Join us tonight as we talk all things Bitcoin multi-signature followed by a Q&A for any general questions you might have about Bitcoin. Multi-signature (multisig) refers to requiring multiple keys to authorize a Bitcoin transaction, rather than a single signature from one key and it has a number of applications.

We'll be joined by Neil Woodfine (@nwoodfine), Head of Marketing at Unchained Capital (@unchainedcap) where he has led sales and marketing teams across a variety of bitcoin-industry verticals since 2014, including exchange (Okcoin), cross-border payments (Remitsy and Wyre), and infrastructure (Blockstream). Neil currently leads marketing at Unchained Capital, helping get more bitcoin keys into more hands. Neil is a leading voice in the bitcoin industry and has featured in Bloomberg, Wall Street Journal, Financial Times, Reuters, and the BBC.

You already hold your own bitcoin keys and keep them safely offline, but how secure is your wallet from someone with a wrench in meatspace? Distributing control of your bitcoin across multiple keys using multisig offers protection from this kind of scenario, as well as improving your security against remote attacks, supply chain attacks, and more. Neil provides an overview of what multisig is, how it works, why you might want to use it, and recommends some of the best solutions for deploying multisig for your bitcoin holdings.

There will be FREE pizza, beer & soft drinks.

Approximate timings:
6.00pm - Arrive, chat, drinks & pizza
6.30pm - Neil Woodfine - Bitcoin multisig: Resisting £3.67 wrench attacks + Q&A
7.30pm - General Q&A

When we finish at 8pm, members wanting to chat further are welcome to join other members at the Prince of Wales pub near Cardiff Central train station.

This is an open meetup for anyone who has an interest in cryptocurrencies whether you're a beginner or an expert and we look forward to seeing you on the night.
