Why Bitcoin’s slow core and fast-moving edges create confusion about how it actually changes
Bitcoin doesn’t update often — and that’s precisely why a one-line joke from Ripple’s chief technology officer David Schwartz caught fire this week. His post, claiming that “Bitcoin is not the same now as it was 50 years ago,” was obviously playful, yet it touched a real tension inside the industry: understanding what kind of change actually happens on the network.
Bitcoin protocol evolution
Bitcoin’s technical progress runs on two speeds. At the base layer, adjustments arrive only after broad agreement among maintainers, miners and node operators. That is why developments like Segregated Witness in 2017 or Taproot in 2021 required years of discussion before activation. These upgrades refined privacy, efficiency and signature structure without disrupting existing rules.
Experts say this deliberate tempo is part of Bitcoin’s long-term durability. “Once a monetary network reaches global scale, every modification carries enormous coordination costs,” said one blockchain researcher. He added that the system survives because its foundations move slowly, predictably and rarely.
The term protocol ossification often describes this stage — not a freeze, but a restrained path for improvement. Proposals such as OP_CAT or OP_CTV remain under review for the same reason: any expansion of programmability must be safe for all participants.
Where rapid change actually happens
Away from the core, however, innovation moves much faster. Layer-2 systems like the Lightning Network experiment with new payment designs, routing models and privacy enhancements. Features such as Point Time-Locked Contracts allow multi-path transfers and improved confidentiality without touching Bitcoin’s consensus layer.
Inscriptions and Ordinals show similar momentum. These systems emerged by creatively using existing rules introduced by Taproot, enabling digital artifacts and new market activity while leaving the protocol untouched. As one developer put it, “The edge evolves because it doesn’t require the entire ecosystem to agree first.”
The lesson behind the joke
Schwartz’s remark resonated because it highlighted how public narratives often blur these tempos. News cycles capture the fast-moving edges, while the base layer follows multi-year review, testing and activation timelines.
Understanding where change happens — the slow protocol or the fast edge — is essential to reading Bitcoin’s development. The joke simply pointed to the gap between perception and reality, and the need to separate headlines from the deeper mechanics of how the network evolves.
