This weird transaction goes back forever and spends to new address and extra 0 output every time. It’s like it’s recording some data in the blockchain. Can anyone explain what’s happening? Cheers.

How to scale transaction broadcasting and fetching


I’m working on a browser-based BTC wallet.

I understand that the original bitcoin core client (bitcoind) is not intended to be used across the network, except for whitelisted IP-addresses. This is due security concerns since a wallet can be safed on the bitcoin node.

However, in my case, the wallet is stored on the client/browser. Transactions are built within the browser wallet, but the browser depends on the node, for fetching transactions, UTXOs and broadcasting the transactions. Hence, no private keys or passwords are sent across the network.

What’s the best way, to do this? Should I setup a full node? Are there any good bitcoin-node-as-a-services? Should I use alternative approches (such as [SPV](https://en.bitcoinwiki.org/wiki/Simplified_Payment_Verification))?

*Ahem* Venmo Charging 1% Transaction Fee For Instant Bank Transfers


If even Venmo can’t make money transfers more efficient, fiat really is screwed!

[https://help.venmo.com/hc/en-us/articles/115015844068-Instant-Transfers-FAQ](https://help.venmo.com/hc/en-us/articles/115015844068-Instant-Transfers-FAQ)

*Instant Transfer is a feature that allows Venmo users to transfer their Venmo balance to their eligible Visa and Mastercard debit card, typically within 30 minutes. A 1% fee (with a minimum fee of $0.25 and a maximum fee of $10) is deducted from the transfer amount for each transfer. The standard bank transfer (typically completed within 1-3 business days) is still available for no fee*
