26. Blockchain risks?
ISSUE
26
Regular global technical meetings (i.e. NY Agreement)
SegWit / Offchain Transactions
Cybersecurity Hacks
Mt Gox, Ethereum DAO, Bitfinex
Silk Road, drug dealers,
terrorists, criminals
Scalability
Block size, Consensus method
Mining Centralization
51% Attack
RESPONSE
Temporary; mining is collusive; attack unsustainable, cannot
steal coins, confirm transactions or change protocols
Building resilient system constantly under open attack 24/7
(remember early Internet DNS attacks)
Blockchains are a universal technology available to all; non-
criminal activity predominates
Technology Risk
Perception Risk
Regulatory Risk, Economic Risk
Government regulation,
bans; Exchange rules
Governments modernizing economic infrastructure with
blockchains too; licensing, open dialogue
