It's Possible to Increase Bitcoin's Block Size Without a Hard Fork: Blockstream Co-Founder

Mark Friedenbach, a bitcoin developer and co-founder of the popular Blockstream company, has recently revealed a scaling approach he called “forward blocks,” which could essentially help increase BTC’s block size without a hard fork.

Currently, bitcoin can accommodate a small number of transactions per second, and is unable to compete with traditional payment networks such as that of Visa. While some believe the cryptocurrency should scale through a block size increase – which would require a hard fork - others argue this approach will lead to centralization, and prefer other solutions.

A hard fork is essentially a change to the network that isn’t backwards-compatible, meaning all of the cryptocurrency’s users need to upgrade to keep up with the change. A soft fork, on the other hand, can be backwards-compatible.

Friedenbach’s approach, according to a transcript of his presentation at the Scaling Bitcoin workshop, would be able to boost the flagship cryptocurrency’s on-chain transaction capacity through a Proof-of-Work (PoW) alternation achieved through soft forks and “privacy-enhancing alternative ledgers (side chains).”

According to Friedenbach, a former space apps developer at NASA, the forward blocks approach could ultimately help increase the cryptocurrency’s “settlement transactions volume to 3584x current levels,” while improving censorship resistance via sharding.

Here, the developer refers to sharding as a change to the PoW system and a series of developments that would see bitcoin’s blockchain scale. Most cryptocurrency users refer to sharding when mentioning Ethereum’s scaling solution, which would see multiple network computers divide transaction workload between them to scale the blockchain. These two, per Friedenbach, are “largely not” the same.

Speaking to CoinDesk, the former NASA employee noted his approach could help with the scaling debate, as the community often opposes hard forks because of how hard it can be to do them safely. He was quoted as saying:

Forward blocks makes that whole argument pointless. We don't need a hard-fork to scale bitcoin, if and when we decide to do so. It can be accomplished as a soft fork, like SegWit was.

SegWit, as CryptoGlobe covered, was launched one year ago and recently saw its usage go over 50%. During his presentation, he further suggested it could be good to replace bitcoin’s current halving mechanism, which halves block rewards every four years. To him, a more linear approach could be more beneficial to the cryptocurrency, as it wouldn’t suddenly affect the ecosystem.

Notably, Friedenbach reportedly got to his forward blocks approach by starting out thinking about a “development of a dual PoW change where you introduce a new PoW with a soft fork.” While he noted this wasn’t a proposal, it’s a “good place” to start thinking about the solution.

 

A Controversial Solution

While some could look at the former NASA contractor’s approach as revolutionary, CoinDesk reports not everyone is excited about it. Pseudonymous bitcoin developer “Shinobimonkey” was quoted as saying it was a “network attack being called an upgrade.”

Blockstream’s CEO Adam Back noted that “it’s OK,” as discovering mechanisms “can be useful and separate from whether it would be practical technically and in terms of user consensus.” To him, it’s so far just another tool.

Per the news outlet, Friedenbach isn’t advocating to use forward blocks on bitcoin either, but is merely trying to put the option out there. He’s reportedly set to test it on “Freicoin,” an altcoin he created.

Block.One’s New Social Media Platform Voice Briefly Launched Ahead of Schedule

  • Block.One's new social media platform Voice launched briefly ahead of schedule.
  • The blockchain-based platform made its official release on July 4th, placing an emphasis on real user connections. 

The blockchain-based social media platform Voice briefly went live a day ahead of its scheduled launch on July 4th. 

Voice, developed by EOSIO creator Block.one was originally scheduled for launch on the United State’s Independence Day. However, the project briefly went live on July 3rd, with the platform’s main page temporarily displaying posts from several different accounts featuring likes and comments. 

The website was subsequently pulled, with the page displaying an “Error 1020” message in the interim. 

Desipte the miscue, the social media platform was able to initiate its official launch the following day with the iOS app also being made available. 

As previously reported, Voice pivoted its planned launch date in Fall 2020 to July in response to global social unrest. The new platform, which utilizes blockchain technology and biometric authentication to cut down on the number of spam users, has placed an emphasis on real interactions, news, and connections.
