixth member to hold trusted keys. The other five core maintainers with trusted keys include: Marco Falke (promoted in 2016), Gloria Zhao (promoted in 2022), Ryan Ofsky (promoted in 2023), Hennadii Stepanov (promoted in 2021), and Ava Chow (promoted in 2021).

This appointment marks the first addition of a trusted key holder since 2023. Over the past decade, only 13 people have been granted this permission, highlighting its importance and the strictness of the selection process.

Bitcoin Core Maintainers: The 'Editors' of Bitcoin Developers

Bitcoin Core is currently the primary development and maintenance team for the Bitcoin mainnet. It is responsible for writing, maintaining, testing, and releasing the majority of the full node software, along with accompanying tools and documentation. Bitcoin Core is non-profit and operates mainly on funding from external companies.

The Bitcoin Core development team consists of 41 members who contribute the vast majority of the project's code. Among them, only 6 developers are granted the status of 'Core Maintainer'—they are the only six people in the world with the authority to merge code into Bitcoin Core and sign the released program files (binaries).

Signatures of the 6 core maintainers

To draw an analogy, Bitcoin Core maintainers are like the 'editors' of the Bitcoin network developers; anyone can contribute code and submit PRs to the codebase, but only the core maintainers have the authority to merge code into the official codebase and sign releases. This is similar to editors reviewing manuscripts, deciding whether developers' code is accepted for publication or returned for modification.

The signatures of Bitcoin Core maintainers ensure security, giving all nodes and users confidence that the release is 'official and unaltered.' However, Bitcoin Core maintainers do not have the direct power to trigger changes to on-chain rules. For example, even if Bitcoin Core maintainers have signed and released program files for a soft fork or hard fork of the Bitcoin network, the actual success of the upgrade depends on adoption and consensus from users and miners, not just the signatures of the Bitcoin Core maintainers.

When Bitcoin was first created, Satoshi Nakamoto was the only core maintainer, with sole authority to change the core codebase. Later, Satoshi passed this privilege to Gavin Andresen, who then passed it to Wladimir van der Laan. This means that for a long time, the power to maintain/change the Bitcoin network code was in the hands of one person. It wasn't until 2022, when Wladimir van der Laan stepped down and became embroiled in litigation with Craig Wright (who claims to be Satoshi Nakamoto), that this power began to be decentralized.

Even so, Bitcoin Core maintainers still play a crucial role. Those who become core maintainers typically have high levels of trust and reputation within the community or have made outstanding contributions to the Bitcoin network.

For example, one core maintainer, Ava Chow, is a transgender female developer. In 2024, when Bitcoin core developer Luke Dashjr wanted to restrict Ordinals transactions at the consensus level, it was she who rejected Luke Dashjr's PR on the grounds of 'no consensus and creating noise,' preventing a potential severe split in the Bitcoin network consensus and becoming an unsung hero.

For introductions and contributions of other core maintainers, please refer to previous articles(related reading:Who is guarding Satoshi's legacy? A look at the 41-person army behind Bitcoin's trillion-dollar market cap). Next, we will introduce why TheCharlatan became the sixth core maintainer.

TheCharlatan: A Decade of Experience in Crypto Development

TheCharlatan graduated from the University of Zurich with a degree in computer science. He is South African and focuses on reproducibility and the verification logic of Bitcoin Core. In a 2024 blog post, he claimed to have been developing this project for over two years. TheCharlatan's work involves systematically splitting, organizing, and modularizing Bitcoin Core's verification logic, allowing other users to safely reuse it.

TheCharlatan

TheCharlatan is widely popular among Bitcoin Core developers. In the process of promoting him to core maintainer, at least 20 members expressed their approval. When nominating him, glozow praised: 'He is a reliable reviewer with extensive experience in key areas of the codebase, thoughtful about what we deliver to users and developers, and very familiar with the technical consensus process.'

Bitcoin Core core developer group chat content (translated)

According to his GitHub account information, TheCharlatan first started crypto development in 2015 by creating a cryptocurrency price display tool. This tool was a simple Linux desktop widget with built-in price alerts that triggered when set thresholds were reached. His crypto development activities became more frequent after 2017. He began contributing code to Bitcoin Core in 2018, so it can be inferred that TheCharlatan first encountered Bitcoin Core 8 years ago, making him a veteran.

It is also worth noting that in 2021-2022, TheCharlatan contributed to a Farcaster project codebase. This project allowed people to exchange Bitcoin and Monero peer-to-peer with anyone running a Farcaster node.

TheCharlatan does have a 'soft spot' for Monero. In 2020, he researched the potential destruction issues caused by using hardware wallets to transfer Monero and discussed time-lock vulnerabilities in Monero.

Of course, true tech geeks can be somewhat elusive. TheCharlatan often retweets technical posts on platform X but rarely expresses his own opinions (in May 2025, he posted that he hates NFTs even more). However, since June 2025, he has been repeating a tweet every month that says: 'Cash on the internet. No auto-updates.'

I was afraid this might be some kind of secret code among Bitcoin tech geeks or a cultural slogan I wasn't aware of, so I asked AI to explain the meaning of these two sentences. The AI said these two sentences actually express an extreme Bitcoin fundamentalist view:

'True internet-native cash should be as simple, brutal, and immutable as cash. Once you start with automatic updates, governance votes, and frequent rule changes, it's no longer cash; it becomes another centralized/semi-centralized/manipulable 'digital bank account'.'

The 'Summer Saw' Continues: A Break Above $67,000 Could Signal the Start of Bitcoin's Rally

Bitcoin continues to consolidate within a $58,000–$67,000 range, with its price dropping to $62,217 on August 1st. Analysts are divided on the next direction. Trader Crypto Candy suggests a potential drop towards $60,000 if the price remains below $66,000. Investor Jelle refers to the prolonged sideways movement as a "summer saw" and maintains a dollar-cost averaging strategy. The key upside scenario hinges on a breakout above $67,000. Daan Crypto Trades states that without this, the movement risks being just an extended pause. Roman projects a sharper rise to $70,000–$80,000+ if a breakout occurs with sufficient volume. Macro-analyst Gert van Lagen views this as an accumulation phase within a multi-year "cup and handle" pattern. He notes that long-term holders are refusing to sell, as indicated by the NUPL metric staying far from capitulation. In summary, the market is in an accumulation phase, with the $60,000 and $67,000 levels being critical. A break above $67,000 could initiate significant growth, while a fall below $60,000 may lead to further decline. The recent pullback shows that legislative catalysts have provided only short-lived momentum, raising questions about the sustainability of any future breakout attempts.

Stocks Are Plummeting More Sharply Than Cryptocurrencies. Where Has the Money Gone?

Stock Markets Plunge Deeper Than Cryptocurrencies: Where Did the Money Go? In late July, Seoul's Kospi index triggered circuit breakers for two consecutive days, plummeting over 40% from its June high. The collapse was led by heavyweight stocks like SK Hynix, whose record profits still disappointed investors, and devastating leveraged ETFs, with one major product losing over 83% of its value. This signaled a global, forced deleveraging targeting the most crowded trades. Interestingly, while stocks exhibited extreme volatility akin to crypto markets, Bitcoin rose nearly 15% in July after a prior steep drop. Analysis shows the money fleeing equities did not flow into Bitcoin. Instead, Bitcoin had already absorbed its sell-off in May-June, when U.S. spot Bitcoin ETFs saw historic outflows. The true safe-haven beneficiary was gold, whose price rose over 20% year-on-year, highlighting a decoupling between Bitcoin and gold as "digital gold." The sell-off was a targeted unwinding of leveraged positions in tech and semiconductors, accelerated by broker-dealer risk management and shifts in the AI narrative, including new competition from Chinese memory chipmakers. The retreat path was clear: from high-valuation tech stocks to cash and U.S. Treasuries, then to gold. For Bitcoin to attract sustained institutional inflows, conditions like eased global liquidity pressure, a "soft-landing" Fed rate cut, and U.S. regulatory clarity via legislation like the stalled CLARITY Act are needed. Currently, Bitcoin is not a safe haven but an already-cleared asset. Its low correlation with tech stocks, however, makes it a potential diversification play for institutional portfolios once the storm passes. The money isn't here yet, but the positioning is underway.

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

The available information indicates that DIGITAL GOLD ($BITCOIN) does not have any known institutional backers or prominent venture capital investments. The project seems to operate on a peer-to-peer model focused on community support and adoption rather than traditional funding routes. Its activity and liquidity are primarily situated on decentralized exchanges (DEXs), such as PumpSwap, rather than established centralized trading platforms, further highlighting its grassroots approach. How DIGITAL GOLD ($BITCOIN) Works The operational mechanics of DIGITAL GOLD ($BITCOIN) can be elaborated on based on its blockchain design and network attributes: Consensus Mechanism: By leveraging Solana’s unique proof-of-history (PoH) combined with a proof-of-stake (PoS) model, the project ensures efficient transaction validation contributing to the network's high performance. Tokenomics: While specific deflationary mechanisms have not been extensively detailed, the vast maximum token supply implies that it may cater to microtransactions or niche use cases that are still to be defined. Interoperability: There exists the potential for integration with Solana’s broader ecosystem, including various decentralized finance (DeFi) platforms. However, the details regarding specific integrations remain unspecified. Timeline of Key Events Here is a timeline that highlights significant milestones concerning DIGITAL GOLD ($BITCOIN): 2023: The initial deployment of the token occurs on the Solana blockchain, marked by its contract address. 2024: DIGITAL GOLD gains visibility as it becomes available for trading on decentralized exchanges like PumpSwap, allowing users to trade it against SOL. 2025: The project witnesses sporadic trading activity and potential interest in community-led engagements, although no noteworthy partnerships or technical advancements have been documented as of yet. Critical Analysis Strengths Scalability: The underlying Solana infrastructure supports high transaction volumes, which could enhance the utility of $BITCOIN in various transaction scenarios. Accessibility: The potential low trading price per token could attract retail investors, facilitating wider participation due to fractional ownership opportunities. Risks Lack of Transparency: The absence of publicly known backers, developers, or an audit process may yield skepticism regarding the project's sustainability and trustworthiness. Market Volatility: The trading activity is heavily reliant on speculative behavior, which can result in significant price volatility and uncertainty for investors. Conclusion DIGITAL GOLD ($BITCOIN) emerges as an intriguing yet ambiguous project within the rapidly evolving Solana ecosystem. While it attempts to leverage the “digital gold” narrative, its departure from Bitcoin's established role as a store of value underscores the need for a clearer differentiation of its intended utility and governance structure. Future acceptance and adoption will likely depend on addressing the current opacity and defining its operational and economic strategies more explicitly. Note: This report encompasses synthesised information available as of October 2023, and developments may have transpired beyond the research period.
