Update 2025: Why I am running Bitcoin Knots
I use Bitcoin Knots because its enhanced filtering options give me more control over which transactions my node accepts and relays, helping protect the network from spam and unwanted data without compromising consensus rules. This aligns with a philosophy of maximizing decentralization and user sovereignty by avoiding overly restrictive policies imposed by Core.
Summary: Bitcoin Knots vs. Bitcoin Core
| Aspect | Bitcoin Core | Bitcoin Knots |
|---|---|---|
| Network Share (2025) | ~99.5% | ~4–13% (growing) |
| Development | Community-led, multiple maintainers | Single maintainer (Luke Dashjr) |
| Stability | Highly tested, very stable | Less tested, slightly higher risk |
| Customization | Conservative, limited user options | More flexible, advanced mempool filters (e.g., spam filtering) |
| Spam Filtering | Limited | Advanced (e.g., datacarrier=0 option) |
| Philosophy | Stability and broad compatibility | User sovereignty and policy pluralism |
Using Bitcoin Knots is a choice for those who want more control over mempool policies and spam filtering, valuing customization and resistance to what some see as Core’s overly restrictive transaction policies.
Bitcoin Core
You can find old version for older PC/MACs easily.
Minimum Hardware requirements:
4GB RAM (trust me I tried to run node in 2011 MacBook Air with 2GB RAM)
Only have 2GB RAM in your old hardware? Install: Linux Mint & Parmanode.com
1TB of SSD, NVMe even better) for full Bitcoin Node (HDD not recommended)
Bitcoin full blockchain size is currently at 560+ GB, growing 100-150 GB a year.
For pruned node: 300MB of SSD minimum (not recommended).
