+## Abstract
+
+The Codex slot builder module partitions dataset blocks into slots,
+builds individual Merkle trees for each slot enabling cell-level proof generation, and
+constructs a root verification tree over all slot roots.
+
+## Background
+
+The Codex protocol places dataset blocks provided to the network by requester into slots.
+Slots are then stored by nodes in the marketplace.
+
+## Specification
+
+The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”,
+“SHOULD NOT”, “RECOMMENDED”, “NOT RECOMMENDED”, “MAY”, and
+“OPTIONAL” in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
+
+Build block-level digest trees from raw data
+A storage request requires the dataset to 
+
+Construct slot trees from block digests
+Create verification trees from slot roots
+Manage empty blocks and padding
+Store cryptographic proofs in the block store
