While we build Union, Rootstock's powpeg is still improving.... now becomes cheaper and more scalable...

What does this mean for users? • The set of pegnatories can now grow from 9 to 20, boosting decentralization and paving the way for up to 60 in the future. • Moving your rBTC back to Bitcoin is now 60% cheaper. Another milestone toward a stronger and more accessible Rootstock…

How can we build scalable, optimistic bridges directly on Bitcoin? fairgate.io/publication/29… Existing designs depend on stateful blockchains like Ethereum, but Bitcoin’s UTXO model lacks that flexibility. Enter BATTLE for Bitcoin.


A new week.... more exciting news! One update’s still missing from the newsletter: @ArkLabsHQ launched the Public BETA of Arkade (a Bitcoin L2)

At @btcplusplus Berlin our CTO @SDLerner showcased how @BitVMX - based payment channels could bring constant space for watchtowers, HTLCs with route privacy, without requiring a Bitcoin softfork. Watch the full talks on our YouTube channel 👇 youtu.be/A1aOyzAlVas

BitVMX’s open source journey continues. bitvmx.org/knowledge/bitv… We’re sharing two core components: 🛰️ Operator Comms: direct TLS-based peer channels 🧩 Broker: routing, allowlists, and message flow Discover the details 👇


The only problem we should be addressing now is Bitcoin mining centralization. If we have a few pools with >51% of the hashrate, then ALL Bitcoin fraud-proof based protocols (BitVM, Ark, Lightning) can be broken using bribing contracts to censor txs. OP_RETURN? a distraction

What makes BitVMX Protocol Builder a key piece in Bitcoin protocol design? It brings structure and determinism to Bitcoin protocol engineering, mapping every possible execution as a DAG of pre-signed txs. bitvmx.org/knowledge/bitv… Read more in Diego's latest article here 👇
