Off-topic / Bitcoin Stash (BSH) Merged Mining Guide for SHA256 Coin Miners

Bitcoin Stash Merged Mining Guide
Overview
Bitcoin Stash is a merge mineable cryptocurrency that utilizes SHA256 for its mining algorithm. This means that it can be merge mined with other SHA256 coins like Bitcoin an Bitcoin Cash. Merge mining is a process where a miner is able to mine multiple cryptocurrencies at the same time. All that is required for a miner is to add 48 bytes of data to the coinbase of the parent block.
We will have a private testnet testing phase beginning at 11/4/18. On 11/4/18, miners will have access to Bitcoin Stash binaries (with only testnet capabilities available). They will be able to merge mine on the testnet by following the below instructions. A sample code implementation is provided in bitcoinstash_mergemining_sample.py.
Instructions
Follow the step belows to merge mine on Bitcoin Stash. Sample code implementation is provided in bitcoinstash_mergemining_sample.py.
1.Use RPC call getnewaddress() to get a new address for Bitcoin Stash (this will only need to be done once)
2.Call RPC command createauxblock() with address obtained from step 1). This will make a Bitcoin Stash block with a coinbase payment to the address.
3.From the JSON output of createauxblock(), use 'auxcoinbasedata' to obtain the data that must be inserted into the script sig of the coinbase in the parent block. To understand how this data is constructed, read the 'Constructing the Auxpow Coinbase Data' section below.
4.Start solving the parent block until you meet the encoded target threshold specified by the 'bits' field in the JSON output of createauxblock().
5.If the parent block meets the target as defined step 4, construct the auxpow header data. Submit the auxpow header data using RPC command submitauxblock() with first argument being 'hash' from output of createauxblock in step 2), the second argument is the hex string of the auxpow data. Instructions on constructing the auxpow data is shown below. If a valid auxpow header data was submitted, the merge mined block will be submitted on the Bitcoin Stash network.
Constructing the Auxpow Header Data
Auxpow header data is extra data attached to the BitcoinStash block header that links the block to the the parent block. It is composed from the below data.
Serialized coinbase transaction +
Hash of the parent block (32 bytes) +
Merkle branches (can be 0x00, if only transaction in block) +
Index in the merkle branch (4 bytes, must always be \x00\x00\x00\x00) +
Chain Merkle branch (4 bytes, can be 0x00, if no other child chain) +
Index in the chain merkle branch (4 bytes, can be \x00\x00\x00\x00 if no other child chain) +
Serialized parent block header
Constructing the Auxpow Coinbase Data
The auxpow coinbase data is data inserted into the parent block's coinbase to link the parent block to the BitcoinStash block. It is composed from the below data.
Merge Mining Header (4 bytes, must always be \xFA\xBE\x6D\x6D ) +
Root hash of Merkle Trie containing child chian (32 bytes, set to hash of Bitcoin Stash block if no other child chain) +
Merkle Trie Size, (4 bytes, set to 1 if no other child chain) +
Nonce, the nonce and the chain id of the child chain determines a pseudo random slot in the chain merkle trie (4 bytes, can be set to anything if no other child chain) +
Parent Chain Id (4 bytes, set to 210 if Bitcoin is the parent block 209 if Bitcoin Cash is parent block)
Stand Alone Mining
Stand alone mining (mining Bitcoin Stash only without using its merge mining capabilities), will also be possible through the standard RPC call getblocktemplate.

Skynavpro™

We are proud to announce today the start of our ICO. Just another ICO? NO! We do have 12,000 registered

pilots, 8,700 APP downloads and a working appliance prototype. Invest in the next phase: global marketing of

sky[nav]pro for manned and unmanned aircraft's (drones), a multi-billion US$ market. We welcome you on board

as part of the in-flight revolution. Investment opportunity:

Skynavpro™ is a planning and navigation software integrated in a specially developed hardware for

communication, collision avoidance and live tracking for general aviation. It is the first product in the

world which successfully combines these extremely useful features in a single and portable box that can be

cost efficiently mass-produced. Our longterm goal is to develop an extensive system-level integrated cockpit

architecture based upon portable devices. The software, consisting of an online planning and navigation

application, is offered free of charge. For additional and premium services (such as live weather data,

collision alerts, worldwide tracking with integrated SOS feature) the specially designed and developed

hardware is required. The hardware will be available in a variety of models on our online shop as well as

through certified partners. Throughout central Europe skynavpro™ is an already well-established brand and

hardware prototypes are already developed. Due to its system level integration concept it can easily fit in

any manned and unmanned aircraft (e.g. drones, UAV’s).
Therefore, Dacher Systems GmbH plans the initiation of an ICO. The proceeds of which will be directed

towards the development of a new blockchain-operated flight-planning and tracking platform as well the

production of the first units for mass market. This will be launched worldwide through several phases. The

platform is unique and has the potential to establish itself as a standard in general and business aviation.

Alternative cryptocurrencies / Launching Ceremony for mit messenger and Boxcorn
« Last post by Aaron on November 29, 2018, 06:03:41 PM »

KMS Global (CEO KJ Kim) will hold a launch ceremony for the International Crypto Exchange ‘Boxcorn’ and ‘mit messenger’ inviting 300 VIP people such as Senator Pacquiao, SAP “Bong”Go, HIV TV Chairman Rey Langit at the Conrad Hotel in Manila, Philippines on December 4th.


Boxcorn is expected to simplify the remittance of foreign workers from Filipinos, which are known to be more than 15 million people. In addition to expanding off-line exchanges and transactions in foreign exchange transactions to deal with casinos, which are comparable to those in Macau, Stargram Coin (SGC) has recently been selected as the key currency.


mit messenger, which means 'together' in German, plans to create a blockchain ecosystem through messenger launches in the Philippines, the world's largest SNS country.


Representative KJ Kim expressed his intention on the launch ceremony, saying, "We will build a growth engine by constructing a structure in which blockchain platforms based on the Philippines-based boxcorn and mit messenger will grow together through mutual growth."


For participating in the launch ceremony of Boxcorn and mit messenger, please visit the homepage below and apply for participation.
