Adam Back proposed a method for the secure transition of Bitcoin to new cryptographic standards., 2026/04/16 10:53:24
Adam Back, the founder of Blockstream, has stated that the safest method for Bitcoin to transition to quantum-resistant cryptography is through the gradual implementation of optional updates.
He mentioned that quantum computers are still in the early stages of development, and advancements in this field are progressing slowly. However, in the long run, such technologies could pose a threat to cryptography and wallet security.

“The safest scenario is a gradual rollout of optional updates that will enable a transition to quantum-resistant cryptography when necessary. Preparation is key to success. Making changes in a controlled manner is significantly safer than acting in a crisis,” he remarked.
Back emphasized that such modifications require time and consensus within the community, as any updates to the network affect a wide range of participants—from developers to users and node operators.
He further noted that the shift to new cryptography will likely be incremental, initially impacting new addresses and storage tools, while existing solutions can continue to operate in parallel for some time. This approach will help prevent abrupt changes in Bitcoin’s network operations and reduce the burden on users.
Previously, a group of Bitcoin developers led by Jameson Lopp introduced a new network improvement proposal (BIP-361). This proposal includes the freezing of 1.7 million BTC, which could be vulnerable to quantum attacks.
