Bitcoin’s ongoing scaling debate continues to highlight that protocol governance is 1 of the biggest challenges for this technology.
One of the many solutions that conduct hold been proposed to intermission through the scaling impasse is coin-voting schemes, where Bitcoin users larn to “vote” on potential protocol changes amongst their bitcoins. One implementation of such a solution, Bitcoinocracy, already exists, spell several Bitcoin Core developers conduct hold been working on alternative schemes.
And recently, Bitrated CEO Nadav Ivgi developed an early on implementation of HODL.voting, a coin-voting solution amongst an interesting twist. To vote, users take away to lock upward their bitcoins, losing access to them for or hence time.
“The theory is that yesteryear attaching a existent toll to voting — loss of liquidity as well as might to sell — nosotros tin sack larn to a greater extent than reliable signaling,” the Israeli developer thinks.
Sacrifice
The concept behind existing coin-voting schemes similar Bitcoinocracy is simple. Anyone who holds bitcoins tin sack role the associated private keys to sign a message. This message acts equally a vote, as well as all votes are added up. This definitively proves that all votes stand upward for to the ownership of bitcoins, allowing for a one-coin-one-vote type of system.
But this straightforward setup likewise has its weaknesses, Ivgi argues. Most important, spell this type of voting requires access to bitcoins, it soundless doesn’t genuinely toll anything to vote.
“This way that custodians — exchanges, hosted wallets, etcetera — larn to conduct hold disproportional voting might amongst their customers’ funds. And I don’t recall that people currently belongings funds at an central meant to consent to the central voting on their behalf on matters such equally this,” Ivgi explained. “And two: cost-free signaling is non rattling reliable. Someone who’s non informed on a debate has no incentive non to vote even hence he feels like, fifty-fifty if he knows that the vote is completely uneducated. Alternatively, it would move rattling inexpensive to bribe him to vote a surely way, peculiarly if he’s non planning to vote otherwise.”
The solution to this problem, Ivgi thinks, is to add together a toll to voting. Referring to the handicap principle, he suggests that whenever there’s an incentive to cheat, requiring a kind of “sacrifice” tin sack brand signaling to a greater extent than reliable. Anyone who wants to vote would conduct hold to incur a existent toll to bear witness that he genuinely way it.
The toll that HODL.voting imposes on voters is a lack of access to their actual bitcoins, temporarily. And the longer soul is willing to lose this access, the to a greater extent than weight is attributed to the vote.
“HODL.voting uses fourth dimension locks equally a sacrifice to assign votes amongst weight,” Ivgi explained. “You ship bitcoins to a special Bitcoin address that locks your bitcoins upward as well as encodes your vote. The vote is weighted according to the amount of bitcoins locked, multiplied yesteryear the lock duration.”
And this likewise has the benefit, Ivgi pointed out, that custodians can’t vote for their customers; non without effectively running a fractional reserve. Users may desire to withdraw their bitcoins at whatever time, hence making them inaccessible shouldn’t move an choice for exchanges as well as wallet providers.
HODL.voting
Ivgi developed an early on implementation of HODL.voting at the Tel Aviv Bitcoin Embassy Hackathon final March — as well as won commencement prize amongst it.
The implementation uses CheckSequenceVerify (CSV), a characteristic that was added to the Bitcoin protocol almost a twelvemonth ago. CSV allows users to essentially “lock” bitcoins into the Bitcoin blockchain itself. H5N1 transaction that spends these bitcoins would move considered valid alone at or hence request inwards the future, relative to when the bitcoins were “locked up.”
Using the HODL.voting website, voters tin sack practise a transaction that locks upward their bitcoins amongst CSV. The website likewise generates a refund transaction, which volition alone move valid at or hence request inwards the future. HODL.voting users tin sack broadcast this transaction when the fourth dimension lock has passed — or conduct hold it broadcast for them. Consequently, the voter volition conduct hold lost access to his coins for or hence time, enforced yesteryear the Bitcoin protocol itself.
And the transaction that locks upward the bitcoins likewise contains or hence extra data: the “vote.” The HODL.voting website recognizes the information equally a vote, to tape it as well as add together it to all other votes to calculate the overall score. That grade is as well as hence visible on the HODL.voting website itself.
The alone existent weakness left is that whoever controls the website could fuzz the visible score. While the actual vote cannot move faked — it’s embedded as well as enforced yesteryear the Bitcoin protocol — what visitors come across on the website equally the resultant tin sack be. That said, it should move possible for private voters to verify whether their vote was included inwards the overall results. And, whatever interested political party tin sack verify that all the votes equally displayed on the website are legitimate. This should maintain the platform honest, Ivgi thinks.
Lastly, it should move noted that HODL.voting is, of course, non inwards whatever fashion binding for anything — it’s genuinely to a greater extent than of a polling mechanism. But equally a poll that cannot move faked, it could supply useful information that is otherwise difficult to come upward by.
Ivgi:
“I recall that equally a voting organisation it’s by as well as large interesting for gauging community persuasion regarding Bitcoin protocol evolution issues. It gives the voting might to long-term holders who’re willing to bear witness that they’re confident inwards Bitcoin’s long-term value proffer as well as that they conduct hold a stake inwards Bitcoin. Not merely today, but likewise inwards the futurity value of Bitcoin equally affected yesteryear the protocol evolution decisions they’re voting on.”
An alpha version of HODL.voting is currently running on Bitcoin’s testnet. Ivgi says there’s soundless quite a combat of operate to move done earlier the projection volition move laid for the mainnet. He volition consummate HODL.voting if he believes at that topographic point is plenty involvement for it.
