A Groundbreaking Smart Contract Storage Layer
with EGGS

The Future of Decentralized Applications

Smart Contract Storage Layer with EGGS​


The web3 ecosystem is continuously evolving, and the need for efficient and scalable solutions has become increasingly crucial. Xandeum, a groundbreaking L1 blockchain, is at the forefront of this innovation, offering a revolutionary smart contract storage layer called EGGS (External Global Grouped Storage). In this blog post, we’ll discuss the impact of Xandeum  on the web3 landscape and explore how it’s paving the way for next-generation decentralized applications.

Xandeum: A Game-Changer in the Blockchain Space

Xandeum solves a pressing problem for humanity, creating a platform that gives smart contracts the missing storage layer. On existing L1 (as well as L2) chains, it is economically not feasible to store gigabytes or even terabytes of data. The reason for that is simple: Existing smart contract platforms are not built to have a storage layer. The result is some L1’s can scale very well on compute, but horribly on storage. This means that Web3, up until today, is mostly an unfulfilled marketing promise, as Elon Musk tweeted in December 2021. Xandeum sets itself apart from other L1 blockchains by offering a unique combination of advanced technology including a delgated storage layer, and developer-friendly tools. By using the Move programming language, Xandeum provides an optimal developer experience, making it easier for developers to create and deploy decentralized applications. The platform’s innovative approach to storage through EGGS positions it as a game-changer in the world of smart contract storage layers.

EGGS: The Smart Contract Storage Layer Solution

EGGS is designed to improve the scalability and efficiency of decentralized applications. By providing a secure, off-chain storage system, EGGS reduces the load on the main blockchain, allowing for faster transaction times and improved overall performance. The actual storage data will not reside within each and every validator (that’s what prevents economic feasibility with today’s platforms), but storage is delegated to millions of storage provider nodes all over the world. Each storage-enabled web3 dApp, dubbed sedApp, can use the delegates storage layer, easily accessible using the Move language, to store data redundantly and with blockchain features such as true decentralized control, censorship resistance and being tamper-proof. As the demand for storage in the web3 ecosystem grows, it will be a critical factor in determining the success of decentralized applications. In addition to improving scalability and efficiency, EGGS also provides a range of other benefits. For example, it provides a higher level of security than traditional storage solutions, since it is fully decentralized and transparent. This means that there is no single point of failure or vulnerability that can be exploited by attackers.

Note that existing storage solutions in the blockchain space won’t do the trick to enable real web3 apps. Filecoin, Siacoin and others are primarily designed to provide “stand alone” blockchain-based storage, not as a storage layer for smart contracts. Storing on IPFS does not give the full set of blockchain features, since IPFS isn’t a blockchain. For example, there is not even consensus on existence on IPFS, making it a very poor choice for most, if not all, web3 sedApps. NFT compression (a misnomer since it doesn’t compress) is a specialized solution for NFTs and does not enable general sedApps. Existing storage layers for smart contracts, such as ShadowDrive, don’t offer decentralized control, and no censorship-resistance.

The Benefits of Xandeum’s Smart Contract Storage Layer Solution

By choosing Xandeum, web3 startups can harness the power of EGGS to create scalable and efficient decentralized applications. Some key benefits include:

  • Critical Enabler for Web3: Without a scalable, blockchain-based storage layer, smart contract will simply not be able to enable real web3 seDApps.
  • Enhanced Scalability: EGGS enables decentralized applications to handle increased workloads and adapt to the growing demands of the web3 ecosystem.
  • Improved Efficiency: By offloading storage to EGGS, developers can achieve faster transaction times and better overall performance for their applications.
  • Developer-friendly: Xandeum’s use of the Move language and EGGS storage layer simplifies the development process and empowers developers to create innovative web3 solutions.


Xandeum, with its revolutionary smart contract storage layer, EGGS, is poised to transform the world of decentralized applications. By offering a scalable, efficient, and developer-friendly platform, Xandeum is the ideal choice for web3 startups seeking to build on a robust L1 blockchain. Don’t miss the opportunity to join the Xandeum ecosystem and experience the future of smart contract storage layer technology with EGGS.
