The July 2015 forks were two block chain forks with two or more invalid blocks. They were caused by miners who didn't properly validate blocks before mining on top of them.[1]| en.bitcoin.it
Weak blocks, or “near blocks” are not a new idea. In short, have miners propagate what amounts to mining shares over the p2p network, which allows PoW-backed sharing of data. Historical discussions of weak blocks centered around the blocksize and scaling debate, which means there was intense focus on reducing the marginal bytes sent per weak block to aid “gigameg blocks”. There was seemingly a lot of focus on creating DAGs, extra-consensus chains, and similar mechanisms for increasing...| Delving Bitcoin
Mark “Murch” Erhardt and Mike Schmidt are joined by Gregory Sanders to discuss Newsletter #299.| Bitcoin Optech
This week’s newsletter describes a proposal to improve capital efficiency on LN using tunable penalties. Also included are our regular sections with summaries of top questions and answers from the Bitcoin Stack Exchange, announcements of new releases and release candidates, and descriptions of notable changes to popular Bitcoin infrastructure software.| Bitcoin Optech
This week’s newsletter summarizes a discussion about submitting transactions directly to miners, links to a set of recommended taproot test vectors for wallet implementations, and includes our regular sections about preparing for taproot, new releases and release candidates, and notable changes to popular Bitcoin infrastructure projects.| Bitcoin Optech
Compact block relay is a protocol that allows two nodes with roughly similar sets of unconfirmed transactions to minimize both the bandwidth and the latency required to transfer a block that confirms many of those same transactions.| Bitcoin Optech
This week’s newsletter describes a proposal for a new managed joinpool protocol and summarizes an idea for relaying transactions using the Nostr protocol. Also included is another entry in our limited weekly series about mempool policy, plus our regular sections summarizing notable questions and answers posted to the Bitcoin Stack Exchange, listing new software releases and release candidates, and describing notable changes to popular Bitcoin infrastructure software.| Bitcoin Optech
Transaction pinning is a method for making fee bumping prohibitively expensive by abusing node protections against attacks that can waste bandwidth, CPU, and memory. This can make fee management more difficult in multiparty contract protocols (such as LN).| Bitcoin Optech
