Bitcoin (BTC) builders have introduced the discharge of v31.0rc4 for testing. As highlighted by Bitcoin Core Challenge on X, this main launch follows v30.2 and comes with binaries and draft notes obtainable for assessment by builders, node operators and testers.
New privateness enhancements by means of Tor and I2P networks
The announcement targets Bitcoin researchers, miners and pockets infrastructure suppliers as a significant change has been launched within the cluster mempool design. For readability, the mempool is sort of a ready room the place transactions sit earlier than miners embrace them in blocks.
On this redesign, there may be enchancment in transaction choice for blocks, price effectivity and the dealing with of advanced transaction packages. Somewhat than impose limits, the brand new system organizes transactions into clusters.
It comes with a default restrict of 64 transactions per cluster and 101 kB measurement. The thought is to assist the node make higher choices when prioritizing transactions by charges. Moreover, the replace permits a person to exchange a pending transaction with a higher-fee model. This can make sure that a substitute improves the mempool’s total price construction.
The Bitcoin node software program v31 additionally has improved privateness options, higher price estimation and efficiency upgrades.
On the privateness entrance, transactions can solely be broadcast by means of Tor or I2P networks. The benefit of this over the earlier model is {that a} person’s IP deal with is hidden, and a number of transactions can not simply be linked collectively. It’s going to enhance privateness for Bitcoin customers operating their very own node.
In the meantime, to assist nodes sync sooner and validate blocks sooner, the default database cache was elevated from 450 MB to 1,024 MB. Nonetheless, that is solely relevant on programs with a minimum of 4 GB RAM.
There are a number of outdated choices that had been eliminated, together with paytxfee, maxorphantx and the outdated tor community label. These cleanups simplify the software program and cut back person errors.

Testing section begins forward of ultimate launch
Total, the Bitcoin node software program v31 is supposed to deal with advanced transaction chains higher and enhance privateness. The node efficiency can be higher as blocks get validated sooner with extra correct price estimation.
The builders are hoping that node operators, miners and infrastructure suppliers will put the brand new model to the take a look at earlier than its closing launch. That is to make sure seamless performance when launched.
In one other improvement, JAN3 CEO Samson Mow has dismissed issues round quantum laptop threats to Bitcoin. Mow emphasised that researchers are already forward of the quantum laptop threats with options to safeguard Bitcoin’s transactions.
