PHANTOM:
A Scalable BlockDAG protocol
Yonatan Sompolinsky and Aviv Zohar
School of Engineering and Computer Science,
The Hebrew University of Jerusalem, Israel
{yoni sompo,avivz}@cs.huji.ac.il
Abstract
In 2008 Satoshi Nakamoto invented the basis for what would come to be known as
blockchain technology. The core concept of this system is an open and anonymous network
of nodes, or miners, which together maintain a public ledger of transactions. The ledger takes
the form of a chain of blocks, the blockchain, where each block is a batch of new transactions
collected from users. One primary problem with Satoshi?s blockchain is its highly limited
scalability. The security of Satoshi?s longest chain rule, more generally known as the Bitcoin
protocol, requires that all honest nodes be aware of each other?s blocks in real time. To this
end, the throughput is artificially suppressed so that each block fully propagates before the next
one is created, and that no ?orphan blocks? that fork the chain be created spontaneously.
In this paper we present PHANTOM, a protocol for transaction confirmation that is secure
under any throughput that the network can support. PHANTOM thus does not suffer from
the security-scalability tradeoff which Satoshi?s protocol suffers from. PHANTOM utilizes a
Directed Acyclic Graph of blocks, aka blockDAG, a generalization of Satoshi?s chain which
better suits a setup of fast or large blocks. PHANTOM uses a greedy algorithm on the
blockDAG to distinguish between blocks mined properly by honest nodes and those mined
by non-cooperating nodes that deviated from the DAG mining protocol. Using this distinction,
PHANTOM provides a full order on the blockDAG in a way that is eventually agreed upon
by all honest nodes.

There are several different types of Bitcoin clients. Hybrid server-assisted clients like Electrum get a lot of their network information from centralized servers, but they also check the server's results using blockchain header data. This is perhaps somewhat more secure than either server-assisted clients or header-only clients.

Why is PHANTOM on building on ARK?

ARK Ecosystem is an open-source blockchain project that has created a scalable, interoperable, governed network that in our opinion is the closest to Blockchain-as-a-Service (BaaS) as one system can get. By using the ARK platform their is NO means of any partnership at all. The reasons why we chose to use ARK is because of the results from our case study from online sources that outlines the overall benefits aligned with how our protocol was to be designed. https://medium.com/@phantomdotorg/why-is-phantom-is-building-on-ark-e137452a79f1

PHANTOM Update — Roadmap & Features
On the Phantom website we have updated the roadmap to reflect updates as of today September 10th. Currently we are almost done building the final mainnet desktop wallet that will be ready to use when the PHANTOM main network launches. PHANTOM Desktop Client Beta Version 1.0.1 is now available for Windows, Mac, and Linux operating systems. Users can download this version right from our Github or compile the version themsevlves. This update now reflects our announcement, updates, and relevant news right on the bottom of your client as well as some users whom had issues with the format of the PHANTOM address. The PHANTOM mobile wallet is also nearing the internal beta test phase so we are roughly a few weeks away from releasing the PHANTOM mobile wallets for iOS and Android. The timeline for release will be determined by the App Stores upon submissions and we will keep the community updated. https://medium.com/@phantomdotorg/phantom-update-roadmap-features-797947e95379

Is there a team behind this project or just a bunch of Phantoms?
