These slides go over the post blockchain P2P platform Holochain (HOT crypto). It is NOT blockchain. the network validates the histories of each user and kicks out any bad actors. It is in alpha, but should have some releases by the end of 2020.
Using the Cloud Foundry and Kubernetes Stack as a Part of a Blockchain CI/CD ...Altoros
These slides exemplify how to employ the tools available through Cloud Foundry and Kubernetes to enable a continuous integration and continuous delivery pipeline on blockchain.
Blockchain technology is a distributed ledger platform that provides open and transparent transaction information with integrity and non-repudiation based on modern cryptography. It is also the technology behind many cryptocurrencies. This presentation will give fundamental knowledge on how blockchain works, its cryptography implementation, cryptocurrency definition and related terms and also blockchain use cases.
Web3 Security: The Blockchain is Your SIEMTal Be'ery
2021’s hottest new tech term, according to TechCrunch, was “definitely Web3”. Web3, as its name suggests, is considered by many as the future of the internet: decentralized, permissionless, and based on modern blockchain technology. While Web3 might have a bright future, it’s in the middle of growing pains: A number of Web3 apps were hacked in 2021, leading to theft of cryptoassets valued at hundreds of millions of US Dollars. In this talk we will present Web3 app technology, dissect new attack surfaces, and suggest new and exciting defense mechanisms.
First, we will dive into the technical details of Web3 applications, showing how Web3 technology opens new attack surfaces by moving app functionality onto the blockchain. We will then analyze these newly-exposed attack surfaces by reviewing a few examples we’ve discovered “in the wild.”
While Web3 exposes new attack surfaces, it also provides novel detection opportunities. Specifically, the public and transparent nature of the blockchain allows security researchers to immediately explore full details of any attack and, as a result, leads to quick and thorough discoveries. This is a paradigm shift in security research, as current practices only allow a few to learn actual attack details, only some portions of which are shared publicly. This shift in transparency allowed us to independently explore the aforementioned attacks.
Furthermore, we believe we can do even better and go beyond rapid post-mortem reports. We will show how the same raw data we had previously used for a post-mortem analysis can be analyzed in real-time (or even ante factum by “taking a peek” into the blocks that have yet to be mined) to detect and even prevent attacks. This capability is enabled by the online nature of the blockchain and its inherent block time delays. In fact, we can import, with relevant modifications, many of the principles and learnings of current web defenses, including Web Application Firewall (WAF) into the realm of blockchain. By doing so, we introduce a scheme for a Web3 Application Firewall (W3AF) which can greatly improve Web3 security and blockchain-based apps.

Web3’s red pill: Smashing Web3 transaction simulations for fun and profitTal Be'ery
The introduction of Web3 smart contracts has opened unlimited opportunities for decentralized apps (dApps) and users. With smart contracts, anything that can be coded can be deployed by anyone on the blockchain. As a result, in a Web3 environment, the users’ blockchain transactions, previously merely used for sending coins to peers, are now, in fact, Remote Procedure Calls (RPCs) for smart contracts.
The flip side of this expressiveness is that it’s almost impossible to know analytically in advance what would be the outcome of such RPC to an arbitrary smart contract. Attackers abuse this observability gap to trick users into signing transactions that are harmful in reality. This situation bears a close resemblance to the desktop environment: users need to evaluate in advance if a particular program behavior will be benign.
To solve this gap, Web3 security has taken a page out of the desktop’s security book by using a sandbox-style emulation to evaluate the transaction's outcome before it gets sent to the blockchain. In Web3 lingo, such sandbox emulation is referred to as transaction simulation.
In this talk, we will present our newly discovered attack methods against Web3 simulations, including the first-ever Web3 red pill exploits that allow smart contracts to know that they are running in a simulation and as a result, need to behave differently.
We have tested our findings against numerous leading simulation providers in the Ethereum Virtual Machine (EVM) domain and found that they are indeed vulnerable to such attacks. As a result of our responsible disclosure, multiple (currently three) issues were fixed, and we were awarded bug bounties. We will explain these exploits in detail, including the research methodology allowing us to inspect simulators’ inaccessible inner workings.
We will conclude with new and enlightening insights we gained through this research regarding the true capabilities and limitations of Web3 simulations.

How to Avoid Crypto Scams - Crypto JBroJared Broker
Crypto scams are on the rise and getting more sophisticated every day. This presentation shows you how to protect your cryptocurrency and personal information. Check out Crypto JBro on Youtube.
This covers the Synthetix Network, a decentralized trading platform running on the Ethereum blockchain. It is controlled by smart contracts and the assets are synthetic, meaning they mimic the real world assets.
This short presentation covers the Orchid (OXT) crypto and VPN network. It is built on top of Ethereum and creates a secure Internet connection with the Orchid app.
Anyone can be a bandwidth provider by locking up (aka staking) some OXT coin and becoming part of their directory. They face many challenges since I'm not sure if VPN will be obsolete with so much privacy tech being born. They also have quite a few competitors. It was a highly educational study, none the less!
Learn how to gain intereset on your cryptocurrency by using certain services and wallets to help validate transactions. It's a pretty cool aspect of blockchain, crypto, and Proof of Stake algorithms.
Comparing Bitcoin and two of its forked cryptos: Bitcoin Cash and Bitcoin SV. The two forks wanted a larger block size in order to scale the network. The groups could not come to an agreement and the forking began!

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

1. What is Holochain? HOT
◇ Distributed P2P app (Happ) framework
◇ Hosted with a HoloPort, earns HoloFuel
◇ Everything on Holochain is a Happ
◇ Every Happ DNA creates a new network.
◇ Post blockchain tech (not blockchain)
◇ Similar to Git / BitTorrent with DHT
◇ Agent (user) centric - individual authority
Created by: CryptoJBro.com
2. Agents / Validation
◇ Each user maintains their own tamper proof
history on that Happ (aka source chain)
◇ Each agent (user) signs their source chain
with their private key. Validation at edges.
◇ Distributed Hash Table is sharded (split up)
and other users validate against sources.
Only a few need to validate, not whole net.
Created by: CryptoJBro.com
3. Holochain Terms
◇ DNA: The code for the Happ (rules), shared
by the users of the Happ
◇ Membrane: management of Happ members
◇ Immune System: random users validate all
the data, keeping it unbiased and reliable,
the ID of the attacker is shared
Created by: CryptoJBro.com
4. Benefits to User
◇ Own their data - encrypted, private keys
◇ Identity is secure
◇ No middle companies taking our data for
marketing, censoring and spying
◇ Scalable - more users make it faster and
more secure
◇ Happs can be less code and quicker
Created by: CryptoJBro.com
5. Limiting Bad Actors
◇ Each Happ has its own validation rules.
◇ There is consensus about the rules.
◇ When an attacker tries something malicious,
they change the rules and are kicked off.
◇ The ID of the attacker is known and ignored.
◇ Proof of Service: History of serving a Happ
