 ## Store Adapters for P2P Integration
 
 The store package provides adapter implementations that wrap the ev-node store to satisfy the `header.Store[H]` interface from the `go-header` library. This enables the ev-node store to be used directly by go-header's P2P infrastructure, eliminating data duplication.
-
-### Background
-
-Previously, ev-node maintained redundant storage:
-
-1. **ev-node store** - Primary store for headers, data, state, and metadata
-2. **go-header stores** - Separate stores for P2P sync (headerSync and dataSync prefixes)
-
-This resulted in the same headers and data being stored multiple times.
-
-### Solution: Store Adapters
-
-Two adapter types wrap the ev-node store:
-
-- **`HeaderStoreAdapter`** - Implements `header.Store[*types.SignedHeader]`
-- **`DataStoreAdapter`** - Implements `header.Store[*types.Data]`
-
-These adapters:
-
-- Read from the single ev-node store
-- Write to the ev-node store when receiving data via P2P
-- Provide the interface required by go-header's exchange server, syncer, and subscriber
-
-### Usage
-
-```go
-// Create the ev-node store
-evStore := store.New(kvStore)
-
-// Create adapters for P2P infrastructure
-headerAdapter := store.NewHeaderStoreAdapter(evStore)
-dataAdapter := store.NewDataStoreAdapter(evStore)
-
-// Use with go-header P2P components
-exchangeServer, _ := goheaderp2p.NewExchangeServer(host, headerAdapter, opts...)
-```
-
-### Benefits
-
-1. **Single source of truth** - All block data lives in one place
-2. **Reduced disk usage** - No duplicate storage of headers and data
-3. **Simplified rollback** - Rolling back the ev-node store automatically affects P2P sync
-4. **Atomic operations** - Block storage and state updates remain atomic
