 The Replicator rewards are to be delivered to replicators from the mining pool after successful PoRep validation. The per-PoRep reward amount is determined as a function of the total network storage redundancy at the time of the PoRep validation and the network goal redundancy. This function is likely to take the form of a discount from a base reward to be delivered when the network has achieved and maintained its goal redundancy. An example of such a reward function is shown in **Figure 3**

 A high-level schematic of Solana’s crypto-economic design is shown below in **Figure 1**. The specifics of validation-client economics is described in [Section 2](ed_validation_client_economics.md) including validation protocol-based rewards ([Section 2.1](ed_vce_state_validation_protocol_based_rewards.md)), validation transaction fee dynamics ([Section 2.2](ed_vce_state_validation_transaction_fees.md)) and validator-client compensation for replication verification ([Section 2.3](ed_vce_replication_validation_transaction_fees.md)). [Section 2.4](ed_vce_validation_stake_delegation.md) closes with a discussion of stake delegation. [Section 3](ed_replication_client_economics.md) will review the Solana network design for global ledger storage/redundancy and replicator-client economics ([Section 3.1](ed_rce_storage_replication_rewards.md)) along with a replicator-to-validator delegation mechanism designed to aide participant on-boarding into the Solana economy ([Section 3.2](ed_rce_replication_client_reward_auto_delegation.md)). [Section 4](ed_economic_sustainability.md) dives deeper into Solana’s design for long-term economic sustainability and outlines the constraints and conditions for a self-sustaining economy. Finally, in [Section 5](ed_attack_vectors.md), various attack vectors will be described and potential vulnerabilities explored and parameterized.

 Over time, the interest rate, at any network staked percentage, will drop as described by an algorithmic schedule. Validation-client interest rates are designed to be higher in the early days of the network to incentivize participation and jumpstart the network economy. This mining-pool provided interest rate will reduce over time until a network-chosen baseline value is reached. This is a fixed, long-term, interest rate to be provided to validator-clients. This value does not represent the total interest available to validator-clients as transaction fees for both state-validation and ledger storage replication (PoReps) are not accounted for here. A validation-client interest rate schedule as a function of % network staked and time is shown in** Figure 2**.
