Here is a suggested learning path for getting started with blockchain and smart contracts development:
1. Learn the fundamentals of blockchain technology - how it works, key components, types of blockchains.
2. Understand cryptography basics - hashes, digital signatures, public/private key encryption.
3. Learn the Solidity programming language for writing Ethereum smart contracts.
4. Build simple smart contracts and deploy them to testnets.
5. Learn how to develop decentralized applications (dApps) using smart contracts.
6. Explore blockchain development platforms like Ethereum, Hyperledger, etc.
7. Learn frontend libraries like Web3.js for interacting with blockchains.
8.
Ethereum is an open-source blockchain platform that offers smart contract facilities. Solidity was first introduced as a new type of programing language for the Ethereum platform. Developers use the Solidity programming language to develop smart contracts. Using Solidity, you can program the contracts to do any type of task.
Solidity is a type of object-oriented programming language. This programing language is developed specifically for smart contracts. This type of language is widely used in creating smart contracts features in blockchain platforms.
To understand Solidity better developers, need to dive into the key elements of this language, such as the compiler, pragma, reserved keywords, value types, variables, etc. There are already many use cases of using Solidity as the foundation for smart contracts. However, this language also has its fair share of issues.
Here, at 101 blockchains, we are offering courses that will help you comprehend this topic in a simple manner. Using our courses, you will understand the concepts behind Solidity and Smart contracts in no time.

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.

Smart contracts and NFTs call for a revised approach to store data. In these slides, 3 options for distributed and fault-tolerant data storage are presented:
IPFS
Filecoin
Arweave
Demonstrating how to create an end-to-end Web-based application that uses blockchain for user authentication, read, and write access to the data stored on the blockchain
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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).

8. Ether (ETH)
Ether is the native
cryptocurrency of the Ethereum
network. It is used to pay for
transactions and smart contract
execution, and it is also used as
a form of payment for gas.
Solidity
Solidity is the primary
programming language used
for writing smart contracts on
the Ethereum network. It is a
contract-oriented, high-level
language for implementing
smart contracts.
SMART
CONTRACTS
These are self-executing contracts with
the terms of the agreements directly
written into lines of code. Smart
contracts are used to facilitate, verify,
and enforce the negotiation or
performance of a contract.
Ethereum Virtual
Machine (EVM)
EVM is the runtime environment for
smart contracts in Ethereum. It is a
virtual machine that executes the
code of smart contracts on the
Ethereum network.
Ethereum Blockchain
“Ethereum is a blockchain with a computer embedded in it. It is the foundation for
building apps and organizations in a decentralized, permissionless, censorship-
resistant way.”
9. Ethereum Gas
“Ethereum gas is a unit of measurement for the computational effort required to
execute transactions on the Ethereum blockchain.”
Gas prices in Ethereum are dynamic and
determined by market demand. When the
demand for gas is high, the gas price
increases, and when demand is low, the
gas price decreases.
Gas is required for every transaction and
smart contract execution on the
Ethereum network, and is used to pay for
the computational resources consumed
by the nodes that validate and execute
the transactions. The amount of gas
required for a transaction or smart
contract execution is dependent on the
complexity of the operation

15. Solidity Language
Solidity is a high-level, contract-oriented programming language that is used for
writing smart contracts on the Ethereum -compatible blockchain
● Solidity developed specifically for the Ethereum platform and is influenced by
C++, Python, and JavaScript.
● Solidity is designed to provide a simple and secure way to create self-executing
contracts that enforce the rules and conditions of an agreement between parties
● Solidity contracts are executed on the Ethereum Virtual Machine, which is built
into the Ethereum blockchain and allow developers to create decentralized
applications and automate the transfer of digital assets based on the conditions
encoded in the contract.
● Supports features such as multiple inheritance, user-defined types, events,
modifiers which makes it possible to write complex, feature-rich smart contracts
16. Examples of Smart Contracts
A smart contract is a computer program that automatically executes the terms of a contract
when certain conditions are met.
