Bitcoin Cash Smart Contracts ‘Comparable to Those on Ethereum’ Possible via May Upgrade, ‘1000x Efficiency Advantage’: Dev Jason Dreyzehner

Pro-freedom technologies advocator and bundle developer Jason Dreyzehner precocious spoke with Bitcoin.com News via email astir the upcoming Bitcoin Cash web upgrade connected May 15. One of the astir talked astir betterment proposals acceptable to spell done connected that day — which proponents presumption arsenic a boon to economical state — is the Cashtokens CHIP. Beyond UTXO-level token creation, the upgrade volition let for “advanced on-chain applications similar higher-security vaults, decentralized exchanges, and bridged sidechains,” comparable to ethereum, much scalable, and cheaper, according to Dreyzehner.

Bitcoin Cash Dev Dreyzehner connected Cashtokens Upgrade

As the accepted fiscal satellite is focused connected cardinal slope integer currencies, slope failures, and trying to modulate permissionless integer assets, bitcoin currency enthusiasts are looking guardant to the May 15th upgrade, which features a Bitcoin Cash Improvement Proposal (CHIP) known arsenic the Cashtokens CHIP.

BCH Tokyo play meetup organizer Big V told Bitcoin.com News: “The Cash Tokens upgrade is breathtaking due to the fact that it is 1 tiny measurement for the protocol, but 1 elephantine leap for Bitcoin Cash which present enables incredibly fast, businesslike and inexpensive decentralized permissionless fiscal products for everyone connected Earth.”

Beyond enabling tokenization, which has been attempted successful a little integrated mode earlier with SLP tokens, the Cashtokens CHIP allows the BCH web to beryllium utilized arsenic ne'er before, enabling onchain UTXO-based astute contracts and decentralized exchanges, which according to developer Jason Dreyzehner, committedness to beryllium remarkably much scalable and affordable than those connected different chains specified arsenic Ethereum.

Bitcoin.com News precocious reached retired to Dreyzehner via email to larn much astir this upcoming alteration to the network. Below are his responses.

Bitcoin.com News (BCN): It whitethorn beryllium a gangly order, but successful conscionable a fewer sentences, could you archer maine wherefore the Cashtokens CHIP could beryllium a crippled changer for Bitcoin Cash?

Jason Dreyzehner (JD): Cashtokens are integer assets with the censorship-resistant, peer-to-peer, low-fee properties of Bitcoin Cash. Cashtokens tin beryllium issued by anyone, and they tin some correspond carnal assets and straight service arsenic currencies, outgo stablecoins, commodities, securities, indebtedness instruments, acquisition cards, receipts, lawsuit tickets, and more. The underlying exertion besides enables acold much precocious on-chain applications similar higher-security vaults, decentralized exchanges, and bridged sidechains.

BCN: Could astute contracts connected the BCH concatenation yet beryllium comparable to those connected Ethereum?

JD: Yes. Cashtokens alteration decentralized applications connected Bitcoin Cash comparable to those connected Ethereum, portion retaining Bitcoin Cash’s implicit 1000x ratio vantage successful transaction and artifact validation.

Ethereum developers tin deliberation of Bitcoin Cash arsenic featuring transaction-level sharding of some information and execution, relationship abstraction, deterministic state pricing, all-or-nothing transaction chaining, zero-delay re-spending, a wider enactment of MEV-resistance strategies, and no-fee declaration deployment – idiosyncratic wallets some “deploy” and “destroy” contracts incrementally arsenic portion of their usage, improving wide web throughput and real-world privacy. All of this exists astatine “layer 1”, with exceptionally low-bandwidth transactions, low-resource archival nodes, ever-improving scalability (already 25,000 transactions per 2nd connected modest, 2020 hardware), and aggregate strategies for “layer 2” systems if needed (e.g. Lightning Network would beryllium more bandwidth-efficient connected Bitcoin Cash than connected BTC).

The tradeoff betwixt Ethereum and Bitcoin Cash is improvement complexity: Ethereum contracts usage a simpler, single-threaded, global-state exemplary vs. the multithreaded, stateless-validation exemplary utilized by Bitcoin Cash, truthful Ethereum contracts are easier to make but acold much costly to use. This architectural quality allows decentralized applications built connected Bitcoin Cash to standard to millions of users without expanding transaction fees, adjacent during periods of precocious web activity.

BCN: How does the Cashtokens CHIP disagree from the Simple Ledger Protocol tokens implementation?

JD: Simple Ledger Protocol v1 (SLPv1) requires wallets to unreal that tokens beryllium connected concatenation utilizing a modular acceptable of off-chain rules. The rules are computationally costly to follow, and successful practice, they propulsion astir airy clients to usage trusted servers. SLPv1 tokens besides cannot beryllium seen by on-chain contracts, truthful decentralized exchanges, sidechain bridges, and different on-chain applications would necessitate systems for consulting trusted entities astir the authenticity of SLPv1 tokens.

In contrast, Cashtokens fundamentally beryllium connected the blockchain, are disposable to contracts, and necessitate negligible computation for some nodes and airy clients to verify their authenticity. This enables trustless, decentralized applications to enactment with and adjacent contented tokens themselves, opening up wholly caller capabilities for contracts to interoperate with different contracts.

Beyond this aboveground level, it’s hard to comparison Cashtokens and SLP directly. Cashtokens are present a low-level diagnostic of Bitcoin Cash, portion SLP is simply a wider acceptable of wallet standards including however tokens should beryllium issued and used. Future SLP specifications could make upgrade paths for SLPv1 tokens to inherit the low-level benefits of Cashtokens portion preserving different SLP features.

BCN: You person spoken antecedently astir literal lives being perchance saved — and tons of them — acknowledgment to prediction markets which the May upgrade could besides marque possible. Can you expound connected this?

JD: I’ve written astatine magnitude astir this successful Prediction Markets connected Bitcoin Cash, truthful beryllium definite to cheque that retired too. To summarize, prediction markets alteration trading connected the result of events, crowdsourcing and aggregating immense quantities of accusation into elemental probabilities. In the afloat essay, I locomotion done the ways I expect prediction markets to interaction assorted industries, however they mightiness beforehand bid and prosperity by exposing organized transgression and organization corruption, and wherefore I deliberation Bitcoin Cash is uniquely suited to beryllium a reserve plus for prediction markets.

Now that we person Cashtokens, it’s yet imaginable to physique low-fee, censorship-resistant prediction markets connected Bitcoin Cash. This volition beryllium nary tiny feat; it volition apt beryllium respective years earlier specified markets are up and running, but it’s precise breathtaking that developers present person a stable, permissionless, low-fee level to physique and motorboat solutions without further upgrades to Bitcoin Cash.

BCN: How did you observe that the UTXO exemplary could beryllium utilized for astute contracts?

JD: To clarify, I’m not the archetypal to observe that the UTXO exemplary tin beryllium utilized for astute contracts, Cashtokens simply connection a caller approach. Satoshi designed astir of the Bitcoin Cash virtual instrumentality (VM) earlier publishing the archetypal bundle implementation successful 2009, and helium seems to person had a imaginativeness for overmuch of the UTXO-based declaration space. Recent upgrades to Bitcoin Cash widen connected Satoshi’s VM successful ways that I expect helium mightiness person discovered if he’d continued moving connected it. In fact, galore ideas considered “new” successful this abstraction person been independently discovered and rediscovered galore times successful the past 10+ years. You tin get a consciousness for immoderate of that past arsenic it relates to Cashtokens successful the Prior Art & Alternatives conception of the proposal.

In my opinion, the cardinal find successful Cashtokens is the method conception of contract-issued commitments – irrevocable messages that are provably issued by a peculiar entity; connected Bitcoin Cash, we telephone these messages “non-fungible tokens” (NFTs). I archetypal noticed the request for this message-passing behaviour while designing a sidechain bridge for a prediction marketplace connected Bitcoin Cash. I recovered myself reusing the aforesaid conception of codification (requiring the PMv3 proposal) successful a wide assortment of contracts to store and walk these commitments around, arsenic good arsenic a larger codification conception to enactment splitting and merging of commitments holding numeric values (“fungible tokens”). When I experimented with factoring retired that codification into built-in VM behavior, I discovered that the alteration some reduced declaration sizes by an bid of magnitude and resolved a astonishing fig of different VM limitations. Suddenly it was imaginable to physique precise efficient, UTXO-based decentralized applications portion preserving important features of Bitcoin Cash: stateless transaction validation (low fees) and zero-delay re-spending (fast transactions).

BCN: Is determination thing other you privation to accidental astir the May upgrade, BCH, oregon crypto successful general?

JD: I expect the adjacent fewer years to beryllium precise breathtaking for some Bitcoin Cash and for the wider abstraction of peer-to-peer money.

Globally, peculiar interests question to enforce Central Bank Digital Currencies (CBDCs) and widen their power implicit each transactions, jeopardizing quality rights connected a previously-impossible scale. Financial state is progressively the instauration connected which different freedoms rest; the close to assemble, peacefully protest, a just trial, etc. – these connection small extortion if you tin beryllium instantly excluded from moving oregon buying nutrient erstwhile you workout those rights. At the aforesaid time, caller events person revealed systemic failures successful immoderate of the aforesaid institutions that led Satoshi to enactment connected peer-to-peer wealth successful 2008.

Even extracurricular of our ecosystem, tenable radical stock our concerns with centralized money. Our neighbors request alternatives present much than ever, and we tin amusement them however free, fair, and resilient wealth works. Keep building.
