+- Added `GetBigLedgerPeerSnapshot` block query. 
+  This query retrieves a snapshot of big ledger peers derived from
+  stake pools available at the current slot in the ledger state. This
+  snapshot is intended to be serialised and made available to the 
+  cardano-node via configuration so that it may sync up safely to end
+  up on the correct chain; big ledger peers are those peers with significant
+  relative stake compared to other relays and hence are treated as
+  trustworthy peers by the Genesis algorithm.
