  1. So I decided to start building an open source hardware wallet....specifically for Denarius (D) I decided upon the ESP32 platform chip due to its powerful feature set enabling the use of cryptographic functions and cheap cost. We have options of Wifi and Bluetooth if needed, though the focus will be around not enabling these on the board. The code is very basic as this is my first time with playing with MCUs and development micro controller boards. Everything will be released in due time as well as this post updated, this thread will serve as a historical and discussion venue. Some early prototyping with a breadboard + ESP32 Dev Board + 128x32 OLED display Some serial console output of some transaction signing attempts on chip
  2. So not a lot of information out there, but if you want to convert a Bitcoin or Denarius or any standard crypto typically, you take the block hex to a block hash (typically used for block explorers and things) you just do the following: changeEndianness(SHA256(SHA256(BLOCKHEX))) So basically visually in text it would be: BLOCKHEX => Hashed to SHA256 => Hashed to SHA256 => Swap Endianness = Block Hash You are just hashing the hex twice and then swapping the endianness to obtain the hash of the block.
  3. Denarius's genesis block was created 3 years ago today (6/14/2017). Happy 3 years old Denarius and thank you to everyone for your support of D over the years! Register here on BlockForums.org and make a post in this thread saying how you found Denarius (D) with your Denarius address and receive 1.0 D and 100 BF$!
  4. Been wondering how to make use of the electrumx server, but in bash. First I needed to connect to the electrumx server. #!/bin/bash echo "get block header" (echo '{"method" : "blockchain.block.header", "params": ["1"], "id": "msg_id"}'; sleep 1) | ncat --ssl electrumx1.denarius.pro 50002 This outputs. block header {"jsonrpc": "2.0", "result": "06000000cd8f82c4c28201fd89def0dba541d66432bff9c1bb16fc1c6201dabb5d0d0000e4abd1522f390c5a2b83add7c8d29b875e1e0691dc43267f0406e9ddfea329c76ab74159ffff0f1e000d8425", "id": "msg_id"} So now to get a balance. The thing with electrumx server is that you need a scripthash to call any address functions. But I don't have that. All I have is a bash terminal and a Denarius address. So what do I do? Line by line dissect how people create an address and then work backwards to the scripthash. I need this image, but down to up. source: https://learnmeabitcoin.com/guide/p2pkh This is not so easy as I can't find anyone doing this backwards in bash. But I found lots of posts how to go forwards. Here is how to get it before converting to big endian. #!/bin/bash . denarius.sh #DUP HASH160 begin="76A914" echo $begin #EQUALVERIFY CHECKSIG end="88AC" echo $end echo "decodeBase58" decoded="$(decodeBase58 DCMRvR6MUppPgP8vrMKuni4FL5de8SjicG)" echo "Remove 00 bytes" echo ${decoded#??} removefront=$(echo "${decoded#??}") echo $removefront echo "Remove checksum" removeback=$(echo "${removefront%????????}") echo "95 characters base58" echo $removeback echo "now what?" echo $begin$removeback$end echo "convert to scripthash" echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1 scripthash=$(echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1) echo $scripthash Will also need grondilu bitcoin-bash-tools. https://github.com/grondilu/bitcoin-bash-tools Get the bitcoin.sh and throw that into the same directory you are going to test this out in, for obvious reasons I renamed bitcoin.sh to denarius.sh. First I am assuming a standard P2PKH address with OP_DUP OP_HASH160 hashedpublickey OP_EQUALVERIFY OP_CHECKSIG #DUP HASH160 begin="76A914" echo $begin #EQUALVERIFY CHECKSIG end="88AC" echo $end Then decodeBase58 of our Denarius address, works on bitcoin obviously. echo "decodeBase58" decoded="$(decodeBase58 DCMRvR6MUppPgP8vrMKuni4FL5de8SjicG)" Then remove 00 bytes from the front of this. The #?? removes 2 characters from the left of a string. echo "Remove 00 bytes" echo ${decoded#??} removefront=$(echo "${decoded#??}") echo $removefront Now remove the checksum. The %???????? removes 8 characters from the right of the string. echo "Remove checksum" removeback=$(echo "${removefront%????????}") echo "95 characters base58" echo $removeback Now what? How to convert to scripthash? We can echo the the uncompressed public key, kind of. echo "now what?" echo $begin$removeback$end echo "convert to scripthash" sha256 this in proper format, using xxd and then sha256 that. echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1 scripthash=$(echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1) echo $scripthash At the end from that address I get. 3735fe8239322122222f8a8f42d9b6545bc517e2086116e57953fdc9cc7f6115 For now I have a separate function I found to convert to big endian, since electrumx server wants it this way. source: https://electrumx.readthedocs.io/en/latest/protocol-basics.html#script-hashes #!/bin/bash #echo 6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b | ./bigendian.sh #8b01df4e368ea28f8dc0423bcf7a4923e3a12d307c875e47a0cfbf90b5c39161 # check stdin if [ -t 0 ]; then exit; fi v=`cat /dev/stdin` i=${#v} while [ $i -gt 0 ] do i=$[$i-2] echo -n ${v:$i:2} done echo I run this like echo 3735fe8239322122222f8a8f42d9b6545bc517e2086116e57953fdc9cc7f6115 | ./bigendian.sh and get the scripthash electrumx server wants 15617fccc9fd5379e5166108e217c55b54b6d9428f8a2f222221323982fe3537 Like bash magic we can use that scripthash to talk to the electrumx server to get a balance. #!/bin/bash echo "get balance" (echo '{"method" : "blockchain.scripthash.get_balance", "params": ["15617fccc9fd5379e5166108e217c55b54b6d9428f8a2f222221323982fe3537"], "id": "msg_id"}'; sleep 1) | ncat --ssl electrumx1.denarius.pro 50002 And we get the balance. get balance {"jsonrpc": "2.0", "result": {"confirmed": 125740854, "unconfirmed": 0}, "id": "msg_id"} And a large step forward in creating a basic terminal wallet for any device that can use bash, ncat and has port 50002 open.
  5. PR is in the works to make Denarius and Beam Atomic swaps possible in the Beam wallet. You can start building it to test the atomic swaps via electrum and or the native D wallet. You only will need the Beam wallet though if using electrum. Beam building guide coming soon that adds onto their documentation and new atomic swap guides. https://github.com/BeamMW/beam/pull/1303
  6. Buying 100m OSRS 2007 for $0.50 per mill. Payment in D or BTC
  7. What is the best mining OS you recommend? I personally like HiveOS - https://hiveos.farm
  8. How to Install Snap and Denarius (D) on any Chromebook (ChromeOS) Guide by Carsen Klock First you need to install/enable Linux (Beta) aka Crostini within your ChromeOS Settings. You will be running the following commands in the default Linux (Beta) terminal within ChromeOS to get a full working install of https://snapcraft.io (Snap/Snapd) on ChromeOS with Denarius installed via Snap. Update and Upgrade your Linux (Beta) aka. Debian 9 Stretch by default as of this guides writing: sudo apt update && sudo apt upgrade Now you need to install some dependencies and tools that we will be using: sudo apt install git wget curl build-essential automake libtool autoconf pkg-config udev fuse snap snapd --------------------------------------------------------------------------------------------- Now you will need to install libsquashfuse0 and squashfuse, you can manually compile these and link them, but for ease of use, you can just install their respective .deb packages for your ChromeOS Architecture, Snap will be installed at this point, but it will not successfully mount and install any Snaps until you have libsquashfuse0 and squashfuse packages installed and linked. ARM64 Arch Only: wget http://ftp.us.debian.org/debian/pool/main/s/squashfuse/libsquashfuse0_0.1.103-1_arm64.deb AMD64 Arch Only: wget http://ftp.us.debian.org/debian/pool/main/s/squashfuse/libsquashfuse0_0.1.103-1_amd64.deb Now after downloading the proper libsquashfuse0 from one of the commands above, you want to install it with dpkg, after the -i flag (install) enter in the name of the file with the correct architecture you downloaded for your device: (ARM64 is used in the example) sudo dpkg -i libsquashfuse0_0.1.103-1_arm64.deb --------------------------------------------------------------------------------------------- Now you will want to do the same thing with the squashfuse package as libsquashfuse0 ARM64 Arch Only: wget http://ftp.us.debian.org/debian/pool/main/s/squashfuse/squashfuse_0.1.103-1_arm64.deb AMD64 Arch Only: wget http://ftp.us.debian.org/debian/pool/main/s/squashfuse/squashfuse_0.1.103-1_amd64.deb Now after downloading, the step is the same as above, run dpkg -i to install the *.deb package (ARM64 is in the example below): sudo dpkg -i squashfuse_0.1.103-1_arm64.deb If successfully done correctly, you will now have a working Snap install on ChromeOS! --------------------------------------------------------------------------------------------- Now it is time to install and run your first Snap! sudo snap install denarius It should now install without fail if you followed the commands above and used the proper architectures for your Chromebook, Now to run Denarius on your Chromebook, simply run the command: denarius.daemon You can also install the GUI Snap Store with the snap command: sudo snap install snap-store GUI support and guide will be coming soon
