UNIVERSITY OF COLORADO BLOCKCHAIN ALLIANCE

Advancing interdisciplinary research, education, and community engagement around blockchain technologies and applications

The University of Colorado Blockchain Alliance (UCBA) was founded to integrate efforts across academic institutions, research institutions, industry leaders, foundations, and government organizations to advance the technologies, applications, governance, and effects of distributed ledger technologies (DLT) in our society.



UCBA is at the center of DLT and Blockchain interdisciplinary research, education, and community engagement across multiple departments at the University of Colorado and its member network.

What is a crypto wallet?

A crypto wallet is an electronic device or software that helps you store your cryptocurrencies offline. Cryptocurrency wallets work by encrypting your coins and holding the private keys.

How do crypto wallets work?

Crypto wallets store your cryptocurrencies offline, meaning that they are not connected to the internet. When you want to spend your cryptocurrencies, you will need to connect your crypto wallet to the internet and send the appropriate amount of cryptocurrency to the address on the screen.

What is the predefined business logic within a blockchain called?
A blockchain is a distributed database that enables secure, transparent and tamper-proof record-keeping. Each block in a blockchain contains a cryptographic hash of the previous block, a timestamp, and transaction data. Businesses can use blockchain to create immutable, auditable records of transactions. The predefined business logic within a blockchain is called a smart contract. Smart contracts are self-executing contracts that automate the execution of transactions and agreements between parties.
What is Accenture's role in multi-party system blockchain?
Accenture is a global professional services company that provides strategy, consulting, digital, technology and operations services. The company has been involved in blockchain technology since 2015 and is a member of the Hyperledger Project, an open source collaborative effort created to advance cross-industry blockchain technologies. Accenture is also a founding member of the Global Blockchain Business Council. In 2017, Accenture launched a multi-party system blockchain platform called BlockApps STRATO. The platform allows users to build, test and deploy blockchain applications quickly and easily.
How do crypto kitties work?
Crypto kitties are digital assets that are stored on the Ethereum blockchain. Each kitty has a unique set of genes that determines its appearance, and they can be bred to create new kitties with different genes. Kitties can also be traded on an open market.
Crypto Currency And How It Works
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009. Cryptocurrencies are often traded on decentralized exchanges and can also be used to purchase goods and services.
What is blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is an Ethereum blockchain?
An Ethereum blockchain is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
What is a block in the blockchain?
In the blockchain, a block is a record of new transactions. When a block is completed, it is added to the chain. Blocks are chained together, with each block containing a cryptographic hash of the previous block.
What is a blockchain in simple terms?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

What is proof of stake blockchain?
A proof of stake blockchain is a type of distributed ledger that allows users to validate transactions and earn rewards based on their stake, or ownership, in the network. Unlike proof of work systems, which require users to expend energy to solve complex mathematical problems, a proof of stake system allows users to validate transactions and earn rewards simply by holding coins in their wallets. This system is more energy-efficient and environmentally-friendly than proof of work, and has the potential to provide greater security and stability for blockchain networks.
What is blockchain development?
Blockchain development is the process of developing a blockchain-based application. A blockchain is a digital ledger that records transactions in a secure, decentralized manner. This makes it ideal for applications that require a high degree of security and transparency.
What is layer 1 of the blockchain?
Layer 1 of the blockchain is the underlying infrastructure that allows for the existence of the blockchain. It is the foundation that the blockchain is built upon.
What is a blockchain NFT?
A blockchain NFT is a digital asset that is stored on a blockchain and can be used to represent ownership of real-world assets. NFTs are unique, non-fungible tokens that cannot be replicated or exchanged for other tokens.

What is the polygon blockchain?
The polygon blockchain is a type of blockchain that uses a directed acyclic graph (DAG) instead of a traditional linear chain. This allows for more efficient and scalable transactions.
