Decentralized content curation is the process through which uploaded posts are ranked and filtered based exclusively on users' feedback. Platforms such as the blockchain-based Steemit employ this type of curation while providing monetary incentives to promote the visibility of high quality posts according to the perception of the participants. Despite the wide adoption of the platform very little is known regarding its performance and resilience characteristics. In this work, we provide a…

A Puff of Steem: Security Analysis of Decentralized Content Curation

This work provides a formal model for decentralized content curation that identifies salient complexity and game-theoretic measures of performance and resilience to selfish participants and validates the theoretical results with system simulations in various scenarios.

Decentralized Content Vetting in Social Network with Blockchain

This chapter proposes a blockchain‐based decentralized content vetting for social network, uses Bitcoin as the underlying blockchain model, and develops a unidirectional channel model to execute the vetting procedure.

The role of cryptocurrency in the dynamics of blockchain-based social networks: The case of Steemit

An analytical framework to assess the impact of the cryptocurrencies linked to a BOSN platform on the evolution of its social network and on the behavior of their users, in terms of production of content and/or its promotion through a voting and rewarding system is proposed.

SteemOps: Extracting and Analyzing Key Operations in Steemit Blockchain-based Social Media Platform

SteemOps is a new dataset that organizes more than 900 million operations from Steemit into three sub-datasets namely (i) social-network operation dataset (SOD), (ii) witness-election operation datasets (WOD) and (iii) value-transfer operation dataset, designed to facilitate future research aimed at providing deeper insights on emerging blockchain-based social media platforms.

A Graph-Based Socioeconomic Analysis of Steemit

The properties of the Steemit follower–following graph are evaluated to understand how the social and the economic aspects of BOSMs intertwine and influence each other and shows that users can get rich without much involvement in the platform, using external mechanisms.

Social and rewarding microscopical dynamics in blockchain-based online social networks

This study focuses on a few temporal characteristics, by analyzing the dynamics of the link creation process and the claiming of rewards in the BOSN Steemit, and model blockchain data as a temporal directed network from which the time series characterizing link creation and reward claims are extracted.

Rumour prevention in social networks with layer 2 blockchains

In this paper, a decentralised method to prevent social bots is developed and it is proved that the proposed solution can significantly reduce the number of users who are share rumour.

When Blockchain meets Online Social Networks

Privacy Preserving Opinion Aggregation

This work explores opinion aggregation in a decentralised, iterative setting by proposing a novel protocol in which randomly-chosen participants take turns to act in an incentive-driven manner as decryption authorities, which provides public verifiability, robust vote privacy and liveness guarantees, while striving to minimise the resources each participant needs to contribute.

Recent Advances of Blockchain and its Applications

This paper investigates recent advances of both blockchain technology and its most active research topics in real-world applications, including blockchain enabled IoT, edge computing, federated learning and several emerging applications, where detailed specific research topics are discussed in each.

Canal: scaling social network-based Sybil tolerance schemes

Canal is presented, a system that uses landmark routing-based techniques to efficiently approximate credit payments over large networks and provides up to a three-order-of-magnitude speedup while maintaining safety and accuracy, even when applied to social networks with millions of nodes and hundreds of millions of edges.

Steering user behavior with badges

A formal model for reasoning about user behavior in the presence of badges is introduced and several robust design principles emerge from the framework that could potentially aid in the design of incentives for a broad range of sites.

Tezos : A Self-Amending Crypto-Ledger Position Paper

This paper aims to remedy the potential for atrophied evolution in the crypto-currency space by presenting Tezos, a generic and self-amending crypto-ledger that can instantiate any blockchain based protocol.

Can social news websites pay for content and curation? The SteemIt cryptocurrency model

SteemIt is a Reddit-like social news site that pays members for posting and curating content. It uses micropayments backed by a tradeable currency, exploiting the Bitcoin cryptocurrency generation

Measurement and analysis of an online content voting network: a case study of Digg

This paper analyzes Digg, a popular online social news aggregator and rating website, and studies structural properties of Digg social network, revealing some strikingly distinct properties such as low link symmetry and the power-law distribution of node outdegree with truncated tails.

Sybil-Resilient Online Content Voting

SumUp is presented, a Sybilresilient vote aggregation system that leverages the trust network among users to defend against Sybil attacks and uses the technique of adaptive vote flow aggregation to limit the number of bogus votes cast by adversaries to no more than theNumber of attack edges in the Trust network.

A Theoretical Analysis of Crowdsourced Content Curation
