Justly is designed as a cryptoeconomic dispute resolution protocol, where security emerges from incentive alignment, economic cost, and transparent execution — not from authority or legal enforcement. This section describes the security assumptions, guarantees, and limits of the protocol.

​
Security Philosophy

Justly does not attempt to determine absolute truth or legal correctness. Instead, it is designed to ensure that:
  • dishonest behavior is economically costly,
  • coordinated manipulation is difficult and expensive,
  • and honest participation is the most rational strategy over time.
Security in Justly is achieved through game theory, staking mechanics, and protocol-enforced execution, not through trust in any centralized actor.

​
Threats Justly Is Designed to Mitigate

Justly is explicitly designed to mitigate the following classes of attacks:

​
Sybil Attacks

Mitigated through:
  • economic staking requirements,
  • proof-of-humanity and identity primitives (where enabled),
  • and cost proportional to participation.
Creating many identities does not grant proportional influence, only proportional risk.

​
Vote Manipulation and Collusion

Mitigated through:
  • random juror selection,
  • commit–reveal voting,
  • incoherent vote slashing,
  • and tier-based security escalation.
Collusion requires sustained coordination across multiple rounds and jurors, increasing economic exposure.

​
Bribery and Coercion

Mitigated through:
  • juror anonymity,
  • delayed vote revelation,
  • and lack of pre-commitment visibility.
Bribery becomes unreliable because outcomes cannot be verified before execution.

​
Low-Quality or Random Voting

Mitigated through:
  • loss of stake for incoherent votes,
  • rewards only for alignment with final outcomes,
  • and long-term negative expectancy for careless behavior.
Jurors who do not evaluate evidence are economically penalized over time.

​
Incentive Alignment as the Primary Defense

Justly’s primary security mechanism is incentive alignment, not identity or reputation alone. Key properties:
  • Jurors are economically exposed to the quality of their decisions.
  • Economic exposure scales risk and reward.
  • Rewards are only distributed to jurors who align with the final outcome.
This structure discourages whales, favors independent judgment, and aligns rational behavior with protocol integrity.

​
Tier-Based Security Escalation

Justly supports multiple security levels to match guarantees with dispute risk. Higher security levels provide:
  • broader juror participation,
  • higher total economic exposure,
  • and increased resistance to manipulation.
This allows users and integrators to choose a security level proportional to the value and complexity of the dispute.

​
Appeals as a Security Amplifier

Appeals are a core security layer in the Justly design, increasing the cost of incorrect or adversarial outcomes. In the live contracts today, disputes finalize in a single round once executed. Appeals are one of the most urgent roadmap priorities and are designed to be introduced as structured escalation rounds. Planned appeal rounds:
  • increases juror count and economic exposure,
  • re-evaluates the dispute under stricter conditions,
  • and incentivizes early honest voting.
Appeals are designed to converge outcomes toward coherent judgments without granting unilateral power to any party.

​
Limits of the System

Justly makes the following guarantees:
  • outcomes are enforced exactly as defined,
  • rules are transparent and immutable,
  • execution is on-chain and verifiable.
Justly does not guarantee:
  • legal correctness,
  • absolute truth,
  • or immunity from all forms of coordination under extreme conditions.
Human judgment is inherently probabilistic. Justly guarantees that dishonesty is costly, not impossible.

​
Progressive Security

Security in Justly increases through:
  • higher security levels,
  • appeals,
  • identity primitives,
  • and protocol adoption scale.
The protocol is designed to remain secure under realistic conditions and to strengthen as participation grows.
