Breaking Free from Liquidity Constraints: The Transformative Impact of the iCKB Protocol on Nervos DAO In the blockchain world, liquidity reigns supreme. Recently, the NervDAO staking tool for Nervos DAO integrated the iCKB protocol, marking a significant milestone. This advancement liberates Nervos DAO depositors from the minimum 30-day deposit cycle, effectively addressing liquidity challenges. Moreover, it opens the door to higher yields through “BTCFi Lego.” This article delves into how the iCKB protocol works and its significance in the market. CKB Economic Model, Nervos DAO, and NervDAO Before exploring the iCKB protocol, let’s briefly review the basics of the CKB economic model, Nervos DAO, and its staking tool, NervDAO. As of December 8, 2024, the total issuance of CKB reached 46.202 billion, with 8.133 billion locked in Nervos DAO. These CKB primarily originate from three sources: Genesis Block: Of the 33.6 billion total, 8.4 billion were sent to a "black hole" address (essentially burned) at launch, while the remaining 25.2 billion were allocated to institutional investors, ecosystem funds, development teams, and public investors. These allocations were time-locked but have since fully unlocked. Primary Issuance: A total of 33.6 billion is rewarded to miners, following a Bitcoin-like halving mechanism every four years until fully issued. Secondary Issuance: A fixed annual issuance of 1.344 billion is proportionally distributed among miners, Nervos DAO depositors, and the treasury (currently burned). For a detailed explanation of the CKB economic model, read “A Comprehensive Guide to the CKB Economic Model and Its Elegant Design ( https://t.co/WCg0N3QQ8u ).” Nervos DAO is a smart contract embedded in the system layer, which automatically distributes CKB’s secondary issuance to depositors. Simply put, if holders lock their CKB in the Nervos DAO contract, sacrificing liquidity, they receive compensation to offset asset dilution caused by secondary issuance. NervDAO simplifies staking and withdrawal for Nervos DAO users. Compared to other tools like Neuron Wallet and CKBull Wallet, NervDAO offers: Lower Barriers to Entry: Operate directly on a web interface without downloading additional apps or syncing block data. Multi-Chain Wallet Support: Currently compatible with JoyID, MetaMask, OKX Wallet, UniSat, and UTXO Global Wallet, with future support for ecosystems like SOL, DOGE, and Nostr. With the integration of iCKB, NervDAO users now have two staking options: the "traditional" Nervos DAO staking or staking via the iCKB protocol. iCKB Protocol Explained Developed by community contributor Phroi, the iCKB protocol resolves Nervos DAO's liquidity limitations by allowing users to deposit or withdraw any amount of CKB at any time. How It Works For users, depositing CKB into Nervos DAO through the iCKB protocol is a one-step process: converting CKB into iCKB. Similarly, withdrawals only require converting iCKB back to CKB. iCKB acts as a deposit receipt for CKB locked in Nervos DAO. Currently, 1 CKB ≈ 0.86287995 iCKB, and 1 iCKB ≈ 1.15890975 CKB. Deposited CKB accrues secondary issuance rewards (annualized return ~2.26%), causing iCKB to appreciate over time. The protocol splits deposits into large and small portions, with every 100,000 iCKB-equivalent deposit forming a large deposit. A market maker mechanism ensures liquidity for smaller deposits. Example Alice deposits 300,000 CKB through the iCKB protocol, resulting in: Two large deposits (125,000 CKB each), locked in Nervos DAO. A small deposit (50,000 CKB), handled by the market maker. Alice receives 240,000 iCKB, temporarily escrowed on-chain. An "Extract" operation is required to transfer these iCKB to her wallet, or they will automatically release upon future deposits or withdrawals. Later, Alice withdraws 240,000 iCKB. The protocol burns the large deposit tokens, withdraws from Nervos DAO, and the market maker handles the remaining 40,000 iCKB. Alice receives 300,000 CKB, again in escrow. This mechanism aggregates large deposits for efficient liquidity and uses market makers to handle smaller deposits, ensuring seamless operations. Market Impact The traditional Nervos DAO staking approach faces two limitations: Minimum Deposit: At least 102 CKB (excluding miner fees). Time Constraints: A minimum 30-day lockup and delayed withdrawals depending on reward cycles. The iCKB protocol eliminates these barriers, enabling instant deposits and withdrawals of any amount, vastly improving liquidity. Moreover, iCKB is an RGB++ asset, allowing holders to: Earn Nervos DAO interest. Participate in BTCFi applications for additional yields, such as becoming a liquidity provider (LP) on UTXOSwap. Utilize iCKB across UTXO chains like DOGE via Leap’s bridgeless cross-chain technology. Leverage CKB's Lightning Network (Fiber Network) for low-cost, private, and instant transactions. Usage Guide The NervDAO website offers two staking options: one is the "traditional" staking method available on the Deposit page, and the other is staking via iCKB on the iCKB page. These two methods operate independently. As mentioned earlier, using the iCKB protocol to deposit CKB into Nervos DAO is a straightforward one-step process: convert CKB into iCKB. Similarly, to withdraw CKB, simply convert iCKB back to CKB. Here are the detailed steps: Deposit 1. Open the NervDAO website and connect your wallet (currently supporting JoyID, MetaMask, OKX Wallet, UniSat, and UTXO Global Wallet). 2. Click iCKB in the left navigation bar, select Deposit, enter the desired amount of CKB to deposit, then click the Swap button and confirm the transaction in your wallet. 3. Wait approximately 90 seconds for confirmation. Once the order in the Active Orders section is marked as Completed, it indicates that the on-chain operation has been successfully completed. 4. At this point, your iCKB will be held in an on-chain contract escrow. If you wish to retrieve it, click Extract and confirm the action in your wallet. If you choose not to extract, the iCKB will automatically be released from escrow and returned to your wallet the next time you deposit CKB for iCKB or swap iCKB for CKB. Whether or not you perform the Extract operation does not affect the interest earnings from Nervos DAO. The only difference is that iCKB in escrow cannot be directly swapped back to CKB, transferred to other wallets, or used in BTCFi applications. Withdraw 1. Open the NervDAO website ( https://t.co/W2plzTWXi1 ) and connect your wallet. 2. On the iCKB page, select Withdraw, enter the amount of iCKB you want to swap, then click the Withdraw button and confirm the transaction in your wallet. (Note: If you wish to withdraw all iCKB and there are any iCKB held in on-chain contract escrow under Active Orders, you will need to perform an Extract operation to retrieve all iCKB first.) 3.Wait for the on-chain transaction to be confirmed. When the order in the Active Orders section shows as Completed, the on-chain operation is finished. Similarly, the CKB will be held in an on-chain contract escrow. You can immediately retrieve it by performing an Extract operation, or it will automatically be released from escrow and returned to your wallet during your next swap or deposit transaction. Conclusion The iCKB protocol represents a significant leap forward for Nervos DAO staking tools. It not only resolves liquidity constraints but also offers users flexible investment options and enhanced earning opportunities within the BTCFi ecosystem. With iCKB, users can fully unlock the potential of Nervos DAO and the broader BTCFi landscape.
