BITCOIN CLASSIC HAS TURNED THE WORLD UPSIDE DOWN!Steven Rhyner
Â
Thirty-six days have already passed since the new hard fork of Bitcoin, under the name Bitcoin Classic, came into being. The core developers believe that a hard fork is a last resort, something that you shouldn’t do unless you have to.
An overview of blockchain, cryptocurrencies, Bitcoin, Ethereum, ICOs. Meant to be introductory level but provide a slightly higher level of detail. Includes some companies to watch in the blockchain space. Prepared before the August 1 fork, which did occur.
Bitcoin is the world's first cryptocurrency, a form of electronic cash. It is the first decentralized digital currency: the system was designed to work without a central bank or single administrator.
The shape of money is transforming - it's becoming digital. Bitcoin is emerging as the digital currency of the world and this document provides information about Bitcoin.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
Â
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Â
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
Â
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Â
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

13. BITCOIN XT
Fork of Bitcoin Core, first release December 27, 2014
Initially intended to support Lighthouse crowdfunding platform
Lead dev Mike Hearn
14. THE HARD FORK
June 22, 2015: Gavin Andresen proposes an increase for max block size
August 6, 2015 Andresen's proposal was merged into the XT codebase
August 15, 2015 version 0.11A was released to the public
15. THE HARD FORK
The forks activates after 75% of the blocks mined after the beginning of 2016
signal support
The block size will initially increase to 8MB and will double every two years
In 2036 the blocksize limit will be 8GB
18. THE PROBLEM
Signatures of Bitcoin transaction can be slightly altered without invalidating the
signatures (malleability bug)
This means that the txID can be altered
Malleated transactions are still valid, but transaction spending the malleated one are not
Hard to build second layer solutions and bi-directional payment channels
20. THE IDEA
Separate the signature data in a new field which is not considered to calculate
the txID
BTW it is also a blocksize increse
But you kinda need a hard fork for that
Maybe…
24. BITCOIN CLASSIC: THE FIRST COMPROMISE
Let’s increase the size limit to 2 MB
Let’s buy some time
Hard fork still required
25.
26. HONG KONG AGREEMENT
SegWit is expected to be released in April 2016
The code for the hard-fork will therefore be available by July 2016
If there is strong community support, the hard-fork activation will
likely happen around July 2017
28. SEGWIT RELEASE
Merged into Core 0.13.1 in October 2016
Implemented also by Bitcoin Knots and Bcoin
Requires 95% hashing power to activate
Miners signalling starts on November 15th
Expected to be activated quickly
29.
30. THE OPPONENT: BITCOIN UNLIMETED
Users can set the max blocksize they accept and produce
You accept some invalid blocks if there is enough work
Absolute max block size 32MB
35. WHAT IS UASF
Proposed by the anonymous developer ShaolinFry
Instead of using HP, users set a flag day where nodes start to
enforce the new rules
Economic majority set the rules
36. BIP 148
On August 1st 2017 nodes start refusing blocks that don’t
signal SegWit
Good community support
No major exchange declare support
40. THE NEW YORK AGREEMENT
After 2017 Consensus conference, DGC Barry Silber
organizes a meeting between Bitcoin companies’ CEO and
miners
They agree to activate the segwit2x upgrade, proposed by
RSK founder Sergio Demian Lerner
Requires a hard fork
41.
42. Believed to be a great compromise that will make
everybody happy
53. PROBLEMS WITH SEGWIT2X
SegWit is already a blocksize increase, we don’t really
need a 2x at the moment
Not enough time for nodes to upgrade
High risk of chain split , not really worth it
Mostly political
