In the next web lecture by Lucy Temple, we will discuss blockchain as upcoming technology that also can be of interest for SSC.

The most interesting characteristic of blockchains is the fact that it brings parties together, which do not necessarily trust each other but have trust in the blockchain technology and underlying mechanics. The web lecture will:

• Introduce the basic components of a blockchain and its key characteristics,
• Discuss the use and application of blockchain technology in cities,
• Identify some existing challenges to this technology.

Main Takeaways

• A blockchain is a type of database, a system for recording information, the most common is a digital ledger that can be described as a linked list or sequence of blocks, which hold transaction records.
• Contrary to classical systems, blockchains work in a decentralized way, thus, there is no central authority, and therefore no central point of failure.
• Blockchain technology can help guarantee the security, transparency, and anonymity of elections, referendums, and public consultations.
• They also come with their very specific challenges such as privacy leakage, scalability and selfish mining.
