[The frontier](https://blockspace.wiki/glossary/the-frontier/) is the block up to which a [BTI](https://blockspace.wiki/glossary/bti/) figure is true: the height every registered protocol has been searched to. BTI keeps a cursor for each stage, the census, the claims and the books, so each board on block.space says [as of block H](https://blockspace.wiki/glossary/as-of-block-h/). A number without its height is not shown.
