Durable by Math

Secure by Bitcoin

Next-generation Storage & Data Availability Infrastructure

Introduction

Engram Protocol

Built as a Bitcoin Extension Block, anchoring security directly to Bitcoin Proof-of-Work

Capital-efficient, sealing-free storage without centralized custodians

Problem

Light engram

01

Legacy storage models are capital-inefficient

Proof-of-Replication requires sealing, GPUs, high RAM, and high electricity costs, creating entry barriers and poor capital efficiency (CER ~0.2×)

Solution

Light engram

02

Engram – Sealing-free, Capital-efficient Storage

Removes sealing and 3× replication by using Reed–Solomon Erasure Coding (GF2⁸) optimized for HDDs and AVX-512 CPUs.

Algorithmic Durability

14 nines durability, exceeding AWS S3, achieved through mathematical redundancy.

Light engram

Bitcoin-Anchored Security

Security inherited from Bitcoin via Babylon, OP_RETURN checkpoints, and zk-PoSt.

Light engram

Modular Architecture

Separation of security, data availability, and storage enables linear DA scaling and ~80% lower costs.
