Vienna, September 25th, 2024 – Morpher GmbH, a blockchain trading platform for stocks, cryptos, forex, indices and unique markets such as sneakers and watches, has released an open source data oracle to improve access to reliable trading data. A blockchain oracle is a way of bringing data into a blockchain from external sources, including other blockchains. The oracles currently available suffer from the following problems: they have limited data availability, are not actually real-time, and have to battle licensing problems or usability problems (e.g. pull oracle data is visible before its being used). Oracles represent a single point of failure: if one of the currently available oracles goes down, so do all their feeds. This leaves blockchain applications depending on real-world data at a distinct disadvantage against regular platforms. To combat these shortcomings, Morpher’s Oracle has been built as an open source protocol, with multiple data sources aggregated. This allows for an increase in speed, accuracy, and reliability of data, which is a necessity for every settlement platform to operate. The Morpher Oracle comes in two flavors: a pull basedon-chain attestation data-service and a novel intent based oracle for EVM based chains. Both will include Data Feeds for US Equities, Commodities, Forex, and Crypto from the launch. The data is available in real-time, trustable, and able to be licensed to partners/developers. Morpher’s CEO Martin Froehler stated “Existing oracles could not power a real-time trading platform like Morpher. So we developed our own next generation, multi-sourced oracle which we are now making available to other projects on Radix and EVM chains.” Thomas Wiesner, Morpher’s CTO shares his vision for the oracle as "Our vision for the Morpher Oracle is to have the dev community continue to grow its robustness, adding more data streams, increasing the number of chains and further expanding the use cases past what we can currently imagine. We want to give a new tool to bring even more trust into blockchain." “We are super excited to see the release of the Morpher oracle live on Radix and available to use from today onwards - Morpher’s stack has already proven to be incredibly flexible and I look forward to what can be built, using their many data feeds, on Radix in the coming months.”
-Piers Ridyard, CEO of RDX Works Available to use today for all developers and see how quickly and accurately the Radix coin price is shown in USD. About Morpher Morpher, headquartered in Vienna, Austria, has been at the cutting edge of decentralized finance since 2018. The platform empowers users to trade virtual copies of real-world financial markets using its proprietary protocol and MPH token. Supported by prominent investors like Tim Draper, Morpher is dedicated to making global financial markets universally accessible. For more information, visit https://www.morpher.com/new.

10 Days of .Net Aspire: Day 4 — Using Oracle Component in Visual Studio 

Oracles are another interesting way to customize your experience in the Obyte ecosystem. They're like bridges that connect decentralized networks to the outside world. Distributed ledgers are excellent at securely storing and verifying data, but they can't access real-world information on their own. Oracles solve this by fetching data from external sources and feeding it into their system, enabling smart contracts to interact with real-world events, prices, and information. Oracles work by collecting data from various sources like APIs, websites, sensors, or other off-chain data providers. They upload this data to the chain and then you can find it by the address of the one who posted it (e.g., this is an Obyte oracle address, identical to any other wallet address: I2ADHGP4HL6J37NQAD73J7E5SKFIXJOT). Some oracles use a decentralized approach where multiple data sources are used to ensure accuracy and prevent manipulation. This mechanism helps ensure that the data is trustworthy and tamper-proof. On the other hand, you can easily set up your own personal oracle (data feed) for your specific use case, or let it be created by a close party, like a member of your family or coworker. This way, the oracle can offer any personalized information you can count on to make transactions among your inner circle, or with business partners. In Obyte, it’s possible to create your own oracle in a few minutes, without coding or technical steps. Potential Uses The use cases for oracles are vast and varied. In finance, they can provide real-time price feeds for cryptocurrencies and traditional assets, enabling decentralized finance (DeFi) applications like lending, trading, and insurance. In supply chain management, oracles can track and verify the status of goods in transit. They can also be used in gaming to bring in real-world events to affect gameplay, or in weather forecasting to trigger payouts in weather-based insurance policies. As for a personal oracle, the uses are only defined by yourself, because the data can only come from yourself. For instance, we can register the successful completion of a specific task by Alice (a daughter, a coworker, a partner, etc.). A conditional payment from the wallet could use this information to release funds automatically if we use that oracle address (the wallet address of the oracle operator) to create the smart contract (Chat – [Registered Contact] - Recipient’s address – Offer smart contract). **  ** Human or customized oracles could also work for rewards in family tokens. For example, parents can create an oracle that tracks if specific tasks are completed by their children. A supervisor (such as a parent) can create an oracle by sending data into the Obyte DAG, such as a task's completion status. When a child completes a task, the supervisor updates the oracle with a value like "Yes." The family token system can then automatically trigger a reward, sending the predefined tokens from the family treasury to the child’s wallet as a reward for completing the task. The same principle could apply to anything you like to use it for. Steps without coding First of all, you’ll need to download and back up an Obyte wallet, available as a light app for desktop and mobile. Next, in the “Receive” section, you can click “Get Me Coins” to buy some GBYTEs, needed for transaction fees —you’ll need around $0.00001 per transaction. There are other ways to buy GBYTEs with traditional money, and you can consult them in this full guide. Once the app is installed and with some GBYTEs available to spend, go to the “Send” section of the wallet. At the top of this page, you should see “What to send,” and a list below. From that list, instead of any asset, select “Data into datafeed (searchable).” To advance further, your account needs to be of a single address. If it’s not, then you’ll need to switch to your already created single-address account or create a new one from the main menu (Add account – Plain Account – Single Address Account). All new accounts are single-address by default. Beyond this, you’ll only need to fill the values of your data feed (oracle) in any way you want, including a name/title, and a result/answer. For instance, the name could be “Mary’s task,” and the result could be “Done.” Press “Send,” type your password if required, and that’s it! A small transaction fee will be taken from your wallet, and the oracle will be published on the Obyte DAG, available for everyone to consult —including smart contracts. **  ** Creating your own oracle here is easy, fast, secure, and inexpensive. Now, if you know how to code and want to make it more advanced, you can always check our documentation to create an oracle from scratch.

The family token system can then automatically trigger a reward, sending the predefined tokens from the family treasury to the child’s wallet as a reward for completing the task. The same principle could apply to anything you like to use it for. Steps without coding Steps without coding First of all, you’ll need to download and back up an Obyte wallet , available as a light app for desktop and mobile. Next, in the “Receive” section, you can click “ Get Me Coins ” to buy some GBYTEs, needed for transaction fees —you’ll need around $0.00001 per transaction. There are other ways to buy GBYTEs with traditional money, and you can consult them in this full guide . Obyte wallet Obyte wallet Get Me Coins Get Me Coins this full guide this full guide Once the app is installed and with some GBYTEs available to spend, go to the “Send” section of the wallet. At the top of this page, you should see “What to send,” and a list below. From that list, instead of any asset, select “Data into datafeed (searchable).” To advance further, your account needs to be of a single address. If it’s not, then you’ll need to switch to your already created single-address account or create a new one from the main menu (Add account – Plain Account – Single Address Account). All new accounts are single-address by default. Once the app is installed and with some GBYTEs available to spend, go to the “Send” section of the wallet. Beyond this, you’ll only need to fill the values of your data feed (oracle) in any way you want, including a name/title, and a result/answer. For instance, the name could be “Mary’s task,” and the result could be “Done.” Press “Send,” type your password if required, and that’s it! A small transaction fee will be taken from your wallet, and the oracle will be published on the Obyte DAG , available for everyone to consult —including smart contracts.

I was inspired to write this blog post after reading a paper called "The Oracle Problem — Why Decentralising Everything is More Difficult than it Sounds" by Victor Hogrefe. As the title suggests, Victor argues that there are no good solutions for handling oracles on the blockchain. It may have been true six years ago when the paper was written, so kudos to Victor for proposing some potential ones back then. However, what struck me the most was that the author failed to consider that the oracles themselves can be decentralized. In this post, I'll explain why it's actually "not that difficult" to decentralize everything and how this issue has already been solved with the help of decentralized oracles. But first, let's take a small step back and learn what oracles are exactly. The Role Of Oracles Smart contracts are designed in a way to provide deterministic results. Their job is to take input, execute logic, and modify the state of the blockchain irreversibly. But the majority of events still happen off-chain. Allowing smart contracts to interact with these events has always been a double-edged sword. On one hand, this significantly increases the potential blockchain use cases but on the other —  poses serious security risks and trust issues. Oracles are here to help. They act as a bridge between blockchains and the external world and enable smart contracts to execute code based on real-world events and conditions. For example, to be able to bet on the outcome of a tennis match between Roger Federer and Novak Djokovic, you need a way to tell the smart contract who won. Since we don't live in the Metaverse yet, a smart contract can't know the outcome of the match — someone has to tell it who the winner is, so that the contract can payout to the winners. The big question is: who will be the one to tell the smart contract who won? We would need to trust this person or entity to be correct and honest... But wait a minute... Trust? That's not how things work in Web3. We don't want to trust. We want trustless. Decentralized Oracles In the original paper I mentioned in the beginning, the author overlooks the possibility of oracles being decentralized and is rather focused on discussing different algorithmic solutions, weaknesses, and potential attack vectors. What he doesn't consider is that the oracles themselves can be decentralized. Decentralized oracles, unlike the normal ones, rely on multiple independent nodes to fetch and validate information. This means there's no single point of failure, making it much harder to compromise the system. By using various mechanisms, such as multiple data sources, multiple oracles, or the need to have a stake in the system, decentralized oracles can prevent different sorts of malicious attacks, data corruption, or bribery. One such mechanism has been implemented by the UMA Protocol. UMA's Optimistic Oracles UMA is a leader in the oracles space, alongside Chainlink, which is the largest oracle protocol in the world. UMA's oracle system consists of two main components: the Optimistic Oracle and the Data Verification Mechanism (DVM). The principle is straightforward: anyone can submit an answer on-chain, and a dispute arises only if the answer is incorrect. The first layer of UMA's oracle system is the Optimistic Oracle. This layer is designed to quickly verify data optimistically, meaning that all submitted statements are true by default unless challenged. The second layer is the DVM (Data Verification Mechanism), which serves as a fallback for the Optimistic Oracle by resolving disputes if they occur. The entire system is efficient and cheap because it aims to prevent disputes in the first place. Here’s how it works: A smart contract requests a piece of data and sets a dispute period.
A proposer posts a bond and submits the data.
If no one disputes the data within the dispute period, the data is finalized, and the proposer gets their bond back.
If a dispute arises, the disputer posts a bond equal to the proposer’s bond and escalates the dispute to the DVM.
UMA token holders resolve the dispute within 48 hours. If the disputer is correct, they receive the proposer's bond as a reward, and vice versa. Use Cases Apart from the obvious use cases for oracles in DeFi, UMA's optimistic oracles offer much more flexibility, as practically anything can be submitted as a data point. Here are some projects that utilize UMA's Optimistic Oracles: Polymarket Polymarket is a decentralized predictions market, one of the most prominent DeFi apps lately. On Polymarket, you can place your bets on pretty much anything — from the winner of the Presidential Elections in 2024 to how many tweets Elon Musk will post this month Sherlock Sherlock is a risk management platform designed for DeFi. They run extensive DeFi audit contests where many security researchers compete for a bug bounty. Cozy Cosy is an open-source insurance protocol that allows users to provide and receive protection against predefined conditions, like a loss of funds or smart contract hacks. The use cases are quite diverse already and with the upcoming RWA narrative, the amount of projects using UMA's OOs will only get bigger. RWA Tokenization RWA tokenization is one of the most promising opportunities in crypto. It has the potential to unlock multi-trillion dollar markets and onboard millions of people into DeFi. Major institutions are launching tokenized funds, and the role of Oracles in this market is as important as it's ever been. Blackrock's BUIDL fund uses Chainlink to track real-world assets like US Treasury bill prices, dollar yields, etc. It allows investors to purchase tokens representing shares in the fund with "safe" assets and offers unmatched liquidity. As the sector grows, the demand for fast and accurate Oracle infrastructure and reliable data will grow significantly. Protocols like Chainlink, UMA, and Pyth are well-positioned to capture the majority of this market share. Conclusion We brought smart contracts to the world; now, it's time to bring the world into smart contracts. Allowing smart contracts to interact with the outside world seems like the next logical step in blockchain development. While DeFi remains one of the most promising and straightforward ways to onboard the next billion users, there are many ways in which oracles can be used: they can provide real-world data for various applications, from financial products and insurance to gaming and supply chain management. Decentralized oracles ensure that this data is accurate and trustworthy without relying on a single point of failure, opening a world of new possibilities for the technology.

Step 1: Install the necessary libraries To connect to a database and query data, you need to install the following two libraries: pandas: A Python library for data analysis, including functions for reading and writing data.
sqlalchemy: A Python library for interacting with relational databases, allowing you to use Python with various databases. You can install these libraries using the following command in the command prompt or terminal: pip install pandas
pip install sqlalchemy Step 2: Connect to the database Connecting to a database requires the following information: Database Type: The type of database you want to connect to, such as MySQL, PostgreSQL, etc.
Host Name: The host name or IP address where the database is located.
Port Number: The port number of the database, usually the default port number.
Username: The username required to connect to the database.
Password: The password required to connect to the database.
Database Name: The name of the database you want to connect to. You can use the following Python code to connect to the database: from sqlalchemy import create_engine

# Connect to a MySQL database
engine = create_engine('mysql://username:password@hostname:port/databasename')

# Connect to a PostgreSQL database
engine = create_engine('postgresql://username:password@hostname:port/databasename')

# Connect to an Oracle database, requires cx_Oracle library to be installed
engine = create_engine('oracle+cx_oracle://username:password@hostname:port/databasename') Step 3: Query data using the read_sql function Use the read_sql function from pandas to query data from the database. The read_sql function requires two parameters: SQL Query: The SQL query you want to execute.
Database Connection: The database connection you created earlier. Here is an example of querying data: import pandas as pd

# Execute SQL query and store the result in a DataFrame
df = pd.read_sql('SELECT * FROM mytable', engine)

# Print the DataFrame

How to Connect to Oracle, MySql and PostgreSQL Databases Using Python

Introduction Proficiency in database management is an essential skill for data analysts. Oftentimes, colleagues from different departments need quick access to specific datasets, making the traditional method of exporting Excel files from databases inefficient and time-consuming. A more effective approach involves creating new user accounts in the database and granting them appropriate viewing rights. This allows colleagues to seamlessly connect to the database using tools like Power BI or Power Query, enabling them to access necessary data tables promptly and efficiently. This streamlined process fosters collaboration and supports decision-making across organizational departments. data-driven Creating a new user To create a new user in the Oracle database, you can execute the following SQL command: CREATE USER 'USERNAME' IDENTIFIED BY 'PASSWORD'; For example: CREATE USER TEST_USER IDENTIFIED BY TEST123; Granting the Connect Role After creating a new user, attempting to connect may result in an error message: [72000][1045] ORA-01045: user TEST_USER lacks CREATE SESSION privilege; logon denied To enable the user to connect to the database, you must grant the CONNECT role: GRANT CONNECT TO TEST_USER; Merely connecting is not enough - make sure to grant the RESOURCE privilege to allow access to the tables. GRANT CONNECT, RESOURCE TO TEST_USER; Table privilege To grant specific privileges on tables to a user, you can utilize the GRANT command on specific table TO user. For example: GRANT SELECT ON schema.table_name TO TEST_USER; If you wish to provide the user with options beyond selection, such as insertion, updating, and deletion, you may proceed with the execution of the following command. GRANT SELECT, INSERT, UPDATE, DELETE ON schema.table_name TO TEST_USER; Delete a user To remove a user from the database, you can execute the following SQL command: DROP USER TEST_USER; Thank you for taking the time to explore data-related insights with me.

Database Management: Creating and Granting User Access in Oracle

Using Python to Save a Dataframe into Oracle Database You can use the library in combination with the and libraries to save a dataframe to an Oracle database in Python. pandas sqlalchemy cx_Oracle import pandas as pd
from sqlalchemy import create_engine
import cx_Oracle

# Create an SQLAlchemy engine using the connection
engine = create_engine('oracle://username:password@hostname:port/service_name')

# Save the dataframe to the Oracle database and lowercase your_table_name 
df.to_sql('your_table_name', con=engine, if_exists='replace', index=False) Replace , , , , and with your actual Oracle database credentials and connection details. 'username' 'password' 'hostname' 'port' 'service_name' Please replace with the actual lowercase name of the table in your Oracle database. Otherwise, you may encounter . your_table_name InvalidRequestError: Could not reflect: requested table(s) not available in Engine When you run this script, it will establish a connection to the database, create a sample dataframe, and then save the dataframe to the specified table in the Oracle database. Oracle Make sure the table structure has been created in the database before proceeding. Option 1: Create Table Structure using SQL Keep in mind that you will need to create the table structure in the Oracle database before attempting to save the dataframe to it. The table structure should match the structure of the dataframe in terms of column names and data types. You can create the table structure in your Oracle database using SQL. Here's an example of how you might create a table in Oracle to match the structure of your dataframe: CREATE TABLE your_table_name (
    column1_name  column1_data_type,
    column2_name  column2_data_type,
    ...
); Option 2: Create Table Structure using Python You can run the SQL script in Python using the method provided by the SQLAlchemy library. Here's an example of how you can execute an SQL script after creating the engine: engine.execute() from sqlalchemy import create_engine

# Create an engine
engine = create_engine('oracle://username:password@hostname:port/database_name')

# SQL script to create a table
sql_script =
CREATE TABLE your_table_name (
    column1_name  column1_data_type,
    column2_name  column2_data_type,
    ...
);

# Execute the SQL script
with engine.connect() as connection:
    connection.execute(sql_script) Make sure to replace , , , etc., with your actual table and column names and data types. your_table_name column1_name column1_data_type Conclusion Once the table structure is in place, you can then use the method I mentioned earlier to save the dataframe to the Oracle database. The method will automatically insert the data from the dataframe into the existing table in the database as long as the column names and data types match. to_sql Thank you for taking the time to explore data-related insights with me.
