Trezor, the popular cryptocurrencies hardware wallet, introduced two firmware updates on its models Trezor T and Trezor One. Trezor T's new firmware will support more cryptocurrencies, according to the official announcement. These include Monero, Cardano, Stellar, Ripple, Tezos, Decred, Lisk, Zencash, Groestlcoin and Zcash Sapling Hardfork.
The Bitcoin Core development team recently updated its list of 73 Bitcoin startups that have announced plans to support SegWit. The list includes well-known Bitcoin wallet service providers Blockchain.info, AirBitz, BreadWallet, TREZOR, Samourai Wallet, Ledger Hardware Wallet, Electrum, GreenAdress, KeepKey and Mycelium.
A step is usually skipped between the hardware wallet and the entire node: the Electrum wallet not only connects to the hardware wallet, but also provides a wide range of features. Of course, this is more important for a technician or if you want to be a technician. After you start the Electrum application, it takes a few seconds to finally open your wallet. Second, you feel like you're back in the program design of the last decade.
The theory is that the domino effect on all major cryptocurrencies exchanges, which has led to a decline in the value of cryptocurrencies, is more likely and realistic than FUDs in the cryptocurrencies markets of China and South Korea.
Whether it's cold wallet technology or hot wallet technology, these two extremes can actually have a loss of security, or other feature sacrifices, it's not right. Now we are faced with the problem, is the characteristics of hot and cold wallet to us, such as cold storage, of course, cold storage at the beginning, 100% of everything is online, cold storage for many people are security guarantees, but lack of flexibility and mobility, and in cold storage, our speed is very low, but also need some human intervention.
Trezor this week released Trezor One's firmware update 1.9.1 and Trezor T-type device firmware update 2.3.1, which will fix a security vulnerability discovered three months ago related to isolated witness transactions.
Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.
Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
