Freezer: shelf life of frozen bubble hash

Hi I've made bubble hash 1 year ago. And it has been in the freezer frozen fresh in a air tight container. I'm considering drying it out and perhaps making a tincture out of it. What do you guys use bubble hash for? I've made bubble hash because my crop last year had some PM, so had to make hash to ensure it is clean.

Is the bubble hash still good to use/process?

What is the shelf life of bubble hash when wet frozen?

Cheers,

Hash degrades as a function of heat, UV, oxygen, and moisture. Frozen in an airtight opaque container, it should last years.

Archeologist found some 2000-year-old hash that was still good in the very center of the brick, where it was protected.
