Blockchain Technologies and Social Media: A Snapshot


Abstract and Figures

Facebook has proposed to integrate the cryptocurrency 'Libra' into its services, a plan which has been heavily discussed in science, businessand politics. On one receives a tradable-token namend Steem in return for writing popular articles or post comments while at one is rewarded for discovering the next big YouTube video. This shows that Blockchain technologies have an undeniable influence on the development of today's Social Media Networks. On the one hand, we have the technology hype around Blockchain and what kind of new applications are made possible, and on the other hand, the speculation hype around digital tokens (cryptocurrencies) and new forms of investment (ICO, STO), which have in turn resulted in a large number of start-ups in the Social Media and Blockchain sector. Start-ups and products, which quite often disappear from the market in a relatively short time. This paper provides a Snapshot, how Blockchain technologies could influence established Social Networks and gives an overview of known start-ups and their platforms which facilitate Blockchain technologies (like Steemit, Social X, Obsidian, Indorse, Sola,HyperSpace, a.s.o.). Finally, a discussion on how Blockchain technologies can be used beyond speculation is provided.

1. Introduction
In Blockchain jargon, a snapshot is a verified copy of a Blockchain database at a certain point in time (to assist in
synchronizing new nodes1, or to initiate a fork2), a specific timestamp3 (to allow an airdrop4), or the ability to
historically record the price development of traded tokens and cryptocurrencies. For the purpose of this paper,
a snapshot is intended to be the capturing of the current status on the use of Blockchain technologies in Social
Media; four years after Ned Scott and Dan Larimer founded Steemit Inc ( Stemmit is
currently the most popular social network based on token economics and a certain degree of decentralization5.
In 2010 Kwon and Wen describe a Social Network Service (SNS6) as an individual webpage which enables online,
human-relationship building by collection useful information and sharing it with specific or unspecific people,
referring to platforms like Facebook (, Hi5 (, Cyworld
( or MySpace ( While the definition still fits perfectly in
2020, from the top platforms listed 10 years ago, only Facebook remains to be of global relevance according to
today's viewpoint. The ongoing change regarding which platform is considered relevant is similar to the current
situation with new social networks using Blockchain technologies. But the ‘coming and going’ of these platforms
is likely to be even faster than in the early days of traditional social networks.
1 Generalized, a node is a computer that operates a mirrored copy of a Blockchain, synchronized and verified with all other computers on
the network.
2 A fork means if a Blockchain diverges into two potential paths forward.
3 A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time
of day
4 An airdrop is a distribution of a cryptocurrency or token
5 Decentralization is the process by which the activities of an organization are distributed or delegated away from a central, authoritative
location or group
6 Nowadays referred to as social media
Alexander Pfeiffer et al.
2. Related work
Ciriello et. al. (2018) describe a Blockchain Social Network (BSN) as:
[…] a decentralized social media platform that provides a reward mechanism for online user
behavior, such as the creation, curation, and consumption of user-generated online content, here
understood as social networking practices. Through their contributions, users gain reputation and
wealth in form of tokens. […]’ (p2)
This definition is limited to the use of blockchain tokens in the form of reward systems. Apart from using
cryptocurrencies and tradeable to FIAT currency tokens as Incentive (Zhang, 2019; Ciriello et. al., 2019) there
are some fundamental reasons to use Blockchain technology within the context of social networks. The following
potential applications have been identified by the authors:
The embedding of existing or self-initiated (cf. Facebook Libra7) cryptocurrencies as a means of payment
within the Social Media platform. (Claim: Banking the unbanked) (Vivek, 2019)
To establish decentralised name servers (Kalodner et. al, 2015)
The use of Blockchain technologies to protect the ownership and/or author. (Cai et. al., 2018)
Blockchain to prevent spreading rumours (Chen et. al 2018)
Blockchain is used to prove that any media used it is a non-manipulated original (Bhowmik and Feng, 2017)
Protect users from deep-fakes, due to Blockchain implementation. (Hasan and Salah, 2019)
[3,4 and 5 can be summarized as Fake News prevention]
Safeguarding freedom of speech through decentralised server infrastructure (Stjernfelt and Lauritzen, 2020)
Improve and secure Online Advertising (Pärssinen, 2018)
Providing control over the sharing preferences (Murimi, 2019)
Secure and encrypt peer2peer messages (Unger et. al, 2015)
Digital Identity/log in management using self-sovereign identity (SSI) (Sovrin Foundation, 2017)
The authors propose the term Blockchain Embedded Social Networks (BESN) for all social networks and social
messenger services that have integrated blockchain technologies in one or more of the points mentioned above
and use the existing term Blockchain Social Networks (BSN) for platforms, where tokens or cryptocurrencies only
solve the purpose as reward for participation.
3. Blockchain technologies: Background
By definition, a Blockchain is a continuously growing chain of blocks, each of which contains a cryptographic
hash of the previous block, a time-stamp, and its conveyed data (Nofer et. al, 2017). Grech and Camilleri (2017)
describe (positive) effects of Blockchain technologies, like self-sovereignty, trust, transparency, immutability,
disintermediation and collaboration. The concept of Blockchain, as we know it today, derives from Satashi
Nakomoto’s Whitepaper ‘Bitcoin: A Peer-to-Peer Electronic Cash System‘, published in late 2008. Originally
intended to create a non-manipulable account book to represent the possession of digital tokens, which in turn
are traded for money on exchanges or over-the-counter (peer2peer), it is now about the technology behind it
and what applications can possibly be developed using Blockchain technology to secure transactions. The idea
of using the Bitcoin Blockchain for more than ‘proof of payment transactions‘ arose from the fact that you can
attach text messages to a transaction. To create an account book of any imaginable transaction, a fraction of
Bitcoin (so-called Satoshis) was sent to an address and the text to be recorded was attached to it as a text
message and thus stored forever on Blockchain. However, if such information is simply stored as a text message
attached to the same kind of token, this strongly limits its possible applications. And since Bitcoin was not
originally intended for other applications apart from payment, in early 2010, a network in which sub-tokens
(metatokens) can be generated for a specific application was developed. The Blockchain systems NXT
( and Ethereum ( are particularly noteworthy in this
context from a historical as well as current perspective. NXT was the first pure Proof of Stake (PoS) system, a
different approach regarding consensus finding to Proof of Work (PoW), which is by the way considered
environmentally friendly. The Blockchain Social Network Steem uses a Delegated Proof of Stake (DPoS)
7 about Facebook Libra:
Alexander Pfeiffer et al.
consensus mechanism, where users with a high stake have more power over the distribution of the tokens than
users with a smaller stake (Ciriello et. al 2018). Dos Santos (2018) presents a detailed comparison of the two
mining algorithms/consensus finding mechanisms. On the other hand, Ethereum is the second most important
Blockchain system after Bitcoin, especially in terms of market capitalization. Both Blockchain systems mentioned
also have another distinct feature - the possibility to develop smart contracts8. While Ethereum makes this
possible with Solidity, a specially created programming language, NXT uses so-called lightweight smart contracts
in Java. This offers less design freedom, but potentially a higher level of security. Blockchains can be classified
into three major categories (cf. Wan et. al 2019):
1. Private Blockchain: basically, a closed system and exclusively operated within organizations, businesses
or government structures. No information is disclosed to the outside world, except, where appropriate,
evidence of a transaction that has taken place.
2. Consortium Blockchain: serves related parties that have a common goal and organizations can join the
consortium Blockchain on common agreements. Again, no information is disclosed to the outside world,
except, where appropriate, evidence of a transaction that has taken place.
3. Public Blockchain: has no restrictions regarding joining/or leaving Blockchain. All information is public,
although it is possible to store some information in encrypted form.
Researchers like Konashevych (2018) argue that private and permissioned Blockchains are not to be considered
as a Blockchain in its original form. <Author removed for blind review> (2018) created a comparison table to
compare Blockchain systems on the sub-tokens/metatokens, often referred to as utility tokens (all meaning
tokens with a specific purpose, possibly other than use as means of payment), that can be generated. Besides
the already mentioned system NXT and Ethereum, there are (among others) worth mentioning systems,
including Ardor (, Cardano (, Ethereum Classic
(, NEM (, NEO (, Tron ( and
Waves ( Nevertheless, due to the decentralized development, the still short time
(10 years) of the Blockchain idea itself and the interest of industry and society even more recently, there is still
no satisfactory standardized "wording" or "definition" of the different types of tokens (follow discussion e.g.
from Ballandies et. al. 2020) especially an urgently needed differentiation of various different utility tokens
according to their use cases. This classification could ensure that a different legal perspective applies to different
cases. Therefore, <Author removed for blind review> proposed a segmentation regarding Blockchain-based
assets at the <Conference not shown for peer review reasons (2019)>. The proposed category system is a further
iteration for the purpose of this paper:
Cryptocurrencies: Tokens with the purpose to serve as currency supplement and to transfer monetary
values. Traded on dedicated exchanges or over the counter [Like Bitcoin (BTC), Litecoin (LTC)]
Stable-Coin: Tokens with the purpose to serve as currency supplement and to transfer monetary values,
with a nearly fixed conversion rate to a FIAT reserve currency [Like Tether (USDT), USD Coin (USDC), AEUR
Tradeable network maintenance utility tokens: Tokens which serve as a reward to maintain the network
and which are traded on exchanges. May also have aspects of other token categories, e.g. additionally serve
as cryptocurrency [Like Ethereum (ETH), Ethereum Classic (ETC), NXT (NXT), Ardor (Ardr)]
Non free-tradeable network maintenance utility tokens: Not traded on exchanges, but their distribution can
determine the power within a consortium-based (or private) network [tokens that are not traded on
exchanges but distributed from a smart contract or centralised authority, mostly with a fixed number of
issued tokens from the beginning, like a typical PoS approach; this could be also a token that represents a
right to vote for something (and its voting power)]
Tradeable utility tokens: Tokens that have a specific purpose, e.g. to represent a digital or a real good. The
value of this asset is determined by supply and demand on a token trading exchange [like Steem (Steem),
Augur (REP), or ‘historic’ approaches like Amps (AMP), NEXIUM (NXC)]
Fixed-price (including peer2peer price-negotiable) tradeable utility tokens: Tokens that have a specific
purpose, e.g. to represent a digital or a real good. The value of the token is determined by the issuer; a third
party that has a contract with the original publisher that allows them to set the prices, as a result of
8 A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines
of code. The code and the agreements contained therein exist across a distributed, decentralized Blockchain network.
Alexander Pfeiffer et al.
negotiations, or for example at a classic auction (as a restricted bargaining room) [any specific token that
represents e.g. a digital art piece, or a real life item of value (indicating its ownership]
A (tradeable or non-tradable) token representing a share of ownership or a share of contribution to
something, leading e.g. a certain reward [Like KuCoin Shares (KCS), Huobi or Binance Coin (BNC)]
Non-freely tradeable utility tokens: These tokens store data, such as certificates, grades, ownership of a
piece; fine art prints (e.g. limited edition prints, each with a unique number), or a last will; they can be a
unique (singleton) token per record or a message attached to a specific token when sending. A separate
series of tokens is generated for each different use case. Each series has its own asset ID on the respective
Blockchain. (the name of the series does not have to be unique, only the asset ID). This means: The moment
a message is added to one of the tokens (from a series) and this token is sent, the connection of the token
with the message and the rule that the token cannot be forwarded without the knowledge of the original
sender becomes a unique process, which is identified by the unique transaction ID. Messages can be
attached unencrypted or encrypted. This data is usually linked to a person or a property and is not (or only
under specific circumstances) tradable. It is also linked to a specific wallet (e.g. of the recipient). The
Singleton/Unique Token form of this category is similar to the concept of non-fungible tokens (NFTs).
4. Aim of the research
The aims of the research are:
To show which social media networks utilizing Blockchain technologies are known within the community
that has already heard of Blockchain per se and has encountered at least one BSN/BESN.
Which of these applications are already in use (for reading and commenting or as content producer)?
To identify which rewards are important to the people who know or use these networks.
Discover how important privacy, data control and the location of the operator's headquarters are to the
survey participants.
To find out whether the possibility of setting up a fan page or company page is an important function.
To find out the importance of the user experience and other aspects such as reaching friends and relatives.
To get a general opinion on the current situation of Blockchain enabled social networks as well as an outlook
for the near future.
5. Methods
Regarding the data collection a hybrid approach consisting of a qualitative and a quantitative method was used.
After intensive desk-research, and an exploratory phase in which the already available products were tested an
initial open interview was conducted with a social media specialist who has extensive experience with
BSN/BESN. Based on this interview, items for a survey have been defined and consequently an online survey
was made available between November 2019 and the first week of January 2020. A total of 105 respondents
registered their answers and in mid-January, the survey was followed by a moderated focus group, (Mayring,
2010) to discuss the results of the online survey.
5.1 Initial expert interview
The initial interview was conducted with Bernd Pfeiffer, co-founder of Limesoda GmbH (,
one of the leading Austrian Social Media agencies. Between January 2018 and January 2019, Limesoda operated
the site, where they set up various test campaigns. The interview
truly assisted to set up the online questionnaire.
5.2 Online questionnaire
The online survey did not collect demographic data, instead the participants were asked to indicate from which
perspective they fill in the questionnaire. To do so, the participants should at least know one BSN and/or BESN
and the very basic principles of Blockchain technologies. No incentives were given to participate in the survey.
70 people from the private sector took part. 27 also have a professional background in social media and/or
blockchain. Table 1 gives an overview about the classification/perspective of the interviewee

6. Findings
6.1 Which BSN and/or BESN are known to the community
Table 3 shows which BSN/BESN are known to the community. The 105 participants of the survey had the chance
to make multiple entries. The total number of entries per network can be found in the right column. Steemit (by
far) and the two discontinued networks by Synereo (HyperSpace and Wildspark) are the best-known BSN/BESN.
The idea of those networks came up before the 2017 hype peak and that seems to be the reason why they are
well known by the community. The platforms of Synereo are not the only discontinued ones, most of the
platforms mentioned by the interviewees are either discontinued (or at least the underlying token without any
trading volume and delisted from exchanges) or they stopped their efforts before the beta. P2, P3 and P4 explain,
that those BSN (besides Steem) offering their own tradeable tokens have a high chance to be unsuccessful. It
seems that those approaches are only speculative bubbles and they never reach critical mass in trading volume
and user base. P5 commended as an unimposing research prototype, that shows how tokens can be
built into a social network with a purpose beyond speculation. In this sense, the PoS network Ardor might be
worth looking at.

6.2 Participation/content contributions of BSN/BESN
Table 4 shows which BSN/BESN are actually used as recipients (left side) or as content producers (right side).
Again, Steemit is the only relevant platform. HyperSpace and Wildspark have both suddenly been taken offline
during the period of the questionnaire. The sudden discontinuation of these platforms was also commented by
the participants of the online survey who filled in the questionnaire after the discontinuation with very strident
comments in the open field. As with all platforms where you have to invest money in tokens and/or earn the
tokens through hard work, it is understandably awful to suddenly lose this supposed wealth, commented P1 and

6.3 Which aspects are important to act as a reward
Hearts, likes and thumbs up have been rated far above average (which is 3) with (3.94) (see Table 5) . The reward
with nice comments is still slightly above average (3.3), followed by the desire to be rewarded by good content
with vouchers (3.28). Rewards with tokens that can be exchanged for money or with existing cryptocurrencies
are both rated below average. Whereby the possibility of stable coins (2.7) is seen slightly more positive than an
additional gamble with tokens, where the price is determined by supply and demand. P1, P2 and some of the
online survey participants have also pointed out that comments are rewarded with an extra large number of
tokens, so if they get a lot of likes (upvotes), they are obviously just empty positive phrases like 'I like it' or 'more
of it' just to earn tokens. In other words, a culture of simply linking and commenting on things with neutral
phrases has spread. The advantage, however, is that the idea of being rewarded with blockchain based vouchers
was positively highlighted in the comments and also by the focus group participants. As such, it is important to
prevent a black-market and peer2peer trade. P5 particularly emphasizes that this can help to avoid double-
spending, make the forgery of vouchers (nearly) impossible, but also allows for automatic billing and more
complex gamification and loyalty systems.

Getting rewarded with cryptocurrencies or Blockchain-tokens that are convertible to leading
cryptocurrencies or directly to FIAT currencies at a variable price (for postings, likes and comments)
6.4 How important is privacy and ownership to the community?
Privacy settings (3,91) and ownership of the data is (3,9) is far above average (3), asking if those aspects are
important. In the open field several participants mentioned that ‘the Cambridge Analytica’ scandal and recent
hearings from Mark Zuckerberg, CEO of Facebook, helped to better understand privacy on the internet.
Alexander Pfeiffer et al.
Furthermore, the mass media and documentaries on streaming networks are more and more picking on this
topic in their coverage. On the other hand, where the headquarters are located only scored 3 (see Table 6). P2,
P3 and P5, however, have emphasized the importance of precisely this aspect and have shown that those
BSN/BESN which have failed, and which are also accused of fraudulent behaviour by the community were
located in countries where a certain level of basic scepticism could possibly be expressed.

6.5 Importance of certain functionalities and outreach
The user experience (3,92), an already existing large user group (3,79) and the possibility of open communication
using comment fields (3,72) is perceived as important (see Table 7). Quite important is the making of new
friendships (3,5) and easy connection with other social networks (3,45). The fact that family and close friends
receive the content is only seen as relatively important (3,26). P4 supports this fact. It just has to look great on
all the platforms you can use, and you have to understand the functions almost instantly and have fun scrolling
through them. Therefore the user journey is very important.

6.6 Hobby, fan pages and corporate sites
To set up a fan-, project-, hobby- or a company page is regarded by the participants as basically important (see
Table 8). Whereby the possibility to do this without needing a personal profile is preferred (3.61 to 3.56). P5
commented this small difference with a giggle. She hasn't been using her real name in social media for several
years and is extremely sceptical about the distribution of her data. P3 and P4 also think it's good to be able to
be professional on many platforms without also being privately registered. This implies that self-sovereign
identity approaches could also make things a lot easier in the future.

7. Future research
The potential applications of blockchain technologies for social media, as described in the related work section,
must be considered in the future as a crosslinked and not as a separate concept. In this context, different
technologies and especially Blockchain systems must be considered. Based on the aspects described here, the
reasons for the failure of most networks must be discussed further and whether the freely tradable tokens,
where each BSN uses its own token, is to blame for this. Furthermore, the aspect of digital Blockchain-based
vouchers should be considered more closely as it seems that there is still an unused market. Here, the vouchers
would have to be bound to a fixed wallet of the user and only serve the purpose of redeeming them at the
respective company, i.e. a black market must be avoided (and that is exactly where Blockchain is an excellent
Alexander Pfeiffer et al.
8. Conclusion
Providers of BSN/BESN must respond more to the needs of users. After the many failures of recent years, the
fancy marketing vocabulary no longer reaches the people who experienced the market crash in 2018-2020. After
the hype and the many empty promises, it is important to build again solid working platforms with blockchain
functionalities. Blockchain technologies have an incredible potential, not simply to reward users with almost
worthless tokens, but to secure existing platforms against fake news, identity theft, deep-fake videos. Blockchain
can also be used to protect any media from unwanted changes and to map the original source including the
necessary metadata in a tamper-proof way. Finally, further research with larger target groups and changed
methodologies is recommended, as the survey results presented in this paper are based on the self-assessment
of the participants and therefore only cover the target group which, according to the participants themselves,
have already encountered Blockchain technologies in the field of social media.

... The blockchain technology offers to eliminate the need for a central platform altogether, giving individuals the ultimate power of sending and receiving information without oversight or central control [2]. Blockchain technologies also help to protect the ownership and/or author because the data remains untampered by being stored and passed through a blockchain [3] [4]. This allows the authors to get their fair share of profit for their original content without any risk of data tampering. ...

A major issue that writers have to face is the problem of royalty theft. This research is done primarily to overcome this issue and give writers what they deserve. We propose a decentralized book publishing platform that provides authors with a place to publish and sell their work without worrying about royalty theft. The application is built above the Ethereum blockchain, making it secure and completely transparent. During the publishing process, a unique token is created for each new book. After successfully publishing the book, the author can list it for sale. The minted(published) books are treated as Non-Fungible Tokens (NFTs) and can be sold digitally at the owner's will, thereby transferring ownership. The NFT can then be sold time and again, and the author receives a royalty on every sale.

Regarding the scope of the present study, SocialFi tokens can be considered an excellent opportunity for SocialFi platform owners to make and increase their income (Pfeiffer et al. 2020;Shrestha et al. 2020). Moreover, SocialFi tokens handle users' activity very fast. ...

In Web 2.0-based social networks, users suffer from authorities of service providers and politicians, such as revoking users, removing content, and selling users’ sensitive information. The concept of decentralized finance (DeFi) as a blockchain-based technology is one of the most popular achievements of blockchain, involving digital assets, smart contracts, protocols, and applications. In the present study, a new subgroup of DeFi is identified known as social finance (SocialFi). It states that social media components can be presented as blockchain-based tokens and SocialFi can be a solution to the definite problems of centralized social media. Therefore, this study addresses the related technologies of SocialFi (e.g., peer-to-peer networks, Web 3.0, decentralized autonomous organizations, and Metaverse) and describes the challenges and opportunities of the next generation of social media. Some main SocialFi challenges reviewed in this study are scalability, regulation, and fake news detection/prevention. Finally, the future direction of this new field in social and computer sciences is discussed.

Blockchain-based systems have gained immense popularity as enablers of independent asset transfers and smart contract functionality. They have also, since as early as the first Bitcoin blocks, been used for storing arbitrary contents such as texts and images. On-chain data storage functionality is useful for a variety of legitimate use cases. It does, however, also pose a systematic risk. If abused, for example by posting illegal contents on a public blockchain, data storage functionality can lead to legal consequences for operators and users that need to store and distribute the blockchain, thereby threatening the operational availability of entire blockchain ecosystems. In this paper, we develop and apply a cloud-based approach for quickly discovering and classifying content on public blockchains. Our method can be adapted to different blockchain systems and offers insights into content-related usage patterns and potential cases of abuse. We apply our method on the two most prominent public blockchain systems—Bitcoin and Ethereum—and discuss our results. To the best of our knowledge, the presented study is the first to systematically analyze non-financial content stored on the Ethereum blockchain and the first to present a side-by-side comparison between different blockchains in terms of the quality and quantity of stored data.

User privacy has been a topmost priority and one such domain where this is neglected is the area of healthcare. Our solution focuses on the idea of using blockchain to provide a platform for healthcare experts and patients, giving patients full control over the data that will be shared. This paper focuses on identifying current research that has been conducted in this area in the form of a bibliometric analysis. A bibliometric study on a research area involves a detailed analysis of citations and papers across a domain of study. The purpose of this study is a statistical analysis of publications which is so complex that it is close to impossible to understand trends merely based on knowledge and experience. There are specific tools required to recognize these trends based on the bibliometric data. This paper will give an outlook on the areas of blockchain that were explored by various papers, the criteria and pattern followed by the combination of papers, and a cumulative statistical analysis of the papers that were fetched for the purpose of our study from the Scopus database. The most popular visualization software tool VOSviewer was taken into use.
This chapter delves into the potential of decentralized social networks to address the growing concerns surrounding privacy, censorship, and user control on centralized social platforms. Offering an alternative to traditional social media, decentralized social networks foster trust and transparency in online interactions by leveraging distributed ledger technologies like blockchain where data is stored across multiple nodes controlled by the users themselves. Decentralized networks utilize such systems to offer the means for privacy and communication without censorship or interference, empowering users with greater control over their personal data. Combining the exploration of decentralized social networks' fundamental features, analysis of advantages and challenges, and examination of real-world initiatives, this research aims to contribute to the understanding of this Web 3 phenomenon and its potential to reshape the social media landscape in a decentralized, democratic, and user-centric way.

In addition to the general intentional scattering of fake news and its conscious or unconscious sharing on social media networks, the problem of checking the origin of source material from the perspective of the consumer is evident. This is especially the case if the original material was not created and registered with great care by established and trustworthy media companies. In the fast-paced world of real-time reporting, even professional media houses have to rely on cell phone videos or other user-created material. Furthermore, it is also possible that source material only appears to have been produced by an established media company, but instead journalists who work with this material fall victim to well-crafted forgery. The aim of this research study is to discuss Blockchain technologies and their adoption to store a verification hash of source material, the proof of authorship and sources used in a forgery-proof way. Furthermore, the authors investigate whether journalists and media producers see a need in this technology. The discussion centres around the consumers' perception of such possible verification as an improvement and something they recognize as a "trust amplifier" if embedded in the newspaper, journal, blog, social media platform, or messenger tool of their choice. Finally, the sociological and ethical dimensions are briefly discussed-whether and how verified material can ultimately be fake news once again, and if the perception of what one believes, does not depend at the end on the recipient's basic attitude and perception. This work in progress paper describes the current status of the research work and outlines the envisaged further procedure.

Social Networks are already multiple service platforms and, badly that despite many sectors of activity, they are a lion competitor because they have what it takes a lot of time and money to get any sector: they have the public-potential consumer of whatever-with whom they have been building trust for years. Social networks have become an excellent customer service tool in many industries, and banking is no exemption. The implementation of artificial intelligence in different industries has brought profound changes in production processes. However, it is the banking industry that has benefited most from this type of technology. Concentrating on client services and accepting the idiosyncrasies of people they serve, small financial institutions, banks, and financial unions can teach big institutions what it means to be close to the clients. AI, Blockchain, virtual reality and augmented reality are striving to attract more customers towards social networks banking.

With the rise of AI and deep learning techniques, fake digital contents have proliferated in recent years. Fake footage, images, audios, and videos (known as deepfakes) can be a scary and dangerous phenomenon, and can have the potential of altering the truth and eroding trust by giving false reality. A Proof of Authenticity (PoA) of digital media is critical to help eradicate the epidemic of forged content. Current solutions lack the ability to provide history tracking and provenance of digital media. In this paper, we provide a solution and a general framework using Ethereum smart contracts to trace and track the provenance and history of digital content to its original source-even if the digital content is copied multiple times. The smart contract utilizes hashes of the InterPlanetary File System (IPFS) used to store digital content and its metadata. Our solution focuses on video content, but the solution framework provided in this paper is generic enough and can be applied to any other form of digital content. Our solution relies on the principle that if the content can be credibly traced to a trusted or reputable source, the content can then be real and authentic. The full code of the smart contract has been made publicly available at Github.

The 200-billion-dollar per annum online advertising ecosystem has become infested with thousands of intermediaries exploiting user data and advertising budgets. All key stakeholders in the value-chain are infected: advertisers with fraud, publishers with their diminishing share of advertising budgets, and users with their right to privacy. Blockchain presents a possible solution to addressing the critical issues in the online advertising supply chain. The question remains whether blockchain scalability, energy-efficiency, and token volatility issues can be solved in the coming years to the extent that online advertising could widely leverage trustlessness and the benefits gained from blockchain technology. This paper aims to review the current progress and to open a discussion to address the issues. We present new requirements for blockchain-based online advertising solutions. We have also analyzed the available solutions against the requirements and recommend directions for future research and solution development. Evidence from our research points out that blockchain is not yet ready to be widely implemented in online advertising. More research is needed, and new proof-of-concepts need to be developed before blockchain technology can be considered a trusted alternative for the current online advertising marketplace based on Open Real-Time Bidding (Open RTB).

Motivated by recent revelations of widespread state surveillance of personal communication, many solutions now claim to offer secure and private messaging. This includes both a large number of new projects and many widely adopted tools that have added security features. The intense pressure in the past two years to deliver solutions quickly has resulted in varying threat models, incomplete objectives, dubious security claims, and a lack of broad perspective on the existing cryptographic literature on secure communication. In this paper, we evaluate and systematize current secure messaging solutions and propose an evaluation framework for their security, usability, and ease-of-adoption properties. We consider solutions from academia, but also identify innovative and promising approaches used 'in-the-wild' that are not considered by the academic literature. We identify three key challenges and map the design landscape for each: trust establishment, conversation security, and transport privacy. Trust establishment approaches offering strong security and privacy features perform poorly from a usability and adoption perspective, whereas some hybrid approaches that have not been well studied in the academic literature might provide better trade-offs in practice. In contrast, once trust is established, conversation security can be achieved without any user involvement in most two-party conversations, though conversations between larger groups still lack a good solution. Finally, transport privacy appears to be the most difficult problem to solve without paying significant performance penalties.
Social network services are emerging as a promising IT-based business, with some services already being provided commercially such as Facebook, Cyworld and Xiaonei. However, it is not yet clear which potential audience groups will be key social network service participants. Moreover, the process showing how an individual actually decides to start using a social network service may be somewhat different from current web-based community services. Hence, the aims of this paper are twofold. First, we empirically examine how individual characteristics affect actual user acceptance of social network services. To examine these individual characteristics, we apply a Technology Acceptance Model (TAM) to construct an amended model that focuses on three individual differences: social identity, altruism and telepresence, and one perceived construct: the perceived encouragement, imported from psychology-based research. Next, we examine if the users’ perception to see a target social network service as human relationship-oriented service or as a task-oriented service could be a moderator between perceived constructs and actual use. As a result, we discover that the perceived encouragement and perceived orientation are significant constructs that affect actual use of social network services.
