What is a Blockchain?


“A block chain or blockchain is a distributed database that maintains a continuously-growing list of transaction records hardened against tampering and revision. It consists of data structure blocks—which hold exclusively data in initial blockchain implementations, and both data and programs in some of the more recent implementations—with each block holding batches of individual transactions and the results of any blockchain executables.Each block contains a timestamp and information linking it to a previous block. The block chain is seen as the main technical innovation of bitcoin, where it serves as the public ledger of all bitcoin transactions.Bitcoin is peer-to-peer, every user is allowed to connect to the network, send new transactions to it, verify transactions, and create new blocks, which is why it is called permissionless. This original design has been the inspiration for other cryptocurrencies and distributed databases.” --Wikipedia

(1) How might this technology be relevant to academic and research libraries?

  • Building a blockchain to track scholarly publication, including discovery registration. - bryan.alexander bryan.alexander Oct 17, 2016
  • Blockchain technology could be an important instrument to secure the integrity of scholarly communication. Publications and research data. - Laurents.Sesink Laurents.Sesink Nov 10, 2016 Interesting idea. This or something related could potentially upend scholarly practices. - kristi-thompson kristi-thompson Nov 12, 2016 Yes, will hopefully see some experiments in this area in the future - erik.stattin erik.stattin Nov 13, 2016

(2) What themes are missing from the above description that you think are important?

  • Ethereum as an example of blockchain tech as platform. - bryan.alexander bryan.alexander Oct 17, 2016
  • The risks with fragmentation of blockchain tech - erik.stattin erik.stattin Nov 13, 2016
  • add your response here

(3) What do you see as the potential impact of this technology on academic and research libraries?

  • This technology might support "badging" for co-curricular skills acquired through training provided by academic libraries (for example digital literacy information literacy, and research skills) in ways that could authenticate the content of personal skills portfolios. - g.payne g.payne Oct 20, 2016
  • Publications and research data are floating over the internet. Once they are out of their Trusted Digital Repositories there is at the moment not a good way to secure the integrity of the information. Blockchain technology could play a significant role to discover what kind of transactions have been committed. - Laurents.Sesink Laurents.Sesink Nov 10, 2016
  • Blockchain is the basis of Internet of Things, it maybe used in intelligent library in the future.
