Our team will be be attending and speaking at this yearβs edition of @bitcoinconfams π³π±.
Bitcoin Amsterdam brings together developers, entrepreneurs, researchers, investors, and community builders from across the global bitcoin ecosystem to exchange ideas, explore emerging developments, and discuss the future of bitcoin.
Tomorrow, @ihate1999 and @sadeeq_ismaela will take the stage alongside Rob Netzke for a discussion on getting started in Bitcoin open-source development.
Later in the day, @ihate1999 will take the Treasury Stage to explore the priorities, principles, and trade-offs shaping bitcoinβs future, from individual sovereignty to mainstream adoption, and whether the community needs a shared vision or room for disagreement.
Weβre looking forward to meeting fellow builders and members of the wider Bitcoin community, exchanging ideas, and exploring opportunities to build together.
See you there! β at Amsterdam, The Netherlands

On 6 November Iβll be at Bitcoin Amsterdam on the Proof of Work Stage moderating:
Who Controls the Mining Stack?
Iβll be joined by:
- Duncan Coombe - The Solo Mining Co
- Abubakar Sadiq Ismail - 2140.dev
- BitMaker - Bitronics
Weβll be looking at where real control sits in Bitcoin mining today.
The discussion will cover how open source hardware and tools can shift that balance, the practical difference home miners can make against large industrial operations and what would need to change for independent mining to become a counter to centralisation.

Did you know you can build a stick visualization of your mempool clusters and fee estimation using the getmempooldiagram RPC?
Did you know that if you also include PR #34075 you can see how accurate the fee estimation for previous blocks was?
