Fast Multiparty Threshold ECDSA with Fast Trustless Setup

Steven Goldfeder

Digital signatures authorize transactions in cryptocurrencies

• Alice's device, containing her private key, is a single point of failure

Multiparty authentication

• Instead of having a single device store your key material...
  • You can split it into multiple devices

• Designed your address as protected by multiple keys

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

The basic idea here is to substantiate the claims made by this square post:
http://corner.squareup.com/2011/06/postgresql-data-is-important.html

In PostgreSQL, and MySQL (MyISAM and InnoDB) I create millions of rows and then add 
and remove columns and add and remove indexes.  For columns without defaults this is
basically free in PostgreSQL and O(n) in MySQL.  For adding indexes its at best O(n) 
everywhere, but with PostgreSQL it claims not to do any locking that would otherwise
prevent table interaction.

Also, PostgreSQL has _awsome_ documentation (it has real examples!). I always get
