Quant Overledger V0.1
1. Introduction
The invention of Bitcoin [1] achieved a new technological milestone: the blockchain. Despite the
underlying technology in blockchain is not new, the innovation results from a combination of
existing technologies that have been integrated in an original way to create blockchains. The
components (i.e., Merkel Tree, concatenated hashes, public-key encryption) were already
established technologies well before the Bitcoin paper by Nakamoto in 2009 [2].
At the moment of writing, we may argue that, according to the Technology Life Cycle
theory, we are at the beginning of the so-called phase of “fermentation” which is characterised by
technological uncertainty due to the evolution of blockchain into alternative technical paths. The
industry promotes different model designs favouring functional and performance aspects over
others to meet specific business goals. Currently, there are more than a thousand digital currencies
(for clarity the phrase digital currency and...

such as technologies forking, becoming insecure or being abandoned altogether. In the
development of blockchain applications, the choice of the underlying blockchain technology
cannot be easily undone and migrations are not always possible because the transactions have
scope only on their blockchain address space. For example, Blockstack [10], an open-source
project to create, manage and use decentralized apps on blockchain, decided to move from
Namecoin to Bitcoin because the first technology was considered less secure. The migration of
applications is a problem that can soon also regards those ones running on Ethereum [17]. This is
an endless problem whose solution cannot just be designing better and smarter blockchains
because front-end technologies of today will become obsolete in a few years due to planned and
unplanned obsolescence. To solve these issues, Overledger presents the following solutions:

Introduction of new scripting languages or updating existing ones; ...

performance of different blockchains that are running the same application. All these aspects
together will help boost blockchain technology, its applications and the opportunities to exploit
the technology widely.
The next subsection will analyse existing solutions to the problem of single-ledger
dependency. We will also in this paper introduce mathematical models with the order theory for
blockchains whilst considering other technical aspects of the underlying blockchain technologies
required to deliver such a solution.
1.2 State of the Art
This section provides an overview of those projects that, although pursuing different final goals,
propose alternative solutions to the problem of the lack of blockchain communicability and
interoperability. This is a rather new and evolving stream of research; therefore we focused only
in the main projects and compare them with Overledger:

Interledger wants to enable payments between any users holding assets in separate ledgers without
the need to trust a third party.
AION-1
. Aion seeks to solve scalability, privacy, and communication issues among digital
ledgers. It aims to provide decentralized accountability among blockchain networks. AION
claims to introduce a next-generation blockchain that enables intercommunicating blockchains.
The first generation presents the decentralized ledger technology, cryptographically secured like
Bitcoin and the second one enhances smart contract and distributed apps like Ethereum.
According to the AION classification, the third generation adds the ability of communication and
value exchange among ledgers.
Sidechain.
Sidechain and Interledger protocols are two projects that aim to promote
communication among blockchains and allow asset transfers. While Sidechain builds ad-hoc
external chains that can interact automatically just with a specific blockchain (not fu...

function of arbitrary strings long enough to host a hash is classified as writable. In this case, users
can use optional fields of a regular transaction to add the hash of arbitrary messages. The ledgers
that do not offer a write function of arbitrary strings but do offer a read operation are labelled
readable.
Until now, the proposed solutions for blockchain interoperability depend on the specific
goals for which the projects were originated.
Interledger
. The protocol for Interledger payments can connect any two ledgers that have a
connector with at least one node in each of the ledgers. It is possible to connect two ledgers, let’s
say A and C, which are not directly joined by a connector if there is a path between ledgers that
starts from A and ends in B.
Virtualchain
. Virtualchain allows running state machine on the top of a specific blockchain. If
the underlying blockchain becomes obsolete or no longer suitable, Virtualchain offers the ability
to m...

simultaneously. Overledger can read information like transactions, scripts or contracts and map
them in the “over layer” only if that information is compliant with the selected business logic. In
this way, Overledger can connect all blockchains that allow the ability to add an arbitrary hash of
a message to host. In most cases, the projects that encourage connectivity among blockchains
create a network of ledgers where the asset or the information needs to be routed from the source
to the destination across different hops (when it is applicable). We do not propose a network
approach; we introduce a multi-layer approach. We move the information in the layers above
creating by common interface among ledgers.
In table 1 we summarise the level of interoperability by using the following notation:

1-C-1: Two connected blockchains per time with a connector;

N-C-N: Many connected blockchains per time with connectors;

1–1: Two connected blockch...
