-- block_tx_idx 指交易id；当该行数据为BlockHash的时候指的是最近的block number  
+- block_tx_idx 指该条目的idx，在block相关的条目，表示该block在chunk的idx。在交易相关的条目，等于block_idx * 2^32 + tx_idx，tx_idx表示表示该tx在block的idx。当tag=BlockHash, 表示允许获取该条目的max_block_idx.
 
 ## 多功能列 Versatile columns
 为了减少列的使用,缩减电路规模,设计了多功能的列。在不同的行数据类别下,这些列存放不同的数据。目前设计有4个多功能列,代码里呈现为:
