bitcoin

The concept of Bitcoin was first proposed by Satoshi Nakamoto on November 1, 2008, and officially came into existence on January 3, 2009. Bitcoin is a peer-to-peer, decentralized cryptocurrency that does not rely on a central authority for issuance, but rather completes transactions through a proof-of-work consensus mechanism on the blockchain, commonly known as "mining." Bitcoin uses a distributed database of P2P network nodes to confirm, verify, and record currency transactions, with a total issuance of 21 million coins.

first_img Blockstream executive Peter Bain: Institutional clients are optimistic about the Bitcoin bull market

Blockstream Chief Marketing Officer Peter Bain stated in a recent interview that Bitcoin has maintained the $81,000 mark amid stock market sell-offs, rising 10-year U.S. Treasury yields, and turmoil in Europe, which he described as "a very, very strong signal." He made this statement during a conversation with Grace Remington and Sean Hagan.Bain emphasized that technological development precedes price and discussed topics such as adoption, stablecoins, and tokenized stocks. He introduced Blockstream's new center established in Lugano and a new consulting department aimed at institutional clients, while explaining why treasury companies are mainly concentrated in the United States and why Switzerland will become the next market—Switzerland's clear regulatory framework and strong banking foundation make it an ideal launch market.Regarding quantum computing, Bain believes that the related threats will take decades to materialize, and that Bitcoin's real weaknesses lie elsewhere. He referenced the PHP vulnerability incident, stating that the industry needs to rethink the way software is released, and introduced Blockstream's research on quantum-resistant signature solutions, how consensus can be reached for quantum upgrades, and the Bitcoin Security Alliance. Additionally, he provided the first update on the Liquid Network event progress: the exchange service has been restored, the network is back online, and users can transfer Bitcoin back to the main chain. Looking ahead to 2027, Bain stated that institutional clients believe Bitcoin "is expected to usher in a major bull market."

first_img Electrum Bitcoin wallet fixes the theft vulnerability with a fee increase

On October 24, the Bitcoin lightweight wallet Electrum disclosed a malicious server attack targeting transaction fee increases and fixed it in version 4.8.3, corresponding to GitHub security advisory GHSA-6jp4-8v48-cc5v. Users may inadvertently sign funds over to the attacker when performing regular fee increases on transactions. Developers stated that the issue arose after users reported losing funds after signing fee increases.The results of two reports differed: one person discovered that transactions in the wallet history were replaced after broadcasting a payment and claimed that the original payment did not enter the Bitcoin peer-to-peer network and was withheld by the server; another person, Raju-K12, reported losing funds due to the fee increase on the replaced transaction. In the attack, the malicious server withheld new transactions broadcasted by the client and inserted a conflicting transaction into the history, replacing the original output with the attacker's address. The replacement transaction was signed invalidly at that time, but the lightweight client did not verify these signatures before displaying unconfirmed transactions; after the user manually increased the fee and signed through RBF, the attacker received the funds. Both individuals claimed that the last four digits of the attacker's address were the same as those of the legitimate receiving address. The announcement did not disclose the amount stolen, transaction identifiers, or the attacker's address.The patch corresponds to commit 90fe308, which checks the signatures of the wallet's own inputs before writing memory pool transactions to local history, but does not overwrite inputs from external addresses of the wallet and does not perform complete consensus verification. The announcement suggests that users who have not upgraded should verify the output address and amount each time they sign; clients connected to their own or trusted servers are not affected by this attack. On the timeline, the issue was first privately disclosed on October 11, received reports of fee loss on October 18, the fixed version was tagged on October 23, and the binary and public disclosure occurred on October 24.
