The Kadena network, which is led by JPMorgan blockchain veterans, has gone live on Monday, with the firm announcing a new $20 million token sale. Kadena mainnet launch unlocks mining Kadena coins According to an announcement on Nov. 4, Kadena has launched its mainnet Chainweb alongside the Kadena token wallet Chainweaver. The firm is also planning to carry out its third token sale from Nov. 5–Nov. 22. As specified on Kadena’s website, the launch of Kadena’s mainnet means that miners can participate in the Kadena public blockchain network and mine for real Kadena coin. Co-founded in 2016 by early JPMorgan …

Ethereum 2.0 validators can expect to earn from 4.6% to 10.3% as rewards for staking on an annual basis, a senior ConsenSys exec says. 32 ETH required to become a validator Collin Myers, head of global product strategy at blockchain firm ConsenSys, reportedly claimed that in order to become a validator on the Ethereum 2.0, one is required to maintain a minimum amount of 32 Ether (ETH), which is worth $5,760 at press time. Myers revealed the news at a recent blockchain event Devcon 5, Coindesk reports Oct. 25. Ethereum 2.0 is a major network upgrade on the Ethereum blockchain …

Ethereum (ETH) co-founder turned Cardano (ADA) creator Charles Hoskinson believes that if Bitcoin (BTC) fails, the entire cryptocurrency industry could fail. Hoskinson made his remarks during an interview for the Off the Chain podcast on Oct. 10, hosted by Morgan Creek Digital Assets co-founder Anthony Pompliano. After multiple projects that included co-founding Ethereum, Hoskinson — a mathematician, cryptographer and entrepreneur — founded the peer-to-peer technology firm Input Output Hong Kong (IOHK) in 2015. As CEO of IOHK, Hoskinson created and launched the cryptocurrency Cardano in 2017, which uses a Proof-of-Stake (PoS) algorithm dubbed Ouroboros. Bitcoin: “blind, deaf and dumb by …

Bitcoin Core developer Greg Maxwell has criticized the “attractive mystery” that fear of a 51% attack on Bitcoin (BTC) entails, arguing that it betrays a fundamental lack of understanding about the cryptocurrency. In a Reddit post published on Oct. 5, Maxwell argued that any mechanism cooked up to mitigate the threat of a 51% attack always implies centralization and represents a far greater threat to Bitcoin’s integrity. Bitcoin’s fundamental focus As Cointelegraph reported previously, a 51% attack can occur on blockchains that use a proof-of-work (PoW) algorithm and essentially entails a user or group seizing control of the majority of …

Hedera Hashgraph, a decentralized public network targeting enterprises and claims to be capable of processing 10,000 cryptocurrency transactions per second (TPS), has publicly launched its beta mainnet this Monday. Despite the project’s governing council attracting membership from major multinational corporations — including IBM and reportedly Boeing — some analysts are expressing skepticism regarding Hedera’s representation of Hashgraph’s purported performance. Hedera introduces the Hashgraph algorithm Hedera first launched on March 13, 2018, with the project then comprising just a white paper and the Hashgraph consensus algorithm. Describing itself as a third-generation distributed ledger technology, the Hashgraph algorithm is described as a …

Blockchains and the related field of decentralized technologies represent a massive opportunity for humanity — not to mention the fact they appeared with almost perfect timing. Our largest institutions have become so powerful that they can take advantage of normal people without repercussions. Look no further than Facebook spying on its users and the surveillance state run by the Communist Party of China. Fortunately, blockchain technology, cryptography and other distributed systems act as a counterbalance to this extreme consolidation of power. They are defensive technologies that empower the many against the few. Like BitTorrent disrupting the music industry, cryptocurrencies and …

Ethereum co-founder Vitalik Buterin has proposed to using the Bitcoin Cash blockchain as a temporary scalability solution for the Ethereum network. The programmer introduced a summary of the idea in a July 13 post on the Ethereum Research. As previously reported, the Ethereum network has experienced some scalability issues, with its native blockchain capable of processing as few as 15 transactions per second (TPS), while its major competitor Ripple is reportedly estimated to have a TPS capacity of 1,500. As such, the Ethereum community has been working on Ethereum 2.0, a major network upgrade that is expected to improve its …

San Francisco-based tech firm Chia Network has released a green paper that describes an eco-friendly means of mining cryptocurrencies. The green paper provides a description of how proof-of-space and proof-of-time create a "Nakamoto-style" consensus algorithm for Chia’s blockchain. Specifically, Chia proposes to “farm” rather than mine to verify blockchains that issue cryptocurrencies, wherein proof-of-space and proof-of-time take the place of the proof-of-work (PoW) principle used for mining of Bitcoin (BTC) and Ethereum (ETH). The paper further explains: “Instead of using proofs of work, Chia alternates proofs of space with verifiable delay functions. This results in a chain than in many …

Ethereum (ETH) might decrease issuance ten-fold by 2021, said Justin Drake, an Ethereum 2.0 researcher at the Ethereum Foundation, as technology-focused news outlet Trustnodes reported on July 5. Drake reportedly set out a possible timeline, saying: “Here’s a possible timeline (dates likely totally wrong!) highlighting the key milestones: January 2020: beacon chain launch. June 2020: eth2 light clients production-ready. November 2020: eth1 fork #1 to have its fork choice rule honour eth2 finality (conservatively, no issuance reduced). March 2021: eth1 fork #2 to reduce issuance by 10x.” Drake further stressed that there are several non-technical issues which are harder for …

The first stage of the Ethereum network’s transition to Ethereum 2.0 is expected to take place on January 3, 2020, as said in a bi-weekly call of Ethereum core developers on June 13. During the call, Ethereum researcher Justin Drake said that the dev team is working on code specifications for phase zero, confirming that codes are still expected to be released on June 30. Phase zero is the name of the first transition stage of the Ethereum network from a proof-of-work to a proof-of-stake consensus algorithm, which would pass block validation function from miners to special network validators. As …

Adam Back, who invented the hashcash proof-of-work system and was one of the first people to work on bitcoin (BTC), spoke about the positive uses of blockchain at G20. Cointelegraph Japan reported on Back’s comments at a meeting of finance ministers and central bank governors in Japan on June 8. Sitting next to the governor of the Dutch central bank, Back said he believed blockchain was another move to open networking — and said financial institutions stand to benefit from the technology because it would mean international transfers no longer need to go through intermediary banks with questionable creditworthiness. When …
