Pull request description:

  This is a simple PR that updates the block policy estimator’s `MIN_BUCKET_FEERATE` constant to be 100, which is identical to the policy `DEFAULT_MIN_RELAY_TX_FEE`.

  This change enables the block policy fee rate estimator to return sub-1 sat/vB fee rate estimates.

  The change is correct because the estimator creates buckets of fee rates from
  `MIN_BUCKET_FEERATE`,
  `MIN_BUCKET_FEERATE` + `FEE_SPACING`,
  `MIN_BUCKET_FEERATE` + `2 * FEE_SPACING`,
  … up to `MAX_BUCKET_FEERATE`.

  This means it will record sub-1 sat/vB fee rates in the buckets and may return them as a fee rate estimate when that bucket is the lowest one with sufficient transactions for a given target.

  ---

  While touching this part of the fee estimator code, this PR got rid of the dummy value persisted in the file

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)
  • bin/bitcoin (wrapper command)

The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
