Stellar will mark its preliminary step into the post-quantum (PQ) period of security by way of the Bell upgrade scheduled for November.
According to Stellar, the upgrade goals to allow sensible contracts to have native PQ signatures, calling it one of many “two long-term goals.”
It’s (Bell upgrade) designed to make sensible accounts prepared for companies at scale and begin the work on two longer-time period targets: quantum-secure signatures and quicker ledgers.
The upgrade, also referred to as Protocol 30, will hit Testnet on the third of November. If all goes properly, the vote and ultimate upgrade might be pushed to mainnet by the twenty third of November.
While this gained’t make the entire Stellar stack quantum-safe, it is a commendable a part of broader preparations forward of the 2029 deadline.
Stellar’s quantum roadmap
Powerful quantum computer systems can break elliptic curve cryptography, which is at present getting used to safe most blockchains and Internet techniques.
Google, which is actively engaged on a quantum laptop, has set 2029 as the inner deadline to make its techniques quantum-safe. In reality, it urged the blockchain business to additionally use the identical deadline. As a part of its response to the risk, Stellar [XLM], like most blockchains, unveiled a plan to be quantum-safe.
For Stellar, the goal is 2027, however enterprise wallets had been anticipated to have quantum-safe signing by the top of 2026. That’s the step the Bell upgrade will obtain on the sensible contract stage.
The second section might be to increase the same safe signing to plain wallets and accounts in 2027. Finally, the community consensus layer (validator node signatures) will even have safe post-quantum signatures. That places it near Tron and Starknet, that are additionally pushing to overtake their stack to be quantum-safe.
Impact on Stellar’s XLM
Stellar has bagged a number of partnerships, together with plugging in and distributing tokenized belongings (RWA) by the Depository Trust & Clearing Corporation (DTCC).
In reality, DeFiLlama knowledge reveals that Stellar has 6x extra RWA belongings (about $3 billion) than stablecoin exercise ($487 million).


That mentioned, XLM bounced about 5% following the replace and was up 7% this week. Bulls appear to have defended the September low and brief-time period demand assist of $0.17.
However, the market construction was nonetheless bearish. Only a decisive transfer above $0.19 (transferring averages) might affirm a possible extension of the restoration.


Final Summary
- Stellar to kick off its post-quantum plan with the Bell upgrade in November.
- The post-quantum push will initially goal sensible contracts and enterprise wallets.
