0x is an open-source, decentralized exchange infrastructure that enables the exchange of tokenized assets on multiple blockchains.

The 0x protocol is, at its core, a set of secure smart contracts that facilitate the peer-to-peer exchange of Ethereum-based assets. The protocol serves as an open standard and common building block for any developer needing exchange functionality. 

In addition to the externally audited smart contracts, 0x also offers developer tools tailored to the ecosystem and open-access to a pool of shared liquidity.

Developers can integrate with 0x at the smart contract or application layer.

Serverless Hosting Incentivised Peer-To-Peer Storage And Content Distribution.

Swarm is a distributed storage platform and content distribution service, a native base layer service of the ethereum web3 stack. The primary objective of Swarm is to provide a decentralized and redundant store for dapp code and data as well as block chain and state data. Swarm is also set out to provide various base layer services for web3, including node-to-node messaging, media streaming, decentralised database services and scalable state-channel infrastructure for decentralised service economies.

In this document, we outline the design for a Lightning Service Authentication Token (LSAT) for future services created by Lightning Labs. This specification is open source, with contributions accepted at our LSAT specification repository.  LSATs are a new standard protocol for authentication and paid APIs developed by Lightning Labs. LSATs can serve both as authentication, as well as a payment mechanism (one can view it as a ticket) for paid APIs. In order to obtain a token, we require the user to pay us over Lightning in order to obtain a pre-image, which itself is a cryptographic component of the final LSAT token.

The implementation of the authentication token is chosen to be macaroons, as they allow us to package attributes and capabilities along with the token. This system allows us to automate pricing on the fly and allows for a number of novel constructs such as automated tier upgrades. In another light, this can be viewed as a global HTTP 402 reverse proxy at the load balancing level for all our services.

Chainlink is blockchain middleware that allows smart contracts to access key off-chain resources like data feeds, various web APIs, and traditional bank account payments. By providing smart contracts secure access to these key resources, ChainLink allows them to mimic real world agreements that require external proof of performance and need to make payment in widely available payment methods e.g. bank payments.

The Chainlink Network is a decentralized network of ChainLink Nodes, which are all selling usage of specific data feeds, APIs and various off-chain payment capabilities directly to a smart contract. Any data, payments, e-signature, or other API provider, as well as individual developers, can easily join the network by connecting an API they're familiar with. Once the API they'd like to offer to smart contracts is connected to a ChainLink, they become a ChainLink Node Operator, responsible for keeping that API connected to the ChainLink Network and being compensated in LINK for their successful fulfillment of on-chain requests.

DAOSTACK POWERS DECENTRALIZED COMPANIES, FUNDS AND MARKETS TO MAKE FAST AND INNOVATIVE DECISIONS AT SCALE.

DAOstack runs on GEN. GEN is the native token of the DAOstack platform. Basic operations across the DAOstack ecosystem – such as promoting proposals – will require the spending or holding of GEN. GEN will be distributed to contributors of value through the DAOstack framework itself, incentivizing development, promotion and adoption

Cardano is developing a smart contract platform which seeks to deliver more advanced features than any protocol previously developed.
