We are quickly approaching a milestone where another digit will be added to the block number. Assuming nothing goes wrong, block #100,000,000 is expected to be produced in the next 48 hours as of writing this. Most likely the block would already been produced by the time you are reading this.

The last time an event like this occurred was on [8 Mar 2017, 17:34:24 UTC](https://hivehub.dev/b/10000000). A brief period of network congestion will be expected as everyone will try to get their transactions included in exactly block 100M. The next time another digit will be added after block 100M (which will be block 1B) will be in another 85.6 years, provided that the year 2106 timestamp serialization problem will be fixed by then.

With the courtesy of VSC, my ticket for HiveFest 10 is secured. With less than 2 weeks to go, preparations for the event are at full gear.

Looking forward to see all of you in person again.

#### HAF db
All HAF apps belong to individual schemas in a single PostgreSQL database along with data such as app state providers in the `hafd` schema. This section shows the sizes of each schema in the database using the following query:

```sql
SELECT schemaname,
    pg_size_pretty(SUM(pg_total_relation_size(relid))) AS total_size,
    pg_size_pretty(SUM(pg_table_size(relid))) AS table_size,
    pg_size_pretty(SUM(pg_indexes_size(relid))) AS indexes_size
FROM pg_catalog.pg_statio_user_tables
GROUP BY schemaname;
```
