Bitcoin Cash to change the address

New address format was proposed by Amory Sechet from Bitcoin ABC in October 2017

The ecosystem of Bitcoin Cash (BCH) is being prepared for the "Address Change Day", which is scheduled for January 14 next year. This is written by

The Bitcoin Cash network and companies supporting this crypto currency will switch to the new Cashaddr address format, based on the Bech32 code base. It was proposed by the Bitcoin ABC developer Amory Sechet in October this year and, in particular, is designed to prevent Bitcoin Cash from sending to bitcoin address.

Also, the new format will provide the possibility of implementing a number of improvements and new functions in the protocol. For example, Cashaddr will create conditions in the future for the implementation of the concept of evidence with zero disclosure (Zero-Knowledge Proof) in the Bitcoin Cash network. In addition, new addresses will create conditions for implementing improved checksums and QR encoding.

In order to reduce confusion for users with the use of different addresses, I think it is important to deploy this shortly and stop the fragmentation of the ecosystem. Deploying such a change on the network will take some time for all the wallets, exchanges and merchants to upgrade. We will support Bech32 for bitcoin cash on January 14th. We’ll provide a simple converter as well so users can convert the deposit address to the current format — Withdrawals will work to both formats.

The developers of the Blockchair blockchain, the Openbazaar project, Stash, Edge and Electron Cash wallets have already started preparing for the transition to the new address format. Also on the support of Cashaddr reported P2P-platform BTCpop.

This Monday, the Chinese mining company Bitmain announced the next-generation 7-nm chip codenamed BM1397, which, according to it surpasses its predecessors in performance and energy efficiency and is suitable for mining cryptocurrencies on the SHA256 algorithm, including Bitcoin and Bitcoin Cash.

The BM1397 chip requires less energy and is able to achieve efficiency at 30J / TH, which is “higher by 28.6% than the previous 7-nm chip from Bitmain”, codenamed BM1391.

BM1397 is manufactured using TSMC, a Taiwan-based semiconductor product company, which is one of the leading suppliers in the cryptocurrency mining industry.

The BM1397 chip will be installed in the new ASIC miners of the Antminer S17 and Antminer T17 models, the release of which Bitmain promises to announce later. The company does not provide other details of the updated devices in its message.
