The recent release of Bitcoin Core 29.1 has introduced a major update, significantly reducing the default minimum relay fee for transactions. This change is a milestone that can impact the cost-effectiveness of cryptocurrency transactions across the Bitcoin network, making them much cheaper than ever before.
What’s New in Bitcoin Core 29.1?
As of September 4, Bitcoin Core 29.1 officially updated its default minimum relay fee to 0.1 satoshis per virtual byte (sat/vB), a sharp 90% drop from the previous 1 sat/vB. This adjustment allows users to enjoy more economically efficient transactions without compromising the network’s security against Denial of Service (DoS) attacks.
Relay fees are vital because they dictate which transactions nodes relay across the network. Every Bitcoin node operator can set their own relay fee limits, but the default values are widely accepted by most operators. By lowering the minimum value, Bitcoin Core developers aim to streamline transactions without causing network disruptions.
Why Was This Change Necessary?
The decision to lower the relay fee was based on changes in Bitcoin’s exchange value over the last decade. This shift allows for adjustments in transaction costs while maintaining a balance between affordability and network protection. Bitcoin Core explains that the minimum relay fee acts as a safeguard against spam and DoS attacks. However, with Bitcoin’s price having grown significantly, reducing this fee no longer poses a significant threat to security.
Additionally, issues arose when transactions below 1 sat/vB were being successfully mined but failed to propagate quickly across nodes that rejected lower fees. This inconsistency prompted a necessity to align defaults with real-world practices.
The Current State of the Bitcoin Network
According to BitRef data, approximately 72.5% of Bitcoin nodes run Bitcoin Core software. Of these, Bitcoin Core 29 is the most widely adopted, but only 571 nodes currently use the latest 29.1 version, where the new fee structure applies.
On the other hand, Bitcoin Knots, which is a fork of Bitcoin Core, represents around 27.25% of the network. While it is based on Bitcoin Core 29.1, it does not incorporate the new default values. Instead, Bitcoin Knots allows users to configure transaction policies more flexibly via its graphical user interface.
What This Means for You
This update is a major step toward making Bitcoin transactions more affordable and accessible. If you’re a frequent cryptocurrency user or investor, this could drastically reduce your transaction costs, especially when moving smaller amounts.
Pro tip: Use tools like Mempool.Space to calculate and optimize your transaction fees based on real-time network conditions. Their recent advice to users is to avoid overpaying for blockchain space as “0.1 sat/vB is the new standard.”
Enhance Your Crypto Experience
