I build TSDB (10,000,000 samples per seconds and average query time is almost 200ms) over clickhouse which support multi insert protocol (influxdb line protocol|prometheus remote write|opentsdb json format) and opentsdb query protocol and incomplete PromQL. Clickhouse is good but something you need to tunning. using memory table to speedup insert,high performance zookeeper to improve replicated table, data shard via timeseries id (distributed_group_by_no_merge=1) to reduce bootstrap node load
The contract address is shown in the Mist/MetaMask prompt. Checking that when you first deposit would be sufficient. (Sure, it's probably true that many users would fail to check that, but I think it counts for something that there is an obvious way that anyone could verify what they were committing their funds to.)

I just forgot I was using CDNs from google since I wrote the site 6 years ago...
