How to run Bitcoin Core as a production RPC Node?

I'm planning to build a wallet service with the following features:

  • Query balance
  • Query transaction history
  • Send transactions

I want to self-host a Bitcoin Core Node as my RPC Node. Since this is my first time running a Core Node in a production environment, I'd like to ask:

1.High Availability — Should I run multiple nodes for failover? What's the recommended setup?

2.Monitoring & Sync — How do I monitor whether my node is properly synced? Are there any recommended tools or metrics? Also, is block lag completely unacceptable for a wallet service, or is there a tolerable range?

3.General best practices — What does the community recommend for running a Bitcoin Core RPC Node in production?

Any advice or recommended tools would be appreciated. Thanks!

According to a post shared on X by Keith Grossman, president of crypto payments firm MoonPay, finance is heading toward an onchain future that could unfold over several years.

BlackRock has already launched tokenized funds, while Franklin Templeton is running tokenized money market funds on public blockchains. Those actions suggest that tokenization is no longer confined to pilot labs or internal trials. It is being used with real assets and real clients. Bank of Ameri...

Bitcoin Mining Could Be Strengthening The Ruble, Russian Central Bank Says

Image
Bitcoin mining may be providing incremental support to the Russian ruble, Central Bank Governor Elvira Nabiullina said, while cautioning that the effect is difficult to measure because much of the sector still operates in a legal and reporting gray zone. Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...
