Kalshi and Polymarket announce the launch of perpetual contract trading, as the prediction market platform accelerates its entry into the derivatives space

According to CoinDesk, the prediction market platform Kalshi is preparing to launch cryptocurrency trading in the United States, expanding beyond its core prediction market business. According to insiders, the platform plans to initially introduce perpetual contracts linked to cryptocurrencies like Bitcoin.This move will put Kalshi in more direct competition with cryptocurrency platforms like Coinbase. Coinbase currently does not offer true perpetual contracts in the U.S., but has launched "perpetual-like" futures contracts with long durations and has expressed intentions to introduce more advanced derivatives products within the U.S.Kalshi holds several licenses from the U.S. Commodity Futures Trading Commission (CFTC) and has recently been approved to offer margin trading, positioning it to enter the derivatives market. Insiders say the company expects to start with cryptocurrency-linked perpetual contracts and may expand this model to other asset classes in the future.Kalshi's competitor Polymarket also announced on X plans to launch perpetual futures on its platform, but did not disclose further details. A video in the tweet shows that users will be allowed to trade leveraged long and short positions on assets like gold, NVIDIA, BTC, AAPL, and indicates that registration will provide early access.

Coinbase: Ethereum, Solana, and other PoS chains may face quantum risks

According to Decrypt, Coinbase's Quantum Computing and Blockchain Independent Advisory Committee released a report on Tuesday stating that proof-of-stake (PoS) blockchains may face a greater risk of exposure to future quantum computing attacks, as the cryptography relied upon by the validator signatures that protect these networks could ultimately be cracked by sufficiently powerful quantum computers. The report points out that PoS networks like Ethereum and Solana rely on cryptographic signatures—Ethereum validators use BLS signatures, while Solana validators and users use Ed25519 signatures—to help the network reach consensus on blocks and maintain consensus.The advisory committee stated, "PoS chains have exposure risks in the signature schemes used by validators to protect the network, which means that the challenges faced by PoS are not just about upgrading wallets; parts of the core consensus mechanism itself may need to be redesigned." The report mentioned recent work by Ethereum developers, including a proposal by co-founder Vitalik Buterin in February to replace BLS validator signatures, KZG commitments, and ECDSA wallet signatures with quantum-resistant alternatives.The committee also listed the digital signatures used in cryptocurrency wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins belong to the category where the public keys are already visible on-chain. The report stated that the current cryptocurrency system remains secure, as quantum computers capable of breaking modern cryptographic signatures do not yet exist.
