In Layer 1

Stellar has set out its Bell upgrade, with a vote scheduled for November 23 and a post-quantum security focus. The upgrade has also been framed as part of a wider push toward quantum-safe blockchain design.

What this rests on

Claim by claim, with its source
✓
Stellar announced the Bell upgrade ahead of a November 23 vote, with post-quantum security as a core feature.
✓
Stellar is moving forward with Bell while XLM price scenarios are being discussed around the upgrade.
✓
The Bell upgrade is being positioned as Stellar’s post-quantum security effort, alongside similar work from Tron and Starknet.

What it means

Stellar’s Bell upgrade sits in the part of network maintenance where protocol changes are voted on before they are activated, and the November 23 vote gives the process a clear checkpoint. Post-quantum security has become a visible theme for blockchain networks as they prepare for threats that sit beyond today’s standard cryptography. Bell places Stellar in that category, with the upgrade framed around stronger protection for the network’s future.

For builders and holders on Stellar, a post-quantum upgrade means the network is signaling a technical shift that may eventually change how security is handled at the protocol level. That can affect wallet support, infrastructure planning, and how applications think about long-term key management on XLM-related systems. The practical issue is less about immediate user action than about whether the chain is aligning itself with a newer security standard before other ecosystems do.

Bell also reflects a broader race among blockchain projects to be seen as ready for post-quantum cryptography, with Tron and Starknet named in the same category. The trade-off is familiar in crypto: strengthening protocol security can improve resilience, but it also pushes networks into more complex engineering choices that users rarely see until upgrades arrive. Stellar’s move shows how security competition is becoming part of network positioning, not just a back-end technical matter.
