The Mathematics of Bitcoin — SHA256. "Blockchains will replace networks with markets." This is the Caucasian wisent, a species of European bison extinct since 1927.
It was poached into non-existence after settlement by humans in the mountains of the Western Caucasus. It long survived predation by the Caspian tiger and Asiatic lion but not the presence of humans. The Caribbean monk seal was native to the Caribbean and is believed to be extinct. The seals were extensively slaughtered by humans in the 18th and 19th centuries for the oil in their blubber. The last confirmed sighting was in between Jamaica and the Yucatán Peninsula in 1952. I don't want to be a bummer, so here is a link to donate to the World Wildlife Fund. The WWF, founded in 1961, carries out global conservation work, helping protect threatened species and their habitats. support.worldwildlife.org/site/SPageServ… Charity Navigator rating:charitynavigator.org/index.cfm?
Announcing txstats.com. BitMEX Research and Coin Metrics are happy to announce the release of txstats.com, the successor to P2SH.info, an independent project created by Coin Metrics’ Lead Data Engineer, Antoine Le Calvez.
Bitcoin stored by P2SH address type (Screenshot from txstats.com) Txstats.com is a collaboration between BitMEX Research and Coin Metrics with the aim of providing in-depth, high quality and timely information about how the Bitcoin network is used. Txstats.com provides a series of dashboards centered around a specific element of Bitcoin transactions such as: P2SH transaction statistics, Multi-signature usage data,SegWit transaction statistics, Lightning Network channel data,OP_Return statistics, Bech32 adoption,Replace by Fee usage,Data related to the Block Size Debate, Fee Estimation. BitMEX Research and Coin Metrics intend for txstats.com to be dynamic and will add more statistics to the website based on community feedback. Hash function simply explains... How Bitcoin Works in 5 Minutes (Technical) The Essence of How Bitcoin Works (Non-Technical) Ever wonder how Bitcoin (and other cryptocurrencies) actually work? How Bitcoin Works Under the Hood.
Bitcoin Timestamp Security. This final attribute is what enables Bitcoin to have a controlled release of the supply of bitcoins.
Otherwise Bitcoin would suffer from rapid inflation whenever the hashrate increased. But it turns out that this attribute assigns quite a bit of utility to the Bitcoin protocol and also makes it possible for folks to use Bitcoin as a data anchor for other services. Because we have reasonably strong assurances that timestamps fall within a given range and we have mathematical assurance of the amount of energy required to rewrite the blockchain history, Bitcoin provides a sound anchor for timestamping of data. But how reliable is it? Bitcoin’s Timestamp Flexibility In order for the time field of a block header to be considered valid by nodes it must meet two criteria: The first rule makes sense — we obviously don’t want anyone claiming to be from the future and it’s very easy for nodes to reject such claims because we’re all in general agreement about what time it currently is.
Maximum Drag. Competing with Bitcoin Core. Abstract: We examine the power and dynamics of the “Bitcoin Core” software project and we draw distinctions between the various different ways one can compete with the project.
We address the misconception that the Bitcoin Core software repository has the unique capability to change or prevent changes to Bitcoin’s consensus rules. We also discuss some common misconceptions and explain that if the Bitcoin Core repository becomes hijacked by nefarious actors or deleted, Bitcoin should be largely unaffected.
