Gregory Magarshak is founder and CEO of Intercoin. Since 2011 he has constructed a decentralized social networking platform that has reached 7 million customers so far, and is engaged on instruments to assist carry energy again into the palms of folks and native communities.
For each expertise we use as we speak, there was a time it was laughably insufficient as a substitute for what got here earlier than. For many years, chess engines had been a mere curiosity, however now a sensible telephone can beat any grandmaster. The identical is now true of voting expertise.
As we glance again on the current failures of apps to safe our elections, from failing in Iowa to a couple days later leaking thousands and thousands of voter information in Israel, we’re reminded that expertise, particularly within the palms of smaller contractors, will be fallible, and result in large information leaks.

Many individuals say we don’t want tech to safe our elections, that paper ballots have been ok for hundreds of years. However is that basically true? George W Bush gained in 2000 not as a result of he bought extra delegates in the long run, however as a result of the recount of paper ballots took so lengthy that the Supreme Court docket needed to step in and decide. The Iraq Struggle might have by no means occurred if we didn’t use paper ballots. The current coronavirus epidemic additionally raises well being considerations about shared voting amenities versus utilizing private touchscreen gadgets.
Crypto and “Byzantine Consensus” was imagined to lastly safe our elections. However to date dominant blockchains like bitcoin and ethereum haven’t been scalable sufficient to deal with thousands and thousands of folks paying, or voting, suddenly.
For each expertise we use as we speak, there was a time it was laughably insufficient as a substitute for what got here earlier than.
However a brand new technology of open supply innovation and protocols like Intercoin, MaidSAFE and Holochain, is exhibiting easy methods to construct provably safe, scalable infrastructure that may deal with voting and economies at scale.
These new protocols are usually not primarily based round a monolithic blockchain and wouldn’t have a central bottleneck similar to a “miner” or a “mining pool.” As a substitute, every entity (a coin, a file, or group exercise) is secured by a small subset of the entire community, known as a “shard” or a “part.”
A lot of this expertise will not be new. In reality it predates bitcoin. BitTorrent and different peer-to-peer file sharing programs are primarily based on a way known as Kademlia, developed in 2004. These sorts of sharded networks can scale indefinitely, their embarrassingly parallel structure supporting a virtually limitless quantity of simultaneous transactions. The networks are usually not simply peer-to-peer, but additionally have the flexibility to mixture outcomes, for voting and different neighborhood functions. And all of that is carried out with out “layer 2” options, that are virtually all the time centralized “cop-outs” from an in any other case trustless infrastructure.
Conventional networks are susceptible as a result of belief is concentrated in a single place – whether or not cash, information or votes. This makes it economically engaging for each exterior and inner actors to attempt to subvert the ensures we’ve come to depend on. Dillinger didn’t waste his time robbing piggy banks. Manufacturers gained’t purchase private information from random websites with 20 customers.
A bitcoin pockets comprises endlessly divisible balances (known as “UTXOs” in bitcoin parlance). As a result of of this limitless division, every full node should maintain all the historical past of each transaction, simply in case some of these balances might have come from faux transactions.
An ethereum pockets comprises token balances saved inside a sensible contract on an ethereum community. As increasingly more cash is exchanged for this token, its complete provide turns into very beneficial and the good contract turns into a gorgeous goal for malicious actors. This is the reason it has been so exhausting to shard ethereum. If, for instance, every good contract was secured solely by a couple of nodes, then sooner or later it might grow to be economically engaging to assault this consensus, both to alter some balances or simply stop additional progress and kill the token. Both means, it’s a unhealthy final result for the community.
Intercoin wallets, then again, maintain cash, every one price little or no and watched by a small, successfully random group of nodes. Paying precise change is achieved by cash of denominations of 1/2, 1/four and so forth down, and interacting with “change bots” – accounts that alternate a coin for an equal quantity of change. Cash on the MaidSAFE community (known as “safecoins”) work equally.
The secret is, there’s a pure restrict on how a lot particular person cash are price. There aren’t any UTXOs or Token Contracts price $50 Million. To assault the consensus, an attacker must infiltrate and subvert most or all of the nodes in a single explicit shard (known as a “part” in MaidSAFE), however all they’d take over is one small coin. To achieve any important quantity of worth, they’d must assault a proportional quantity of the community. Every particular person assault turns into increasingly more troublesome because the community grows, not to mention the mixed assaults to internet something of worth.
This implies massive transactions should contain massive transfers of cash, simply as ransom and drug offers in motion pictures are carried out with massive suitcases of $100 payments, every one presumably not trivial to acquire. Thus, such networks are suited to smaller, on a regular basis funds with proportional charges, fairly than storing and transferring big quantities of worth for a set price. The place bitcoin and ethereum assist retailer worth, Intercoin and Maidsafe allow the opposite aspect of cash – a scalable means of alternate.
So, how does that assist us belief our elections to an app? The reality is, blockchain expertise will not be sufficient. You must string collectively a number of options directly, together with a means of distributing one token to every voter; Merkle Timber (or hash bushes) that file info sequentially and permit multi-person verification; embrace a number of impartial distributors, so voters can examine, from totally different “consumer brokers”, their vote recorded on the Merkle Tree; and personal keys for each voter.
The crypto neighborhood has already carried out a lot of this equipment to safe extra beneficial issues than a single vote. Ethereum, for instance, is constructed on a blockchain secured by many mutually distrusting events. Individuals might belief their favourite pockets consumer, however they can even confirm utilizing one other pockets or an online primarily based blockchain explorer similar to Etherscan. The probabilities of all these entities colluding to steal somebody’s tokens grow to be smaller as extra purchasers software program is launched and extra miners safe the back-end community.

In the direction of the underside of the Merkle Tree, on the extent of particular person precincts, particular person outcomes don’t signify juicy targets to subvert. The payoff is small – 1 % of an Iowa delegate, maybe. By the point the outcomes have been entered on larger ranges of the tree, although, they’ve been checked by a rising pyramid of a number of distrusting events on each decrease stage, and stuck in a means that by then is mathematically infeasible to reverse.
Every particular person voter would be capable of file their Merkle Department, with a view to examine that their vote was recorded and counted accurately. At every stage within the tree, mutually distrusting witnesses agreed that they got here collectively and recorded a consequence accurately. With info being deleted at each step, nobody can confirm how another person voted, until that different particular person chooses to disclose their vote and Merkle department. A system might even be constructed the place voters can furnish confidential zero-knowledge proofs of how they voted, with out the recipients with the ability to show it to anybody else.
In a means, bitcoin and ethereum are like MySpace and Friendster – the primary iterations of a brand new trade that may sort out trustless computing in more and more subtle issues. Ethereum’s blockchain is monolithic, utterly public and anybody can examine something. But when new expertise will carry down the associated fee of operating elections you may belief, then each group massive and small will wish to do one. And so they might not need everybody to know the outcomes – they might need privateness contained in the group.
Crypto can liberate folks to kind communities and get issues carried out while not having handy over large quantities of belief and management to 3rd events.
This set of necessities for privateness calls for extra improvements which are actually beginning to be carried out by the crypto neighborhood (right here “crypto” is being utilized in its authentic sense, that means cryptography), together with group encryption, group signatures and end-to-end encryption, the place analysis is ongoing about easy methods to effectively carry out mathematical operations on encrypted information with out realizing the unique values.
We might by no means utterly get away from having to belief some entity that tries to make sure every particular person isn’t utilizing a number of identities to vote, however research have proven that this occurs exceedingly not often when folks vote in particular person. As persons are capable of vote from their sofa, away from prying eyes, we might come to rely increasingly more on “verified identification” providers to unravel this remaining safety difficulty. Efforts to standardize and innovate on this space are ongoing and maybe at some point we are going to even be capable of obviate this last must belief third events.
However till then, initiatives like Intercoin, Holochain and MaidSAFE signify a means ahead for decentralized crypto infrastructure to lastly allow us to as a society have interaction in funds, voting, governance, and different scalable actions. Expertise and crypto can liberate folks to kind communities and get issues carried out while not having handy over large quantities of belief and management to 3rd events.
