Performance is one of the major challenges facing blockchain technology today. The blockchain
which uses Bitcoin designed to handle seven transactions per second, and Ethereum only
can handle a few more. In December 2017, a simple CryptoKitties application can
slowing down Ethereum and increasing transaction costs dramatically.
Current consumer applications should be able to handle tens of millions of active users every day. Other than that,
some applications will only become meaningful when a critical mass is reached. The platform itself should
able to handle a large number of concurrent users.
A good user experience demands a reliable response with only a second delay
sub. longer delays to thwart users and create applications built on blockchain
less competitive with nonblockchain alternatives available.

PROBLEMS WITH TODAY BLOCKCHAINS
Blockchain technology is still in its infancy. There are many problems preventing the developer
and business from creating broad, decentralized blockchain applications
Current blockchain applications are built for little technological whizzes that know how
use it, not mainstream consumers. Almost all blockchain applications require
users to either run blockchain nodes or install "light nodes." The learning curve and
the effort involved has delayed the adoption between the general public.
For example, while Ethereum-based CryptoKitties games are probably the most user-
friendly decentralized applications ever built, still requires the user to install
light wallet Metamask2 browser extension. Users also need to know how to buy ether
secure and use it with Metamask.
People have high hopes for-the blockchain of news media, evangelists, and journalists
painting a bright future for decentralized applications for the public, especially at a price
the higher the cryptocurrencies. In fact, however, blockchain technology is still deep
growth period. Most blockchain services lack feature rich and do not have
mechanisms to encourage people to contribute to the heap of features.

THE ARCBLOCK PLATFORM
ArcBlock solves this problem through a revolutionary new design. Unlike its predecessor,
ArcBlock is a service platform, rather than a standalone software package or API set. ArcBlock
is a comprehensive solution that incorporates blockchain technology with Cloud Computing. Blocklets are nothing more than blockchains access. It connects to existing data sources, and performs
both in chains and off-chain computing.
Its unique design aims to provide high performance, user-friendly, cost-efficient, and
protocolagnostic platform. We believe that ArcBlock is a major technological advancement
will usher in  generation of blockchain applications.

DESIGN PRINCIPLES
ArcBlock design is based on the following core principles:
- The user experience first.
- performance thing.
- This system will be built on open standards.
- This system will build an Incentive-driven economy.


ADVANTAGES ARCBLOCK'S
In addition to solving the general problems described above, build and deploy applications
Decentralized blockchain with ArcBlock has a significant advantage over special frameworks
vendors available on the market today.


ARCHITECTURE SYSTEMS
The ArcBlock Platform introduces a suite of revolutionary technologies designed for applications
blockchain by making them easy for the average consumer to use.


OPEN ACCESS CHAIN ​​PROTOCOL
Our open source protocol provides an abstract layer to access the blockchains
underlies. Similar to ODBC or JDBC interface for a set of databases, our Open Chain
Access Protocol allows your application to work on different blockchains. No
it is necessary to change the business logic or work with some chain technology.
Chain adapters can be built by the community and driven by an incentive mechanism. It will
allows ArcBlock to support multiple blockchain protocols and keep improving.

DECENTRALIZATION PUB / SUB GATEWAY
A distributed messaging system supports pub / sub and acts as a gateway API for
Blocklets.
ArcBlock gateway uses decentralized design and secure communication channels. application
You will run on both web browsers and mobile apps, giving reactive users,
real-time experience. gateway supports a variety of network protocols by default, including
WebSocket, DDP, HTTPS, and MQTT. advanced developers can extend the gateway with
New network protocols fit their needs.

MARKET AND ECONOMIC TOKEN
ArcBlock comes with a fully customized token economy manager for built applications
on the platform. Applications can even build unique utility tokens that inherit all the features
ArcBlock.
The ArcBlock Marketplace is an original app built on top of ArcBlock to allow
community contribute and reusable exchange components (eg Chain Adapters, Blocklets, or
even apps).
The diagram below shows a high-level view of the architecture platform. detailed description of
some of the core components appear in the next section.
