Staking allows users to deposit their cryptocurrency into a blockchain network for a defined period, actively supporting its operation and security, and earning rewards in return. While similar to bank deposit interest, staking is unique in enabling holders to directly leverage their crypto assets for income generation.
Traditional mining required high-performance hardware and significant energy consumption, but staking eliminates the need for such equipment and is recognized as a more environmentally friendly approach. Staking also enhances network decentralization and strengthens blockchain security, since broader participation in validation makes it more difficult for any single actor to compromise the network.
Staking participants may be selected as "validators" within the network, taking on these roles and earning corresponding rewards:
The yield from staking is influenced by factors such as overall network supply and demand, the number of participants, and protocol-specific rules. Generally, staking larger amounts increases the probability of being chosen as a validator and earning greater rewards. Yields can also fluctuate significantly depending on network maturity and competitive dynamics, so thorough research is crucial before participating.
To understand why Bitcoin is traditionally seen as "unstakeable," it’s essential to compare Proof of Work (PoW) and Proof of Stake (PoS). These consensus mechanisms underpin blockchain technology, each governed by distinct philosophies and technical features.
PoW blockchains such as Bitcoin rely on computational competition (mining) to validate transactions. Miners dedicate significant computing power to solve cryptographic puzzles, with the first to solve earning the right to create a new block and collect rewards.
This model secures the network via tangible computational effort, delivering robust security. Bitcoin’s protocol only rewards active miners—simply holding BTC does not generate income. This design has underpinned Bitcoin’s reliability and security for many years.
In contrast, PoS chains like Ethereum 2.0 and Cardano select validators based on coin holdings and duration. Network participants stake (lock) their assets to earn rights to create and verify blocks.
Validators receive rewards for honest validation and risk slashing (confiscation) of staked assets for misconduct. By blending incentives and penalties, PoS encourages trustworthy behavior. Importantly, PoS allows holders to contribute to network security and earn yield in proportion to their stake.
Because of these differences, Bitcoin lacks a native staking mechanism. Its network operates exclusively on PoW, with no protocol for asset locking or reward accrual. Nonetheless, many long-term BTC investors seek ways to grow their holdings, and alternative yield strategies beyond mining are gradually emerging.
In short, Bitcoin itself still does not support staking, but new technologies are steadily expanding ways to earn yield from BTC. Innovative projects launched in recent years have made "staking with Bitcoin" a tangible possibility.
These projects leverage layer-2 solutions and cross-chain integrations to offer BTC holders new income opportunities—without altering Bitcoin’s underlying protocol. Notably, Babylon, Stacks, and **Stroom** each present distinct approaches to Bitcoin staking, which are explained in detail below.
| Method / Project | Bitcoin Handling | Yield Source | Reward Type | Expected Yield (Annual) | Main Risk Factors |
|---|---|---|---|---|---|
| Babylon | Locks BTC on-chain for use as collateral on other networks | Partner PoS chain block rewards | Partner chain tokens (e.g., BBN) | Approx. 5% (e.g., 5% target for Maple integration) | Partner token price volatility, BTC slashing for validator misbehavior, protocol bugs |
| Stacks | Does not touch BTC directly; locks STX tokens | BTC paid by Stacks miners | Bitcoin (BTC) | Approx. 3–10% (variable) | STX price volatility, Stacks protocol bugs and economic risk |
| Stroom | Deposits BTC for Lightning Network operations and issues stBTC | Lightning Network fee income | Bitcoin (BTC) | Approx. 1–3% (estimate) | Custody risk, low LN demand, smart contract bugs |
| WBTC + DeFi | ERC-20 conversion of BTC via custody (e.g., WBTC) | DeFi protocol interest and liquidity mining | BTC or protocol tokens | Approx. 1–10% (variable for liquidity mining) | Custody risk, bridge hacks, smart contract risk |
*Yields vary by market conditions and project; the figures above are examples. Advanced protocols that combine multiple methods (e.g., EigenLayer restaking) are also emerging.
Babylon, developed by Stanford researchers, enables direct Bitcoin staking to enhance the security of other PoS blockchains. Built on Cosmos SDK, Babylon operates in tandem with Bitcoin, leveraging its economic value and security for emerging blockchain ecosystems.
With Babylon, Bitcoin holders join the protocol by locking BTC in specialized script addresses. The BTC remains on Bitcoin’s main chain and is never transferred off-chain. This design, which avoids wrapped tokens or pegs, lets users stake BTC directly from self-custody wallets, maximizing transparency and security.
Babylon’s "Bitcoin Secured Network (BSN)" framework allows PoS validators to use their own or delegated BTC as collateral for block production. Using BTC as collateral offers several key benefits:
Users who lock BTC participate in staking on partner PoS chains through Babylon, earning native chain tokens as rewards. These are paid in each chain’s token or Babylon’s own BBN token—not BTC. While users can earn across multiple ecosystems, they are exposed to token price volatility.
Babylon’s most significant technical achievement is implementing PoS-style slashing (collateral forfeiture for misbehavior) directly on Bitcoin. Previously, Bitcoin’s limited smart contract capabilities made such processes difficult.
Babylon solves this using Extractable One-Time Signature (EOTS) cryptography. If a validator acts maliciously (e.g., double-signs), their private key is exposed, allowing third parties to confiscate the collateralized BTC. This innovation enables robust economic penalties on the Bitcoin network for the first time.
Babylon’s mainnet launch drew immediate attention, with its initial staking allocation selling out in just one hour. The second round saw over 24,000 BTC applications, and more than 35,000 BTC staked within a set period—demonstrating intense investor interest.
However, rewards are paid in volatile tokens with no principal guarantee, and misconduct or system failures can result in forfeiture of locked BTC. The Babylon team states that "yield involves risk," so participants must practice robust risk management. If partner chain tokens drop sharply, actual BTC returns may be negative—so caution is warranted.
Stacks operates as a Layer 1 blockchain and Bitcoin L2, utilizing its proprietary "Proof of Transfer (PoX)" consensus mechanism instead of PoS. PoX uses Bitcoin for block creation, with rewards paid in STX tokens.
Stacks miners send BTC to designated addresses when proposing blocks; if selected by lottery, they generate Stacks blocks and earn STX. The BTC sent is redistributed to qualifying STX holders ("stackers"). This mechanism forges a direct economic link between the Bitcoin and Stacks ecosystems, delivering benefits to both networks.
Stackers participate by locking a set amount of STX tokens, qualifying to receive BTC sent by miners as rewards. This is "lock STX to earn BTC," fundamentally different from PoS staking, where rewards are paid in the staked asset.
Main features:
This system allows STX holders to earn BTC without directly holding Bitcoin—a distinctive opportunity.
Historically, BTC-denominated yields have reached around 10% annually, but rates fluctuate with total STX locked and miner participation, and may settle at lower levels depending on market conditions. STX token price volatility is also a risk; if STX drops, the value of locked assets falls, and BTC rewards may not fully offset losses.
Stacks is technically a "Bitcoin Layer 2," supporting smart contracts, NFTs, and DeFi. It expands BTC-denominated application potential and brings new functionality to the Bitcoin ecosystem. However, earning stacking rewards requires buying and holding STX tokens; simply depositing Bitcoin does not earn staking rewards. This is a key difference for users seeking pure Bitcoin staking.
Stroom utilizes the Bitcoin Lightning Network (Layer 2) to generate fee income directly from BTC and issue stBTC tokens usable in DeFi. Similar to Ethereum’s stETH, Stroom aims to provide both "liquidity for locked assets" and "yield from network operations," offering Bitcoin holders a new avenue for asset utilization.
Stroom operates as follows:
BTC Deposit
Users deposit BTC to Stroom, which issues corresponding ERC-20 "stBTC" tokens. BTC is secured by multisignature or custody, and used for Lightning Network channel operations—immediately functioning as settlement infrastructure.
Using stBTC
stBTC is a liquid staking token (LST) backed by real BTC, freely tradable and usable in DeFi. This enables users to lock BTC while still leveraging its value for other investments.
Lightning Fee Accrual
Stroom runs routing nodes, opening channels on LN to provide liquidity. Routing fees are pooled and distributed to stBTC holders. Increased Lightning Network usage boosts fee revenue.
Reward Redemption
Burning stBTC allows users to reclaim their deposited BTC plus interest. As operational profits accrue, stBTC’s value rises, rewarding long-term holders.
Stroom’s annualized yield is estimated around 1–2%, modest compared to other projects. However, BTC must be deposited with a custodian—not self-custody—and returns depend on Lightning Network demand. stBTC’s value and redemption rely on smart contracts, introducing additional risk. Stroom’s design is distinct from fully self-custodied models like Babylon. Participants must carefully evaluate risks such as custodian insolvency or cyberattacks before joining.
Bitcoin-based staking approaches differ from native PoS chains in yield structure, risk profile, and security model. Understanding these distinctions is vital for sound investment decisions.
Yield Structure: PoS chains typically pay rewards in the staked token (e.g., ETH staking yields ETH). Bitcoin staking often pays in other tokens (Babylon: partner chain tokens; Stacks, Stroom: BTC), making yield structures more complex. This complexity complicates return calculations but enables portfolio diversification.
Price Volatility Risk: PoS chains concentrate risk in the staked asset, while BTC staking requires monitoring both BTC and reward token price movements. Falling reward token prices may erode BTC returns, and principal loss is possible—especially with volatile new tokens, so rigorous risk management is essential.
Security Model: PoS chains directly secure their networks via staked assets; BTC projects leverage Bitcoin’s economic power and finality indirectly. Babylon uses BTC for PoS chain finality, Stacks records block data on Bitcoin L1 for enhanced integrity, and Stroom employs the Lightning Network but does not directly affect Bitcoin’s core security.
Slashing and Operational Risk: PoS protocols impose slashing penalties for misbehavior. In BTC staking, Babylon enforces slashing via key exposure, Stacks lacks slashing but requires STX holdings, and Stroom involves custody risk. BTC staking places operational responsibility on the protocol, so users must scrutinize project reliability.
Currently, few Japanese exchanges offer Bitcoin staking. Existing services, such as BTC lending from bitFlyer or GMO Coin, provide interest rates of 0.1–5% per year. Unlike staking, these involve exchanges lending BTC to third parties and paying interest in BTC.
Some PoS coin staking services (e.g., for Ethereum) have emerged, but BTC is technically unsupported. To access projects like Babylon or Stroom, users must participate directly in overseas protocols. Domestic partnerships and new services may develop as regulations evolve.
No clear Japanese law governs BTC staking, but related activities may require financial authority filings and accountability. Currently, intermediaries face legal barriers to brokering protocols like Babylon, necessitating careful preparation and regulatory coordination before service launch.
From a tax perspective, BTC staking and lending rewards are classified as "miscellaneous income." If annual rewards exceed ¥200,000, users must file a tax return. Profits from token sales are taxed as capital gains. Tax liability arises upon receipt of rewards, and with highly volatile crypto assets, "unrealized gain taxation" may occur—taxes are assessed on the value at receipt, regardless of subsequent price declines.
Tokens like stBTC or BBN may also require whitelist registration and legal review before Japanese listing. Legal clarification and market track record are prerequisites for domestic circulation, so overseas usage dominates for now.
Bitcoin lacks native staking functionality, but innovative projects such as Babylon are steadily expanding ways to earn yield from BTC. Stacks and Stroom offer alternative approaches, presenting new asset strategies for long-term holders.
Each project has unique technical features and risk profiles: Babylon enhances other chains’ security while providing rewards; Stacks enables BTC yield by staking STX via its PoX mechanism; Stroom leverages the Lightning Network for BTC operations.
However, these sophisticated designs—often involving smart contracts or custody—carry inherent risks. Asset price volatility, technical challenges, custody risks, and regulatory uncertainties all require thorough understanding and individualized risk assessment.
Looking ahead, regulatory clarity and technological advances may enable safer and more efficient Bitcoin management. Japan may see new services as the legal landscape matures. Investors should objectively weigh yield and risk, selecting strategies aligned with their goals.
Bitcoin itself does not support staking. It is secured by Proof of Work, not Proof of Stake. However, some platforms offer alternative ways to earn yield using BTC.
Bitcoin uses Proof of Work (PoW), so staking is not available. Ethereum has adopted Proof of Stake (PoS), enabling staking. Ethereum staking is more energy efficient and offers rewards.
Bitcoin does not provide native yield, but delta-neutral derivatives strategies—such as arbitraging perpetual futures funding rates against fixed-term futures—can achieve 3–6% returns. Managing risks and choosing transparent methods are essential.
The main risks of Bitcoin staking include loss of funds if the exchange fails, hard forks or security vulnerabilities, and limited liquidity. Using self-custody wallets can help reduce these risks.
