a fast & nimble spv server that provides Blockchain data to your applications, webapps and SPV wallets

Fulcrum is an open-source implementation of an Electrum server (ElectrumX) completely written in C++.
Fulcrum offers similar functionality to ElectrumX and Electrs, allowing users to connect and interact with the bitcoin network through the Electrum client, so is a complementary software to your bitcoin wallet as its main purpose is to fetch bitcoin addresses, transactions, balances, UTXOs. This cannot be done by Bitcoin Core quickly and efficiently. In fact any wallet that shows your balance, and allows you to send and receive money is a client to software like Fulcrum.

Why host it?

  • Privacy: By running your own server, you have full control over your transaction data and privacy. Public servers may log or monitor your transactions, potentially compromising your privacy and anonymity. Running your own server ensures that your transaction history remains confidential.
  • Security: When you run your own server, you have complete control over its security configuration. You can implement stringent security measures, such as firewalls, encryption, and access controls, to protect your server from unauthorized access or potential attacks. This provides an additional layer of security for your Bitcoin transactions.
  • Decentralization: By running your own server, you contribute to the decentralization of the Bitcoin network. Public servers are often centralized, with a few entities controlling a significant portion of the network's infrastructure. Running your own server helps distribute the network's computational power and supports the overall resilience and security of the Bitcoin ecosystem.
  • Connect

  • tcp: fulcrum.frznode.com:50001
  • ssl: fulcrum.frznode.com:50002 (with trusted certificate)

    Later we will explain with pictures how to connect a wallet to the server
