Operating an Anchor Node & Auto-Mirroring

Anchor Nodes provide guaranteed content durability across Membuss networks.

1. Automated Mirroring Protocol​

When anchor_mode: true is configured:

  1. The node monitors announced entry-node MIDs on Mem-DHT and PEX.
  2. It fetches and mirrors announced content trees using worker concurrency pools.
  3. Content remains available network-wide even if original uploader nodes disconnect.

2. Bloom Filter Delta Sync & Bounded Storage​

  • Bloom Delta Sync: Exchanges inventory Bloom filter snapshots to prevent redundant data fetches (cutting sync traffic by $> 95%$).
  • Bounded Storage & LRU Eviction: Maintains a max_storage quota (e.g. 100GB). Unpinned auto-mirrored content is evicted using LRU ordering when storage limits are reached, while operator-sealed content remains immune from eviction.
