Key points to remember:
-
Bitcoin evolves at two paces: slow, consensual changes at the base layer and rapid experimentation at the edges.
-
Major upgrades (such as Taproot) arrive via careful soft forks after lengthy review.
-
Rapid changes like Lightning Payments and Ordinals are happening without changing the fundamental rules of Bitcoin, which is why headlines move faster than L1.
-
The “50 year” line is an indicator to examine where change is occurring, whether in the core protocol or on the periphery, before judging whether Bitcoin has actually changed.
On November 10, 2025, Ripple Chief Technology Officer David Schwartz posted a deadpan line about X: “Bitcoin is not the same today as it was 50 years ago. »
The gag works because Bitcoin (BTC) launched in 2009, so the “50 years” is obviously ironic, but it landed because it pointed to a larger truth about how people talk about Bitcoin’s evolution.
Schwartz’s joke appeared in a thread claiming that “1 BTC = 1 BTC” and that volatility exists in fiat terms, not in Bitcoin’s own unit of account. This framework often fuels absolutist views about whether Bitcoin is changing or not.
Did you know? Rajat Soni, a critic of XRP (XRP), is a CFA holder and a financial commentator focused on Bitcoin and active on X.
Joke Exposes Deadline Confusion
Schwartz’s line works because it highlights a mismatch in how people perceive time in crypto.
The headlines make it seem like Bitcoin is changing overnight, but the foundations it stands on have been built over decades:
-
Public key cryptography (Diffie-Hellman, 1976)
-
Merkle Trees (1979)
-
Proof of work precursors such as Hashcash (1997 and 2002)
-
Digital money sketches such as Wei Dai’s B-money (1998).
The design of Bitcoin in 2008 brought together decades of cryptographic work into a single operational system. Once a protocol with real value reaches large scale, change slows because coordination costs rise sharply. Researchers and manufacturers now call this dynamic “protocol ossification.”
This slowness may make it seem like nothing is changing at all, but that is not the case. A useful way to think about it is the Lindy effect, which says that the longer a non-perishable technology has survived, the longer it is likely to survive. This is why long-standing building blocks, such as public key cryptography and hash trees, continue to support newer systems. But the Lindy effect is just a heuristic, not a promise. It describes survival, not inevitability.
So when you zoom out, the joke is a reminder that Bitcoin’s evolution is happening at two different paces: the decades-long lineage of its basic ingredients and the faster cycles we see in today’s news.
Did you know? Separate Witness (Bitcoin Improvement Proposal 141) activated on August 24, 2017, fixing transaction malleability and enabling capacity and Lightning improvements.
What’s Changing at the Core of Bitcoin (And How)
At a grassroots level, Bitcoin is changing, but slowly and only with broad consensus.
Most upgrades are soft forks, which strengthen the rules enforced by nodes. Soft forks create a risk of coordination between the different versions of the software. To reduce disruption, the community has spent years refining activation methods such as the BIP-9 and BIP-8 bits.
In practice, a change moves from discussion and specification to testing and, if there is clear support, to an activation window where miners and economic nodes signal that they are ready.
Taproot is the clearest recent example. Proposed years earlier and activated in November 2021, it added Schnorr signatures and a new output type that improves efficiency and privacy without breaking existing rules.
The journey from idea to activation required extensive review and a period of minor reporting before the rules were actually enforced. This shows that improvements do indeed happen, but only after patient consensus is achieved.
Today’s debates, such as the reactivation of “OP_CAT” or the introduction of “OP_CTV” (BIP-119), follow the same pattern: proposals for incremental programmability are subject to public research, risk analysis, and social review before any activation can even be considered.
The process is as much about coordination between maintainers, reviewers, miners, and users as it is about the code.
Did you know? Bitcoin Script is intentionally not Turing complete, limiting complexity to keep validation predictable and safe for all nodes.
Where rapid changes occur
The pace picks up once we move away from the Bitcoin base layer.
Payment channels move transactions off-chain, route them through a mesh, and touch layer 1 only as a safety net. This is why the Lightning Network iterates much faster than consensus changes. Its core mechanisms, including hashed timelock contracts and newer approaches, such as point timelock contracts (PTLC), allow value to flow between intermediaries without trust.
PTLCs replace hash-based secrets with elliptic curve points, providing channels with better privacy, more flexible routing, and the ability to spread payments across multiple paths. Since these improvements reside in the implementations rather than the base protocol, they can evolve without a rigorous consensus vote.
Ordinals and inscriptions show the same rapid dynamics from another perspective: new behaviors emerge using existing rules. Casey Rodarmor’s system numbers satoshis and attaches data to them via Taproot-era scripts, creating collectibles without altering Bitcoin’s consensus. This is why the phenomenon could explode culturally, while the basic protocol remained unchanged.
Both examples highlight the joke’s divided pace: Layer 2 and client-side systems can add features, UX improvements, and even new markets at high speed, while the base layer changes rarely and deliberately. Big headlines tend to follow the edge, like Lightning upgrades or signup waves, while the core of the channel moves forward in carefully organized steps.
The deepest lesson
Schwartz’s “Bitcoin over 50 years” line holds up because it boils down how crypto actually evolves into a single joke: a slow, conservative core that rarely changes and a fast, inventive edge that changes.
The slow core is intentional. Once a monetary protocol puts billions at stake, improvements are made only after lengthy review and broad social consensus, a dynamic widely discussed as protocol ossification.
However, slowing down does not mean getting stuck. There are concrete paths of change, such as the soft-fork track for new opcodes like “OP_CAT” and “OP_CTV,” which could expand Bitcoin’s transaction programmability. These follow multi-quarter or multi-year timelines rather than news cycles.
Meanwhile, new behaviors can explode around the edges without affecting consensus. This is exactly what the ordinals and inscriptions did by numbering the satoshis and attaching data using the rules already in place.
Forget the years. Think of the note as a decoder. If a claim about Bitcoin “changing” doesn’t specify where (base layer or edge) and how (consensus upgrade or emerging use), it misses the point made by the joke.
