#blacknode There's something new in the Bitcoin ecosystem, blacknode. At around 11 o'clock this morning, under the reminder of the Zishun brothers, I clicked on OPQT, briefly looked at the information and the content of the official @theblacknode, which was further optimized on the basis of brc20 to reduce junk data and redundancy, and make utxo more concise and efficient. It seems that the Bitcoin ecosystem is still innovating around BRC20 and Rune, and I always feel that the Bitcoin ecosystem depends on the progress of the native chain. I'm not optimistic about all the sidechains and layer 2s, or pseudo-mainnets. But there is one thing to note here, such as the Alkanes protocol, which will wrap BTC into fBTC in the AMM developed in the future, which is actually a mainnet asset. Just like ETH, ETH will be encapsulated as a contract asset BETH when doing contract interaction. This is also considered the original chain, because it has not left the mainnet to do development. When my friend told me, the progress of this OPQT was about 45%, and the gas was still at 1 at that time, so I defaulted to the gas fee of 1 when I played, and then 1-3 blocks came to 2, and I thought it was scrapped. Then 2 sets of 40 cards were played with 2 more sets of 3 gases and it was a success. Then a block, 1's gas also passed. But now I can't check whether the wallet has been successfully hit, and I also left a message to the official tweet, because it shows that there are 3 steps, and when the second step is on the chain, it will display mint sucess. I'm not sure if it's a mechanically locked mechanic, or a first-come, first-served mechanic, the previous inscription is first-come, first-served, and the later ones are no longer indexed, which is equivalent to being scrapped. Later, at around 11:30, I saw that Brother Shimizu @chenshuiqing1 also posted this message in his paid ban group. It can only be said that Brother Qing Shui's news about the ecology of flatbread is really early.
