kandi X-RAY | polycash Summary
PolyCash is an open source P2P blockchain protocol & app that makes it easy to launch your own digital currencies and crypto assets. PolyCash is a colored coins implementation & is a virtualization layer for the blockchain. It can be used to create currencies on top of bitcoin, litecoin or any other blockchain based on the Bitcoin source code. The PolyCash web app runs on PHP and MySQL and is easy to install and configure. PolyCash is designed for stablecoins which are backed by tangible assets such as dollars, stocks or intellectual property. PolyCash was built for P2P prediction markets, and betting currencies are the primary application of this protocol. But PolyCash is also great for launching crypto assets which have nothing to do with betting. This app includes a blockchain explorer which is useful for viewing blockchain data. PolyCash loads blockchains into a relational database making it easy to run fast queries about blockchain data. Design your new currency by choosing a blockchain to run on, a name for your coins and an initial supply. Then create your genesis transaction and import the new coins into your wallet. Next decentralize your currency by installing it on a bunch of different nodes and distributing the coins to any initial investors and stakeholders. You can manage the list of betting events associated with your currency by uploading a spreadsheet or by integrating an API data source. Depending on the topology of your network, any changes that you make to the betting events for your currency may automatically propagate or may require the approval of the node operators running your currency. Install bitcoin if you want to allow your players to buy in and cash out to BTC. PolyCash requires all blockchains to be installed as full nodes. Each installed blockchain is synced to MySQL in real time requiring significant RAM, disk space, CPU and IO. To efficiently operate a node running bitcoin, you may need to spend around $100 / month for a dedicated server.

QUESTION
I am new to blockchain app development, I saw a project where ganache accounts are imported into Metamask, then web3.js is used to access and print those accounts and balances on Frontend (user interface).
If web3.js can directly access ganache blockchain accounts and balances, why do we need Metamask in between?
...ANSWER
Answered 2022-Feb-08 at 09:11If web3.js can directly acccess ganache blockchain accounts and balances, why we need metamask in between?
In this case, you don't need MetaMask to sign the transaction, as the node (Ganache) holds your private key.
But in a public environment (testnets and mainnet), the node doesn't hold your private key, so you'd need to sign the transaction using MetaMask (or any other tool that holds the private key).

I tried https://docs.opensea.io/reference opensea.io docs to fetch data. However, I think there are 2 APIs.
...ANSWER
Answered 2021-Aug-04 at 15:03The assets endpoint (docs) has the asset_contract_address filter that allows you to filter by a contract address. Which will effectively allow you to paginate through all NFTs of the contract (that Opensea knows of).

I have been trying to interact with a contract on the AVAX chain using web3js and it keeps throwing the error, "TypeError: Cannot read properties of undefined (reading 'send')". I cannot figure out why this is happening, as it should be a valid statement. If anyone can help that would be awesome.

Answered 2022-Mar-19 at 17:10The ABI needs to contain just the function and event definitions that are stored in your result property. Without the wrapper object containing status and other properties.
So in your case
QUESTION
I've been using the testnet lately and I encounter issues: they reset it very often and the service is down for multiple hours and sometimes have bugs.
Should I use the devnet? From what I've understood it's more stable and they reset it less often?
I have a backend in js that uses the elrond-sdk-erdjs and I'm confused because there is no function that initializes the https://devnet-gateway.elrond.com only the testnet. Is there a reason?
...ANSWER
Answered 2021-Aug-24 at 12:56The testnet is pretty volatile and it is reset very often (maybe weekly), without any warnings. Elrond recommends developers to use the devnet, it is reset maybe once every 3-4 months, so it's more stable.

Hey guys I am trying to deploy my project on the rinkeby chain using infura, but I am getting a ValueError Here is my trackback:
...ANSWER
Answered 2021-Nov-28 at 10:14it appears your env variables are not set correctly, and it looks like in this case it's your WEB3_INFURA_PROJECT_ID.
You can fix it by setting the variable in your .env file and adding dotenv: .env to your brownie-config.yaml.
brownie-config.yaml:
dotenv: .env .env:
export WEB3_INFURA_PROJECT_ID=YOUR_PROJECT_ID_HERE Remember to save these files.
Additionally, you should be on at least brownie version v1.14.6. You can find out what version you're on with:
brownie --version

Install polycash
The user account you set up when installing has special permissions. Use this account to import any game definitions for crypto assets that you want to run on your node. Any time you update PolyCash from github, make sure to visit the install page and any new database migrations will automatically be applied. Use the install page to enter the RPC parameters for any blockchains that you want to use. Install and start your blockchains as full nodes before entering the RPC parameters. To install full nodes, make sure to set txindex=1 in bitcoin.conf, litecoin.conf etc. After entering blockchain RPC parameters, use the "reset & synchronize" link on the install page to quickly insert initial empty blocks. You need to set the right value for "first required block" for any blockchains that you install. You should set the first required block for each blockchain at least as early as the lowest starting block for any games that you plan to install on that blockchain. You should try to avoid ever changing the first required block to a lower value because this will cause the entire blockchain to re-sync with PolyCash which can take hours or days.
