+## Abstract
+
+This specification describes the erasue coding technique used in the Codex protocol.
+Erasue coding is used by the Codex client to encode datasets being presented to the [marketplace]().
+
+## Background
+
+Codex uses storage proofs to determine whether a storage provider is storing a certain dataset.
+Storage providers agree to store dataset for a period of time and
+store an encoded dataset provded by the requester.
+Using erasure coding,
+client nodes will be able to restore datasets thatare abandoned by storage providers.
+Also validator nodes are able to detect whether data is missing within a slot.
+
+## Semantics
+
+The keywords “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”,
+“SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and
+“OPTIONAL” in this document are to be interpreted as described in [2119](https://www.ietf.org/rfc/rfc2119.txt).
+
+The Codex client performerasure coding locally before provding dataset to the marketplace.
+
+### Flow
+
+Before data is provided to storage providers on the marketplace,
+clients must do the following:
+
+1.
