$XRP Ledger validator Vet has raised fresh questions about whether Bitcoin can successfully navigate the coming shift to quantum-resistant security.
He argued that the challenge may be less technical and more about community consensus.
Key Points
- $XRP validator Vet says Bitcoin faces a “social test” in adopting quantum-resistant security solutions.
- Bitcoin developers remain split on whether to use a soft fork for quantum-resistant upgrades.
- Larger quantum-safe signatures could reduce transactions per block and impact miner fees.
- Vet argues $XRP Ledger is more adaptable, with smoother upgrades and less community friction.
Bitcoin Quantum Path May Trigger Another “Civil War”
Reacting to new research from Google, Vet pointed to growing divisions within the Bitcoin community over how to respond to quantum threats. He suggested that a hard fork may ultimately be unavoidable.
Meanwhile, Vet noted that discussions highlighted in the research show Bitcoin developers and stakeholders remain split on whether a soft fork is even feasible for implementing quantum-resistant cryptography.
He explained that even if they agree on a solution, current quantum-safe signatures would make transactions larger, meaning fewer transactions could fit into each block. Increasing the block size to address this would likely reopen long-standing debates within the Bitcoin ecosystem.
The issue becomes more complex as miner rewards continue to shrink over time, making transaction fees increasingly important. If fewer transactions can be processed, miners could earn less, raising concerns about the network’s long-term sustainability.
“Social Consensus Is the Real Bottleneck”
Community voices echoed similar concerns. $XRP commentator X Finance Bull noted that while coding solutions may exist, achieving social consensus within the Bitcoin community is the hardest part.
Another user raised concerns about dormant wallets, including those linked to Satoshi Nakamoto, and questioned whether such funds could become vulnerable to a quantum attack.
Vet responded that outcomes would depend on the chosen solution, including whether inactive funds might eventually be frozen or require movement before a set deadline.
depends what solution the community opts for, but lets say there is a deadline or else the coins need to be burned/frozen, then we’ll see if he does move his coins or no.
but there’s many issues with handling inactive accounts, are they lost keys or just a long term holder?

$XRP as More Flexible in Protocol Evolution
In contrast, Vet expressed confidence in the adaptability of the $XRP ecosystem. He argued that the $XRP Ledger has a track record of implementing protocol improvements more smoothly.
He suggested that this culture of iterative upgrades could make it easier for $XRP to adopt quantum-resistant technologies without the same level of social friction.
Defining Moment for Bitcoin
Industry voices also pointed to a dilemma facing Bitcoin. Improving security with larger cryptographic signatures could slow the network and reduce fees, while increasing block size could revive past disagreements within the community.
This creates a “triple problem”: Bitcoin must balance security, speed, and miner incentives, especially as block rewards continue to decline.
The miner incentive question is the one nobody wants to answer honestly.
Quantum-resistant signatures (FALCON, Dilithium) balloon transaction size 10–50x. Fewer txns per block means fewer fees per block — exactly when subsidy is already shrinking post-halving.
So the community…

As quantum computing becomes more realistic, the issue is growing more urgent. The main question is no longer whether Bitcoin can upgrade, but whether its community can agree on the best way forward.
