+### TieredBlockstore
+
+A tiered blockstore wraps one or more blockstores and will query each in parallel to retrieve a block - the operation will succeed if any wrapped store has the block.
+
+Writes are invoked on all wrapped blockstores.
+
+```js
+import { TieredBlockstore } from 'blockstore-core/tiered'
+
+const store = new TieredBlockstore([
