I m playing around with Electrum wallet, with watch only address. When i open transaction file i see text like(this is just part of it): BegDAAAAAAAAGXapFCDUWmp2JTVwDOngshbjGZQzXbiliKzoAwAAAAAAABl2qRQ+5BM9mR9S/faiXJg04HRax0JIpIis6AMAAAAAAAAZdqkU4mZG24SwYC8ys0taYso8rh+Rt3mIrOgDAAAAAAAAGXapFO9Yr7aXsJRCPOkHIfuxmjWe98UOiKwj4gQAAAAAABl2qRQqOXKrS+InhBUFWUeH0xz2br0eIoisA+AIAAABAP1PAQEAAAABVUNlt7XSzkn0QqfYv1BxvZqqMi/tiRWnHdAHoqR1rRkBAAAA2gBHMEQCIFx9Axsj2VaCBfJWg9POcLNDg5zygAVV7at8ykTYDlqbAiAcN/hNHS8jxjE7yJfuyQV/
What that means and how to read this if possible?
Thanks in advance!
