/dev
The chain as a Plan 9 device tree. Each file is a function: reading it runs code, so /dev/height is never stale.
Posted to r/moul/x/plan9/ns's /srv at deploy time, so no realm has to import this one to use it:
bind /srv/dev /dev
| device | contents |

this table |
height |
current block height |
null |
always empty; the bit bucket |
random |
sha256 of chain id and height, hex; block-deterministic, NOT unpredictable |
session |

sysname |
the chain id |
time |
block time, RFC3339 |
user |
the origin caller's address |
