Private companies, as well as national and local governments, have all caught media attention for announcing some kind of investigation or at least interest in the blockchain. Of course, one of the most notorious examples of this was Long Island Iced Tea Corporation’s pivot to Long Island Blockchain Corporation.
On February 28, 2018, the Kenyan government announced it will appoint a task force to explore the use of distributed ledger technology and artificial intelligence over the course of a three-month tenure. Led by Dr. Bitange Ndemo, the 11-member task force has three months to produce a road map that will detail how these technologies can be applied at a local level. The task force includes Steve Chege, Safaricom’s head of corporate affairs, John Gitou, Michael Onyango, Dr. Charity Wayua, Fred Michuki and Juliana Rotich, a serial tech entrepreneur who co-founded BRCK and Ushahidi.
An eclipse attack is a network-level attack on a blockchain, where an attacker essentially takes control of the peer-to-peer network, obscuring a node’s view of the blockchain.
In a new paper titled “Low-Resource Eclipse Attacks on Ethereum’s Peer-to-Peer Network,” Sharon Goldberg, an associate professor at Boston University; Ethan Heilman, a Ph.D. candidate at Boston University; and Yuval Marcus, a researcher at the University of Pittsburgh, describe a way to carry out an eclipse attack on the Ethereum network.
(The researchers disclosed their attacks to Ethereum on January 9, 2018, and Ethereum developers have already issued a patch — Geth v1.8.1 — to fix the network.)
