Previous to the Ethereum ICO of 2014, most early Bitcoiners have been open to the thought of novel blockchain applied sciences. Even Satoshi Nakamoto, method again in 2010, took it with no consideration that an altcoin, BitDNS, wouldn’t solely exist however would merge mine with Bitcoin’s hash price.
Throughout its early years, Bitcoiners anticipated that the majority public blockchain features might combine into the Bitcoin community in a roundabout way.
The neighborhood was tech-savvy and its cypherpunks, cryptographers, and pc builders might simply spot flaws in altcoins like the primary Proof-of-Stake (PoS) altcoin, NXT. Doubtful initiatives have been rapidly dismissed as irrelevant frivolities.
By 2015, Ethereum had raised some $18 million, promising enticing returns to buyers who contributed BTC. Within the words of Vitalik Buterin on March 6, 2014: “What we’re hoping is one thing like what occurred with Mastercoin so… the worth of Ether goes up by 5 [times].”
Many Bitcoiners like now-deceased billionaire Mircea Popescu lamented the get-rich-quick framing of altcoin promoters like Buterin. Some started believing that solely Bitcoin mattered and Popescu started ridiculing all altcoins with spiritual fervor, fostering a Bitcoin subculture of toxicity.
Nonetheless, Ethereum survived and its value ultimately far exceeded any of its founders’ authentic forecasts. Nearly nobody misplaced cash investing in ETH.
By 2016, with Ethereum rallying, the tradition of Bitcoin maximalism remained subdued. Certainly, it wasn’t till 2017 and the ICO bonanza {that a} sizable inhabitants of Bitcoiners started associating with maximalism.
Based on a recounting by Jameson Lopp, “Using the phrase ‘maximalist’ actually got here again into play through the scaling wars and 2017 ICO hype cycle. Plainly using ‘poisonous maximalism’ as a descriptor actually picked up mid-2018.”

Quickly sufficient, maximalists changed the imaginative and prescient of Bitcoin turning into the bottom blockchain for myriad, different blockchains with a more moderen, far narrower mission: digital gold. Certainly, Digital Gold is the title of a guide by certainly one of Bitcoin’s most definitive historians, Nathaniel Popper.
Because the tempo of Bitcoin software program upgrades slowed through the years and decision-making politicized, bold builders started constructing on non-Bitcoin blockchains.
Drivechain: New blockchains funded with BTC and secured by Bitcoin hash energy
Taking the above as context, we will now envision the world during which LayerTwo Labs founder Paul Sztorc initially proposed Drivechain to the Bitcoin neighborhood.
In 2014, virtually no Bitcoiner would have thought of themselves a maximalist. Paul Sztorc was one such Bitcoiner. He purchased his first bitcoin in 2011 and has actively contributed since 2014.
Subsequently, he formally proposed Bitcoin Enchancment Proposals (BIPs) 300 and 301, bundling them collectively below the identify Drivechain. He steered Bitcoin reclaim its expansive energy for platforming, mining, denominating, and securing different blockchains.
Sztorc noticed that many Bitcoiners have been concerned about altcoins and moderately than denounce and mock them, Drivechain would enable them to work on their code utilizing Bitcoin’s community and the BTC asset.
Particularly, Sztorc envisioned a community of side-blockchains that merge mine with Bitcoin’s mining community and use BTC as their base asset. In essence, sidechains are different blockchains — full with their very own altcoins and market-determined values — that use BTC as their funding mechanism and Bitcoin mining for his or her safety.
Non-custodial, peer-to-peer, two-way BTC peg
Proper now, most Bitcoin sidechains like Liquid and Rootstock (RSK) are federated. Most have a few dozen events who’re de facto custodians of the sidechain’s BTC collateral.
Not like federated sidechains, Drivechain retains most of Bitcoin’s decentralized, peer-to-peer, and permissionless options. Sztorc resisted the thought of introducing a federation as a result of it depends on trusted third events to carry belongings.
The essence of Drivechain is extra peer-to-peer. No federation controls the keys to the sidechain’s BTC. As an alternative, the complete Bitcoin mining community approves the creation of sidechains, secures sidechains’ proof-of-work (PoW) safety, and permits sidechain contributors to peg their sidechain worth again into Bitcoin for BTC.
To be able to shield the safety of BTC from double-spending and different assaults, Sztorc proposes a six-month course of for leaving a sidechain and settling into BTC with irreversible finality.
In Drivechain, BTC transfers from sidechains to Bitcoin’s base chain use conjecture and refutation as a substitute of verifiable proof to verify the transactions. In arithmetic, conjecture describes a course of by which problem-solvers can attain the proper reply by way of deductive reasoning. Refutation refers to a way by which deductive reasoning can be utilized to exhibit whether or not a solution is appropriate or incorrect.
BIP 300: Hashrate escrows
BIP 300 describes Hashrate Escrows during which transactions from a sidechain to the primary chain are ‘signed’ utilizing hash energy as a substitute of a cryptographic key. Hashrate escrows allow a non-federated, peer-to-peer, two-way peg that enables customers to switch belongings to the sidechain after which again to Bitcoin’s base chain.
Many present sidechains use a one-way peg that enables asset transfers from the primary chain to the sidechain, however not from the sidechain to the blockchain. A one-way peg successfully ‘burns’ the belongings, rendering them unusable on the primary chain.
It mentions the motivation to create sidechains during which builders can experiment with new options with out creating one other digital asset that competes with bitcoin. Hashrate escrows present a way for compressing three to 6 months of transaction information right into a 32-byte piece of knowledge.
BIP 301: Blind merge mining
BIP 301 proposes blind merge mining, which permits mining information from sidechains with out validating the sidechain’s operations.
- With common merge mining, miners should run a full node on all blockchains to be able to validate every block.
- In distinction, blind merge mining merely permits Bitcoin miners to just accept a charge for together with non-validated sidechain information inside a Bitcoin block.
- The sidechain makes use of this Bitcoin information for numerous proofs and attestations. Nonetheless, Bitcoin miners needn’t validate any sidechain exercise.
Blind merge mining permits miners to reuse their hash price for sidechains with out working any sidechain node. Bitcoin miners don’t must take part in any sidechain exercise in any way; they merely settle for charges from sidechains to incorporate information inside Bitcoin blocks. Furthermore, blind merge mining doesn’t require that miners be paid in any altcoin; they might solely settle for BTC.
Present state of Drivechain
A testnet for Drivechain already exists — full with a Bitcoin model of zCash as a Drivechain sidechain.
Practically a decade since his authentic proposal, Sztorc stays a Drivechain evangelist. He’s continued to present Drivechain at conferences and has a brand new company known as LayerTwo Labs, which seeks the adoption of Drivechain with a consensus approval of BIPs 300 and 301 into Bitcoin Core.
Sztorc says Drivechain might have prevented numerous conflicts all through Bitcoin’s historical past. As an alternative of contentious laborious forks like BCH, these forks might have existed as their very own sidechain, accruing worth to the entire neighborhood whereas permitting unbiased growth.
Drivechain solves the feuds between Bitcoin maximalists and altcoin-curious Bitcoiners by making a BTC-denominated platform to experiment with new altcoins with out forcing the primary Bitcoin community to do something.
Disagreements can result in the creation of a brand new sidechain to work on an experimental function. Customers can merely switch their belongings again to the Bitcoin community after they’re carried out interacting with the sidechain.
In an electronic mail to Protos, Sztorc concluded, “All through Bitcoin’s historical past, folks have disagreed over what the software program ought to do. Drivechain permits the top consumer to decide on their very own software program — they’ll set their very own ‘blocksize,’ or their very own good contract stack. Bitcoin can now mimic any altcoin — thus, altcoins are out of date.”
