What is Inactive Stake on Solana Blockchain?

Key Points

• Inactive stake on the Solana blockchain likely refers to staked SOL that is not currently earning rewards or participating in the network’s consensus process.
• Research suggests this can happen during activation or deactivation periods, due to improper stake management, or because of minimum balance requirements for rent.
• The evidence leans toward inactive stake not earning rewards, but proper management can help maximize earnings and network contribution.

What is Inactive Stake on Solana Blockchain?

Definition
Inactive stake on the Solana blockchain is staked SOL (Solana’s native cryptocurrency) that is not currently active in the network’s consensus mechanism. This means it is not earning rewards or helping secure the blockchain by validating transactions.

Why It Happens

• Activation Period: When you first delegate SOL to a validator, it starts as inactive and takes time (typically one epoch, about 2-3 days) to become active and start earning rewards.
• Deactivation Period: When you undelegate (unstake) SOL, it enters a cooldown period (also about one epoch) where it is in the process of becoming inactive, though it may still earn rewards during this time.
• Improper Management: If you add more SOL to an existing stake account without properly activating it, the additional SOL remains inactive and doesn’t earn rewards. Instead, you should create a new stake account and delegate it.
• Minimum Balance for Rent: Each stake account requires a small amount of SOL to cover rent (a fee to keep the account active), and this minimum balance is always inactive and cannot be used for staking.

Impact
Inactive stake does not earn rewards, which means it doesn’t contribute to your passive income from staking. It also reduces the network’s overall security if a large portion of stake is inactive. Proper management, such as creating new stake accounts for additional SOL, can help keep your stake active and earning.

How to Manage
If you have inactive stake, you can fix it by deactivating it, waiting for the cooldown period, and then redelegating it to a validator. Tools like the Solana Compass Staking Dashboard can also help manage and reactivate inactive stake efficiently.

Detailed Survey Note on Inactive Stake on the Solana Blockchain

This section provides a comprehensive exploration of inactive stake on the Solana blockchain, expanding on the direct answer with detailed insights for users seeking a deeper understanding. The analysis is grounded in authoritative sources, including official Solana documentation, community resources, and technical guides, ensuring a thorough and professional overview.

Introduction to Staking on Solana

Solana is a high-performance blockchain known for its fast transaction speeds and scalability, utilizing a combination of Proof-of-Stake (PoS) and Proof-of-History (PoH) consensus mechanisms. Staking SOL (Solana’s native token) involves delegating it to validators, who process transactions and secure the network, in exchange for potential rewards based on inflation rates, total staked SOL, and validator performance. However, not all staked SOL is always active and earning rewards, leading to the concept of “inactive stake.”

Defining Inactive Stake

Inactive stake refers to staked SOL that is not currently participating in the network’s consensus process and, consequently, is not earning staking rewards. This state can arise due to several factors, each of which impacts the staker’s earnings and the network’s overall efficiency. The balance of a stake account on Solana can be split into four states: inactive, activating, active, and deactivating, with inactive stake being a critical component to understand for effective staking.

Reasons for Inactive Stake

Research suggests several scenarios where stake becomes inactive, each with specific implications:

1. During the Activation Period:

• When SOL is first delegated to a validator, it starts in an “inactive” state and transitions to “activating.” This warmup period typically lasts one epoch (approximately 2-3 days), during which the stake is considered inactive for determining the stake held by a validator and incurs no rewards.
• Only after this period does the stake become “active” and start earning rewards. This process is designed to ensure network stability and prevent rapid stake changes.

1. During the Deactivation Period:

• When a staker decides to undelegate their SOL (unstake), the tokens enter a “deactivating” or “cooling down” state, lasting about one epoch. During this period, the stake is considered active for reward purposes but is in the process of becoming inactive. Once fully deactivated, it becomes withdrawable but earns no further rewards.
• This cooldown is crucial for maintaining network stability by preventing rapid stake distribution changes.

1. Improper Stake Management:

• A common issue, as highlighted by resources like Solanacompass, occurs when stakers transfer additional SOL to an existing stake account via a standard transfer. Solana’s system requires a period of “activating” the stake before it can earn rewards, and transferred SOL does not automatically activate.
• This results in inactive stake that earns no rewards, while the initial stake in the account continues to earn. To avoid this, stakers should create a new stake account, delegate it, and optionally merge accounts later to keep things tidy.
• For example, if a staker adds 38.4529 SOL to an account with 5,419.9996 SOL active stake, the additional amount may remain inactive, as seen in a case with a total balance of 5,458.4548 SOL and 38.4529 SOL inactive.

1. Minimum Balance for Rent:

• Each stake account on Solana must maintain a minimum balance to cover rent, a fee to keep the account active on the blockchain. This minimum balance, known as the rent-exempt balance, is always inactive and cannot be used for staking.
• Only the funds above this minimum can be activated and earn rewards, which is a technical requirement to ensure account sustainability.

Impact on Stakers and the Network

Inactive stake has significant implications for both individual stakers and the Solana network:

• For Stakers: Inactive stake means lost opportunity for earning rewards, which can impact passive income. For instance, with a potential missed reward of 2.4994 SOL over 12 months at a 6.5% rate, as seen in one example, the financial impact can be notable. Proper management is crucial to maximize returns.
• For the Network: A high proportion of inactive stake can reduce the network’s security and efficiency, as fewer active stakes contribute to consensus. This is particularly important for Solana, given its emphasis on scalability and high transaction throughput.

Managing and Fixing Inactive Stake

To address inactive stake, stakers have several options, each with pros and cons:

• Using Wallets (e.g., Phantom, Solflare):
• Method: Deactivate the stake, wait for the epoch end (about 2-3 days), and redelegate.
• Pros: Uses trusted tools, straightforward for wallet users.
• Cons: Misses 2-3 days of rewards, potential delays if steps are missed.
• Using Solana Compass Staking Dashboard:
• Method: Connect wallet, withdraw inactive stake, and redelegate via the dashboard (URL: solanacompass.com/validators/EARNynHRWg6GfyJCmrrizcZxARB3HVzcaasvNa8kBS72).
• Pros: Quick fix, keeps stake live, operated by a trusted entity (live since Oct 2021, KYC by Solana Foundation, URL: solana.foundation, stake pools page: /stake-pools).
• Cons: Requires trusting the app, though it has a long track record.
• Using Solana CLI:
• Method: Withdraw excess SOL using commands like solana stake-account YOUR_STAKE_ACCOUNT_KEY and solana withdraw-stake STAKE_ACCOUNT_ADDRESS YOUR_WALLET_ADDRESS MAX_WITHDRAWAL_AMOUNT, then redelegate.
• Pros: Skips cooldown, no reward loss during the process.
• Cons: Requires familiarity with the command line, potentially frustrating for non-technical users. Installation guide available at docs.solana.com/cli/install-solana-cli-tools.

Additionally, if you receive an NFT alerting you to inactive stake (as mentioned by Solanacompass), you can use tools like Sol Incinerator (URL: sol-incinerator.com/#/) to burn the NFT and reclaim the rent fee, ensuring no further inactive stake issues.

Authorized Withdrawals and Technical Details

Stake accounts have an authorized withdrawer address that can withdraw inactive stake, but active stake cannot be withdrawn, adding a layer of security. Technical details, such as merging stake accounts, also play a role:

• Two deactivated stakes can be merged, and an inactive stake can merge into an activating stake during its activation epoch, provided certain conditions are met (e.g., voter pubkey and vote credits observed must match for activated stakes sharing an activation epoch).
• A minimum stake amount for account merging, due to past issues, is at least 1 SOL, sufficient for most cases (related issue: github.com/solana-labs/solana/issues/18942).

Conclusion

Understanding inactive stake on the Solana blockchain is essential for stakers aiming to maximize rewards and contribute to network security. It seems likely that inactive stake arises from activation/deactivation periods, improper management, and rent requirements, with clear methods available to manage and reactivate it. As Solana continues to grow, maintaining an active stake is vital for both individual earnings and the network’s long-term stability.
