Title:  Blockchain: History, Challenges and Opportunities


Abstract:  The history of blockchains go back further than most people realize. The actual word "blockchaining" already appeared in print in 1978, and it related precisely to what we think of as the basic structure of blockchains today. Some of the underlying technologies go back even further. In this talk, I will tell this history. We find blockchains in quite familiar places. I will also discuss what innovations sparked the modern huge interest in blockchains. Where are blockchains really necessary? When are they just expensive extravaganzas? What are the real opportunities, and why have so many espoused just a few years ago not materialized?

Topic: On PeerCoin Proof of Stake for Blockchain Consensus


Abstract: Proof of Stake (PoS) has been talked about extensively as an alternative way of reaching consensus in blockchain systems. However, there are few publications on how PoS can be used to create new blocks in detail. The undisputed lead proponent for PoS is Ethereum. However, virtually all discussions regarding PoS for Ethereum are centered on selecting a block using PoS after one or more candidate blocks have already been somehow created. PeerCoin was the first blockchain system that incorporated PoS in block creation. Unfortunately, there is no known documentation on how PoS works in PeerCoin. In this paper, we fill this gap by presenting a detailed explanation of the PeerCoin PoS algorithm based on PeerCoin source code. We also dispel the misconception that PeerCoin PoS is based on Proof of Work (PoW) and hence would consume a lot of energy just like proof of work (PoW). In fact, it resembles PoW only on surface and differs from PoW substantially in terms of how to meet the difficulty target.

Topic: The Effect of Blockchain-Based Donation System on Donation Behavior


Abstract: Donation Phobia has been spreading out over the years due to financial scandals of donation corruption in a few nonprofit organizations in Korea. This study attempts to  figure out whether the blockchain-based donation system (BDS) can be of help in solving this problem by increasing the trustworthiness of a nonprofit organization. This study tested the effect of BDS on trustworthiness of a nonprofit organization, and consequently, the effect of trustworthiness on satisfaction, donation intention and donation behavior by comparing a regular donation website with the BDS. All the three unique features of blockchain-based donation system – transparency, immutability, and efficiency – affect trustworthiness of the BDS site and the path from trustworthiness to donation behavior is more influential at the BDS site than that at the regular donation website. Moreover, the causal relationships between the three unique features of BDS and information offered by the website are significant at the BDS site but not at the regular online website. This study implies that, as a mean of recovery of trustworthiness of a nonprofit organization, the blockchain-based donation system can play a critical role.
