Según Decrypt, una investigación publicada por Glassnode muestra que casi un tercio del Bitcoin en circulación tiene claves públicas expuestas, lo que teóricamente lo hace vulnerable a futuros ataques de computadoras cuánticas. Específicamente, alrededor de 6,04 millones de Bitcoins, con un valor de más de 46.900 millones de dólares, están en riesgo cuántico. Entre ellos, aproximadamente 1,92 millones están expuestos estructuralmente, originados en direcciones tempranas de "pago a clave pública" (pay-to-public-key), estructuras multifirma y salidas Taproot, que son formatos de script que exponen claves públicas por defecto.
Alrededor de 4,12 millones están expuestos operacionalmente, debido a comportamientos de reutilización de direcciones. Entre los Bitcoins con exposición operativa, aproximadamente 1,66 millones están relacionados con exchanges, lo que representa el 8,3% del suministro total y cerca del 40% de todos los Bitcoins con exposición operativa. De las tenencias de los principales exchanges, solo el 5% de los Bitcoins de Coinbase están expuestos al riesgo cuántico, mientras que Binance y Bitfinex tienen tasas de exposición del 85% y 100%, respectivamente. Glassnode afirma que este resultado no debe interpretarse como una clasificación de riesgo de empresas específicas ni como una señal de solvencia.
