Bitcoin Blockchain Is Preventing Fraud In Guatemala’s Presidential Elections

Bitcoin helps safe the truthfulness of Guatemala’s election outcomes.

Due to OpenTimestamps, a device created by bitcoin developer Peter Todd a number of years in the past, Guatemalan tech startup Easy Proof is ready to safeguard key paperwork in regards to the nation’s presidential elections from fraud and tampering. Todd’s device, which leverages hash capabilities and the bitcoin blockchain, is ready to timestamp items of data and make it simpler to identify makes an attempt at fraud and manipulation.

The thought of timestamping paperwork is pretty outdated. People and societies have relied on this system for hundreds of years to point when a doc was signed, when a cheque was written, or when somebody was born. Cryptographic timestamps, nevertheless, are a lot newer. They take the idea of human timestamping a step additional by counting on math as a substitute of a fallible and corruptible human being. Signatures might be cast by subtle actors, and authorities might be topic to totally different incentives, making them able to being bribed or corrupted. Additionally, “to err is human,” whereas math makes no error if the right algorithms are used.

An instance of a great algorithm is a hash perform, a kind of mathematical perform that takes a variable sized enter to output a set size outcome. This outcome is named the hash of that enter. Hash capabilities are used within the bitcoin community, notably in blocks that get added to the blockchain, in addition to by OpenTimestamps.

How Does OpenTimestamps Work?

OpenTimestamps leverages hash capabilities to cryptographically timestamp any piece of knowledge into the bitcoin blockchain. On this case, math is being leveraged to enhance upon the usage of human signatures or attestation, and the bitcoin blockchain is getting used as a decentralized digital ledger to anchor that info, linking it to a block. This ensures tens of hundreds of nodes within the community can all independently witness the existence of the timestamp anchor and have the ability to confirm that certainly that hash was added to a block which was mined at a sure time.

OpenTimestamps works by hashing the knowledge submitted by a given consumer and including it to a bitcoin block with a bitcoin transaction. For the reason that bitcoin block’s hash is calculated leveraging all the knowledge contained in that block, the timestamping knowledge is important for the calculation of that block’s hash. In different phrases, the idea with the timestamping is that the miner should’ve essentially began with that timestamp transaction –– together with the opposite transactions contained within the block –– to reach on the block’s hash. Which means that the knowledge that was timestamped will need to have existed previous to the creation of that bitcoin block. Since each bitcoin block has a timestamp of its personal, customers can verify the date and time that block was mined and have the ability to be assured with mathematical certainty that the doc existed in a time limit previous to that block’s timestamp.

By itself, this assurance isn’t that helpful. Positive, it lets somebody show {that a} piece of knowledge existed previous to a given time limit, however how is this convenient? Properly, mixed with different sorts of info and proof, many issues might be deduced from this easy assurance. For instance, one can deduce that since that info existed earlier than that bitcoin block, any modifications to that info had been achieved after that point if its hash is totally different.

The items of data and proof needed for extra subtle conclusions should be dealt with by the consumer as a result of, finally, all that OpenTimestamps gives is the proof of inclusion of the hash of that info in that bitcoin block. Due to this fact, customers that requested the timestamp ought to preserve the unique info in hand in case they wish to show their knowledge matches the timestamp. Given the properties of hash capabilities –– the identical inputs all the time generate the identical output –– the hash would be the similar if the knowledge hasn’t been altered. Thus, it turns into fairly simple to inform if any alterations have been made to the unique info as a result of the hash could be totally different.

Beneath the hood, OpenTimestamps doesn’t put the hash of every particular person piece of knowledge being timestamped into bitcoin. That could possibly be costly, as it will require one on-chain bitcoin transaction for every timestamp. As an alternative, OpenTimestamps leverages Merkle bushes to compact that info as a lot as potential.

Much like how one can hash a big piece of data and arrive at a set size hash, you’ll be able to hash two hashes additional and get to a single hash. Likewise, you can begin with 4 items of data, hash them individually, then hash them in pairs till you’re left with just one hash. The worth proposition of Merkle bushes on this context is all about scaling this setup, the place you’ve a lot of particular person items of data and also you hash them till you’re left with one hash –– the foundation hash. OpenTimestamps takes this root hash and provides it to bitcoin, distributing the price of a single bitcoin transaction to every preliminary piece of data that was submitted for timestamping and used to assemble the tree.

Customers can nonetheless verify that their particular person hash was added, and that finally their knowledge was timestamped. They’ll leverage the OpenTimestamps web site, or go full cypherpunk and hash all the info till they attain the tree’s root hash and crosscheck with the info that’s on bitcoin.

What Does This Have To Do With Guatemala?

Guatemala has a protracted historical past of corruption and fraud amid its political circles. Easy Proof was applied in that context by ITZ DATA as an immutable backup resolution for the Guatemalan Supreme Elections Tribunal (TSE) –– the very best electoral authority within the nation.

“The Easy Proof resolution, named Immutable Backup, leverages the OpenTimestamps protocol to document proofs of paperwork in a tamper-evident method on the bitcoin blockchain,” Rafael Cordón, co-founder of Easy Proof, instructed Bitcoin Journal. “TSE used Easy Proof to safeguard official election paperwork and shield important info from synthetic intelligence and disinformation, guaranteeing that any tampering of paperwork is made evident and any citizen can independently confirm the knowledge for themselves.”

Guatemala’s residents can verify any given tally sheet and confirm its proof of timestamp via a devoted internet portal. Every sheet comprises the sum of votes for every candidate at a voting ballot. Due to this fact, transparency is offered to the inhabitants relating to the tally sheets that had been scanned and used to depend the votes, in addition to when every tally sheet was timestamped.

It is very important word that this setup can’t attest whether or not a given tally sheet is legitimate or not; there may be nonetheless a belief assumption in direction of TSE. Nonetheless, it’s an enchancment over simply taking officers for his or her phrase, as it’s, for instance, simpler to identify outliers amongst all of the tally sheets. Fairly than having the ability to inform voters particular validity info for any single tally sheet, OpenTimestamps permits an outline of the whole context of the elections.

For instance, it arguably shouldn’t take greater than an hour after voting ends to scan a tally sheet, add it to Easy Proof’s resolution, and get it timestamped right into a confirmed bitcoin block. If nearly all of tally sheets fall inside that hour however a number of had been timestamped for much longer after the closing of votes, it’s cheap to imagine that these outlier sheets have a a lot higher probability of being fraudulent than the opposite ones. In different phrases, within the occasion {that a} tally sheet was entered a lot after it was presupposed to, the timestamps are going to let you know that it’s suspicious that it took that lengthy to timestamp the sheet after the polls closed quite than lower than an hour later.

This was and nonetheless is being specifically essential within the context of Guatemala’s elections due to the stress there was main as much as the race, in addition to the outlier candidate who ended up successful it. President-elect Bernardo Arévalo wasn’t anticipated to even qualify for the principle race months earlier than it befell.

As soon as Arévalo gained the presidential election, the outcry was huge. Officers from the workplace of the nation’s legal professional basic, María Consuelo Porras, raided amenities of the TSE, opening dozens of containers of votes, per AP. The opposing social gathering, UNE, claimed the victory was fraudulent and demanded a vote recount.

UNE posted a thread on X explaining their rationale with some alleged proof –– together with a screenshot of 1 tally sheet on Easy Proof’s internet device that confirmed it was timestamped earlier than the polls closed.

Both in an try to push their narrative or by mistake, the screenshot of that tally sheet was taken on a unique timezone than the nation’s capital official time, resulting in the one-hour distinction. On this particular case, bitcoin helped make sure the claims made by UNE had been false, and any citizen was in a position to confirm it by checking the timestamp on their pc. Notably, one did –– publishing a screenshot on X rectifying that the tally sheet UNE claimed had been tampered with had really not been timestamped too early.

Whereas bitcoin was designed and developed solely to unravel the double spend drawback and obtain digital peer-to-peer cash, its community of nodes and decentralized ledger can energy different attention-grabbing use instances.

On this case, it’s evident how Easy Proof performed an essential function in defending key election info. Had OpenTimestamps and bitcoin not been part of the method of securing that info in a cryptographic, public and decentralized method, there might’ve been a a lot larger outcry and tumultuous procedures to attempt to make sure the knowledge hadn’t been tampered with. Doubts would almost definitely nonetheless persist, and in a rustic with a historical past of fragile democratic procedures, the shaking of confidence might deter the president-elect’s capacity to guide the nation as its rightful new chief.
