Smart contracts are the next version of automated contracts where the user won't have to rely on trust. Smart contracts are automated algorithmic digital forms of contracts where parties can exchange assets without any intermediaries based on specified rules. Here, the program within the smart contract will self-execute based on the conditions previously defined by the parties.
There are certain benefits to using smart contracts such as autonomous, secured, interruption-free, trustless, cost-effective, fast performance, and accurate and error-free. But here, we will analyze the examples of smart contracts, such as how it can be useful in digital identity, supply chain management, insurance, etc.
To help you understand how smart contracts work or how you can utilize this new form of technology for your personal gain, or company 101 Blockchains offers an array of courses. You can use these courses to learn more about smart contracts and its role in various sectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

59. Ethereum Full Node
●
●
●
●
●
●
● Requires significant and growing hardware and
bandwidth resources
● May require several days to fully sync when first
started
● Must be maintained, upgraded, and kept online to
remain synced
70. Keys
Private keys are not used directly in the Ethereum system.

71. Public Key Cryptography and Cryptocurrency
In Ethereum, we use public key cryptography (also known as asymmetric cryptography) to create the
public–private key pair.
Together, they represent an Ethereum account by providing, respectively, a publicly accessible account
handle (the address) and private control over access to any ether in the account and over any authentication
the account needs when using smart contracts.
The private key controls access by being the unique piece of information needed to create digital signatures,
which are required to sign transactions to spend any funds in the account. Digital signatures are also used to
authenticate owners or users of contracts
Ethereum transaction is basically a request to access a particular account with a particular Ethereum
address
84. Transaction Structure (Cont…)
● The transaction message structure is serialized using the Recursive Length Prefix
(RLP) encoding scheme.
● All numbers in Ethereum are encoded as big-endian integers, of lengths that are
multiples of 8 bits.
● The data are separated by fixed length. No label is included for any field in
transaction serialization.
● There is no “from” data in the address identifying the originator EOA. That is because
the EOA’s public key can be derived from the v,r,s components of the ECDSA
signature. The address can be derived from the public key.
89. Concurrency
Ethereum, by definition, is a system
that allows concurrency of
operations (nodes, clients, DApps)
but enforces a singleton state
through consensus.
90. Concurrency Problem
Now, imagine that you have multiple independent wallet applications that are generating transactions from
the same address or addresses.
Example Scenario:
An exchange processing withdrawals from the exchange’s hot wallet (a wallet whose keys are stored
online, in contrast to a cold wallet where the keys are never online).
There are more than one computer processing withdrawals, so that it doesn’t become a bottleneck or
single point of failure. However, this quickly becomes problematic, as having more than one computer
producing withdrawals will result in some thorny concurrency problems, not least of which is the
selection of nonces.
How do multiple computers generating, signing, and broadcasting
transactions from the same hot wallet account coordinate?
91. Potential Solutions:
You could use a single computer to assign nonces, on a first-come first-served
basis, to computers signing transactions.
97. Transaction Value and Data
● The main "payload" of a transaction is contained in two fields: value
and data.
● Transactions can have 4 valid combinations;
a. only value - Payment
b. only data - Invocation
c. both value and data - Payment and Invocation
d. neither value nor data.- Empty Transaction
●
102. Transmitting Data to Contract
The data will be interpreted by the EVM as a contract invocation. Most
contracts use this data more specifically as a function invocation, calling the
named function and passing any encoded arguments to the function.
The data payload is a hex-serialized encoding of:
The function arguments
The function’s arguments, encoded
according to the rules for the various
elementary types defined in the ABI
specification.
A function selector
The first 4 bytes of the Keccak-256 hash of
the function’s prototype. This allows the
contract to unambiguously identify which
function you wish to invoke.
112. Deleting a Smart Contract
● Contract’s code cannot be changed
● By Removing the code and its Internal state (storage) from its address,
- Leaving a blank account.
● Executing an EVM opcode called SELFDESTRUCT
● Costs “negative gas,” a gas refund (Incentive for releasing network resources)
● Does not remove the transaction history (past) of the contract. - IMMUTABILITY
● SELFDESTRUCT capability will only be available if the contract to have that
functionality.
113. Introduction - Ethereum High-Level Languages
EVM is a virtual machine that runs a special form of code called EVM bytecode
● Any high-level language could be adapted to write smart contracts
● a number of special-purpose languages have emerged for programming
smart contracts.
Declarative (Functional) programming languages (Haskell and SQL)
Imperative (Procedural) programming languages ( C++ and Java)
Hybrids include Lisp, JavaScript, and Python
114. ● In smart contracts, bugs literally cost money.
● It is important to write smart contracts without unintended effects.
● We must be able to predict expected behavior of the program.
● Most widely used language for smart contracts (Solidity) is imperative.
● So, declarative languages play a much bigger role in smart contracts than
they do in general-purpose software.
Why Declarative Language?
116. Solidity
● Created by Dr. Gavin Wood (coauthor of this book)
● Explicitly for writing smart contracts
● The main "product" of the Solidity project is the Solidity compiler, solc,
● Converts programs written in the Solidity language to EVM bytecode.
● Each version of the Solidity compiler compiles a specific version of the
language.
118. What are Tokens
Commonly used to refer to privately issued special-purpose coin
- like items of insignificant intrinsic value,
- i. e. Transportation, food courts, and game tokens.
Nowadays, "tokens" administered on blockchains are redefining the word to
mean blockchain-based abstractions that can be owned and that represent
- Assets,
- Currency, or
- Access rights.
119. Traditional Vs Blockchain Tokens
Traditional Tokens
Restricted to specific businesses,
organizations, or locations,
Physical tokens are not easily
exchangeable and typically
have only one function.
Blockchain Tokens
these restrictions are lifted
Many blockchain tokens serve
multiple purposes globally &
Can be traded for each other /
for other currencies
120. How are Token Used
Most obvious use of tokens is as digital private currencies
This is only one possible use, Currency is just the first application:
Tokens can be programmed to serve many different functions
What can be those difference Functions?
121. How are Token Used
Currency - Serve as a form of currency, with a value determined through private trade
Resource - Earned or Produced
Asset - Represent ownership of tangible/ intangible asset
Access - Access rights and grant access to a digital or physical property
Equity - Shareholding in a DAO or legal entity
122. How are Token Used
Voting - Voting rights in a digital or legal system.
Collectible - Digital / physical collectible
Identity - Digital / legal identity
Attestation - Certification / attestation of fact by authority / decentralized reputation system
Utility - access or pay for a service.
123. Tokens & Fungibility
“In economics, fungibility is the property of a good or a
commodity whose individual units are essentially
interchangeable."
Tokens are fungible when we can substitute any single
unit of the token for another without any difference in its
value or function.
126. What is CryptoKitties??
CryptoKitties is a blockchain-based game in which one can breed, collect and hold kittens
that are made and generated over Ethereum blockchain
These cryptokitties are just like humans that are unique and cannot be replicated, taken
away or destroyed by anyone
Cryptokitties are a new form of collectibles which one can trade, buy, sell, collect like
traditional collectibles
The unique thing is that one can even breed this form of crypto-collectibles and the result
will be a totally unique new offspring!
The ownership will be tracked and everything will be recorded securely on a transparent
blockchain of Ethereum
127. Tokens & Fungibility
Fungibility is the property of a good or a commodity
whose individual units are essentially interchangeable.
Tokens are fungible when we can substitute any single
unit of the token for another without any difference in its
value or function.
Non-fungible tokens are tokens that each represent a
unique tangible or intangible item and therefore are not
interchangeable.
128. Counterparty Risk
Risk that the other party in a transaction will fail to meet their obligations
Some transactions suffer additional counterparty risk if there are more than two parties
involved.
when an asset is traded indirectly through the exchange of a token of ownership
- Custodian of the asset
- Ie. such as a certificate, deed, title, or digital token
In the world of digital tokens representing assets, as in the non digital world,
It is important to understand who holds the asset that is represented by the token
129. Token & Intrinsicality
Tokens that represent intrinsic assets do not carry additional counterparty risk
If you hold the keys for a CryptoKitty, you own it directly
- No other party holding that CryptoKitty for you
Conversely, many tokens are used to represent extrinsic things,
- Real estate, shares, trademarks, and gold bars
- Which are not "within" the blockchain, is governed by law, custom, and policy
- Token issuers and owners may still depend on real-world non-smart contracts.
- Extrinsic assets carry additional counterparty risk as they are held by custodians,
- i.e. Recorded in external registries, or controlled by laws outside the blockchain.
130. Token & Intrinsicality
Blockchain-based tokens has the ability to convert extrinsic
assets into intrinsic assets and thereby remove counterparty
risk.
Example:
Moving from equity in a corporation (extrinsic) to an
Equity or voting token in a DAO or similar (intrinsic)
organization
133. Token Standards - ERC20
First standard was introduced in November 2015 by Fabian Vogelsteller as an Ethereum Request
for Comments (ERC). It was automatically assigned GitHub issue number 20, giving rise to the
name "ERC20 token." The vast majority of tokens are currently based on the ERC20 standard.
ERC20 is a standard for fungible tokens, meaning that different units of an ERC20 token are
interchangeable and have no unique properties.
The ERC20 standard defines a common interface for contracts implementing a token, such that any
compatible token can be accessed and used in the same way.
134. Token Standards - ERC20
Here’s what an ERC20 interface specification looks like in Solidity:
contract ERC20 {
function totalSupply() constant returns (uint theTotalSupply);
function balanceOf(address _owner) constant returns (uint balance);
function transfer(address _to, uint _value) returns (bool success);
function transferFrom(address _from, address _to, uint _value) returns
(bool success);
function approve(address _spender, uint _value) returns (bool success);
function allowance(address _owner, address _spender) constant returns
(uint remaining);
event Transfer(address indexed _from, address indexed _to, uint _value);
event Approval(address indexed _owner, address indexed _spender, uint _value);
}
Consists of a number of functions that must be present in every implementation of the standard,
as well as some optional functions and attributes that may be added by developers.
135. ERC20 required functions and events
An ERC20-compliant token contract must provide at least the following functions and events:
TotalSupply - Returns the total units of this token that currently exist. ERC20 tokens can have a
fixed or a variable supply.
BalanceOf - Given an address, returns the token balance of that address.
Transfer - Given an address and amount, transfers that amount of tokens to that address, from
the balance of the address that executed the transfer.
TransferFrom - Given a sender, recipient, and amount, transfers tokens from one account to
another. Used in combination with approve.
136. ERC20 required functions and events
Approve - Given a recipient address and amount, authorizes that address to execute several
transfers up to that amount, from the account that issued the approval.
Allowance - Given an owner address and a spender address, returns the remaining amount that
the spender is approved to withdraw from the owner.
Transfer - Event triggered upon a successful transfer (call to transfer or transferFrom) (even for
zero-value transfers).
Approval - Event logged upon a successful call to approve.
137. Why Many Smart Contract Use Cases
Are Simply Impossible
138. Smart Contract
When smart people hear the term “smart contracts”, their imaginations tend to run wild
A smart contract is just a fancy name for code that runs on a blockchain, and interacts
with that blockchain’s state.
A smart contract is a piece of code that is stored on an blockchain, triggered by
blockchain transactions and which reads and writes data in that blockchain’s database.
Each Language has its strengths and weaknesses – you’d be crazy to build a website in C or
compress HD video in Ruby.
But in principle at least, you could if you wanted to. You’d just pay a heavy price in terms of
convenience, performance, and quite probably, your hair.
139. Use Case 1: Contacting External Service
Smart Contract that changes its behavior in response to some external event.
First User Case:
An agricultural insurance policy pays out conditionally based on the quantity of
rainfall in a given month.
Because source is outside the blockchain, there is no guarantee that every node will
receive the same answer.
Possible Solution:
The smart contract waits until the predetermined time, retrieves the weather report
from an external service and behaves appropriately based on the data received.
140. Use Case 1: Contacting External Service
Problem:
Because the source is outside of the blockchain, there is no guarantee that every
node will receive the same answer. Since the smart contracts are executed
independently by every node.
Perhaps the source will change its response in the time between requests from
different nodes, or perhaps it will become temporarily unavailable. Either way,
consensus is broken and the entire blockchain dies.
141. Use Case 1: Contacting External Service
Workaround:
Oracle pushes the data onto the blockchain rather than a smart contract
pulling it in.
Instead of a smart contract initiating the retrieval of external data, one or more
trusted parties (“oracles”) creates a transaction which embeds that data in the
chain. Every node will have an identical copy of this data, so it can be safely used
in a smart contract state computation.
146. 3. Hiding Confidential Data
Every Smart contract is owner of its data and it has full control over it.
It's impossible for other Smart Contract to read data directly.
148. What smart contract are for?
Blockchains enable data disintermediation, and this can lead to significant
savings in complexity and cost.
In a peer-to-peer financial ledger, each transaction must preserve the total
quantity of funds, otherwise participants could freely give themselves as much
money as they liked.
There are two dominant paradigms, inspired by Bitcoin and Ethereum.
