Each block contains a certain amount of data and is connected to other blocks through hash links. This structure grants blockchain high security and transparency. As new data blocks are continuously added to the chain, the entire database grows, forming an ongoing, distributed ledger."}]}],"pr":"03de8868915ac6f8c7f9212334b852ac1efb4c0e85e88990d13d647f3bb33f8c"}
