This document compiles all key mathematical equations and formulas used throughout the Temporal Blockchain System, providing a single, consistent reference for all mathematical aspects. Formal definitions of variables and parameters are included.

1. Temporal Distributed Trust Architecture

3. Temporal Attribution Chains

Attribution Chain Structure:

$$A(I) = {(s_1, r_1, t_1, h_1), (s_2, r_2, t_2, h_2), …, (s_n, r_n, t_n, h_n)}$$

Definitions:

  • $A(I)$: Attribution chain for information $I$.

  • $v(s_i, r_i, t_i, h_i, s_{i+1})$: Verification function for each link in the chain.

4. Proof of Temporal Authority (PoTA) Consensus

4.1 Vote Weighting

Equation:

$$W(a) = \alpha \cdot R(a, t) + (1 - \alpha) \cdot S(a, t)$$

4.2 Reputation Update Rule

Equation:

$$R(a, t+1) = R(a, t) + \beta \cdot (Accuracy(a, t) - R(a, t)) - \gamma \cdot Penalty(a, t)$$

Equation:

$$W_{faulty} < \frac{1}{3} W_{total}$$

Definitions:

  • $W_{faulty}$: Total voting power of faulty validators.
  • $W_{total}$: Total voting power of all validators.

Or, if using a reputation based model for voting/governance, a rule can exist: where the total influence from actors proven, later as bad/malicious: cannot ever exceed 1/3 of total.

4.5 System-Wide Temporal Accuracy

  • $MaximumDeviation$: System-wide parameter defining the maximum acceptable deviation.

5. Drift Compensation (Kalman Filter - Simplified)

While the full Kalman filter involves multiple equations, a simplified representation for the drift correction is:

Equation:

$$T_{corrected}(t) = T_{measured}(t) - DriftEstimate(t)$$

Definitions:

  • $T_{corrected}(t)$: Corrected time at time $t$.
  • $T_{measured}(t)$: Measured time from the atomic clock at time $t$.
  • $DriftEstimate(t)$: Estimated clock drift at time $t$, calculated by the Kalman filter.

6. Offline Timestamp Verification

Verification involves checking against pre-shared initialization vectors. No single equation fully captures this; it is a multi-step process.

Definitions:

  • $R_{time}(a)$: System’s resistance against an actor a attempting to change time values.
  • $C$: System constant.
  • $N_{diverse}$: Number of diverse TMNs in the network.
  • $S_{temporal}$: Temporal stake required to participate in consensus.

8. Long-Term Time Security

Equation: $$S_{long}(t) = S_0 \cdot e^{-\lambda t} \cdot \sqrt{N_{TMN}(t)}$$

Definitions:

  • $S_{long}(t)$: Long term security levels at a time t.
  • $S_0$: Initial security parameter.
  • $\lambda$: Decay constant related to cryptographic security.
  • $N_{TMN}(t)$: Projected number of active TMNs at time $t$.

9. Offline Security Guarantee

Equation: $$S_{offline}(t, \Delta t) = S_{base} \cdot (1 - \frac{\Delta t}{t_{max}})^2 \cdot e^{-\alpha \cdot \Delta t}$$

Definitions:

  • $S_{offline}(t, \Delta t)$: Security guarantees during an offline period, that begins at t, lasting \Delta t units of time.
  • $\Delta t$: Duration of offline operation.
  • $t_{max}$: Maximum secure offline period.
  • $\alpha$: Drift coefficient of the atomic clocks.
  • $S_{base}$: Security when the system is online.
