In brief
Kadena, blockchain network initially developed by JP Morgan, has doubled in size and is now capable of 480,000 transactions per second.
Kadena claims it has achieved a high transaction speed by doubling the number of “braided chains” on its network to 20.
Blockchain networks like Kadena, Algorand, R3’s Corda, Polkadot and Blockstack have Ethereum as a common rival, whose slow yet popular network will increase in speed upon the launch of Ethereum 2.0.
Kadena, the network developed by JP Morgan’s in-house blockchainblockchain lab, has doubled in size and is now capable of 480,000 transactions per second, according to an announcement today from its team. EthereumEthereum, by comparison, supports about 14 transactions per second in its current iteration and the network, by far the most popular for decentralized applications (dappdapp), is struggling to support the traffic.
The Kadena blockchain, which has since spun out of JP Morgan to become its own entity, relies on the same proof-of-workproof-of-work mechanism as Ethereum, where computers duke it out to mine blocks using their processing power. But Kadena said that it has solved the scaling issue that prevents proof-of-work blockchains like Ethereum and BitcoinBitcoin from supporting limitless traffic.
The network has achieved its high transaction speed by doubling the number of “braided chains” on its network to 20. This refers to the interconnectedness of the Kadena network. The team claims that it could one day reach 1,000 chains, or “an ever-increasing number of chains.”
“Launching Kadena, and now expanding to 20 chains, proves that we can scale a layer-1 blockchain to the point where digital assets can go mainstream,” said Kadena Co-Founder and CEO Will Martino, in a statement.
Project Ubin, a blockchain-based multi-currency payments network created by the Monetary Authority of Singapore (MAS), JP Morgan, and state-investor Temasek, is ready for a commercial roll-out following the successful implementation of its prototype.
A Reuters report from July 13 confirmed the success of the prototype multi-currency blockchain, dubbed. In a joint press release, the MAS and Temasek said:
“An international settlement network, modeled after this payments network prototype, could e...
Kadena also claims to be “the fastest blockchain platform in the world," which is a claim it shares with many other blockchain networks.
Kadena joins dozens of blockchain networks, among them Algorand, R3’s Corda, Polkadot and Blockstack, that promise high throughput and low transaction fees. One blockchain network, Tectum, claims it can process more than 1 million transactions per second.
Their common rival is Ethereum, whose sluggish yet popular network will increase in speed upon the launch of Ethereum 2.0, the long-anticipated update to the Ethereum network, expected for release later this year or in early 2021.
ETH2 scaling for data will be available *before* ETH2 scaling for general computation. This implies that rollups will be the dominant scaling paradigm for at least a couple of years: first ~2-3k TPS with eth1 as data layer, then ~100k TPS with eth2 (phase 1). Adjust accordingly.
The winner of the pack will attract retail and institutional applications, as well as decentralized finance, the booming industry with over $6 billion worth of crypto locked into it—the lion’s share on Ethereum.
Kadena also announced that it has made Kadena Kuro, a private version of the Kadena blockchain, free of charge and open source.

French Pornhub users rushed to ProtonVPN this week after the adult site blocked access from France in protest of new government-mandated age verification rules, the company said, claiming that signups for the service surged 1,000% in just 30 minutes.
ProtonVPN is part of a suite of privacy tools developed by Proton AG, a Switzerland-based company best known for its encrypted email service, ProtonMail.
While ProtonVPN reported a 1,000% surge in French signups this week, it didn’t disclose the num...
Less than a month after the Pectra Upgrade, the Ethereum Foundation believes that the world’s second-largest crypto, both as a technology and as an ecosystem, is approaching major breakthroughs with higher stakes for a broader audience.
Yet those stakes could be at risk if the people steering it are entrenched in what it calls a messy process: shipping protocol.
"We must rethink our current approach to designing, developing, and stewarding the protocol," the foundation wrote Monday, announcing t...
Ethereum's blockchain capabilities should grow tenfold over the next year, the network's co-founder Vitalik Buterin said.
Speaking at ETHGlobal Prague 2025 last week, the crypto entrepreneur predicted that the crypto network behind the second biggest digital coin by market cap should improve costs and speed soon.
"In general, I do think there's a lot of room to scale safely," he said. "My view is that generally we should scale L1 by about 10x over the next year and a bit."
The network has fac...
