performance

We identified that read-only host cache could only be enabled on disks <4096GB.

For searchers with 4TB disks, we now deploy disks of size 4095GB to take advantage of the read-only host cache.

We expect things to be a lot faster!

wss & https

Titan has deployed new encrypted channels with TLS authentication. We will be sunsetting the unencrypted channels once all searchers have migrated.

They will be served from the same IP 52.207.17.217 , at the new ports 42203 and 1338.

state diffs: wss://fbtee.titanbuilder.xyz:42203
bundle rpc: <https://fbtee.titanbuilder.xyz:1338>

Breaking Changes

• Please submit to the DNS above for TLS authentication
• Please run the following command to cache DNS resolution (remember: DNS is not available during production mode!)

echo "52.207.17.217 fbtee.titanbuilder.xyz" >> /etc/hosts

sync-proxy

We are moving away from lighthouse on the host to a sync-proxy setup, where engine events are streamed from Flashbots’ CL cluster.

Sync-proxy is run on the searcher side to dedup CL engine events.
