Staking on the OKTC blockchain offers users a powerful way to earn passive income by participating in network security and governance. By staking OKT tokens and delegating to validators, users contribute to consensus while receiving regular rewards. This guide dives deep into the mechanics behind OKTC staking rewards, covering everything from block reward distribution and voting weight calculation to withdrawal methods and lock-up periods.
Whether you're a beginner exploring decentralized staking or an experienced validator operator, understanding the algorithmic foundation of OKTC’s proof-of-stake system is essential for maximizing returns and ensuring long-term participation.
How OKTC Staking Works
OKTC operates on a delegated proof-of-stake (DPoS) consensus model powered by the Tendermint engine. Users can stake a minimum of 10,000 OKT to become a validator node or delegate smaller amounts—starting at just 0.0001 OKT—to existing validators.
Every 252 blocks (known as an epoch cycle), the network evaluates all validator nodes based on their total voting weight. The top 21 validators with the highest weight become active block producers for the next epoch, responsible for validating transactions and creating new blocks. The remaining nodes serve as standby (alternative) validators.

Validators earn block rewards and transaction fees, which are then distributed between themselves and their delegators based on a commission rate set by the validator. This rate ranges from 0% to 100%, allowing validators to attract more delegations by offering competitive returns.
For example, if a validator sets a commission rate of 0.6 (60%), they keep 60% of the earned rewards, while the remaining 40% is shared among delegators proportionally to their stake.
Core Components of the Staking System
Key Roles in the Network
Understanding the roles within the OKTC ecosystem clarifies how rewards flow through the network:
- Candidate: Any user who registers as a validator but isn’t among the top 21.
- Validator: One of the top 21 nodes that produce blocks and participate in consensus.
- User: Any individual holding OKT tokens.
- Delegator: A user who stakes OKT by voting for one or more validators to earn rewards.
- Proposer: The validator selected in each round to propose the next block, chosen based on stake size and availability.
Sources of Staking Rewards
Staking rewards on OKTC come from two primary sources:
- Block Rewards: Newly minted OKT tokens awarded for block production.
- Transaction Fees: Fees paid by users for executing transactions on the network.
The total supply of OKT is capped at 21 million, following a deflationary issuance model similar to Bitcoin. Block rewards are halved approximately every nine months, reducing inflation over time.
| Deflation Date | Block Reward (OKT) |
|---|---|
| March 18, 2023 | 0.125 |
| December 17, 2023 | 0.0625 |
| September 16, 2024 | 0.03125 |
| June 17, 2025 | 0.015625 |
| March 18, 2026 | 0.0078125 |
This predictable reduction ensures long-term token scarcity and sustainable staking incentives.
Voting Weight and Reward Distribution
How Voting Weight Is Calculated
Each OKT token carries a fixed voting weight of 11,700,000. This multiplier was standardized after protocol upgrade v1.7.2, replacing earlier dynamic decay mechanisms.
| OKT Amount | Voting Weight |
|---|---|
| 1 | 11,700,000 |
| 10 | 117,000,000 |
| 100 | 1,170,000,000 |
A validator’s total weight determines its chance of being selected as a block producer. Higher weight increases both influence and potential earnings.
Multi-Voting and Delegation Flexibility
OKTC supports multi-voting, allowing users to delegate to up to 30 different validators. This diversification reduces risk and increases resilience against individual validator downtime.
Once a user stakes and votes, subsequent stakes automatically apply to previously selected validators unless changed manually.

Reward Calculation Mechanics
To ensure fairness and accuracy, OKTC uses a period-based reward tracking system.
Key Concepts in Reward Tracking
- Period: A continuous sequence of blocks during which a validator’s total voting shares remain unchanged.
- Reward Ratio: Total rewards divided by total shares in a given period.
- Cumulative Reward Ratio: The sum of all reward ratios across past periods.
- User Earnings: Calculated as
Cumulative Reward Ratio × User Shares.
When a delegator changes their stake (e.g., adds or removes OKT), it triggers a new period. This allows precise tracking of earnings over time without continuous recalculations.
Example Scenario
Suppose Delegator A holds 50 shares across three periods:
| Period | Validator Rewards | Total Shares | Reward Ratio | Cumulative Ratio |
|---|---|---|---|---|
| m-3 | 10 OKT | 100 | 0.1 OKT | 0.1 |
| m-2 | 10 OKT | 500 | 0.02 OKT | 0.12 |
| m-1 | 10 OKT | 450 | 0.0222 OKT | 0.2422 |
If Delegator A withdraws after m-2, their earnings are:
(0.12 − 0) × 50 = 6 OKT
This system ensures transparent, tamper-proof reward distribution.
Withdrawing Staking Rewards
Users can claim rewards in two ways:
- Active Withdrawal: Manually initiate a transaction to withdraw rewards from a specific validator.
- Passive Withdrawal: Automatically triggered when a user re-delegates, stakes again, or modifies their vote.
⚠️ Note: Due to precision truncation, only up to four decimal places are credited to users (e.g., 1.5521 OKT). Any amount beyond—the fifth decimal and smaller—is sent to the community fund pool.
Example:
- User receives:
1.5521 + 0.3921 + 24.3034 = 26.2476 OKT - Community pool receives:
0.00007 OKT(residual fractions)
This setting can be modified through on-chain governance proposals.
Unstaking Process and Lock-Up Period
To unstake OKT, users must submit an on-chain request. Once initiated:
- A 14-day locking period begins.
- During this time, unstaked tokens earn no rewards.
- Multiple unstake requests within the same period are merged, resetting the countdown from the latest request timestamp.
- Minimum unstake amount: 0.0001 OKT
Plan withdrawals carefully to avoid extended idle periods.
Frequently Asked Questions (FAQ)
What is the minimum amount needed to stake on OKTC?
You can delegate with as little as 0.0001 OKT. However, becoming a validator requires at least 10,000 OKT.
How often are staking rewards distributed?
Rewards accrue continuously with each block but can be withdrawn at any time via active or passive methods.
Can I change my validator after staking?
Yes. You can redelegate your stake to another validator at any time, which triggers a passive reward withdrawal from the original node.
Why did I not receive the full decimal amount of my reward?
Due to precision limits, only up to four decimal places are paid out; the remainder goes to the community fund pool.
When will block rewards be halved again?
The next halving is scheduled for June 17, 2025, reducing the block reward to 0.015625 OKT per block.
Does voting for multiple validators increase my APR?
Not directly—APR depends on validator performance and commission rates—but spreading stakes reduces risk and may stabilize overall returns.
