AudioCoin (ADC) - A Digital Currency for the Music Industry
The music industry has evolved to a point where streaming services (excepting Japan) account for the majority of revenues. A large percentage of this revenue filters through the 3 major labels and because of the low (or free Ad revenue supported) model, the returns to artists are miniscule. Combine this with a fairly lousy user experience and there becomes a compulsive argument for a new music consumption model that generates viable revenues for labels/artists, greater levels of engagement and added value for users/consumers.
What the music industry needs right now is innovation and a fresh start. It needs a Bob Dylan strapping on an Electric Guitar, It needs a Woodstock, it needs a Punk Rock style ground zero revolution.
In developing AudioCoin we looked at the problems facing the Music Industry and by thinking laterally to include the financial eco-system surrounding the business, we were able to come up with a model that is both truly revolutionary and perhaps more importantly, ethical and fair.
Our remit was to empower and engage music lovers all over the world and to break down any barriers that prevent music consumption even in third world countries. It needed to unshackle the need for young music lovers to borrow their parents credit cards to use iTunes or Spotify. Most of all it needed to create a global and ethical music ecosystem that was robust, exciting and open to everyone.
AudioCoin builds on the Proof of Stake protocol to provide a new way to consume music. It breaks down the barriers of traditional e-commerce systems and provides a super cool way for music fans and artists to engage in viral marketing. The main gain is that artists (producers) and music fans (consumers) are rewarded tangibly and thereby rendering the current streaming model both archaic and redundant.
So what is AudioCoin and how does it work?
AudioCoin (ADC) - Real World Application from Launch
Crypto-currencies have been plagued by two opposing forces. The profligation of speculative new coins and (obtusely) a lack of real world applications other than profiteering on virtual exchanges. When the first idea of AudioCoin was mooted, our main goal was to put the application specific features at the forefront of our thinking.
As a solution for a particular vertical (The Music Industry) the coin has been developed so that the core software and applications can be ported to any other online music related platform. Our IP consists of the way we have applied open source software into a bespoke solution that can be plugged in to any other site.
By partnering with Blockpool and their BLOCKTOOLS suite, we can deliver both backend functionality along with creative marketing applications using AudioCoin.
Case Study: Bjork (One Little Indian Records)
We engaged with the One Little Indian label for the release of Bjork’s Utopia album in Q4 2017.
AudioCoin was integrated into the system as follows:
As well as enabling the purchase of the album via AudioCoin using a Magento plugin, all customers who bought the album at the Bjork store were provided with an online (or virtual) mobile compatible wallet. The wallets. These customers (whether purchasing using regular old school cash or digital currency were awarded coins for buying items at the store and further coins for engaging with and sharing the content via their chosen social media channels. The artist was then able to unlock limited edition content to these users.
AudioCoin can be used in multiple ways to create a value model for all stakeholders and bring unprecedented opportunities for creative activations.
Music Industry Adoption
AudioCoin is gaining traction through adoption and the application of creative initiatives by various significant music industry stakeholders. We have working models for festivals and other live events using Geo-location technology. This technology was piloted at SXSW in Austin Texas in 2018.
In addition we’ve delivered activations for Miloco Studios (A global network of music recording studios and equipment retailers), Salute Music (A Facebook-based music project involving voting and crypto rewards), Aurovine (a web-based music streaming and distribution platform).
We have engaged in constructive discussions with all the major music industry stakeholders and have Master Service Agreements pending with a number of high profile organisations.
AudioCoin is fully decentralised and any iterations are driven by the community. The latest version of the client wallet is 3.0.2.
In Q3 of 2018 the short, medium and long term strategy is being driven by enthusiasts along with music industry professionals who realise the value of stable music industry digital currency that is now approaching 2 million blocks.
The strategy is currently in process with a number of music industry related organisations (including media, live events, brands, technology providers and brand protection companies).

Much of our development could not have been accomplished without the open source work already completed by Sunny King and Scott Nadal in developing the Peercoin crypto-currency and of course Satoshi Nakamoto’s Bitcoin. Excerpts from the Peercoin whitepaper by kind permission of Sunny King.
We have subscribed to the premise of a proof of stake design for the coin. Under this hybrid design proof-of-work mainly provides initial minting and is largely non-essential in the long run. Approximately 20% of the coin supply will be available for distribution and mining during the proof-of-work stage. The security level of the network is not dependent on energy consumption in the long term thus providing an energy-efficient and more cost-competitive peer-to-peer crypto-currency.
Proof-of-stake is based on coin age and generated by each node via a hashing scheme bearing similarity to Bitcoin’s but over limited search space. Block chain history and transaction settlement are further protected by a centrally broadcasted checkpoint mechanism.
Since the creation of Bitcoin (Nakamoto 2008), proof-of-work has been the predominant design of peer-to-peer crypto currency. The concept of proof-of-work has been the backbone of minting and security model of Nakamoto’s design. In October 2011 the Peercoin developers realized that, the concept of coin age could facilitate an alternative design (known as proof-of-stake) to Bitcoin’s proof-of-work system.
The concept of coin age was known to Nakamoto at least as early as 2010 and used in Bitcoin to help prioritize transactions, for example, although it didn’t play much of an critical role in Bitcoin’s security model. Coin age is simply defined as currency amount times holding period. In a simple to understand example, if Bob received 10 coins from Alice and held it for 90 days, we say that Bob has accumulated 900 coin-days of coin age. Additionally, when Bob spent the 10 coins he received from Alice, we say the coin age Bob accumulated with these 10 coins had been consumed (or destroyed).
In order to facilitate the computation of coin age, the Peercoin developers introduced a timestamp field into each transaction. Block timestamp and transaction time stamp related protocols are strengthened to secure the computation of coin age.
Proof-of-work helped to give birth to Nakamoto’s major breakthrough, however the nature of proof-of-work means that the crypto-currency is dependent on energy consumption, thus introducing significant cost overhead in the operation of such networks, which is borne by the users via a combination of inflation and transaction fees.
A solution had to be found that would offset the need for energy consumption in order to have a decentralized crypto-currency. The Peercoin developers moved forward with a proof-of-stake model that was discussed among Bitcoin circles as early as 2011. Roughly speaking, proof-of-stake means a form of proof of ownership of the currency.
Coin age consumed by a transaction can be considered a form of proof-of-stake. The Peercoin developers realized that proof-of-stake could indeed replace most proof-of-work’s functions with careful redesign of Bitcoin’s minting and security model.
This is mainly because, similar to proof-of-work, proof-of-stake cannot be easily forged. Of course, this is one of the critical requirements of monetary systems - the difficulty of counterfeiting.
Block Generation under Proof-of-Stake
In the hybrid design, blocks are separated into two different types, proof-of-work blocks and proof-of-stake blocks. The proof-of-stake in the new type of blocks is a special transaction called coinstake (named after Bitcoin’s special transaction coinbase). In the coinstake transaction the block owner pays himself thereby consuming his coin age.
The first input of coinstake is called kernel and is required to meet certain hash target protocol, thus making the generation of proof-of-stake blocks a stochastic process similar to proof-of-work blocks. However an important difference is that the hashing operation is done over a limited search space (more specifically one hash per unspent wallet-output per second) instead of an unlimited search space as in proof-of-work, thus no significant consumption of energy is involved. The hash target that stake kernel must meet is a target per unit coin age (coin-day) consumed in the kernel (in contrast to Bitcoin’s proof-of-work target which is a fixed
target value applying to every node). Thus the more coin age consumed in the kernel, the easier meeting the hash target protocol.
Minting based on Proof-of-Stake
A new minting process is introduced for proof-of stake blocks in addition to Bitcoin’s proof-of-work minting. Proof-of-stake block mints coins based on the consumed coin age in the coinstake transaction.
Main Chain Protocol
The protocol for determining which competing block chain wins as main chain has been switched over to use consumed coin age. Here every transaction in a block contributes its consumed coin age to the score of the block. The block chain with highest total consumed coin age is chosen as main chain. This is in contrast to the use of proof-of-work in Bitcoin’s main chain protocol, whereas the total work of the block chain is used to determine main chain. This design alleviates some of the concerns of Bitcoin’s 51% assumption, where the system is only considered secure when good nodes control at least 51% of network mining power. First the cost of controlling significant stake might be higher than the cost of acquiring significant mining power, thus raising the cost of attack for such powerful entities. Also attacker’s coin age is consumed during the attack, which may render it block contains a duplicate pair as another previously received block, we ignore such duplicate-stake block until a successor block is received as an orphan block.
When the proof-of-work mint rate approaches zero, there is less and less incentive to mint proof-of-work blocks. Under this long term scenario energy consumption in the network may drop to very low levels as disinterested miners stop mining proof-of-workblocks. The Bitcoin network faces such risk unless transaction volume/fee rises to high enough levels to sustain the energy consumption. Under the hybrid design even if energy consumption approaches zero the network is still protected by proof-of-stake. We call a crypto-currency long-term energy-efficient if energy consumption on proof-of-work is allowed to approach zero.
Proof-of-stake designs have become a more competitive form of peer-to-peer crypto-currency to proof-of-work designs due to the elimination of dependency on energy consumption, thereby achieving lower inflation/lower transaction fees at comparable network security levels.
We reserve the right to make modifications to this code for the good of the community and coin. ADC is not designed for speculation, rather a real world application to solve problems and create a level playing field for music industry stakeholders (artists, labels, fans, services). We encourage a collaborative community to help us make the coin succeed with fair rewards for both Development and Coin adoption.
