Terms and Features


Contracts in ReUnion is a software program that records interpersonal agreements and manages ReUnion currencies that are generated from the exchange between the two people. A contract is created by at least one user and made of agreement content and a checkpoint. All contracts are encrypted and are not on blockchain.

First Contract Stage (CS-1)

First Contract Stage/ First-Stage Contract (CS-1): All contracts that are unilaterally created starting at the CS-1. It is private to the user and does not demand the responsibility of other users. CS-1 is for personal reflection. A CS-1 contract can also be a bilateral one when the user invites their partner to pair with the contract, and their partner accepts it.

Personal Token

A Personal Token (PT) is a token that is uniquely generated for a user when the user creates an Activity contract. A PT is non-fungible, and can only be owned by the user who generates them. A PT can have two statuses: non-monetary (symbolic) and monetary. The PT can only be owned by the assigned user. All Personal Tokens, regardless of status, are not tradable and cannot circulate.

Non-monetary Personal Token (symbolic PT)

All Personal Tokens begin as a symbolic token that has no monetizable value. A non-monetary PT is stored in a CS-1 Relationship (CS-1) contract, including a Self-Relationship contract.

Monetary Personal Token (monetized/validated PT)

A monetary PT can exist in all contract stages. PTs attain a monetary value when their owner deposits fiat money. A monetized PT can be combined with another monetized PT from a different owner and become a Composite Coin. The PTs that are returned after Composite Coins dissolve maintain value, but as PTs, they are not tradable in the system. Users may trade them again by composing a new Composite Coin with other PT owners.

Second Contract Stage (CS-2)

Second Contract Stage/ Second-Stage Contract (CS-2): when two users accept a contract, it becomes a Second-Stage Contract. Users must use monetized PTs to validate the CS-2 contract. The deposited money is the starting fund for the relationship and may be used to purchase goods and services. The CS-2 gives space for an autonomous investment of the relationships by the contract partners. This may also be used as an automated management tool for group insurance or a communal fund, through a collection of P2P contracts.

Composite Coin

A Composite Coin (CC) is a social currency that is uniquely composed of the Personal Tokens of two users. CC is the only tradable currency circulating in the system, and can only create through a CS-2 or CS-3 Relationship Contract. CCs are used to validate the contracts between the two PT owners, and can only be spent with the mutual consent of the two users. A CC as a combined currency represents a unit of value, which can be used to record the deposit from the PT owner or to receive an equivalent sum of subsidy. When a contract ends, the associated CC will be liquidated based on prior agreements (if applicable), history of activity and ReUnion liquidity policy, and return as PTs accordingly to PT owners[11].

Third Contract Stage (CS-3)

Third Contract Stage/ Third-Stage Contract (CS-3): A CS-3 is eligible for government subsidies. The contract is eligible for subsidies based on a history of a CS-2 and an agreement for its continuation for a set period, as designated by the related funding body’s policy. In this stage, all transactions must be validated through Proof-of-Relations. Each PT owner will have a limited amount of slots to create CS-3.


Proof-of-Relations is a social-driven authentication method[12] that is mandatory for creating a CS-3 contract. It asks six users who share a CS-2 or CS-3 contract with either or both PT owners of the intended contract[13]. We do not include an additional reward incentive for people to make a proof-of-relations and we aim for this to be anonymous.

Self-Relationship Contract

Self-Relationship Contract is a mandatory contract for each ReUnion user, which does not require another user to participate. Self-Relationship can exist in CS-1 and can only store PTs (symbolic and monetary) so far.

Relationship Contract

Relationship is one of two contract types in the ReUnion system. It is made by a single user (unilateral CS-1) or two users (bilateral CS-1, CS-2, and CS-3). A Relationship contract manages the belonging Activity contracts and the circulation of CCs that are associated with it.

Activity Contract

An Activity is the second contract type in the ReUnion system. It records a transaction within a Relationship contract that allows the PT owner(s) to create and manage tasks. Activities are usually short term and finished when both the PT owner(s) agree that they are satisfactorily completed[14]. The exchanges of Activities will generate PTs and contribute to the value of CCs based on the agreement in the Relationship contract.

Personal Token owner (PT owner)

Personal Token owner is the person who holds Personal Tokens that are uniquely linked to their account. PT owner can only hold their own PT and use their own PT to combine CCs and create contracts with others. PT owner in this paper also refers to “one party of the mentioned/targeted contract”.


A Checkpoint is the end date of the contract's validity[15]. All contracts, regardless of which type and stage they are in, are required to set a Checkpoint. All Relationship contracts in CS-2 and CS-3 must begin with a one-year validity[16]. Activity contracts are not bound by the one-year validity rule.

After both parties accept the Checkpoint, users are not able to change the terms of the contract until the Checkpoint is reached unless an emergency suspension is triggered. When a contract approaches the Checkpoint, ReUnion Network will suggest to the users to discuss their relationship status and decide to extend, revise, or terminate the contract.

Emergency Suspension

Emergency Suspension is an emergency mechanism when violence or excessive breaches of an agreement is reported by either one or both of the PT owners, or a user who is outside of the targeted contract but has a CS-2 or CS-3 contract with one of the PT owners in the case of the PT owner is physically or mentally disabled.

Undivided Attention (Time)

Undivided Attention is a type of time recognized in the ReUnion system in which people expect a continuous block of concentrated time for one issue.

Routine (Time)

Routine is a type of time recognized in the ReUnion system, and people expect a (relatively) small amount of time for similar issues that repeatedly take place in a (relatively) short period, such as daily routine, once a week or month.

In The Mind (Time)

In The Mind is a type of time recognized in the ReUnion system in which people spend time thinking, exploring, feeling, emotionally processing, an issue, or a relationship. The measure of this category of time is not subjected to the universal metric of day, hour, and minute.
