It\u2019s been a busy week for cryptocurrency developer Unwriter \u2013 hopefully he decided to take a well-deserved break this weekend. After bringing to the Bitcoin SV (BSV) community Genesis, Babel and Chronos, he has now introduced his fourth project of the new year, Meta. In his Medium post, Unwriter described the latest creation as a \u201cBitDB for Bitcoin Block Metadata.\u201d https:\/\/www.youtube.com\/watch?vgBb9FSxfyVs Meta was created to allow for the implementation of queries of block metadata. The developer adds that it \u201ccompletely deviates away\u201d from the object schema for BitDB transactions, but that it still allows Bitqueries as do all other BitDBs. Unwriter explains, \u201cMeta is the first BitDB to crawl all the way from the Genesis block, which means you can query the entirety of the blockchain\u2019s metadata set, instead of from a certain block height (Currently the Genesis and Babel nodes start crawling from height 525470, and the Chronos node doesn\u2019t even have this concept, it has a 24 hour sliding window policy of ephemerality)\u201d Meta is able to search all the way back from the first Genesis Block. It doesn\u2019t include any transactions \u2013 only block metadata \u2013 and is a database of all block metadata. To query the transactions, users can use Genesis, Babel or Chronos. The latest node was created to be lean. It only stores the block metadata and the entire database is only approximately 1.2GB, making it possible to be included in the memory of any computer. Meta adds a couple new attributes, as did Chronos, including \u201cchainworkdecimal\u201d and \u201ctimeago.\u201d The latter is calculated based on the \u201ctime\u201d attribute and the former is calculated at runtime from the \u201cchainwork\u201d attribute. Chainwork stores its data in hexadecimal format, and chainworkdecimal converts its output to decimal format. Unwriter explains, \u201cMeta is a new type of BitDB that gives you access to Bitcoin\u2019s block metadata. For the first time, the schema is completely different from other BitDB nodes because Meta crawls the block metadata instead of transactions. However you can still \u2018magically\u2019 use the same Bitquery used in all other BitDBs (Genesis, Babel, Chronos) to interact with Meta.\u201d Meta can be used in conjunction with the other available BitDBs in order to build powerful applications. It is one of a growing number of tools that make the BSV blockchain more useful in a variety of functions and is helping the network receive the notoriety it deserves.
