You propose a staking mechanism that impose increasing returns based on the lock-up period of funds: the longer you lock your tokens, the higher your reward rate. Conversely, a short-term commitment results in a lower yield.
This approach creates a financial trade-off between liquidity and returns, encouraging investors to adopt a long-term outlook while discouraging pure speculation.

Critique of the Tiered Mechanism

1. Short-term Supply Shock

• If several participants initially committed for a 10% return and this is later reduced to 5% for certain durations, they may withdraw their funds en masse.
• This abrupt exit would increase the supply of circulating tokens, putting downward pressure on the price.

2. Speculation and Stakers on Polkadot

• Contrary to the assumption that such a system would limit speculation, there are virtually no pure speculators on DOT: Yield investors, who are by definition long-term investors.
• Pure speculators do not engage in staking, as it involves locking up their funds.

3. Advantage of Rapid Unstaking

• The ability to quickly unstake is reassuring for those concerned about crypto market volatility.
• This option attracts new participants:
  • Investors already holding DOT can stake for short periods.
  • These short sessions reduce the circulating supply and energize the ecosystem.

4. Balance Between Stakers and Speculators

• Staking and speculation are two distinct but complementary dynamics.
• Currently, Polkadot only offers incentives for stakers, with no dedicated mechanisms for speculators.
• This asymmetry creates an imbalance, a loss of confidence, and reduced demand (and price) for DOT.

In summary: For your system to be viable, the current logic of “rapid end-of-year destaking” must be completely rethought. Users should be given a choice between several options. In that case, the system becomes both brilliant and viable, as it incentivizes staking for both long-term and speculative visions.

Proposed Mechanism: Lock-up Tier System

1. Standard Lock-up Durations Offered
Users choose fixed lock-up periods:

Tier	Duration
Bronze	2 days
Silver	28 days
Gold	6 months
Platinum	12 months
Diamond	2 years

---

2. Associated Reward Scale

Tier	Duration	Annual Rate (APY)
Bronze	2 days	4%
Silver	28 days	Current APY
Gold	6 months	Higher than current APY
Platinum	12 months	Higher than current APY
Diamond	2 years	Higher than current APY

I’m not smart enough to model APY bonuses and time ratios. All I can say is that the current 28-day period, if kept, should match the current APY to avoid causing a supply shock. If we want to reduce it, we can do so by offering a lower yield — but still higher than the dollar — to encourage staking and help fight real-world inflation.The problem is that the “Higher APy” is funded by those who choose to go bronze. But right now, for me, those people don’t exist — so I don’t know how we’re supposed to fund it in the short term.A dynamic vision makes more sense than a fixed one, but I believe we recently removed that dynamism in favor of a fixed approach — or maybe I’m wrong?
