Quantum computer breaks 15-bit elliptic curve cryptographic key

The Bitcoin community continues to debate whether cryptographically relevant quantum computers are imminent or decades away. Project Eleven, a quantum security research company, awarded a prize to researcher Giancarlo Lelli for using a quantum computer to break a 15-bit elliptic-curve key — a small-scale version of the same cryptography used in Bitcoin, which relies on far larger 256-bit keys. Lelli was able to derive a private key from the public key paired to it, using a “variant” of Shor’s algorithm, an integer factorization algorithm for quantum computers, according to Project…

Chainlink Is Getting Cheaper And Whales Are Not Buying The Dip: Discount Or A Trap?

XRP Sends Bullish On-Chain Signal Despite Weak Price Action

XRP is showing signs of on-chain stabilization despite trading below the average holder cost basis, according to data by Alphractal. The data points to a market still under pressure, but one where network activity, exchange supply and leverage conditions do not resemble a panic-driven breakdown. Alphractal’s asset overview places XRP’s spot price at $1.4343, below its realized price of $1.4862. That gap matters because realized price reflects the average on-chain acquisition cost across circulating XRP. With spot price below that level, the average holder is sitting on an unrealized loss.…
