    • How to setup a TOR Proxy Gateway through Denarius DDNS Naming System using the Names subdomains as the beginning of onion addresses. Going to use Ubuntu 20.04 and Snap daemon. First install Denarius snap daemon and sync the wallet, grab chaindata to make this faster. Install tor sudo apt install tor Using this guide to install dnsmasq https://unix.stackexchange.com/a/516808 Install dnsmasq sudo apt install dnsmasq Disable systemd-resolved sudo systemctl disable systemd-resolved.service Remove resolv.conf sudo rm /etc/resolv.conf Now we are going to add the Denarius DDNS and nameservers in. sudo /etc/dnsmasq.d/03-denarius-wildcard.conf add these to the file server=/d/127.0.0.1#5333 server=/dnr/127.0.0.1#5333 server=/denarii/127.0.0.1#5333 server=/king/127.0.0.1#5333 server=/ipfs/127.0.0.1#5333 server=/sys/127.0.0.1#5333 server=/btc/127.0.0.1#5333 server=/bitcoin/127.0.0.1#5333 Edit resolv.conf for our new name servers sudo nano /etc/resolv.conf Add in a clearnet nameserver and the Denarius DDNS localhost nameserver nameserver 127.0.0.1 nameserver 8.8.8.8 Restart dnsmasq sudo systemctl restart dnsmasq Ping a Denarius DDNS site like http://magnets.king ping magnets.king If the ping works this part is working. Setup Tor. sudo nano /etc/tor/torrc Add these lines to the top. HiddenServiceDir /var/lib/tor/ddns/ HiddenServiceVersion 3 HiddenServicePort 80 127.0.0.1:80 Restart Tor service to get our onion address. sudo service tor restart sudo cat /var/lib/tor/ddns/hostname I get 3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid.onion Setup NGINX sudo apt install nginx Edit the default config file because I am lazy sudo nano /etc/nginx/sites-available/default Add this in and adjust the onion address server { listen 127.0.0.1:80; server_name ~^(?<subdomain>.+)\.3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid\.onion$; location / { resolver 127.0.0.1 valid=30s; proxy_pass http://$subdomain; proxy_set_header X-Real-IP $remote_addr; } } Restart nginx. sudo service nginx restart Open up TOR Browser and go to Denarius DDNS names like this http://wiki.d.3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid.onion/ http://stats.d.3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid.onion/ http://satoshi.bitcoin.3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid.onion/ http://magnets.king.3lervphhwefgayia6fvbdokw2avdev3pa5u4h4bjhhonetl3z67uzeid.onion/ You should now have a a Tor Proxy gateway that can see the Denarius names as a wildcard catchall subdomain. Adjust for only sites you run or for clearnet sites you run to give newbies an easy way to check out a decentralized naming system on a blockchain.

    • Hi to everyone out there, since i like the style of Denarius quite much, following and holding coins since a long time and beeing myself as well into software engineering, i'd like to share some ideas that could maybe look good within Denarius. I know that not all ideas might belong diretly into the Developement Section of this forum but since they always include a technological part i think its right place to start. To give a first overview i'll group my ideas here and get into them in the upcoming posts within the next time. Reversed Staking for "lost" coins   To combat a higher deflation and to make staking for the normal users more interesting a protocol change needs to be implemented Coins on adresses that appear to be lost or simply forgotten incur a negative fee after a specific period X so they will slowly move back into the circulating supply SMS-Wallet-Service To make the coins more attractive for a group of people who could really make it a great use case in daily life you would need to make it available for countrys where there is no real payment system available, no banks  Lot of third world countrys dont have smartphones or internet access and rely on a sms style banking service Comes down to integrate a sms wallet to send and receive coins Community Air Drop Major problem with most of the coins available is a big premine or unfair distribution in circulating coins. A fair distribution of wealth is impossible. If either there would be something like a denarius foundation or a community financed airdrop of a significant amount of circulating coins to a broad number of users the Denarius Project would be able to move to a better adoption level An idea for fair distribution could be achieved over the mobile wallet, and the airdrop will only be initiated once the number of registred users pass a certain amount, lets say distrubuting 1.000.000 Coins once at least 100.000 People have registered could make a significant impact Because phone numbers are more difficult to obtain and register then mail wallets or bitcoin/crypto adresses and still maintatin a certain pseudonimity the described wallet service could be an good idea Real World Use Cases With the integration of the new DNS service, there is still a need for runnign services on chain. For this Idea a new sort of nodes running on the network could solve the problem and bring other parties onto the chain 😉 More when the time is right  Homomorphic Encryption To combat censorship and to maintain a free internet its important to enable and work with encrypted data without decrypting it where it is processed. Therefore, alternative keys that are used f.e. homomorphic services and are to be created, burned and organized from within the denarius wallet could solve this issue. Same goes here, more when the time is right For now just a quick summarize, in case you have questions or anything else just feel free to start discussion on here or get into direct contact with me. best regards to the communtiy, MagicManolo
    • How to Revoke Ethereum or Binance Smart Chain Smart Contract Spending Allowances Many people are unaware that when you interact with defi applications/dapps you usually end up allowing the smart contract to have unlimited allowance of spending those tokens on specific smart contract. This is a dangerous practice and is extremely unsafe. This guide will work for both Ethereum and Binance Smart Chain To protect yourself better, simply find the token address of the specific token you want to deny spending of, in this example I will use the token BAKE https://bscscan.com/token/0xE02dF9e3e622DeBdD69fb838bB799E3F168902c5 - BAKE BEP20 Token Contract You want to take that token address and go to the actual Contract Page of the Token: https://bscscan.com/address/0xE02dF9e3e622DeBdD69fb838bB799E3F168902c5#writeContract Once you are on this page under the "Write Contract" option, click the "Connect to Web3" to connect your Metamask wallet to Bscscan/Etherscan. You will then input the address of a smart contract you want to deny/revoke this token spending from, e.g. a LP contract or staking contract, etc. You set the amount to 0 Simply hit "Write" and Metamask should popup asking to complete the transaction. Done. You have now disallowed/set the spending amount to 0 of that token to a specific smart contract. You can rest assured knowing some random smart contract you allowed last summer can't spend your fortune of aped tokens.
