Blockstack

Full stack blockchain development ecosystem providing native identity, blockchain, token creation and more as API's for developers, as well as a browser for end-users to interact with dApps on the Blockstack platform.  Their mission seems to be to cater to developers that want to create decentralized applications and they provide a full technology stack to developers to build dApps on the Blockstack platform, and for users to access dApps on the Blockstack platform.

IOTA looks to be the next generation blockchain, using a new architecture called a DAG (Directed Acyclic Graph) that lends itself towards being suitable for Internet of Things applications such as data transfer and maching-to-machine micro-payments.

IOTA aims to solve three problems with the current cryptocurrency ecosystem, transaction fees, scalibility, and offline transactions. Blog post covering this here: https://medium.com/@cryptojudgement/iota-promise-of-a-bright-crypto-future-6b7517349e32

Sept 7, 2017: Cryptographic Vulnerabilities in IOTA

https://lisk.io/

Lisk is a 3rd generation blockchain learning from Bitcoin and Ethereum and taking different approaches, of note, the idea of integrated federated sidechains have particular potential. It is similar to Ethereum in that it allows for execution of code for smart-contracts and dApps to be written on the platform, Lisk uses Javascript for programming dApps, where Ethereum primarily is using Solidity.  Lisk takes a full stack approach to blockchain application development offering native sidechains, and SDK's for front-end/UI and back-end/Logic development. Lisk also talks about Identity, Decentralized Infrastructure, Smart-Contracts and Oracles as examples of side-chain applications, it will be interesting to see how these types of services will operate between blockchain platforms.  In particular, at the time of this writing, it seems that Lisk provides native identity/user-login as a core feature, does this mean that in order to be a user on the Lisk network you must use your Lisk identity verification or will other schemes such as Civic provide seamless access to Lisk blockchain dApps?

I have not found a whitepaper, but there is this very informative blog post: What is Lisk?

This note from the blog post sheds light on the Lisk approach:

There are ongoing discussions about public, private, and consortium blockchains. With Lisk you can build whatever you want and need. However, in order to attract startups and developers we are putting our main focus on public consortium blockchains. That means federated blockchains which are secured by delegates chosen from a public marketplace which are being paid for generating blocks, either by the blockchain application owner or its users. Continue reading in order to learn more about the Lisk delegate marketplace.

Lisk uses Delegated Proof of Stake for it's consensus algorithm, for sidechains this creates a marketplace for securing your applications ledger, from the blog post:

The Lisk delegate marketplace is a way to connect blockchain application developers and sidechain delegates. This is necessary, because every sidechain is an independent blockchain which needs its own set of nodes to secure it. If blockchain application developers don’t use our default consensus algorithm (e.g. PoS or PoW) they will have to take care of the sidechain miners/forgers themselves, which might be a better option for some use-cases. However, if the blockchain application developer is using our default consensus algorithm (DPoS) he will be able to rent delegates from the delegate marketplace for a recurring fee.

Omisego is clearly aiming for mass adoption with a tag line "Unbank the Banked with Ethereum". Their home page describes their mission pretty well...

OmiseGO is a public Ethereum-based financial technology for use in mainstream digital wallets, that enables real-time, peer-to-peer value exchange and payment services agnostically across jurisdictions and organizational silos, and across both fiat money and decentralized currencies. Designed to enable financial inclusion and disrupt existing institutions, access will be made available to everyone via the OmiseGO network and digital wallet framework, starting in Q4 2017.

and...

The OmiseGO network is intrinsically agnostic between fiat and decentralized money: as far as adoption and usage go, the system is constructed so that the best currencies will win.

These statements can describe the aspirations of many other blockchain projects.  What separates this project from others is the experience of the team, highlights include the Bitcoin Lightning Network project, and Ethereum.

Their thinking is also very clear in terms of what matters in a payment, wallets... and simply transferring value between two wallets for each transaction:

The OmiseGO White-label Wallet SDK will allow a diversity of payment solutions to be easily deployed on the robust OmiseGO network. Digital wallet providers have the flexibility to enhance, add, and customize payment solutions for various industries and vertical markets. All transactions across digital wallet providers will be conducted on the OmiseGO network, and decentralized currencies can be traded freely alongside fiat money by all network users.

EOS

Quote from the project white paper: https://github.com/EOSIO/Documentation/blob/master/TechnicalWhitePaper.md

The EOS.IO software introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved by creating an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across hundreds of CPU cores or clusters. The resulting technology is a blockchain architecture that scales to millions of transactions per second, eliminates user fees, and allows for quick and easy deployment of decentralized applications.
