Bitcoin hardware wallet Trezor announced today on their official blog that they are moving away from their proprietary closed source backend server to the open source supported Bitcore server.
The move according to SatoshiLabs, the maker of Trezor, was done so that users do not have to depend on SatoshiLabs’ servers availability anymore. In case of a server downtime, users may switch to another Bitcore server within few seconds.
Bitcore by BitPay is an opensource bitcoin blockchain indexing service used by numerous companies (not to confuse with Bitcoin Core, the bitcoin peer-to-peer node implementation). In the blog post Trezor says,
This release allows the users to choose a different server instead of the official server run by SatoshiLabs. Advanced users can choose to use their own backend server, effectively avoiding to leak financial information to any third party.
In addition to the change, Trezor developers submitted a minor bug fix to Bitcore’s code necessary for proper wallet functionality. Gradually, as other Bitcore node operators accept the fix, Trezor will be adding more predefined server options. Hopefully they will continue to help contribute to the Bitcore open source code.
In the past year there has been a slew of bitcoin hardware wallets to hit the market, rising to increased competition in this area of bitcoin development and business.
