Blockchain Technologies Feature Analysis

Hi all,

This is a follow up from the Blockchain CG face-to-face meeting at W3C
TPAC. At the meeting, I noted that we had performed some security,
privacy, and performance analysis of various Blockchain technologies. We
have just gotten clearance from the Department of Homeland Security to
release this analysis (attached).

We analyzed Bitcoin, Ethereum, Stellar, IPFS, Blockstack, and Hashgraph.
The most interesting portions of the report are the "Security Principles
Summary Chart" and the "Performance Principles Summary Chart".

This analysis helped us decompose the blockchain technologies analyzed
into modular components, such as consensus algorithms, data structures,
APIs, and other "standardizable bits". Those bits helped us design the
Flex Ledger spec (which we'll be updating later this month):

We may want to expand the analysis tables in this group and use them to
break down other blockchain technologies and the strategies that they
use to achieve security and performance principles like integrity,
confidentiality, information availability, etc.
