Lost coins do not disappear from the state.
They stop taking part in economic life, but the system can still carry them as if they might wake up tomorrow.
Plain-language overview
Why add expiry and renewal to a Bitcoin-like system?
Because lost or forgotten value does not vanish just because nobody can use it. OBTC explores whether very long dormancy should eventually trigger a system response instead of being treated as untouchable forever.

Start from the gap
Bitcoin solved ownership. It did not really answer permanent abandonment.
The cost is not obviously zero.
Nodes still maintain the relevant state, and the network still absorbs the long-horizon burden.
The security question keeps moving closer.
As subsidy falls, a proof-of-work chain eventually needs a clearer story about how security stays paid for.
What OBTC changes
OBTC adds one controversial rule: very long dormancy is not ignored forever.
Assign a long lifecycle
Every coin gets a long stewardship window rather than being assumed safe in perpetuity without attention.
Let active holders reset it
Normal movement or renewal creates a fresh window. The rule is aimed at neglect, not ordinary use.
Make dormancy reclaimable
If nobody acts for long enough, the system can route the value through a reclaim path instead of leaving it untouched forever.
Split value instead of deleting it
Most value follows a refund path; the rest is redirected to support network security.
What this means in practice
For active users, the model is mostly about visibility and occasional renewal.
It favors stewardship over silence.
The idea is that serious long-term holders should be able to verify and renew value periodically instead of disappearing for years with no system response.
It makes timing legible.
Wallets and interfaces are expected to show lifecycle risk clearly instead of hiding it as background uncertainty.
Open questions
The proposal is arguable by design.
Is this confiscation?
The OBTC argument is that long-term state has a cost, so the rule makes that cost explicit. Whether that feels fair is part of the experiment.
Does it punish patient holders?
Not if the renewal window is genuinely long and the tooling is good. The intended target is abandonment, not patience.
Why not leave dormant value alone?
Because leaving it alone is also a policy choice. OBTC simply tries a different one and makes it testable.
Why read further even if you disagree?
Because the project turns an abstract debate into something concrete enough to inspect, accept, reject, or refine.
In one sentence
OBTC asks whether digital scarcity should remain permanently silent, or whether a long-lived system should eventually bring abandoned value back into a governed cycle.
