Bitcoin Tip: Be Consistent

● Blockstream announces Jade hardware wallet: Blockstream’s new Jade hardware wallet is open source, supports Bitcoin and Liquid networks, and is compatible with Blockstream Green for Android. ● Blockstream Satellite 2.0 supports initial block download: Blockstream outlines version 2.0 upgrades to their satellite service which include expanded Asia-Pacific coverage, additional bandwidth, and an updated protocol that enables a full node to complete an initial sync using only the satellite feed. Like email, Bitcoin is a protocol. It’s like an online version of cash. In August 2017, in a hard fork coin split, Bitcoin split into two cryptocurrencies, traditional Bitcoin and Bitcoin Cash (“BCH”). Fixing the inefficiency now reduces the number of changes that need to be made in the proposed schnorr, taproot, and tapscript soft fork. This week’s newsletter relays a request for comments on a proposed change to the BIP341 taproot transaction digest and briefly summarizes discussion about a new and more concise protocol for atomic swaps. 18808 causes Bitcoin Core to ignore any P2P protocol getdata requests that specify an unknown type of data. The new logic will also ignore requests for types of data that aren’t expected to be sent over the current connection, such as requests for transactions on block-relay-only connections.

With the updated logic, half of the protected slots are allocated to any onion and localhost peers, with onion peers receiving precedence over localhost peers. BIP157 support for sending filters to light clients over the peer-to-peer (P2P) network protocol. FILTERS in its version message. ● Organization of LN 1.1 specification effort: although LN protocol developers decided which efforts they want to work on for the next major version of the common protocol, they’re still working on developing and coming to agreement on the exact specifications for those protocols. ● Formal specification of miniscript: Dmitry Petukhov published a formal specification of miniscipt based on the documentation written by other developers. ● Copay enables CPFP for incoming transactions: Version 9.3.0 adds the ability for the user to speed up an incoming transaction using child-pays-for-parent. ● HWI 2.0.0 is the release for the next major version of HWI. ● Why is block 620826’s timestamp 1 second before block 620825? Andrew Chow and Raghav Sood clarify that a block header’s timestamp field is not required to have a greater value than previous blocks. Onion peers have historically been disadvantaged by the eviction criteria due to their higher latency relative to IPv4 and IPv6 peers, leading to users filing multiple issues.

139), https://www.youtube.com/ a next step will be to extend eviction protection to I2P peers, as they generally have higher latency than onion peers. You’ll have the conceptual foundations you need to engineer secure software that interacts with the Bitcoin network. This ensures that multi-homed nodes can better inform the network of their network connectivity. A separate index was created for Ethereum, which can be found here. Since a route may cross more than a dozen channels, that means every bitcoin controlled by the attacker can prevent more than a dozen bitcoins belonging to honest nodes from being used for honest routing. This may seem unnecessary given that BIP32 already provides extended private keys (xprvs) that can be shared between signing wallets. Several LN implementations were already announcing or allowing multiple addresses of a given type, so this change brings the BOLT specification in line with what the implementations were already doing. 751 updates BOLT7 to allow nodes to announce multiple IP addresses of a given type (e.g. IPv4, IPv6, or Tor). ● Coinbase withdrawal transactions now using batching: Coinbase has rolled out batch withdrawals that they estimate will reduce their load on the Bitcoin network by 50%. Instead of each withdrawal payment generating a single onchain transaction, multiple payments will be combined into a single transaction once every 10 minutes.

The article specifically finds that that the share of renewables that power the network decreased from 41.6% to 25.1% following the mining crackdown in China during the Spring of 2021. Miners previously had access to a substantial amount of renewables (during a limited part of the year) when they were still in China (i.e. hydropower during the wet season in the summer months), but this was lost when they were forced to move to countries such as the U.S. One of the most significant upgrades is the Taproot Update, which went live in 2021. Following the introduction of Segregated Witness (SegWit) in 2017, this update enhances the security of Bitcoin transactions by implementing the “MAST” technique, which obfuscates private transaction data. The blockchain uses the one-way mathematical algorithm to create a public key from the private key. Miners deploy their computers to solve resource-intensive mathematical problems-the miner that reaches the correct solution first has the privilege of adding the next block to the Bitcoin blockchain and receives a reward in the form of BTC for their trouble.
