[ANN][GRS] Groestlcoin | 1st to activate Segwit & Taproot

[gruve_p]

grsd is an alternative full node groestlcoin implementation written in Go (golang).

If you want an alternative full node wallet and are an advanced user, then grsd is the right choice for you.
It also properly relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block.
It ensures all individual transactions admitted to the pool follow the rules required by the block chain and also includes more strict checks which filter transactions based on miner requirements ("standard" transactions).

Nice trading on CoinEx lately.

I am studying GRS addresses -- sigh

And we are back on Flypme:

[jackielove4u]

I am studying GRS addresses -- sigh

What seems to be the issue with addresses?

[IMZ Noo Account]

'What seems to be the issue with addresses?'

The issue with the addresses is that they are smarter than I am. And a couple of times I have gotten tangled up because an exchange didn't recognise an address I wanted to use for a withdrawal.

Meanwhile, the Telegram thread is busy

[IMZ Noo Account]

GRS<>BLK trades on AtomicDEX.

Just learning. Just experimenting.

[IMZ Noo Account]

CoinEx remains good for small regular trades.


EDIT 19/3: Actually, CoinEx has been great in recent weeks. I am teaching a French backpacker how to trade. He has background in NFT development, but never traded 'steadily.'

[IMZ Noo Account]

GRS is now listed on Frei Exchange

[IMZ Noo Account]

Happy birthday, Groestlcoin.

Great trading on Coinex in recent days, and someone got GRS at 1020 on Frei -- but now that I know of this listing on Frei, I will be closing the buy-sell spread.


"March 21 (Reuters) - First Republic Bank's (FRC.N) efforts to secure a capital infusion continued without success on Tuesday, as the troubled regional lender started to plan for the possibility it may need to downsize or get a government backstop."

It's fun trying to figure out if the banking drama has stopped (which tells us about Bitcoin price, and so GRS's . . . ).

Sparrow-GRS is a modern desktop Groestlcoin wallet application supporting most hardware wallets and built on common standards such as PSBT, with an emphasis on transparency and usability.

Sparrow-GRS does not hide information from you - on the contrary it attempts to provide as much detail as possible about your transactions and UTXOs, but in a way that is manageable and usable.
However, Sparrow-GRS is also unique in that it contains a fully featured transaction editor that also functions as a blockchain explorer. This feature not only allows editing of all of a transaction’s fields, also easy inspection of the transaction bytes before broadcasting.

GRSPay: a free and open-source cryptocurrency payment processor which allows you to receive payments in Groestlcoin with no fees, transaction cost or a middleman.

GRSPay is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your xpubkey or zpubkey.

GRSPay Testnet: a free and open-source cryptocurrency payment processor which allows you to receive payments in Groestlcoin Testnet with no fees, transaction cost or a middleman.

GRSPay Testnet is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay Testnet go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your tpubkey or vpubkey.

GRSPay Testnet is available at https://testnet.grspay.com/
