About Holo

Holochain is a post-blockchain ledger system and decentralized application platform that uses peer-to-peer networking to process agent-centric agreement and consensus systems between users. Rather than maintaining a single global blockchain, it enables each device to have its own chain-based ledger, using a holographic model for data storage and transfer so that every device on a network can function independently and data is synchronized only when necessary or agreed upon by users. The stated aim is to give users control over their own data and to change the paradigm from data-centric blockchains to an agent-centric system. According to the source text, Holochain maintains no true global consensus; instead each agent keeps a private fork managed and stored in a limited way on the public blockchain with a distributed hash table. This is described as removing scalability limits, allowing dapps to do more with less. The text also notes inherent weaknesses, stating that because the entire blockchain must be verified by each member of the network, scalability problems develop and larger data volumes restrict transactions per second. Holochain is described as open source and written in Go, with dapps developable in JavaScript or Lisp and front-end support via CSS, HTML, and JavaScript. It bills itself as an environmentally friendly alternative to traditional blockchains, consuming only a fraction of the bandwidth and having no mining component, so no electricity or processing power is spent on proof-of-work calculations. It is owned by a non-profit foundation, and its co-founders are Arthur Brock and Eric Harris-Braun.

• Holochain uses a holographic model for data storage and transfer rather than a single global blockchain.
• Each agent maintains what the source describes as a private fork, managed via a distributed hash table.
• Holochain is written in Go, chosen for its ease of use and similarity to C.
• Dapps for Holochain can be developed with JavaScript or Lisp, with front-end support using CSS, HTML, and JavaScript.
• Co-founders Arthur Brock and Eric Harris-Braun are described as having designed alternative currencies since the 1980s and working on Holo before the Bitcoin whitepaper was written.
