-### Payloads
-
-Payloads are implemented using [protocol buffers v3](https://developers.google.com/protocol-buffers/).
-
-**CAS service**:
-
-```protobuf
-syntax = "proto3";
-
-package vac.cas;
-
-service CAS {
-  rpc Add(Content) returns (Address) {}
-  rpc Get(Address) returns (Content) {}
-}
-
-message Address {
-  bytes id = 1;
-}
-
-message Content {
-  bytes data = 1;
-}
-```
-
-<!-- XXX/TODO: Can we get rid of the id/data complication and just use bytes? -->
-
-**NS service**:
-
-```protobuf
-syntax = "proto3";
-
-package vac.cas;
-
-service NS {
-  rpc Update(NameUpdate) returns (Response) {}
-  rpc Fetch(Query) returns (Content) {}
-}
-
-message NameUpdate {
-  string name = 1;
-  bytes content = 2;
-}
-
-message Query {
-  string name = 1;
-}
-
-message Content {
-  bytes data = 1;
-}
-
-message Response {
-  bytes data = 1;
-}
-```
-
-<!-- XXX: Response and data type a bit weird, Ok/Err enum? -->
-<!-- TODO: Do we want NameInit here? -->
-
-**Remote log:**
-
-```protobuf
-syntax = "proto3";
-
-package vac.cas;
-
-message RemoteLog {
-  repeated Pair pair = 1;
-  bytes tail = 2;
-
-  message Pair {
-    bytes remoteHash = 1;
-    bytes localHash = 2;
-    bytes data = 3;
-  }
-}
-```
-
-<!-- TODO: Better name for Pair, Mapping? -->
-
-<!-- TODO: Extend pair with (optional) data -->
