Bitcoin quantum defenses advance as Solana cuts inflation

Bitcoin’s push toward a post-quantum design took another small step this week as researchers tested an experimental protection on the mainnet. The move is meant to reduce the risk that exposed public keys could be targeted once they appear in the mempool, a part of the transaction process that remains vulnerable for a short time. The test spent a 10,000-satoshi output using a scheme designed to tie spending authority to a specific transaction.

Bitcoin tests quantum-resistant spending

The experiment was carried out by StarkWare researcher Avihu Levy, who used a quantum-safe approach called Quantum Safe Bitcoin. The method combines hash-based one-time signatures with a search process that binds authorization to a particular transfer. It is not meant as a routine payment tool; the design is closer to an emergency defense if quantum attacks become a practical concern.

Even so, the test matters because Bitcoin development has long been cautious about changes to the base protocol. The effort shows that some builders are already preparing for a future in which current cryptographic assumptions may need to be replaced or supplemented. For now, the technology remains experimental and expensive to use, with transactions taking hours to complete.

Solana validators vote to slow token growth

Solana was also in focus after validators agreed to reduce the network’s inflationary pressure. The proposal would curb what backers see as excessive token issuance and is intended to make the supply schedule less aggressive over time. That change would affect how quickly new SOL enters circulation, a key issue for holders watching dilution and network economics.

The reported figure tied to the decision was 18.9 million SOL, described as cancelled in the digest headline. The broader point is that validator governance is still shaping the economic rules of major blockchains, not just their technical road maps. In Solana’s case, the discussion centers on balancing incentives for validators with longer-term token scarcity.

The digest also pointed to a bullish Bitcoin case from Bernstein, which sees the token peaking at $500,000 in this cycle. That view sits alongside the week’s protocol developments and underscores how market narratives remain split between long-term technical risks and aggressive price expectations. For investors, the combination highlights a crypto market still driven by both engineering changes and speculative conviction.
