X KOL Brother Leek (X: @cryptoleek) published a brief introduction to the basic knowledge of the BRC 20 protocol, including its source, composition and derivative protocols, etc. Odaily compiled it as follows:
1/Today we talk about the BRC 20 agreement.
2/ BRC 20 is completely developed based on the #Ordinals protocol. It is no exaggeration to say that without Ordinals, there would be no BRC 20. BRC 20 by anonymous master@domodataInvented, wrote a set of protocols, and then refined them by various communities and Bitcoin teams. in@unisat_walletand@okx web3It has played a very important role in promoting the entire BRC 20.
3/ So what is BRC 20? In fact, it consists of two parts: one is the inscription engraving, and the other is the offline indexer. Let’s look at them one by one.
4/ Inscription casting: As mentioned before, inscription can cast any form of file, including JSON file. The BRC 20 protocol stipulates three types of minting inscriptions. The first is called the deploy inscription, which stipulates the symbol of the token, the maximum supply, the minting limit, etc.
5/ The second one is called the mint inscription, which stipulates how many tokens you are going to mint.
6/ The last one is called the transfer inscription, which stipulates the transfer situation between brc 20, the number of transfers, etc. More details. Reference documents:https://layer1.gitbook.io/layer1-foundation/protocols/brc-20/documentation
7/ The second part is the offline INDEXER. The function of the Indexer is to find all the BRC 20 minting on the Bitcoin chain, and to index out the number of coins each person holds based on their deploy, mint, and transfer conditions. Of course, there are many indexing rules. I will list a few as examples. Please refer to the documentation for details.https://layer1.gitbook.io/layer1-foundation/protocols/brc-20/indexing
8/ The currently famous open source indexers are as follows:

9/ ALPHA is currently being promoted by someone in the community#BRC 420 is an interesting experiment, which recursively defines more complex asset formats, such as game items, animations and effects, or game modules in the Metaverse. These formats will be fully open source, allowing anyone to create their own Metaverse Inscriptions.
