Canada is legalizing marijuana and leaving it up to provincial governments to regulate its sale and distribution.

IBM helped build a different kind of blockchain
The idea of a blockchain originated with Bitcoin. The Bitcoin blockchain is the public, shared ledger that keeps track of payments in the Bitcoin network. The volatility of Bitcoin's virtual currency has hampered its mainstream adoption as a payment network. But companies quickly realized that the core concept of the blockchain could be repurposed for other applications.
