   Chia Network Announces Proof of Space Competition with $100k in Total Prize Money

   Chia Team

   We’re excited to announce Chia’s Proof of Space competition. In Chia’s Proof of Space, rewards are given to farmers that can prove that they are allocating a portion of their disk space to farming Chia. In order to be used as a consensus method, Proof of Space is tied to Proof of Time. An open source implementation in C++ is available, that can be used as a starting point (opens in a new tab).

   “We’re making sure that…

   Chia Network Announces 2nd VDF Competition with $100,000 in Total Prize Money

   Chia Team

   A few months ago we wrapped up our initial VDF implementation competition and were amazed by the excellent quality of the submissions. The top three contenders each came in at under one minute (the reference implementation was 169 seconds). Five other teams also submitted implementations which were faster than the reference. All of the submissions were open-source, and can be found here. The award…

   Building a Sustainable Blockchain, With Your Help

   Chia Team

   Decentralized, digital currencies will soon evolve from being a futuristic concept to a mainstream reality. They’ll offer liquidity to those who live in countries with poorly run or corrupt central banks, and offer a universal currency for streamlined financial transfers. Currency not tied to the banking system is an idea whose time has come.

   But like any new technology, digital coins bring new…

   The ASIC Resistance of Proof of Space

   Chia Team

   A recent podcast speculated quite a bit about the economics of Chia Network’s new proof of space and time consensus algorithm.

   Let’s discuss the assertion that there are optimizations in storage technology allow for the creation of specialized Chia farming hardware that costs an order of magnitude less than commodity disks.

   Even if it were possible to make such advantaged specialized hardware, it…
