Сообщение ChainCatcher, Blockstream выпустила предложение по улучшению биткойна (BIP), предложив схему постквантовой подписи SHRINCS. SHRINCS — это основанная на хэшах схема постквантовой подписи, минимальный размер которой составляет 548 байт, что примерно в 9 раз больше существующих подписей Schnorr, но значительно меньше одобренных NIST схем ML-DSA и SPHINCS+. Эта схема прошла тестирование в производственной среде на побочной цепи Liquid и включает в себя копию белой книги биткойна.У этой схемы также есть ограничения. BIP предупреждает, что доказательства безопасности еще не завершены, и схема является состоянием, при каждой подписи необходимо хранить использованный ключ, подпись будет увеличиваться на 16 байт с каждым использованием, а в случае потери устройства потребуется около 5777 байт для восстановления безсостояния откатной транзакции. Blockstream оценивает, что после внедрения SHRINCS биткойн сможет поддерживать скорость около 3 TPS, если объединить с агрегированием ZK-доказательств, скорость может увеличиться до 6.7 TPS.
