Merged mining, chain locks, zk based data availability and sidechains.
For the 9th episode of our Bitcoin and Beyond presentation series, we had the pleasure to chat with @realSidhuJag of @RolluxL2 to about scaling Bitcoin.
We discuss the extension of Bitcoin’s security through merge mining, chain locks for finality, long-range attacks on consensus, liquidity bridging, and the key differences in optimistic and zk-rollups in Bitcoin.
Jag has a very unique perspective on scaling Bitcoin and is very ethos aligned with the core Bitcoin community.
Watch today’s video to uncover what’s really happening behind the scenes in Bitcoin scaling:

03:30 The Bitcoin Superchain
04:39 Rollux Stack
22:46 Layer 0 for Bitcoin
27:10 Why Rollux Needs Syscoin
37:36 Blockchain as Islands
59:48 Conclusions on Scaling Bitcoin

We have finished the @RolluxL2 whitepaper. Look for it soon! As it pertains to @syscoin for settlement and using BitcoinDA and @Bitcoin with merged-mining + aggregated BLS finality (from sentry nodes creating chainlocks). It is the first solution to offer light-client security where 2 distinct sets of distributed permissionless consensus participants must collude to override the honest chain. This is big because it relates to not only zkDA (selling DA services across chains) but also scaling Bitcoin through something like BitVM.
Let's analyze the game theory and how this breakthrough is relevant:
1) Use Ethereum as a sidechain to Bitcoin and use a proof-of-burn on Ethereum within BitVM to unlock deposits.
2) Use Syscoin as a sidechain to Bitcoin (using @RolluxL2 as the execution layer or L2 to scale Bitcoin use-cases). Proof-of-burn on Syscoin within BitVM to unlock deposits.
In both cases you will likely use a ZK proof of the chain and inclusion of the burn transaction. In case of Ethereum or any other PoS chain you will overtake the validators and steal the funds. There is a high cost to do this but if enough Bitcoin is bridged and its of sufficient value then it will happen. The assumption here is purely crypto-economics.
In the case of Syscoin since it is merge-mined with Bitcoin even if you overtake the validators by buying a supermajority of them and running them to create a fake chain, you still need to coordinate with Bitcoin miners to mine at the Bitcoin difficulty to create a fake light-client chain, rather than just attest blocks via the validators like any other PoS chain. The coordination imposes a game theoretical assumption as well as a crypto-economic one for security. This would be the first in the industry.
How this solution applies to cross-chaining messages such as selling DA services from BitcoinDA to other chains so they can run rollups at scale using @Bitcoin security: An EVM ZK light client will allow anyone to post proofs along with finality attestations (chainlocks) to lock the chain every 5 blocks. An attacking miner will have to start his attack over again after 5 blocks unless he coordinates with ALL of the validators.
In BitVM a ZK proof of burn is provided to unlock the BTC on @Bitcoin to withdraw. Users which recognize that a super majority of nodes have colluded and recently have been purchased off the market can "front-run" the attacker by exiting the bridge before an attack can happen. By having a dual security layer and multiple groups of participants having to participate we enable this detect->front-run capability that doesn't exist elsewhere.
The detect->front-run is a side-effect of the dual set participant collusion, and the other major understanding is that an established sidechain enables "detection" because coins have been distributed over PoW over many years whereas new sidechains with VC allocations may not be fairly distributed and run the risk of secret accumulation.
So to recap: we present a new way to solve Bitcoin scaling + cross-chain messaging via EVM->EVM to provide services such as zkDA.
The main attributes to prevent attacks are:
1) detect->front-run an attack to enable a Nash Equilibrium for honest behaviour over dishonest.
2) Established sidechain to maximize the chance of detection through PoW distribution via AuxPoW over 10 years.
