Bitcoin (BTC) professional person, author, and businessperson Andreas Antonopoulos has voiced concern relating to a attainable comprehensive consequence of the Bitcoin Improvement Proposal (BIP) 119 that he says might “kill” Bitcoin.
Proposed by Jeremy Rubin, a Bitcoin developer and founding father of Bitcoin analysis and development organization Judica, BIP-119, additionally referred to as Check model Verify (CTV), may be a soft fork proposal that aims to modify new use cases for the Bitcoin network by adding a kind of “covenant.”
A covenant is comparable to what’s referred to as a sensible contract on the Ethereum (ETH) blockchain. In straightforward terms, a covenant may be a mechanism that may modify users to enforce conditions on the manner BTC coins among a case is transferred within the future.
As of now, Bitcoin programmability is essentially restricted to the bottom level of transactions. for example, victimisation Bitcoin Script, a computer user will limit what is done before a dealing is spent. Similarly, employing a timelock, one will set a particular quantity of your time before a dealing is spent.
Covenant aims to bring a lot of programmability to Bitcoin by permitting programmers to regulate however bitcoins is spent within the future. victimisation covenant, one would be ready to whitelist or blacklist sure addresses, limiting wherever BTC is spent even for the one who has the key to those bitcoins.
Unexpected consequences
While the author of BIP-119 claims the proposal for CTV for the most part includes straightforward covenants, Antonopoulos has argued that the proposal might probably modify surprising or accidental consequences.
More specifically, Antonopoulos noted that the proposal might “kill” Bitcoin if it brings support for algorithmic covenants. A algorithmic covenant is once a computer user not solely limits consequent dealing however additionally “limits it in such the way that it limits the dealing once it, that limits the dealing once it, etc,” he said.
This would produce terribly important challenges for Bitcoin. for example, employing a algorithmic covenant, a computer user might limit the list of addresses wherever BTC might be sent within the future. This way, that specific BTC would not be fungible and would become distinct from different bitcoins that may be sent to everybody, essentially making a brand new class of bitcoins.
Moreover, once users have the power to blacklist sure addresses, there’s a high likelihood that governments and regulators would step in and begin prohibition some addresses.
“And then you’ll find yourself with primarily PayPal, solely not terribly ascendible,” Antonopoulos aforementioned. “This is however you kill Bitcoin.”
It is value noting that this can be the worst-case situation. yet, there’s a lot of difference round the proposal.
More notably, Rubin claims that BIP-119 is prepared and has asked for the upgrade to be enforced via the speedy trial method, wherever miners would have 3 or four months to signal support for the proposal. throughout this era, if quite ninety fifth of miners choose support of the proposal throughout any time {period|period of time|period} period then it’ll be activated.
However, for a proposal to be enforced, it desires huge support from users, developers, wallets, and exchanges yet – not solely miners. And if a proposal gets through while not support from of these classes, it might even end in a tough fork.
As of now, the proposal doesn’t appear to possess overwhelming support from of these classes, additionally referred to as constituencies of agreement, Antonopoulos aforementioned.
He intercalary that the proposal additionally desires in depth testing, reviewing, and auditing before it is enforced.
Echoing now of read, Adam Back, co-founder of the blockchain technology company Blockstream, aforementioned that the proposal desires an intensive review. He additionally argued that developers ought to contemplate different alternatives before continuing.
“It’s unsatisfying to envision somebody create a run at bypassing or ignoring review or regardless of the principle,” he tweeted. Back declared that there square measure “multiple alternatives that are projected on the dev-list.”
a bit lower level/more generic opcodes enabling the same or similar things, can also enable more use-cases and more flexibility, and (programming language aesthetics) fit better with bitcoin’s script design.

Similarly, Matt Corallo, additionally a Blockstream co-founder and open supply engineer at Block/Spiral, opined that the push for BIP-119 feels “wrong in precisely concerning each manner.” “Instead of cooperative engineering it sounds like “I designed this, lets do it” whereas ignoring any feedback,” he wrote.
Rubin, however, has listed variety of reasons why he thinks the proposal is effective. Among the a lot of notable blessings, the proposal would improve Bitcoin programmability, sanctionative payments to be scheduled for a particular date or multiple dates.
