+  32. Network layer properties, implementation using etcd
+authors: [ch1bo]
+tags: [Accepted]
+---
+
+## Status
+
+Accepted
+
+## Context
+
+TODO write context
+
+- First relevant is [ADR 6](/adr/6) which defines the multicast/broadcast primitive
+- Related to [ADR 27](/adr/27)
+  - re-confirm the failure model
+  - superseded decision taken in there 
+- correspondence of reliable broadcast and consensus
+- summarize properties of network layer
+
+## Decision
+
+- We supersede [ADR 17](/adr/17) and [ADR 27](/adr/27) with the current ADR.
+
+TODO write decision
+
+- Define properties of the network layer
+- Precise definition of broadcast to be a reliable broadcast (including Agreement)
+  - https://hydra.family/head-protocol/docs/dev/architecture/networking#interface
+
+TODO write decision (separate ADR?)
+  
+- Decide to use `etcd` as a proxy to achieve reliable broadcast via its raft consensus
+- (or consequence?) Change of `PeerConnected` to `HydraNetworkConnected` semantics
+
+## Consequences
+
+TODO write consequences
+
+- Drop existing implementation using `Reliability` layer (could be revisited, as in theory it would satisfy properties if implemented correctly -> link to Cachin, Uniform reliable broadcast = only deliver when seen by everyone = not what we had implemented)
+- Run time dependency on `etcd`
+- Improved introspectability
+- Crash tolerance of up to `n/2` failing nodes
