Blockchains
A blockchain is a type of distributed ledger technology (DLT) that consists of growing lists of records, called ''blocks'', that are securely linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). The timestamp proves that the transaction data existed when the block was created. Since each block contains information about the previous block, they effectively form a ''chain'' (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. Blockchains are typically managed by a peer-to-peer (P2P) computer network for use as a public distributed ledger, where nodes collectively adhere to a consensus a ...

Ethereum
Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether ( Abbreviation: ETH; sign: Ξ) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Additional founders of Ethereum included Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin. In 2014, development work began and was crowdfunded, and the network went live on 30 July 2015. Ethereum allows anyone to deploy permanent and immutable decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide a broad array of financial services without the need for typical financial intermediaries like brokerages, exchanges, or banks, such as allowing cryptocurrency users to borrow against their holdings or lend them out for interest. Ethereum also allows users to create and exchange NFTs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
StarkWare Industries
StarkWare Industries is an IsraelI software company that specializes in cryptography. It develops zero-knowledge proof technology that compresses information to address the scalability problem of the blockchain, and works on the Ethereum platform. In May 2022 the company's estimated value was $8 billion, an increase from $2 billion six months earlier. History StarkWare Industries was founded in 2018 by Eli Ben-Sasson (President) from the Technion, one of the founders of Zcash, his former phd. student Michael Riabzev, Uri Kolodny (CEO), and Alessandro Chiesa from UC Berkeley (chief scientist). In April 2019 Technion sued Ben-Sasson and Riabazev for violating its Intellectual property The institute claimed that Ben-Sasson established StarkWare clandestinely, for his academic research without consent and demand 50% of his Stakeholder (corporate), stake in the company. Ben-Sasson claimed that he didn't use any invention belonging to the Technion, merely based on StarkWares� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polytechnic University Of Catalonia
The Technical University of Catalonia ( ca, Universitat Politècnica de Catalunya, , es, link=no, Universidad Politécnica de Cataluña; UPC), currently referred to as BarcelonaTech, is the largest engineering university in Catalonia, Spain. It also offers programs in other disciplines such as mathematics and architecture. UPC's objectives are based on internationalization, as it is one of Europe's technical universities with the most international PhD students and the university with the largest share of international master's degree students. UPC is a university aiming at achieving the highest degree of engineering/technical excellence and has bilateral agreements with several top-ranked European universities. UPC is a member of the Top Industrial Managers for Europe network, which allows for student exchanges between leading European engineering schools. It is also a member of several university federations, including the Conference of European Schools for Advanced Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The publication was founded by Henry Luce in 1929. The magazine competes with '' Forbes'' and '' Bloomberg Businessweek'' in the national business magazine category and distinguishes itself with long, in-depth feature articles. The magazine regularly publishes ranked lists, including the ''Fortune'' 500, a ranking of companies by revenue that it has published annually since 1955. The magazine is also known for its annual ''Fortune Investor's Guide''. History ''Fortune'' was founded by '' Time'' magazine co-founder Henry Luce in 1929 as "the Ideal Super-Class Magazine", a "distinguished and de luxe" publication "vividly portraying, interpreting and recording the Industrial Civilization".

Coinbase
Coinbase Global, Inc., branded Coinbase, is an American publicly traded company that operates a cryptocurrency exchange platform. Coinbase is a distributed company; all employees operate via remote work and the company lacks a physical headquarters. It is the largest cryptocurrency exchange in the United States by trading volume. The company was founded in 2012 by Brian Armstrong and Fred Ehrsam. In May 2020, Coinbase announced it would shut its San Francisco, California headquarters and change operations to remote-first, part of a wave of several major tech companies closing headquarters in San Francisco in the wake of the COVID-19 pandemic. History 2012–2019: founding and early years Coinbase was founded in June 2012 by Brian Armstrong, a former Airbnb engineer. Armstrong enrolled in the Y Combinator startup incubator program and received a $150,000 cash infusion. Fred Ehrsam, a former Goldman Sachs trader, later joined as a co-founder after noticing Armstrong's posts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base (blockchain)
USD Coin (USDC) is a digital stablecoin pegged to the United States dollar. USD Coin is managed by a consortium called Centre, which was founded by Circle and includes members from the cryptocurrency exchange Coinbase and Bitcoin mining company Bitmain, an investor in Circle. USDC is issued by a private entity and should not be confused with a central bank digital currency (CBDC). Usage USDC is primarily available as an Ethereum ERC-20 token, and on blockchains including Hedera Hashgraph, Algorand, Avalanche, Solana, Stellar, and TRON. Reserves Circle claims that each USDC is backed by a dollar held in reserve, or by other "approved investments", though these are not detailed. The wording on the Circle website changed from the previous "backed by US dollars" to "backed by fully reserved assets" in June 2021. USDC reserves are regularly attested (but not audited) by Grant Thornton, LLP, and the monthly attestations can be found on the Centre Consortium's website. History ...

Proof Of Stake
Proof-of-stake (PoS) protocols are a class of consensus mechanisms for blockchains that work by selecting validators in proportion to their quantity of holdings in the associated cryptocurrency. This is done to avoid the computational cost of proof-of-work schemes. The first functioning use of PoS for cryptocurrency was Peercoin in 2012. Description For a blockchain transaction to be recognized, it must be appended to the blockchain. In the proof of stake blockchain the appending entities are named ''minters'' or (in the proof of work blockchains this task is carried out by the miners); in most protocols, the validators receive a reward for doing so. For the blockchain to remain secure, it must have a mechanism to prevent a malicious user or group from taking over a majority of validation. PoS accomplishes this by requiring that validators have some quantity of blockchain tokens, requiring potential attackers to acquire a large fraction of the tokens on the blockchain to m ...
