Innovation overload in the modularity space! It’s hard to keep track of all the awesome projects launching.

That’s why I’m curating them all at Modular (modular-sigma.vercel.app)

Here’s a sneak peek of some projects:

DA (Data Availability) Space:

Data availability refers to guarantees that the data needed to verify a block in the blockchain is actually available to all network participants. This concept is fundamental to the proper functioning of blockchains, as it allows for full validation of the blockchain’s history and current state by any participant, thereby maintaining the decentralized and trustless nature of the network. Without guaranteed data availability, participants could not independently verify the legitimacy of transactions and blocks, which could lead to issues like fraud or censorship within the network.

EigenDA (by EigenLabs): First mover! This Ethereum-based service guarantees data availability using EigenLayer’s restaking system.
EIP-4844 blobs : A new Ethereum feature allowing temporary storage of data chunks (blobs) on beacon nodes.
Celestia 🪶: Makes light nodes lighter! Utilizes data availability sampling (DAS) so nodes don’t download entire blocks, and namespaced Merkle trees (NMTs) for targeted data retrieval by execution and settlement layers.
Avail DA ✅: Enables developers to verify data availability themselves using validity proofs, eliminating trust reliance on Avail.
NEAR | Data Availability : NEAR Protocol’s solution for scalable Web3, specifically designed to address challenges faced by Ethereum rollups.

Shared Sequencers: Powering the Future of Rollups ⚡️

The goal of shared sequencing is to bring stronger network security and better network decentralization through shared usage of sequencers as roll-ups currently maintain their own sets of sequencers (usually only one sequencer) and aren’t censorship-resistant and interoperable with other rollups. (Similar to problems plaguing layer-1 networks)

Espresso Systems ☕️: Their Espresso Sequencer focuses on credible neutrality, smooth interoperability, and aligning rollup economics with the underlying Layer 1 blockchain.
Astria : A permissionless network where anyone can join the sequencer pool, ensuring a truly decentralized system.
Radius ️: Combats MEV (malicious actors manipulating transaction order) using advanced cryptography, keeping things fair and efficient.

Rollup-as-a-Service

Developers building dApps have several options for deployment, including existing blockchains, Layer 2 solutions (L2), custom appchains, and rollups. Rollups can offer a sweet spot between customization, performance, and development effort, particularly with the simplified setup offered by Rollups-as-a-Service (RaaS) providers. These providers offer tools and services, ranging from rollup management to no-code deployment, enabling easy creation and maintenance of custom rollups.

Conduit ️: Offers a robust suite of tools for deploying both optimistic and zk-rollups, catering to a wider range of developer needs.
AltLayer : Focuses on user experience with their innovative “Flash” technology, enabling instant finality for rollup transactions.
Dymension : Acts as a settlement layer and bridging hub, connecting your rollup to various blockchains for seamless asset transfers.
Cartesi : Provides a unique “Linux on Blockchain” environment, allowing developers to leverage familiar tools like Linux and tools like the Ethereum Virtual Machine (EVM) for rollup development.
Caldera : Specializes in launching optimistic rollups, known for their fast transaction speeds and familiar programming environment.
