We present a state of the art and positioning book, about Digital society
tools, namely; Web3, Bitcoin, Metaverse, AI/ML, accessibility, safeguarding and
telecollaboration. A high level overview of Web3 technologies leads to a
description of blockchain, and the Bitcoin network is specifically selected for
detailed examination. Suitable components of the extended Bitcoin ecosystem are
described in more depth. Other mechanisms for native digital value transfer are
described, with a focus on `money'. Metaverse technology is over-viewed,
primarily from the perspective of Bitcoin and extended reality. Bitcoin is
selected as the best contender for value transfer in metaverses because of it's
free and open source nature, and network effect. Challenges and risks of this
approach are identified. A cloud deployable virtual machine based technology
stack deployment guide with a focus on cybersecurity best practice can be
downloaded from GitHub to experiment with the technologies. This deployable lab
is designed to inform development of secure value transaction, for small and
medium sized companies
