Project Overview Bifrost is a next-generation liquid staking protocol designed to unlock liquidity across multiple blockchains. It allows users to stake native digital assets—such as DOT, ETH, ASTR, and more—while retaining their liquidity through DeFi-compatible derivative tokens called vTokens. By converting staked tokens into vTokens, Bifrost enables users to earn staking rewards while simultaneously participating in DeFi activities like lending, swapping, and yield farming across chains. Bifrost positions itself as a yield layer for Web3, aiming to lower staking barriers, increase asset efficiency, and enable composable, cross-chain capital movement. Solving Staking Liquidity Fragmentation As Proof-of-Stake (PoS) networks become dominant in securing decentralized infrastructure, the staking mechanism has introduced a new problem—liquidity lock-up. On Polkadot, for example, native DOT staking imposes a 28-day unbonding period and removes those assets from productive DeFi use. The broader issue isn’t just illiquidity—it’s fragmentation. Polkadot’s multi-chain architecture is designed for interoperability, yet staking remains siloed per chain. Liquidity from staked assets is isolated and underutilized, leaving vast capital pools dormant across the ecosystem. Bifrost was created to solve this paradox—to bridge the gap between staking and liquidity, and to unify fragmented staking capital under one programmable, composable standard. Through Bifrost’s SLPx architecture, users can mint liquid staking tokens (vTokens) directly on chains like Moonbeam, Astar, or Base, without ever transferring assets to the Bifrost chain. These vTokens remain composable across ecosystems while continuing to accrue staking rewards. Additionally, native staking introduces technical risks and high thresholds. For instance, becoming a Polkadot validator requires staking at least 500 DOT and operating a stable node infrastructure. Even nomination-based staking can lead to slashing if underlying validators misbehave. Bifrost mitigates these risks via proxy staking and a shared slashing insurance pool, offering users a seamless, low-risk liquid staking experience. Architecture & Product Design vToken: Liquid Staking Derivatives At the core of Bifrost is the vToken, a derivative token representing staked assets like DOT, ETH, or ASTR. When users stake through Bifrost: The native asset is staked via Bifrost’s proxy validators; An equivalent amount of vToken (e.g., vDOT) is minted to the user; The vToken continues to accrue staking rewards; The user can trade, lend, or utilize the vToken freely in DeFi. vTokens unlock dual utility—staking yields plus full liquidity. SLP & SLPx: Cross-Chain Yield Routing Initially, Bifrost used an on-chain module called SLP (Staking Liquidity Protocol), which required users to transfer assets into the Bifrost chain for staking operations. To overcome this friction, Bifrost introduced SLPx, a major protocol upgrade that enables remote staking and cross-chain vToken minting. Users can now: Mint vTokens directly on their native chain (e.g., Moonbeam, Astar, Base); Redeem vTokens back to native assets without bridging; Swap between vTokens and native tokens using Bifrost’s centralized liquidity pool on its own chain. This architecture enables “local UX, global liquidity.” Every staking operation feels native to the user’s chain, while liquidity remains unified on Bifrost—reducing slippage, increasing capital efficiency, and preventing liquidity fragmentation across chains. For lending protocols that use vTokens as collateral, this architecture is particularly impactful. During liquidation events, protocols can tap into Bifrost’s centralized liquidity pool to execute cross-chain settlements, ensuring deep liquidity and minimal price impact. Tokenomics: BNC, vBNC, and bbBNC Bifrost implements a layered token economy consisting of: BNC – Native Token Used for paying gas fees on the Bifrost parachain; Powers on-chain governance, allowing holders to vote on proposals and upgrades. vBNC – Liquid Staking Token Represents staked BNC; Continues to earn staking rewards (approx. 5% APY); Retains full governance rights inherited from BNC. bbBNC – Sharing the protocol profit Created by locking vBNC for a specified period; Grants protocol revenue share based on amount and lock duration; Accrues staking rewards via vBNC and adds farming multipliers for enhanced incentives; Holds full governance power in line with vBNC. The combination of vBNC and bbBNC allows users to choose between liquidity and revenue maximization, supporting flexible capital strategies while reinforcing Bifrost’s decentralized governance. Business Model Bifrost generates sustainable protocol income through: Staking Commissions: A share of rewards from delegated staking is allocated to the protocol treasury; Cross-Chain Transaction Fees: Including redemption, swaps, and governance participation; Integration Fees: Collected from protocols leveraging Bifrost’s yield infrastructure; System Staking Yields: Generated by idle assets staked via protocol-owned strategies. These revenue streams feed directly into the Bifrost DAO and are redistributed to bbBNC holders, creating a circular value loop and aligning user incentives with protocol growth. Building the Yield Layer for Web3 In a landscape where staking often means illiquidity, complexity, and fragmented capital, Bifrost delivers a unified, cross-chain liquid staking infrastructure built for composability, efficiency, and scale. Through its vToken standard, SLPx architecture, and layered token economy, Bifrost enables users to access staking rewards without compromising on liquidity—and developers to build on a seamless, chain-agnostic yield layer for digital assets. As the largest liquid staking protocol in the Polkadot ecosystem and a growing force across Ethereum and Layer 2 networks, Bifrost is positioning itself as a core liquidity router for multichain DeFi, bridging the gap between idle capital and yield-generating opportunity.

What is Liquid Staking? Liquid staking is an innovative method in decentralized finance (DeFi) that allows cryptocurrency holders to earn staking rewards while maintaining liquidity. Traditionally, staking DOT, Polkadot’s native cryptocurrency, required locking tokens for a set period, limiting users’ ability to trade or use these tokens elsewhere. Liquid staking solves this issue by providing tokenized representations of staked assets. How Does Polkadot Liquid Staking Work? When users liquid stake DOT, they deposit their tokens into a staking protocol that issues a tokenized derivative (often called Liquid Staking Tokens or LSTs), such as vDOT. These derivative tokens represent the user’s staked voucher and accrue staking rewards automatically. Users can freely use these tokens in other DeFi protocols or trade them, enhancing capital efficiency. Benefits of Liquid Staking DOT 1. Enhanced Liquidity Liquid staking allows holders to retain liquidity while staking DOT. Tokenized derivatives like vDOT can be traded freely on decentralized exchanges like Hydration. 2. Continuous Rewards Participants receive staking rewards continuously and automatically. As staking rewards are received, vDOT increases in value, without any change to the quantity of tokens. 3. Increased Capital Efficiency Users can use liquid staking tokens in other DeFi activities such as lending, borrowing, or providing liquidity in liquidity pools. 4. Flexible Unbonding Time Unlike traditional staking methods requiring 28 days of unbonding periods, liquid staking allows immediate access to tokens via derivatives. Bifrost: Best Liquid Staking Platform For Polkadot Staking Bifrost leverages Polkadot’s native security and decentralized infrastructure. With a solid foundation already in place, Bifrost has surpassed $60M in TVL and now dominates over 67% of liquid staking market on Polkadot. How Does vDOT work? Unlike other liquid staking solutions, Bifrost employs a dedicated account to manage the unstaking queue. This design ensures that unstake requests are not restricted to batching in each ERA. For instance, when a user initiates an unstake request for vDOT and no DOT is currently available in the unstake queue, the system will trigger an on-chain request to begin the standard 28-day unbonding period. However, if another user subsequently deposits a large amount of DOT—say, 10,000 DOT—within that period, Bifrost can immediately fulfill the original unstake request using the newly deposited assets. This mechanism allows users to bypass the 28-day waiting period entirely. Remarkably, the total fee for this advanced service is only 0.1%. How to Liquid Stake DOT on Bifrost Login to app.bifrost.io and confirm the network is Polkadot Click on vStaking in the main navigation menu, then click vDOT to enter the vDOT page Enter the amount of DOT to be minted into vDOT in the right panel (0.5 DOT is the minimum) Click on “Stake” button, confirm and sign the transaction. Once vDOT are minted they are directly deposited in the “Wallet” tab vDOT Use Cases Hydration Money Market On Hydration, users can employ a looped strategy by depositing vDOT as collateral to borrow DOT, swapping the borrowed DOT for additional vDOT, and repeating the process. This recursive mechanism allows users to amplify their exposure to staking rewards and optimize capital efficiency. Interlay Lending Market vDOT can be utilized as collateral on Interlay’s money market, enabling users to borrow assets such as DOT or iBTC. Borrowing DOT allows users to restake and mint additional vDOT, effectively compounding their staking position. Alternatively, borrowing iBTC provides access to a broader range of yield-generating strategies within the DeFi ecosystem, expanding the utility of vDOT across multiple protocols. Polkadot OpenGov vDOT holders retain full governance rights within the Polkadot OpenGov system. By staking DOT to mint vDOT, users maintain their ability to participate in governance without forfeiting yield. This also underscores Bifrost’s commitment to neutrality and non-custodial participation in network governance. Conclusion Liquid staking DOT presents an attractive alternative to traditional staking by combining liquidity and staking rewards. While offering significant advantages such as enhanced liquidity and capital efficiency, users must remain aware of inherent risks. Always perform thorough due diligence when choosing a liquid staking provider. By understanding these aspects, investors and users can effectively leverage liquid staking DOT to optimize their DeFi strategies.

As one of the most influential projects in today’s blockchain landscape, Polkadot’s staking mechanism and token economics have garnered significant attention. Many community members and DeFi users seek ways to earn attractive staking yields while maintaining liquidity for their assets. In this article, we will walk through the topic from foundational concepts to advanced technical analysis, covering: How Polkadot’s staking (NPoS) works and how rewards are calculated. The relationship between staking yields, inflation models, and network security. How Bifrost’s liquid staking (vDOT) operates, and how it compares to traditional staking. How the decentralized exchange Hydration empowers liquidity and trading scenarios for staking assets like vDOT. Polkadot’s NPoS Mechanism and Reward Calculation Polkadot adopts a Nominated Proof of Stake (NPoS) model to maintain network security. There are two key participants: Validators: Node operators who produce blocks and validate transactions by locking a significant amount of DOT as collateral. Only validators with sufficient nominations from nominators can join the active validator set (currently capped at around 300). Nominators: Regular DOT holders who stake (nominate) their tokens to trustworthy validators, increasing the validator’s weight in elections. Nominators share the validator’s rewards proportionally and play a critical role in network security. In this system, staking rewards mainly come from newly minted tokens (inflation) and a small portion of transaction fees. Here’s how rewards are calculated and distributed: Block Reward Distribution: After producing a block, a validator earns a set amount of DOT as a reward. This reward is shared among all nominators proportionally based on their stake, after deducting the validator’s commission. For example, if a validator has a 5% commission and earns 10 DOT, 0.5 DOT goes to the validator, and the remaining 9.5 DOT is distributed among nominators according to their share. Example: Suppose two nominators contribute 70% and 30% of the total nominations, respectively. After the 5% commission is deducted, the first nominator would receive 6.65 DOT, and the second would get 2.85 DOT. Eras and Compounding: Polkadot operates on ~24-hour cycles called Eras. Rewards are settled at the end of each Era, but they do not automatically compound. Users must manually claim or re-stake their rewards to maximize growth. Some staking services and liquid staking protocols automate this process. Through NPoS, DOT holders can earn passive income by nominating validators, while validators are incentivized to maintain honest and stable operations to avoid slashing and continue earning rewards—a win-win economic model that enhances network security. Staking Yields, Inflation Model, and Network Security Polkadot’s tokenomics are designed around a dynamic inflation model to balance network security and token liquidity. Initially set at ~10% annual inflation, Polkadot has adjusted its inflation rate down to 8% by the end of 2024, with plans for gradual reduction. Newly minted tokens are distributed between stakers and the treasury. Critically, reward distribution dynamically adjusts based on the network’s overall staking rate, targeting approximately 50% of all DOT staked: When the staking rate is low, staking rewards increase to incentivize participation. When the staking rate is high, staking rewards decrease, redirecting more inflation to the treasury and encouraging some stakers to exit. For example: At 10% staking, the theoretical annualized staking return could approach 100% to rapidly attract stakers. At 50% staking, stakers would share the 8%-10% inflation evenly, resulting in an annual yield of around 16%-20%. If staking exceeds 50%, returns drop sharply, following an exponential decay curve. Near 100% staking, yields could fall to as low as 2.5% annually. This design carefully balances security and liquidity: With 50%-60% staking, the network remains economically secure (making attacks prohibitively expensive), while enough DOT remains liquid to fuel parachain auctions, DeFi activities, and trading. Importantly, governance can fine-tune inflation parameters over time. But the core incentive curve ensures that active stakers maintain their proportional share of the network against inflation, while non-stakers face gradual dilution. Thus, Polkadot’s staking economics drive sufficient token locking for security while avoiding liquidity shortages that could hinder ecosystem development. Bifrost Liquid Staking: How vDOT Works Despite Polkadot’s attractive staking returns, traditional staking locks tokens for 28 days during the unbonding process, limiting flexibility. To address this, the ecosystem developed liquid staking protocols—and among the most prominent is Bifrost. Bifrost is a Polkadot parachain focused on providing liquidity for staked assets. Here’s how its vDOT liquid staking model works: Staking and vDOT Minting: Users stake DOT through Bifrost, and ~90% is actively staked on Polkadot. Simultaneously, users receive vDOT at a 1:1 ratio representing their staked assets. Reward Accumulation: Staking rewards increase the redemption value of vDOT over time. For example, if staking yields 20%, the 1 vDOT could eventually redeem 1.2 DOT. Fee Structure: Bifrost charges a 10% commission on staking rewards. The remaining 90% benefits vDOT holders. Liquidity and Redemption: Users can trade vDOT freely on secondary markets, use it in DeFi, or redeem it for DOT. While full redemption requires the Polkadot unbonding period, Bifrost maintains liquidity buffers to enable instant small withdrawals. Otherwise, users can sell vDOT immediately on DEXs, subject to market conditions. Risk Management: Risks like validator slashing or smart contract bugs exist, but Bifrost uses diversified validator nominations, insurance reserves, and arbitrage incentives to mitigate systemic risks. Advantages Over Traditional Staking Instant Liquidity: vDOT holders can exit positions at any time without waiting 28 days. Auto-Compounding: vDOT automatically accrues staking yields, eliminating manual restaking. DeFi Integration: vDOT can be used as collateral, provided as liquidity, or leveraged across DeFi ecosystems to generate additional yield. While yields via vDOT may be slightly lower (12%-13% vs. 15%) due to fees and unstaked reserves, the added flexibility and earning potential across DeFi platforms often more than compensate for this difference. Hydration: Empowering Liquidity for Staked Assets Having liquid staking tokens like vDOT is just the first step—efficient liquidity markets are crucial for maximizing their utility. Enter Hydration, an all-in-one DeFi platform rising as Polkadot’s liquidity hub. Key Modules: Omnipool: A single-sided liquidity AMM, allowing users to supply vDOT, DOT, or stablecoins individually into a shared pool. vDOT and DOT are efficiently traded within the same pool, keeping prices tightly pegged with minimal slippage. As of now, 690,000+ DOT and 560,000+ vDOT are pooled with deep liquidity. Polkadot’s treasury allocated 2 million DOT to bootstrap liquidity, with initial LP incentives reaching 200%+ APY. Money Market: Hydration’s decentralized lending platform allows vDOT to be used as collateral to borrow DOT or stablecoins. This enables leverage staking strategies: Stake DOT → mint vDOT → borrow more DOT → stake again, amplifying yields (with risk management). Within just 15 hours of launch, Hydration’s vDOT supply cap was fully utilized—reflecting strong market demand for leveraging staking derivatives. Benefits: Instant Liquidity Exit: Sell vDOT on DEX without waiting 28 days. Arbitrage Opportunities: Traders stabilize vDOT/DOT pricing via redemption arbitrage. Secondary Yield: Provide liquidity, lend vDOT, and earn additional rewards. Capital Efficiency: “One asset, multiple use cases” through staking + DeFi. Overall, Hydration fully activates the liquidity potential of staking assets like vDOT, making Polkadot’s staking ecosystem more dynamic, efficient, and user-friendly. Yield Model Comparison: Traditional Staking vs. Liquid Staking To illustrate the differences, consider staking 100 DOT for one year: Staking Method Annual Yield Liquidity Access DeFi Usage Total Return Potential Traditional Staking ~15% Locked 28 Days No Basic Staking Rewards Liquid Staking via vDOT ~12%-13% Instant / Market Yes Staking + DeFi Earnings While the base yield via vDOT is slightly lower, the combined yield from DeFi activities (liquidity mining, lending, etc.) can significantly outperform traditional staking returns under active management. Thus: Passive DOT holders may prefer traditional staking. Active DeFi participants or those valuing flexibility and capital efficiency are better suited for liquid staking strategies. With the maturity of platforms like Bifrost and Hydration, liquid staking is becoming the mainstream approach for maximizing returns and utility within the Polkadot ecosystem.

What is Bifrost Bifrost is a liquid staking appchain tailored for all chains, currently supporting Ethereum and Polkadot chains. The ultimate goal of Bifrost is to enable the minting of any Liquid Staking Token (LST) on any blockchain. The flyweel: Bifrost Tokenomics BNC is the native token of Bifrost, with a total supply of 80,000,000 tokens. Initially, BNC was mainly used for governance. However, in 2024, Bifrost upgraded a new tokenomics proposal, where 100% of the protocol’s profits will be used for BNC buybacks. 90% of the buybacks are distributed to bbBNC holders, with the remaining 10% burned. Users can liquid stake BNC to receive vBNC (BNC LST), then lock vBNC to receive bbBNC. The more vBNC you lock and the longer the lock duration, the more bbBNC you can earn. In 2024, Bifrost’s total protocol revenue reached $7,926,900, with gross profit of $1,695,300. You can check real-time protocol revenue and profits on Bifrost Stats. Keep your eyes peeled for the new tokenomics launch – this train’s leaving the station soon! 🚂 Most Popular Product: Bifrost vToken vToken, the voucher of staked token, is a liquid staking token issued by Bifrost. Currently, Bifrost supports 9 assets: vDOT, vKSM, vETH, vBNC, vASTR, vMANTA, vPHA, vGLMR, and vMOVR. vTokens are yield-bearing assets. Holding vTokens allows you to enjoy staking rewards while maintaining liquidity, providing a “hands-off earning” approach. The longer you hold, the more native tokens your vToken can redeem. For example, with BNC, the initial minting rate for vBNC/BNC is 1:1, meaning 1 BNC can mint 1 vBNC. However, after holding 1, this 1 BNC generates rewards, so it increases to 1.01 BNC. Therefore, your 1 vBNC can be redeemed for 1.01 BNC, and the extra 0.01 BNC is the staking reward. Since the vBNC/BNC ratio changes over time, when another user mints vBNC, 1 BNC will only mint around 0.99 vBNC. This ensures fairness for every mint or redemption at any given moment. How to start your Liquid Staking journey on Bifrost? You can experience liquid staking on Bifrost Dapp or Omni.ls. Bifrost supports mainstream wallets and is compatible with both Substrate and EVM addresses for liquid staking.

Staking allows us to secure rewards by locking up a specified amount of tokens, but its benefits extend far beyond simple financial gain; they allow us to actively take part in ecosystem governance decisions by actively taking part in its decision-making processes and helping shape its development and security. In this article, we’ll learn what is Polkadot staking and why should we stake. Nominated Proof of Stake (NPoS) Polkadot blockchain was launched by Gavin Wood in 2016. Polkadot employs the Nominated Proof of Stake (NPoS) mechanism, consisting of two roles - “validators,” who operate nodes; and “nominators,” who nominate validators to operate their machines on behalf of others and can still earn rewards through this system. Nominators can also join a nominator pool to further reduce barriers to participation and streamline operational procedures. Polkadot uses Network Proof of Stake (NPoS) technology which requires only 10 validators per parachain; so with 100 parachains there will only ever need 1000 validators total! Currently the Polkadot network boasts 297 validators but they hope to reach this target goal during its mature stage; Polkadot’s “Thousand Validators Initiative” seeks to reach this goal and increase number. Polkadot currently holds 874 million DOT staked at an approximate stake rate of 58%; there are 36,800 nominators with the historical staking yield post commission deduction being 14.86% with an inflation rate of 9.83%. PoS chains typically see increasing participation and therefore higher stake rates with greater participation increasing the staking rate, creating more secure networks. Polkadot’s ideal staking rate should be 50%; however, actual rates have typically ranged between 55%-60% over time. DOT Unstaking Period Polkadot’s current lock-up period for staked DOT is 28 days, meaning staked coins can only be unbound after this amount of time has elapsed. While this extends security of the protocol and makes staking less attractive due to reduced flexibility and higher opportunity costs. With RFC 97 proposal’s approval by Fellowship, unbonding time will be shortened from 28 days to 2 days; necessary code or design changes have already been merged into github; implementation by developers will begin shortly thereafter. Four Staking Methods on Polkadot Polkadot natively supports four methods of staking that range in terms of capital requirements: running a validator, direct nomination, operating a nomination pool and joining one (with minimum participation requirement of only 1 DOT). Running A Validator: Running a Validator requires accessing the internet on a full-time basis from a dedicated computer, along with knowledge of technical operations related to validator management. In order to qualify as an active validator set either personally or nominatively stake DOT; currently this amount stands at at least 3 million DOT Becoming A Nominator: must nominate up to 16 validators they trust by staking DOT under them, then divide network rewards equally between themselves and them (current average commission is around 2%) while giving each validator their share (network rewards are split at 60% each); validators pay their commission (current average is 2%) directly while nominators incur financial penalties should any nominated validator engage in misconduct such as going offline; nomination rewards require bonding amounts that fluctuate, currently around 250 DOT. Running a Pool: Nominating pool is a recently introduced feature designed to reduce entry barriers for nominators, providing multiple small nominators an avenue of nominations at once and share rewards and penalties proportionate to how much of their staked shares they own in total. Operating one requires selecting validators as part of your group, with starting an operational nomination pool currently costing 500 DOT. Joining a Nominating Pool: Joining a nominating pool is one of the simplest forms of staking; this requires only 1 DOT to participate and gain rewards through it. Polkadot offers more native staking options with only 1 DOT required as the minimum stake required, further lowering financial and technical entry barriers and encouraging wider participation, thus strengthening decentralization and security on its network. Liquid Staking on Polkadot Due to the lock-up period required by staking, staked funds become unavailable for use; hence liquidity staking has emerged as an alternative solution. Liquidity Staking Tokens (LSTs) provide users with opportunities to earn staking rewards while keeping funds liquid thereby improving capital utilization and utilization rates. By placing tokens into a liquidity staking protocol, users can generate derivative tokens that serve the same purposes as original ones (participating in DeFi) while earning rewards as part of liquidity staking’s ecosystem-boosting qualities. Therefore, its presence stimulates economic activity within PoS chains by giving users simultaneous benefits from both activities; hence liquidity staking is an integral component. Bifrost is currently the top liquid staking platform on Polkadot, having introduced the liquid staking token vDOT for use. At present, 8.45 million DOT have been staked with a total value locked of $39.41 million representing all assets staked. vDOT can generate yields through staking yields as well as lend and farm protocols within DeFi to create multiple streams of income. Bifrost recently introduced Loop Stake, an advanced leverage staking product specifically tailored towards digital tokens such as DOT that allows users to set and manage leverage according to individual risk profiles. Since releasing it for public testing in April 2018 this has already attracted 120,000 DOT in supply as well as nearly 100,000 in borrowing demand demonstrating initial market success at scale and activity levels. Polkadot OpenGov governance requires strong stakeholder representation for successful operation; vDOT can ensure this right remains with them. Polkadot currently boasts 874 Million DOTS staked, which compares favorably with Ethereum in terms of penetration rate of liquidity staking market within its ecosystem. Polkadot offers significant potential growth potential when it comes to liquidity staking market within its ecosystem.

Since blockchain’s creation, developers have faced an insurmountable “trilemma”. It has proven difficult to produce a platform which excels simultaneously at security, decentralization and scalability - an arduous feat indeed! Appchains were once seen as the panacea to scaling problems; they allow multiple chains to interoperate seamlessly while decreasing transaction load on individual chains while still upholding security and decentralization without compromise. But over time appchains have fallen behind other solutions: Layer 2 (L2). Recently discussions around L2 have intensified; rollups now being seen as key ways of reaching scaleability while maintaining security and decentralization simultaneously. Developers who utilize appchains believe they offer unique value propositions, from using native tokens of dApps as payment to internalizing MEV (Miner Extractable Value) within blockchain solutions that generate revenue for them directly - creating more user engagement than L2 solutions ever could and generating revenues through MEV (Miner Extractable Value). Thus while L2 solutions have become the focus of attention recently, appchains will never go extinct! What Is MEV? Maximum Extractable Value, more commonly referred to as MEV, allows miners and validators to extract more value from blockchain through manipulating transaction placement in blocks. Historically this has led to negative behaviors like preemptive trading or sandwich attacks but good MEV strategies such as arbitrage clearing are key parts of making DeFi more efficient. Developers of decentralized applications (dApps) may find having their own blockchain provides greater control of MEV, helping reduce malicious behaviors while at the same time increasing revenue for themselves as an independent dApp developer. As crypto matures and grows into new frontiers of investment and commerce, building profitable and sustainable businesses becomes even more critical to success. MEV could become the driving force for further application chain launches in the future. Who Can Benefit From MEV? Though MEV can provide exciting revenue enhancing possibilities, not every crypto project stands to benefit. MEV can truly benefit DeFi projects that specialize in clearing and arbitrage such as lending protocols, AMMs and perpetual DEXs; such as lending protocols, AMMs or perpetual DEXs that rely heavily on clearing/arbitrage dynamics like lending protocols/AMMs/PERpetual DEXs/perpetual AMMs etc if these projects were simply to launch on L1 or L2, such as lending protocols/AMMs/PERPETUAL DEXs etc; by simply using L1 and/or L2 for launch they would miss out on revenue altogether so it might be wiser for them to launch their own app chain so as to differentiate themselves from competition; for instance dYdX decided against Ether and created its own application chain using Cosmos as its foundation - an example which would suit well here! MEV may not be appropriate if your application involves decentralized services like NFT or GameFi. L1 may provide more cost-efficient and simpler launching solutions - something Helium decided upon after switching their blockchain solution over to Solana. Why Do We Need AppChains？ Beyond MEV, developers may also seek other reasons to launch their own appchains. Transaction Fees and User Experience Transaction fees on L1 chains present one major hindrance for non-crypto native users, making transactions confusing and cumbersome. Appchains offer developers an effective solution by enabling users to pay fees with their native token (dApp’s native token or even gas free transactions), significantly streamlining user experiences and improving overall experience. Scalability Needs L2 solutions may have garnered much praise for their scalability; however, appchains also can provide superior scalability solutions. Gaming-focused apps require high transaction throughput with low latency for optimal operation - for instance FIFA Ultimate Team generates thousands of transactions each second that even L2 solutions find hard to manage efficiently; such games could become ideal candidates for adopting appchains as an efficient scalability solution. Customizability and Adaptability Launching an application chain gives dApp developers greater freedom in customizing the network’s design, consensus mechanism, governance structure, and economic model to suit their application’s exact specifications. While L1 chains should meet most general-purpose dApp needs, some niche applications may need certain protocol level modifications that need to be addressed specifically using appchains; with them developers can customize the network to their exact requirements. Appchains on Polkadot Network Polkadot, created and launched by Gavin Wood - co-founder of Ether - in 2016, provides developers with an interoperable blockchain network with shared security that enables interchain interaction through dedicated ‘Parachains’ connected via a central relay chain (relay chain). These Parachains may interact via central hub relay chains as communication tools between their parachains. Each parachains can use its own consensus mechanism, virtual machine and governance structure for maximum flexibility and customization for developers. Polkadot also offers a shared security model which enables smaller parachains to benefit from the security offered by larger networks. Bifrost - The Liquid Staking Appchain Bifrost is a dedicated modular Liquid Staking L1 secured by Polkadot and built with the Polkadot SDK. The easiest way to understand Bifrost is to see it as a derivative issuer that provides liquidity for all staked assets, issuing corresponding shadow assets during the bonding period of the original assets. At the same time, the shadow asset is a fungible Token that can be circulated in different DEXs, pools, protocols and across chains. Bifrost’s solution vToken (liquid staking voucher Token) enables users to convert their PoS tokens into vTokens in order to obtain staking liquidity and staking rewards synchronously, without barriers in cross-chain scenarios.

Web3 has experienced rapid expansion over the years, as an explosion of blockchain applications have necessitated more scalable solutions to become ever more urgent. AppChain has emerged as an industry buzzword to refer to interoperable blockchain networks designed specifically to offer more scalable, efficient, and flexible infrastructure for decentralized apps (dApps). In this article, we will look into what AppChains are, their advantages, current AppChain projects being undertaken as well as future prospects of AppChains. What Is Appchain? Appchain (Application-Specific Blockchain) is a type of blockchain platform tailored for operating specific applications with unique requirements, providing customized functionality which enhance performance, scalability and effectiveness for specific use cases. Compared with conventional blockchains which exist as one size-fits-all platforms. Appchain provides tailored features which improve performance, scalability and the effectiveness of specific use cases by meeting them more precisely than its traditional counterparts do. Appchains v.s Blockchains Appchains and Blockchains both represent decentralized on-chain technologies; however, their purposes, designs, and functionalities vary considerably; Appchains often having one purpose while Blockchains having many more. Purpose: Appchains typically focus on specific applications that meet targeted use cases while Blockchain platforms offer support for an assortment of uses cases and transactions. Customization: Appchains offer highly tailored customization that caters specifically to project needs, while general-purpose Blockchains generally adhere to standardized protocols with one size fitting all approach. Performance and Scalability: Appchains are optimized to achieve peak performance within their domain, adeptly handling any scalability challenges facing their application(s). On the other hand, general-purpose Blockchains may face difficulties scaling to handle various uses cases. Interoperability: Many appchains feature inbuilt interoperability capabilities for seamless interaction with other systems; on the other hand, connecting different general-purpose blockchains often requires additional efforts or workarounds requiring extra layers or bridges to connect them together. Blockchains provide an extensible foundation for decentralized applications, while Appchains specialize in offering highly targeted, performance solutions tailored specifically for individual project requirements, providing more focused optimization capabilities. An Overview of AppChain Protocols AppChains can be created through several blockchain networks that offer unique benefits for developers: Polkadot Parachains: Connect multiple blockchains to a central Relay Chain to enhance validation, with customizable governance and economic models, native token support, customizable token distribution mechanisms and limited to 100 Parachains in total - though no smart contract functionality exists on Relay Chain itself. Polygon Supernets: Leveraging Ethereum’s security and Polygon Edge’s flexibility to build EVM-compliant blockchains that feature dedicated validators, flexible consensus models, customization features and extensive interoperability support. Cosmos Zones: Utilizing a hub-and-spoke model, application chains connect to the Cosmos Hub for data and token exchange. Key advantages include Tendermint Core for fast transactions, Cosmos SDK development for development purposes and governance by top 100 ATOM holders. Avalanche Subnets: These three chains with various functionalities support L1 or L2 blockchain subnets that use $AVAX for staking. Utilizing Snowball consensus algorithm for fast transactions and high scalability. Each blockchain network offers unique benefits when developing AppChain projects, meeting various project specifications and scaling needs. The Benefits of AppChain More developers are opting for AppChains over smart contracts when managing shared block spaces for three key reasons. High Performance As DApps vie for block space on the same network, popular DApps may consume significant resources that cause transaction costs and network latency to increase for other DApps like Polygon or Arbitrum. AppChains enable project teams to predict transaction costs and network latency within predictable ranges for increased end user satisfaction. Customization As DApps grow into larger markets, developers need to continue improving the products for users. Larger applications must balance various design considerations such as throughput, finality, security levels, permissions, composability and ecosystem coherency when considering design considerations. Validators typically impose high performance demands upon hardware (for instance running SGX and FPGAs to generate zero-knowledge proofs). AppChains provide traditional institutions a way into Web3 without immediately taking an entirely permissionless approach. Companies, for example, can require validators to undergo KYC; prescreen engineers who wish to build applications on their network; and select starting/ending points for cross-chain interactions. Value Capture While general-purpose scaling solutions reduce transaction costs while upholding security and providing developers with a satisfactory experience, these do not offer them many opportunities to capture additional value. Existing products demonstrate strong commercial viability of AppChains, enabling developers to fork existing protocols within other ecosystems and generate income (for instance fees from AMM mechanisms or NFT transactions). AppChains would allow mods to expand these games’ IP by expanding it onto rollups, thus sharing block space economically while reaping other economic advantages. AppChains face challenges as well. Here is what to keep in mind while considering using AppChains: Resource Wastage AppChain can become resource waste if applications don’t utilize all their potential resources on-chain. With validators dedicated specifically for AppChains, any excess resources could be deployed towards supporting other ecosystems instead. Additional Development Costs AppChains development differs significantly from that of smart contracts in that their development involves multiple steps with technical difficulties in managing infrastructure (validators or sequencers) becoming even greater than when working on contracts themselves. Limited Ecosystem Tools and Technical Support There are currently no “ready-made” resources such as block explorers, RPC providers, indexers, oracles, fiat gateways and ecosystem funds that exist as “off the shelf.” The Emerging Market of AppChains Due to their inherent downsides in creating independent ecosystems, AppChains may be better suited for applications possessing certain characteristics: Attaining scale in terms of user base, protocol revenue, TVL (Total Value Locked), product-market fit or other measures of success; or 2. Showing significant product or performance advantages within their dedicated blockchain space. Needing lower security and indivisibility levels; such as P2E games, NFTs, or crypto social platforms. Conclusion As Apple is often associated with offering superior user experiences, blockchain developers can take a similar route by harnessing AppChains for Web3 applications development. AppChains may not always be appropriate. Engineers should carefully consider what needs their applications have before investing time or resources into development. Further, many factors can have a substantial effect on an economic security model’s security model, monetization strategies, platform defensibility and natural growth of stack value as well as any secondary effects it might have on crypto market structures. We look forward to watching AppChains develop in coming years!

Liquid Staking Tokens (LSTs) are tokens issued by staking service providers as DeFi products that represent native tokens on Proof-of-Stake blockchains. Liquid staking tokens allow people to earn rewards while being able to trade or leverage these tokens, providing greater liquidity. Since Ethereum shifted from PoW to PoS mechanisms, validator nodes must stake an agreed upon amount of tokens in order to participate and earn block rewards and staking incentives; this process may not be easy or accessible for ordinary users who seek participation. Challenges Associated with Traditional On-Chain Staking High Minimum Requirements: Public chains often impose strict minimum stake amounts - for instance, Ethereum requires at least 32 ETH per node which raises an entry barrier significantly. Long Staking Periods: Retail investors who opt for long staking periods often become inefficient due to inefficiency due to lock-up periods. Technical and Hardware Requirements: Staking requires specific knowledge as well as hardware that might make the experience user unfriendly if attempted by average participants. The Rise of LST with Ethereum’s Shapella Upgrade The Ethereum Shanghai (Shapella) upgrade, which enabled staking withdrawals, marked the beginning of the rise of Liquid Staking Tokens (LST). LSTs provide ordinary users with new opportunities for token earnings while unlocking liquidity of staked assets - leading to various DeFi strategies including Restaking protocols as well as rapid expansion and broad participation within DeFi ecosystem. LST Mechanism: How Does It Work? When tokens are staked, they are typically locked up for a period, making them unavailable for trading or withdrawal. However, Liquid Staking Tokens (LST) change this dynamic by allowing users to stake assets and unstake them without affecting the initial deposit. The deposit is locked on the liquid staking platform, and a tokenized version of that crypto asset (a liquid token) is issued to the user. These liquid tokens hold the same value as the user’s deposit and are pegged one-to-one to the original staked assets. These tokens have various names to easily distinguish them. For instance, when depositing 1 $ETH into Bifrost’s liquid staking service you receive $vETH as a liquid token which can later be traded or used as collateral on various DeFi platforms. To redeem staked ETH, all that’s necessary to unlock it is returning or exchanging vETH back for real ETH on DEX and then your initial deposit amount will be unlocked. This mechanism enables users to profit from trading liquid tokens while still earning stake rewards from their initial deposit. Types of Liquid Staking Tokens Most liquid staking protocols use one of three token models when conducting liquid stakes: Rebasing tokens Reward-bearing tokens Wrapped tokens Rebase Tokens These tokens automatically adjust their balance based on deposits and rewards received through deposits and rewards deposited, known as rebasing; typically occurring daily. Examples of rebase tokens are Lido’s stETH and Bifrost’s vETH which both belong to this category of LST; both aim to offer user-friendly experiences by increasing your LST balance with every staked activity undertaken by its holders. Example: Staking 100 ETH on Lido would yield 100 stETH. After one week, with an annual rate of 3.5%, your stETH balance should be approximately 100.067 stETH. Reward-bearing Tokens These tokens increase in value and rewards over time as the exchange rate between the native token and the liquid staking token will change. The number of LSTs remains the same, but their exchange rate varies. This single-token model is convenient but more complex than rebase tokens. Holders benefit from the increase in rewards, with examples including rETH, cbETH, swETH, and vETH. Example: Staking 100 ETH on Bifrost would yield approximately 92.9 vETH. After one week, the vETH amount remains the same, but its value would be around 100.076 ETH (based on the current annual rate of 3.96%). Wrapped Tokens Some LSTs feature wrapped versions, which prevent automatic balance adjustments from taking place and become reward-bearing tokens instead. In comparison to rebase tokens, balance adjustments for wrapped tokens such as Lido’s wstETH become increasingly popular due to higher transaction volumes and the absence of any rebase effects on exchange rates. Rewards are integrated directly into exchange rates; rewards integrated directly into their exchange rates make these LSTs especially well suited for DeFi and trading operations. Example: Wrapping 1000 stETH would yield approximately 900 wstETH. After one week, the wstETH amount remains the same, but its value would be around 1000.67 ETH (based on the current APY of 3.5%). For stETH holders, rewards are directly paid into their wallet, potentially subjecting them to income tax as income is generated directly in this manner. Conversely, in case of rETH token holders, rewards accumulate through token value appreciation until finally sold and taxed accordingly upon sale of token. Users looking to gain stETH or rETH can either deposit their Ethereum on Lido or Rocketpool websites or exchange it at DEXs such as Uniswap. Benefits of LST for Staking Activities Promotes and Encourages Staking Activities LST provides a unique solution by creating tokenized derivatives of staked assets, increasing staking activities as stakers can rest easy knowing they will receive derivative tokens that can be used for lending and trading whenever they stake assets - creating more secure networks overall. Multiple Sources of Income With LST, stakeholders can entrust funds or assets on a platform and continue using tokenized versions or derivative tokens as collateral against crypto-backed loans at higher interest rates to boost ROI returns. Risks Associated with LST Slashing Slashing is used to monitor validator misconduct (such as double-signing and validator downtime ) through validators (nodes or individuals that process and validate transactions on the blockchain ). When violations of rules such as double signing occur, or when someone violates them unknowingly through misuse, an amount of tokens belonging to each validator involved are taken off them regardless of intent - for any misconduct found, regardless of intent. Smart Contract Risk Another risk associated with blockchain technology is smart contract risk. While we generally consider blockchain to be secure, vulnerabilities sometimes do exist that attackers could exploit to access and misuse user funds and assets. Loss of Liquid Staking Tokens Users that lose tokenized assets or liquid staking tokens during transactions or trades could unknowingly staked funds that can never be recovered without making another deposit of equivalent size to recover these staked funds. Understanding both the advantages and risks associated with LST are integral for users seeking to optimize returns while developing an efficient staking plan.
