Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

1. 1
HTML (Hypertext MarkUP
Language)
HTML is the lingua franca for publishing hypertext on
the World Wide Web
Define tags <html><body> <head>….etc
Allow to embed other scripting languages to manipulate
design layout, text and graphics
Platform independent
Current version is 4.x and in February W3C released the
first draft of a test suite 4.01
For more info: http://www.w3.org/MarkUp/
2. 2
HTML (Hypertext Markup Language)
Example HTML code:
<HTML>
<head>
<title>Hello World</title>
</head>
<body bgcolor = “#000000”>
<font color = “#ffffff”>
<H1>Hello World</H1>
</font>
</body>
</HTML>
4. 4
HTML (Hypertext Markup Language)
Common features
– Tables
– Frame
– Form
– Image map
– Character Set
– Meta tags
– Images, Hyperlink, etc…
5. 5
HTML (Hypertext Markup Language)
File Extensions:
HTML, HTM
Recent recommendation of W3C is XHTML 1.0
combines the strength of HTML 4 with the
power of XML.
XHTML 1.0 is the first major change to HTML
since HTML 4.0 was released in 1997
More info: http://www.w3.org/TR/xhtml1/
6. 6
CSS (Cascading Style Sheet)
Simple mechanism for adding style to web page
Code be embedded into the HTML file
HTML tag:
<style type=“text/css”>CODE</style>
Also be in a separate file FILENAME.css
HTML tag:
<link rel=“stylesheet” href=“scs.css” type=“text/css”>
Style types mainly include:
• Font
• Color
• Spacing
7. 7

<p>
<?php
$cnt=0;
while($cnt <= 4)
{ $cnt++;
echo "Hello World<P>"; }
?>
</body></HTML>

19. 19
CGI (Common Gateway Interface)
Standard for external gateway programs to
interface with information servers such as HTTP
servers
Real-time execution
Main Objective:
• Dynamic Content
• User Interface
Current version 1.1
20. 20
CGI (Common Gateway Interface)
Various choice in Programming language
selections
C, C++, PERL, Python
PERL; most popular and widely used
Server side execution
Script runs as a stand alone process unlike PHP
Basic difference with PHP is the execution
approach
21. 21
PERL (Practical Extraction and Report
Language)
Commonly used PERL Libraries (Modules):
• CGI.pm
• DB.pm
• DBI.pm
• CPAN.pm
• Mysql.pm

Language)
Sample PERL code:
#!/usr/local/bin/perl5.6.1
## printenv -- demo CGI program which just prints its environment
##
print "Content-type: text/plainnn";
foreach $var (sort(keys(%ENV))) {
$val = $ENV{$var};
$val =~ s|n|n|g;
$val =~ s|"|"|g;
print "${var}="${val}"n";
}

Transport Layer Security
Two categories of cryptographic algorithms
• Conventional (Symmetric)
• Public Key (Asymmetric)
26. 26
Secured Web Server (HTTPS,
MOD_SSL)
Conventional or Symmetric
• Sender and Receiver share a key
Public key or Asymmetric
• Solve the key exchange issue
Certificate
• A certificate associates a public key with the real identity of
an individual, server
• Includes the identification and signature of the Certificate
Authority that issued the certificate
28. 28
