"Web browser Opera now allows making payments with Bitcoin (BTC) directly inside the browser.
The company announced the news in a press release shared with Cointelegraph on Oct. 21, detailing that Opera’s 350 million users can now send and receive BTC directly from the browser, as well as use the cryptocurrency for purchasing goods and services on e-commerce websites.
Additionally, the browser now enables adding a Bitcoin and TRON (TRX) card into the built-in Crypto Wallet to keep track of the cryptocurrency owned. Charles Hamel, head of crypto at Opera, commented on the new feature launch.."
Of course, this is the 600001 block in Bitcoin, because it counts from scratch (as in the array). But it's still not bad :P
"Over the last eight weeks, the world has watched the yellow vest protests in France as the grassroots political movement has fought for economic justice. On Sunday, the well known street artist Pascal Boyart (Pboy) revealed a mural that contains a solvable puzzle with 0.28 BTC inside. The artist explained that the puzzle cannot be solved remotely and that sleuths must visit the location to decipher the painting’s clues.."
"The regime's use of cryptocurrency shows desperation," Guaidó said in a press conference in response to Maduro’s admission, according to Bloomberg. "To resort to that kind of subterfuge emphasizes the economic crisis the regime is going through," he said.
It’s a criticism that is more than a little curious, given previous public statements from Guaidó which expressed his affinity for Bitcoin and other cryptocurrencies. Way back in 2014, in fact, well before many other leading Latin American figures joined the fray, Guaidó was tweeting about Bitcoin and the promise it held for Venezuelans.
The Lightning Network (LN) is a second-layer scaling solution for Bitcoin that has been under development for several years. It is designed to allow more transactions to be processed – and at lower fees – without clogging the network.
There are currently three independent teams working on their own implementations of the LN protocol in different languages.
C-Lightning was developed by Blockstream while Eclair and Lightning Network Daemon (LND) were developed by ACINQ and Lightning Labs, respectively.
I came across this website which is from a BU node "detecting" double spends on the BCH chain. https://doublespend.cash/224.html#respends
Since there is no true provable timestamp on transactions the node can only use information on when it received the transaction into the mempool from the network. Presumably, the first one received is the original? But with network delays, this again is not provable.
In any case - you can see multiple examples of double spends, several of which are successful by just bumping the fee. So if this was zero conf, those funds are not actually confirmed, even though a user of the zero conf wallet would think they are.
Reading different websites about cryptocurrency I still see the same thing. The same chasing of XYZ cryptovalutes - be it Nano, Ethereum, Steem or EOS, which try to show Bitcoin as something outdated that doesn't change, while other cryptovalutes undergo revolutions of changes reaching higher and higher numbers of "Generations" to show their level of sophistication.
But there are solutions to increase Bitcoin scaling, Bitcoin has Smart Contracts, Bitcoin even develops its own blogging platforms. Is the altcoin era slowly coming to an end? I don't know, but it's worth educating people, especially when it comes to the fact that Bitcoin is not a outdated as people try to tell people. I would say something else - it is probably the biggest cryptocurrency that exists in terms of functionality.
Today I will show Smart Contracts on Bitcoin - the RSK project (RootStock).
