Bitcoin’s new quantum defenses, 18.9M SOL cancelled: Hodler’s Digest

Bitcoin’s new quantum defenses, 18.9M SOL cancelled: Hodler’s Digest

Özet: Kripto piyasasında önemli gelişmeler yaşanıyor.

Despite considerable skepticism among Bitcoiners about how close the quantum threat to Bitcoin is, two stories this week highlighted the progress being made toward upgrading the blockchain and protecting outputs from attack.

StarkWare researcher Avihu Levy tested an experimental quantum-resistant transaction on the Bitcoin mainnet that protects it during the brief period when public keys are exposed in the mempool.

Onchain data shows that StarkWSare spent a 10,000-satoshi output protected by Levy’s Quantum Safe Bitcoin (QSB) scheme which combines hash-based one-time signatures with computational searches that bind an authorization to a specific transaction.

It’s more of a last resort than a practical measure, as each transaction takes hours and costs $150 to $200.

On August 27, Blockstream researchers published a Bitcoin Improvement Proposal to upgrade Bitcoin with the SHRINCS signature scheme.

The researchers have slimmed down a huge hash based post quantum signature by about 13.23 times — but it’s still nine times larger than Bitcoin’s existing signatures and comes with a bunch of trade offs.

Blockstream Research’s Jonas Nick called it “the first concrete proposal for a post-quantum signature scheme designed specifically for Bitcoin.” While he said it was “not optimal along every axis” he added:”I do think it is a very good trade-off among the options we have now,” he said.

At the end of the week, Bitcoin (BTC) is up 1.1% to trade at $78,420, Ethereum (ETH) is up 0.6% to trade at $2,469 and XRP (XRP) is down 8.7% to $1.38.

The total market cap is at $2.64 trillion according to CoinMarketCap.

Among the biggest 100 cryptocurrencies, the top three altcoin winners of the week are VeChain (VET) with an 18.5% gain, SPX6900 (SPX) on 17.3%, and Uniswap (UNI) on 15.2%.
