Blockchains have the potential to support businesses and processes without boundaries. Before blockchains, systems relied on intermediaries and duplicate data flows to manage and reconcile information between parties. Now with blockchain technology, these flows can be achieved directly in a secure and non-repudiable way. Blockchains can connect parties more efficiently and effectively than ever before, reducing the latency and inconsistency inherent in many multi-party processes. Furthermore, the secure nature of blockchain transactions and the immutability of the data allows for processes to be automated to a far greater degree due to the level of trust we can place in that data.Blockchains are a natural fit in a world of connected things. This talk will explore the benefits that blockchains provide and how they could be used to enhance everyday interactions. https://rakutentechnologyconference2016.sched.org/event/8ChI/blockchain-systems-without-boundaries Rakuten Technology Conference 2016 http://tech.rakuten.co.jp/

2. “The new Rakuten Blockchain Lab (RBL) will be our first step toward unlocking
blockchain’s potential to revolutionize the way that financial and e-commerce
transactions are conducted. We want to not only prepare for that change, but take a
leading role in making it happen.”
Yasafumi Hirai
Group Executive Vice President, CIO, CISO and head of the Technology Division
"These days, blockchain, the technology on which bitcoin is based, is hailed as having
the potential to revolutionize financial services. Keen to explore its potential, we opened
the Rakuten Blockchain Lab (R.B.L.) in Belfast in August, and are beginning to
experiment now with applications in both the fintech and e-commerce sectors.”

8. Combination of the following features:
Trust is an inherent feature of a Blockchain
• Authenticity – Every action is associated with a Private Key
• Immutability – Once committed, transactions cannot be altered
• Transparency – Data is shared across all nodes in the chain
• Consistency – Transactions that cause conflicts get resolved automatically
• Consensus – All data in the chain is the same across all nodes
