  Blockchain, Smart Contracts and Distributed Ledger Technology (DLT) are being
touted to revolutionise digital services - through decentralisation.
Cryptocurrencies, self-sovereign identities, decentralised certificate
registries, and transparent voting systems are but a few applications which
promise to empower endusers and provide assurances that neither data nor the
associated computational logic have been tampered with.
  Decentralisation, disintermediation, transparency, verifiability,
auditability, openness, inclusion, tamper-proof, immutability are just some of
the buzz words that continue to be swung around in the promotion of the
benefits brought about by Blockchain-based systems to the users. The rhetoric
used creates parallels between the features brought about through blockchains
and values that many try to uphold, for example honesty, openness,
transparency, teamwork and unchanging truth.
  In this paper a number of blockchain applications aimed at supporting
initiatives for common good are highlighted. This is followed by a discussion
on technology de/centralisation and a thought experiment used to raise
questions regarding the use of decentralised technology in terms of social
implications.
