With BTC surpassing 120000, research on BTC projects has recently begun. I just saw that the first phase of the Golden Sats Campaign has started, with a plan of three phases of tasks within two months. Let's talk about @ rootstock_io first. It's not a new chain, nor is it a copy of Ethereum. It is actually the smart contract layer of Bitcoin, which was launched as early as 2018 and is currently the longest running Bitcoin sidechain. I personally believe that the advantages of rootstock lie in one ️⃣ Security. Rootstock inherits the security of the Bitcoin main chain through 'merge mining'. That is to say, over 80% of Bitcoin's computing power simultaneously protects Rootstock. This is an extremely rare level among all chains. two ️⃣ compatibility. Rootstock is EVM compatible, that is, you can use MetaMask, write Solidity, SushiSwap, and Uniswap, all of which have the same experience. But behind it is not ETH, but rBTC directly linked to Bitcoin. three ️⃣ Low cost+fast speed. Rootstock has recently been upgraded, with a 60% reduction in gas usage and a decrease in block time from 30 seconds to 5 seconds - now it's approaching the L2 experience. As the "infrastructure" for expanding DeFi based on BTC, let's go back to this event In my opinion, the most crucial thing to obtain is the lottery ticket. Almost every interaction is aimed at obtaining the lottery ticket. After each stage is completed, there is an opportunity to participate in the 1x Lil Pudgy NFT lottery and receive additional rewards on DeFi, as well as additional RIF tokens Of course, the more lottery tickets collected, the greater the chance of obtaining Lil Pudgy NFT. The lottery tickets that did not win can also be exchanged for a portion of the RIF token prize pool. Of note is RIF, which is the "Bitcoin scaling token" in the Rootstock ecosystem. It not only participates in governance, but can also be used to incentivize developers, mint stablecoins (such as USDRIF), and register RNS domains similar to ENS. Simply put, it is the 'fuel' that enables Rootstock to operate. The milestone unlocking of the prize pool in this event is also quite interesting. Traditional prize pools usually have a fixed amount of money, which will be evenly distributed in the future. The more people participate in Rootstock's prize pool, the more 50WU can be unlocked, and friends can also be invited to earn extra points. The first stage prize pool consists of over 20WU and additional Boosted APY lottery tickets, including 1x Lil Pudgy NFT and 35000 RIFs for the lottery. The most critical task is to use Stargate to bridge ETH, USDT, or USDC from mainstream chains such as Ethereum, Arbitrarum, BNB, Base, etc. to Rootstock. The operation is actually quite simple. The most important step is to first use Oku to swap ETH across chains to the rbtc of rootstock, ensuring that the rootstock main network has sufficient gas. one ️⃣ Bridge through Stargate, the amount must be above $40 to receive 3 lottery tickets. The specific steps are to open Stargate → select the chain and asset you want to transfer out → select Rootstock (RIF) as the target chain → confirm the linked wallet → wait a few minutes for the funds to arrive I chose to cross chain from BSC's USDC to Rootstock's USDC. E, without any loss in between. It takes about 3-5 minutes to successfully cross chain in terms of time Subsequently, prepare in advance for the subsequent Swap exchange by exchanging USDC.E for RBTC on Oku. two ️⃣ Trading through Oku, Sushi, or WoodSwap, $10-100 is one lottery ticket, $101-500 is three lottery tickets, and $500 or more is five lottery tickets. Because we have already done a swap on the cross chain just now, we suggest that everyone fill up the 5 lottery tickets. After successful cross chain interaction, it is recommended to use sushiswap to exchange rbtc for SolvBTC, and then add liquidity between rbtc and solvbtc through Sushi. Add liquidity of $10-100 for 1 ticket, $101-500 for 3 tickets, and $500 or more for 5 tickets. By using cross chain (3 tickets)+swap (5 tickets)+Add Liquidlty (5 tickets), a single number can receive up to 13 lottery tickets! After completing all interactive tasks, you can participate in feature liking and referral tasks. The specific progress of task completion can be tracked by the Milky Way. I personally believe that Rootstock is doing a 'long-term but very necessary thing': helping Bitcoin truly transition from 'digital gold' to 'usable assets', while establishing a complete developer ecosystem, application ecosystem, and liquidity infrastructure. Golden Sats is a good entry point, and those interested can start with bridging and go through the process to experience it.
