According to a recent research report, one of the creators of the Lightning Network programmer, Tadge Dryja, is working on a dynamic UTXO battery called Utreexo. The project could theoretically allow network participants to check the status of blockchain consensus rules using small sets of cryptographic evidence.
To help solve the scaling problem, MIT’s Tadge Dryja began working on the Utreexo research project. The protocol is a hash-based dynamic battery, which, in fact, reduces the size of the millions of UTXOs recorded in the blockchain to several kilobytes.
“No trusted installation or security compromises are required; instead, the burden of tracking funds is shifted to the owner of these funds, ”explains in the description of the project Tadge Dryja. “With the help of Utreexo, instead of storing all information about the state of Bitcoin, holders of cryptocurrency can simply check its accuracy by using cryptographic evidence. This will allow Bitcoin to open the way to mobile devices. ”
Utreexo Dryja and transactional battery batteries have attracted a lot of attention in recent months. In episode 1 of the Gray Mirror podcast, host Rhys Lindmark interviewed Dryja about the project, which gradually became the prototype. Tadge Dryja explained to Lindmark how blockchains can implement “without fork” updates using a connecting node via Utreexo. In addition, Stanford University cryptographers Ben Fisch, Dan Boneh and Benedikt Bünz also wrote an article that mentions UTXO batteries. The study discusses packaging techniques for batteries with interoperability applications and stateless blockchains.
With Utreexo, the protocol determines the cost of maintaining a network correctly, says the Dryja study. The millions of intranet transactions that caused many disputes could be supported by reducing the size of all existing UTXOs to a few kilobytes.
Despite the fact that battery outputs can be a long-term solution in the field of scaling, this idea has been discussed for more than nine years with little progress. Some people believe that the batteries are likely to be implemented by developers who are not so stubborn when it comes to scaling the protocol, for example, by Ethereum programmers and Bitcoin Cash.
The BTC developers have been criticized by many for their refusal to increase the block size using hard forks, while SegWit soft forks still cannot step over the 40% knot line, although more than a year has passed since its introduction. However, on December 18, the UTXO battery technology was discussed by the developers of Bitcoin Core, and on December 7, Pieter Wuille gave a UTXO battery rating. Much work remains to be done with Utreexo, but Dryja has already created a raw code. At the same time, programmers from Stanford are working on their idea, which is different from the work of an MIT engineer.
Tadge Dryja gained popularity in the cryptocurrency community as one of the creators of the Lightning Network, whose throughput in the Bitcoin blockchain exceeded 500 BTC in December. Dryja said he was working on a hash battery that stores the hash of each UTXO, reducing storage by half, back in October last year. In addition, in May 2018, Dryja and other MIT developers tested the Lightning Network with smart contracts.
