kandi X-RAY | cpuminer-xzc Summary

cpuminer-xzc is a C library typically used in Blockchain applications. cpuminer-xzc has no bugs, it has no vulnerabilities and it has low support. However cpuminer-xzc has a Non-SPDX License. You can download it from GitHub.

!!! THIS IS A HACKED VERSION TO SUPPORT ZCOIN (XZC)'s Lyra2Z algo ! ONLY USE WITH ZCOIN AFTER BLOCK 20500 !!. Use -a lyra2z for XZC mining on pools like on or solomining. This contains following optimizations by optiminer: * Some unnecessary computations and memory accesses removed. * Code for AVX2 can be enabled by compiling with "-mavx2": $ CFLAGS="-O2 -mavx2" ./configure && make clean && make * Memory prefetching can be enabled by compiling with "-mavx2": $ CFLAGS="-O2 -DROW_PREFETCH" ./configure && make clean && make. The different flags can also be combined. If you are building for your local CPU, use "-march=native" as well. The hash algorithm is memory bandwith bound, therefore AVX2 / prefetching will not have a big impact on performance. This is a multi-threaded CPU miner, fork of [pooler] //github.com/pooler)'s cpuminer (see AUTHORS for list of contributors).

QUESTION

Why Metamask if web3.js can interact directly with ganache?

Asked 2022-Mar-30 at 17:55

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 09:11

If 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).

How to get all the NFTs of particular smart contract

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 15:03

The 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).

The 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.

QUESTION

Should I use the elrond devnet instead of the testnet for development?

Asked 2022-Mar-08 at 09:03

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?

utils.ts

...

ANSWER

Answered 2021-Aug-24 at 12:56

The 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.

ANSWER

Answered 2021-Nov-28 at 10:14

it 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

Weth is different from other token, you're not able to use swapTokensForTokens. We must use the swapEthForTokens function instead, and you have to declare the data option separately.

so in your case we need to do:

ARM:
No runtime CPU detection. The miner can take advantage of some instructions specific to ARMv5E and later processors, but the decision whether to use them is made at compile time, based on compiler-defined macros.
To use NEON instructions, add "-mfpu=neon" to CFLAGS.
x86:
The miner checks for SSE2 instructions support at runtime, and uses them if they are available.
x86-64:
The miner can take advantage of AVX, AVX2 and XOP instructions, but only if both the CPU and the operating system support them.
Linux supports AVX starting from kernel version 2.6.30.
FreeBSD supports AVX starting with 9.1-RELEASE.
Mac OS X added AVX support in the 10.6.8 update.
Windows supports AVX starting from Windows 7 SP1 and Windows Server 2008 R2 SP1.
The configure script outputs a warning if the assembler doesn’t support some instruction sets. In that case, the miner can still be built, but unavailable optimizations are left off.
