Hi Giuseppe,The switch is running rapid-pvst as visible from the show run output "spanning-tree mode rapid-pvst". However, it shows a different result when you do show spanning-tree command.

Configuring Peer-to-Peer Blocking - Cisco

In a new era of finance and investing in which people could finally break free from central banks' dominance and regain control of their assets.The Bitcoin white paper established a peer-to-peer electronic cash system (Image source)Unlike traditional fiat currencies, Bitcoin is created, stored, and traded on a distributed ledger known as the blockchain. A blockchain, at its core, is a decentralized database distributed across a global network of nodes. The network is immutable, which means that whenever a transaction occurs, new information is combined with the information in the previous block to form a stable chain. This network is secured by a set of participants called Bitcoin miners who verify and finalize transactions and create new blocks in a process called Bitcoin mining. Bitcoin mining is the process by which new Bitcoins enter circulation as a reward for miners using computational power to validate transactions. To accomplish this, Bitcoin mining uses a Proof of Work (PoW) consensus mechanism–the oldest and one of the most secure consensus algorithms.As mentioned, the blockchain is a decentralized database, meaning it has no centralized gatekeepers to verify the legitimacy of new transactions. This is why Bitcoin mining is employed to secure the network.In a POW model, miners compete with each other to solve arbitrary mathematical puzzles, using more and more computing power to produce a new block. This process can be quite costly and involves high electricity consumption, due to miners running powerful computers for long hours.The Proof-of-Work consensus mechanism was co-invented by computer scientist Cynthia Dwork in 1993 (Image source)The miner who wins this race by solving the puzzle first gets to verify and add the new set of transactions to the blockchain. Once the new block is added to the network, new Bitcoins enter circulation and are rewarded to the miner for their.

amusing fact about peer block - Peer to peer - On the internet

Most VPS service providers do not allow Bittorrent downloading due copyright issues. However, some people are not aware of this. And no matter how much this is explained there is always somebody using torrents to download movies. The best way is to stop the torrent traffic within xray-server altogether. But this is not easy.In theory the protocol could be blocked via this config below.Inbounds:"sniffing":{ "enabled":true, "destOverride":[ "http", "tls" ] }"routing":{ "domainStrategy":"IPIfNonMatch", "rules":[ { "type":"field", "outboundTag":"block", "protocol":[ "bittorrent" ] } ]}However this doesn't work reliably with VLESS-VISION-TCP-REALITY.Looking at the /var/log/xray/access.log I can see some packages are blocked and others go through. It can't block all of the connections, it will only slow this down.2023/07/07 16:39:13 140.228.xx:32368 accepted tcp:51.159.4.xxx:55463 [block]2023/07/07 16:39:13 140.228.xx:32012 accepted tcp:96.244.189.xxx:58946 [direct]2023/07/07 16:39:18 140.228.xx:29768 accepted tcp:ipv6.torrent.ubuntu.com:443 [block]2023/07/07 16:39:18 140.228.xx:29378 accepted tcp:torrent.ubuntu.com:443 [block]I'm using Bittorrent app on Android (from Playstore):As you can see there is no way to stop the peer-to-peer traffic.I know from experience, that this nDPI project works with Wireguard.But because V2Ray/Xray operates at the application layer of the network stack (as opposed to the network layer for Wireguard/OpenVPN), it doesn't need to alter IP packet headers, so there's no need for NAT or masquerading.The core challenge here is that the nDPI module is designed to operate at the network layer, inspecting packets directly. While Xray operates at the application layer, it doesn't mean nDPI or any L7 filter couldn't analyze its traffic. Xray, as a proxy tool, encrypts the traffic between the client and the server. This makes it challenging for a DPI tool like nDPI to determine the application-level protocol, because it cannot see into the encrypted data.Unless there was a way to hook that into the unencrypted traffic within Xray.So what can we really do to prevent Bittorrent properly?

Google is rolling out a new tweak for Google Hangouts that should make your calls to your friends sound a little bit better. According to VentureBeat, Google is now allowing people to make peer-to-peer connections to one another. That's not the default setup for every Google Hangout you have with another person, but it's something the Hangout app will aim for when it can. "To improve call quality and speed, Hangouts will route audio and video over a peer-to-peer connection when possible,"Google told VentureBeat. Google also elaborates on the point of peer-to-peer connections in a new addition to its Hangouts help page in Google Support. "To improve audio and video quality, Hangouts calls use a direct peer-to-peer connection when possible. This allows Hangouts to more efficiently route your call directly to the person you're talking to, rather than connecting the call through one of Google's servers," reads Google's description. "Note: A direct peer-to-peer connection between you and the other person reveals both your IP addresses. With an IP address, it's possible to approximate your location." Recommended by Our Editors On the plus side, it's not as if a person's IP address is going to just pop up within the Google Hangout call. While that's not to say that a more industrious computer user couldn't probably figure it out, your average person isn't going to just see your IP address on display. The new peer-to-peer functionality will work with any version of Google Hangouts—iOS, Android, and Web—as soon as Google finishes rolling out the required updates and you've updated your app to the latest version. Of course, the person you're calling will also need to have the latest version of Hangouts for peer-to-peer to work.

Model that is made possible by the use of cryptographic signatures (a mathematical technique to authenticate transactions). When a user wants to send BTC to another user, they sign the transaction with their private key, a 256-character binary code. This signature is then verified by the network to ensure that the Bitcoin transaction is valid.Double spendingDouble spending is an additional problem that is unique to digital currencies. It occurs when a user spends the same digital asset twice, or more specifically when they send the same digital asset to two different recipients. While this may sound like a trivial issue, it can have major consequences for businesses and consumers who use digital or virtual currencies.Bitcoin solves the double spending problem by using a data structure called a blockchain. In a blockchain, a “block” is simply a collection of data that contains information about multiple transactions. Each block is linked to the previous block and secured using cryptography, forming a chain of blocks (hence the name “blockchain”). If someone tries to spend the same bitcoin twice, they will have to create two separate blocks, and thus two different versions of the blockchain. This makes it easy for others to spot the fraud and reject one of the blocks.How was Bitcoin created?In 2008, a research paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" was published under the pseudonym Satoshi Nakamoto. In the paper, Bitcoin was presented as a solution to many of the problems faced by traditional money, with special emphasis given to the double spending problem.The paper sparked a lot of interest among developers who saw potential in Nakamoto's idea, and in 2009, the vision outlined in the nine-page document manifested into the world's first fully decentralized cryptocurrency: Bitcoin. The first cryptocurrency officially launched when its first block was mined.How does Bitcoin work?The Bitcoin network is decentralized, which means there is no centralized authority controlling it. New transactions are verified by network nodes and recorded in a public, decentralized ledger called a blockchain.But what are nodes and how do they verify transactions? For this, we'll need to introduce two more concepts:Proof
