Hi Bitcoin Dublin



I hope you can make the next meetup which is scheduled for Thurs 12th and is promising to be an excellent event



Event will include a joint talk about Bitcoin(details below), a proposal for a Bitcoin hackathon weekend, Bitcoin beginners classes to be discussed as volunteers needed(we have found a free space to use), and of course further discussion in Bull & Castle



Content of talk

Michael Clear & Donncha O'Cearbhaill will speak on cryptography and security aspects of Bitcoin



Michael will look at Bitcoin from an attackers perspective, assuming ideal software implementations of Bitcoin, so the scope of attacks considered will be on the protocol and the crypto schemes used. Time permitting, Michael will give an overview of attacker models and double spending attacks, and look at the security of the crypto schemes used in Bitcoin. Some reasons will be considered as to why these particular schemes were chosen and why specific parameters were chosen.



Donncha will focus on the applied security for Bitcoin, giving a high level overview of how Bitcoin keypairs and transaction signatures allow Bitcoin "ownership" to be determined. Donncha will give a tutorial about how to make an offline wallet and securely send coins by signing a transaction offline and then broadcasting it, must have knowledge for those serious about Bitcoin :)



Doors open at 6.30 and talk begins at 7
