This market resolves YES if the Bitcoin Blake2b (BTCB2/XBT) network adopts and activates a consensus rule requiring newly mined coinbase rewards to remain unspendable for more than 180 days (25,920 blocks) within six months of October 28, 2026.

The extension must be enforced by the network's active consensus rules, rather than merely proposed, merged into a software repository, or included in an optional software release.

This market resolves NO if no qualifying extension is activated before April 28, 2027, at 11:59 PM Central Daylight Time (CDT).

Clarifications:

• A maturity period of exactly 180 days (25,920 blocks) does not qualify.

• Extensions beyond 25,920 blocks qualify, including proposals establishing approximately 280-day or one-year maturity periods.

• Temporary extensions qualify if successfully activated.

• Software releases, pull requests, and miner signaling alone do not qualify without evidence of network enforcement.

• Extensions applying exclusively to historical coinbase rewards do not qualify.

Resolution sources: Bitcoin Blake2b blockchain data, Bitcoin Knots development repositories, and independent blockchain monitoring services.

Context: Multiple proposals to extend Bitcoin Blake2b coinbase maturity are under consideration, including 180-day and one-year arrangements.
