#blacknode New developments in the Bitcoin ecosystem, blacknode. Around 11 AM today, after a reminder from Brother Zishun, I tried some OPQT, briefly looked at the information and the official Twitter content of @theblacknode. It is based on brc20 with further optimization to reduce junk data and redundancy, making utxo more concise and efficient. It seems the Bitcoin ecosystem is still innovating around brc20 and rune. I always feel that the Bitcoin ecosystem should focus on the progress of the native chain. I am not optimistic about all side chains and layer twos, or pseudo-mainnets. But there is something to note here, such as the Alkanes protocol. In the subsequent development of AMM, BTC will be encapsulated into fBTC, which is actually a mainnet asset. Just like ETH, when interacting with contracts, ETH is encapsulated into contract asset BETH. This is also considered a native chain because it does not leave the mainnet for development. When my friend told me about OPQT, the progress was around 45%, and the gas was still at 1, so I assumed a gas fee of 1 when I tried it. Subsequently, 1-3 blocks reached 2, and I thought it was wasted. Then I used 2 addresses with a gas of 3 and successfully hit 2 groups totaling 40 pieces. Subsequently, a block with a gas of 1 also passed. However, now I cannot check if the wallet successfully hit it. I also left a message on the official Twitter because it shows 3 steps, and during the second step on-chain, it shows mint success. I am not sure if its mechanism is a locking mechanism or a first-come-first-served mechanism. Previously, the inscriptions were first-come-first-served, and the later ones were not indexed, equivalent to being wasted. Later, around 11:30, I saw Brother Qingshui @chenshuiqing1 also posted this message in his paid mute group. I can only say Brother Qingshui is really early with news about the big pie ecosystem.
